1. Introduction
Thank you for purchasing the LINDY Dual/Quad PRO. Your LINDY Dual/Quad PRO
is a very high performance Keyboard, Video monitor and Mouse (KVM) sharing
device which supports a wide range of PC hardware and software platforms. The
LINDY Dual/Quad PRO supports multiple users and enables each user to
independently access the connected computers.
An On-Screen-Display (OSD) menu system is provided for easy computer selection
and control. This enables users to select computers by name or description without
having to remember the port that the computer is physically connected to. The OSD
menu system also provides a security structure that enables the system
administrator to allocate access rights to each user on a login basis.
LINDY Dual/Quad PRO products are fitted with one (2) or two (4) dual access user
ports. These dual access ports have both traditional KVM connectors for local
keyboard, monitor and mouse connections and an RJ45 link for connection to a
remote LINDY extender unit. This gives the user the ability to connect to the LINDY
Dual/Quad PRO from up to 200 metres away using common twisted pair network
cable whilst still having the ability to access the LINDY Dual/Quad PRO using a
local KVM console.
We trust that you will be delighted with the function of your new LINDY Dual/Quad
PRO. We are always interested to hear any suggestions that you may have for
additional features or functionality (email to: [email protected]). Product
enhancement upgrades are provided free of charge during the warranty period and
benefits that are offered by your LINDY Dual/Quad PRO are listed in section 1.1
LINDY explains:
What does KVM stand for?
Throughout this manual the abbreviation KVM is used to refer to the combination of
a Keyboard, Video monitor and Mouse that is used to access a computer. A KVM
console usually consists of a keyboard, monitor and mouse although sometimes
only a keyboard and monitor may be used. Devices such as the LINDY Dual/Quad
PRO are generally known as KVM sharers or KVM switches.

2. Installation
LINDY explains:
Flexible configuration
The LINDY Dual/Quad PRO has many ports for connection to computers,
keyboards, mice, monitors and LINDY Link extenders. There are no restrictions
placed upon which ports are connected to devices and you can leave any of the
ports disconnected if you wish. You do not need to connect a keyboard, monitor and
mouse to each user port if you do not wish to use all of these. You may perhaps
decide to connect just a keyboard and monitor or you may decide to connect to just
one user port. All of these configurations are supported. What's more, your devices
do not all need to be of the same type. You may wish to use a large high-resolution
monitor with an extended keyboard and a wheel mouse on one user port and a
smaller monitor with a basic mouse and keyboard on another. The LINDY
Dual/Quad PRO intelligently handles these mixtures of devices.
2.1 What you will need
For the computer connections you will need:
Cables to connect the LINDY Dual/Quad PRO to each of your computer
keyboard, video and mouse ports. Cable specifications are given in appendix A.
LINDY 3-in-1 keyboard / video / mouse combination cables are particularly
recommended for neatness, convenience and video quality. (You do not need to
connect a mouse cable if you are not using the mouse).
A suitable mouse driver for your PCs. Supported types are:
- PS/2 or RS232 two button mouse driver (any manufacturer).
- Microsoft mouse driver (including IntelliMouse).
- Logitech mouse driver (including two button, three button and wheel mouse).
- General mouse drivers that are supplied with the operating system.
For the local user port connections you will need:
A monitor with a standard VGA-style 15-pin analogue video connector that will
work when connected directly to each of your PCs. LINDY Dual/Quad PRO supports
low and high resolution monitors.
LINDY Dual/Quad PRO
Installation and Use

A PS/2 or AT style keyboard. If you are using an AT keyboard with a 5-pin
connector you may connect this to the LINDY Dual/Quad PRO using a standard AT
to PS/2 keyboard adapter. LINDY Dual/Quad PRO supports standard keyboards
and keyboards with extra media control and Internet navigation keys.
All LINDY PS/2 Mice and PS/2 style two or three button Microsoft or Logitech
compatible mouse or a Microsoft IntelliMouse compatible mouse. If you wish to use
the mouse to switch the LINDY Dual/Quad PRO's channel then you will need a three
button mouse or an IntelliMouse.
(The LINDY Dual/Quad PRO supports ‘Internet / scroll mice’ that are compatible with
the Microsoft IntelliMouse. These are fitted with a wheel or other scroll control and
sometimes have additional buttons. Examples are: Microsoft IntelliMouse, Logitech
Pilot Mouse+, Logitech MouseMan+, Genius NetMouse and Genius NetMouse Pro.)
For the integrated LINDY Extender ports you will need:
An LINDY Junior Extender or LINDY Pro Extender receiver. These receivers are
not provided with the LINDY Dual/Quad PRO and may be purchased separately.
The LINDY transmitter unit is built in to the LINDY Dual/Quad PRO.
A suitable twisted pair cable that runs from the LINDY Dual/Quad PRO to the
location where you wish to locate your remote keyboard, video monitor and mouse.
The LINDY Dual/Quad PRO built-in extender uses the same type of cable that is
commonly used for Ethernet networks. This type of wiring is often installed into
buildings and terminated at wiring sockets in various locations. If you have this type
of wiring then you will just need to run a standard network-style patch cable between
the wiring socket and the LINDY Dual/Quad PRO at one end and between the wiring
socket and the LINDY extender at the other end.
IMPORTANT WARNING
Do not connect the CPU Switch's extender ports to an Ethernet hub or other
digital network device. The s ignals carried on the twis ted pair cable between
the CPU Switch and the Lindy Extender are ANALOGUE. Plugging the CPU
Switch or Lindy Extender into a digital network device s uch as a hub may
damage you devices
LINDY Dual/Quad PRO
Installation and Use

Use of PS/2 and RS232 style mice with the LINDY Dual/Quad PRO - All of the
mouse connections from LINDY Dual/Quad PRO to PCs support either a PS/2 or an
RS232 mouse. LINDY Dual/Quad PRO automatically converts from the PS/2 mouse
commands to RS232 serial mouse commands. Serial mice types are selected by
using an adapter as described in Appendix A. The LINDY Dual/Quad PRO will
operate without a mouse connected if you do not wish to use one.
2.2 Mounting the LINDY Dual/Quad PRO
The LINDY Dual/Quad PRO has been designed to be used either on a desktop or
mounted in a 19 inch rack. If the LINDY Dual/Quad PRO is to be used on a desktop
then you will need to stick the supplied self-adhesive rubber feet to the underside of
the LINDY Dual/Quad PRO. If the LINDY Dual/Quad PRO is to be mounted in a 19
inch rack then you will need to fit the rack mounting brackets to the side of the
LINDY Dual/Quad PRO. Do this using the brackets and screws provided.
2.3 Connecting your devices
Ensure that the power is disconnected from the LINDY Dual/Quad PRO and all
devices which are to be attached. Connect any local keyboards, monitors and mice
to the user port connectors at the rear of the LINDY Dual/Quad PRO (see figure 2).
The user ports are coloured white and the individual connectors are colour coded
for your convenience. If you are connecting several KVM (Keyboard, Video monitor,
Mouse) sets then you do not need to use the same brands or mix of devices on each
user port.
User ports 1 and 3 are dual access ports and may have both a local KVM
(connected directly) and a remote KVM (connected via and LINDY extender)
attached at the same time. The local and remote KVM’s share the port on a timeout
basis but only one KVM may be using the port at any one time. If you are not using
all the local KVM connections it is preferable to connect the KVM’s to ports that are
not shared with the LINDY so that these KVM’s have fully independent access to the
LINDY Dual/Quad PRO.
Next connect each computer system unit in turn with the keyboard cable, mouse
cable and video cable. LINDY 3-in-1 keyboard/video/mouse cables are
recommended for maximum convenience and video quality. Remember that the
video quality is maximised if the cables are kept as short as possible. Where
LINDY Dual/Quad PRO
Installation and Use

Download from Www.Somanuals.com. All Manuals Search And Download.
possible, 2 metre cables are recommended as these will give very high video
quality. Any unused computer connections can be left unconnected. To connect
computers with serial mouse connections and AT style keyboard connections use
the adapters specified in appendix A. If you have an existing 6-pin mini-DIN to 9-pin
serial adapter that came with a mouse it may not be suitable for use with the LINDY
Dual/Quad PRO as the are several different standard wiring configurations for these
adapters.
The LINDY Dual/Quad PRO is now ready for connection to the mains using the
mains power adapter supplied. It is important to apply power to the LINDY
Dual/Quad PRO first, then power on the monitor and each of the computers in turn.
Failure to switch the LINDY Dual/Quad PRO and computers on in the correct order
can lead to the mouse and/or keyboard not being recognised by the computers
when they are switched on.
You may attach the power adapter to either power inlet A or power inlet B (see
figure 2). These ports are both the same and are provided to enable you to connect
a redundant (spare) power supply (see section 4.2 for more details). Connect your
power adapter to either of the power inlet ports to power on the LINDY Dual/Quad
PRO. There is no ON/OFF switch and the LINDY Dual/Quad PRO will start to
operate as soon as the power is applied.
2.4 Configuring your PCs
Configure your PC in the same way that you would if your keyboard, mouse and
monitor were all connected directly to your PC, but bearing in mind the following
point:
LINDY Dual/Quad PRO emulates Microsoft compatible serial, IntelliMouse and
LINDY Dual/Quad PRO
Installation and Use

PS/2 mice, so ensure that your PC software is configured for a Microsoft mouse of
the correct type. Refer to the list of supported drivers in section 2.1.
2.5 Structuring your LINDY Dual/Quad PRO installation
A single LINDY Dual/Quad PRO 16 may be used to manage and control up to 16
computers (see figure 5). For larger numbers of computers, Dual/Quad PRO units
may be cascaded in a tree structure to form a video switching network (see figure 6).
The LINDY Dual/Quad PRO unit at the top of this tree structure is normally used to
control all the cascaded LINDY Dual/Quad PRO’s although other configurations are
possible.
The LINDY Dual/Quad PRO is fitted with an intelligent communication system that
enables it to detect and communicate with other LINDY Dual/Quad PRO’s so that it
is able to positively verify that all the cascaded LINDY Dual/Quad PRO’s have
correctly responded to a switching request from the user. The LINDY Dual/Quad
PRO’s communicate with each other via the keyboard cables.
LINDY Dual/Quad PRO may be cascaded in a very flexible manner. Either 1, 2, 3 or
4 links may be made between cascaded LINDY Dual/Quad PRO’s. The number of
independent users supported by the system is determined by the number of
cascade links that have been installed. If only two cascade links are made then only
two users have simultaneous access to ports on the cascaded LINDY Dual/Quad
PRO’s. The LINDY Dual/Quad PRO intelligently manages the cascade links and
allocates them on a first come first served basis rather like a telephone network.
LINDY Dual/Quad PRO may also be cascaded to single user LINDY Dual/Quad
PRO products with the restriction that the LINDY Dual/Quad PRO units must be on
the last layer of the tree and that no further units are cascaded off these.
When cascading LINDY Dual/Quad PRO keep in mind the following rules
The maximum number of layers in a LINDY Dual/Quad PRO cascade is four.
You may cascade 4 units with 1, 2, 3 or 4 KVM links and 2 units with 1 or 2 KVM
links. The number of KVM links that you install defines the number of simultaneous
uses that are supported.
Keep all cascade cables as short as possible. The video quality is maximised by
using the shortest possible total cable run from computer to KVM.
LINDY Dual/Quad PRO
Installation and Use
Page 17
Download from Www.Somanuals.com. All Manuals Search And Download.
If you are making multiple cascade links between LINDY Dual/Quad PRO then
ensure that the cables are approximately the same length.
LINDY Dual/Quad PRO devices may be cascaded to cascades but the Pro units
must always be on the lowest level of the cascade (in other words you must not
cascade an device off a Pro device)
LINDY Dual/Quad PRO 4, 8, 12 and 16 models may be cascaded together.
You must choose groups of cascade ports from the following table. When you
cascade using a group of ports the system will allocate the first available free port in
that group (see section 4.10 and 4.16 for more details)

2.6 Maximising the video quality
The LINDY Dual/Quad PRO supports very high bandwidth video signals and
resolutions up to 1900 x 1440 pixels. It regenerates the video signals using wide
band amplifiers in order to minimise any loss of video quality. All video cables
introduce distortion onto the video signal. For short cables this is minimal but for
longer cables the loss of quality can start to become noticeable particularly at higher
video resolutions. To maximise the video quality of your LINDY Dual/Quad PRO
installation we recommend the following:
Use the shortest possible video cables between your devices. High quality two
metre long cables such as the LINDY 3-in-1 combination cable will give excellent
results.
Avoid using cables with 15-pin D-type connectors that are not specifically
designed to carry video signals - you will see a picture but the quality will be truly
appalling with smudging, ghosting and loss of focus. Cables that are designed to
carry video signals are constructed using three separate co-axial cores to carry the
red, green and blue signals. These co-axial cores make the cable thick like the
cable that you see coming out of the back of a monitor. Typically this cable will be
8.5 to 9 mm in diameter. If your cable is thin (say 6mm in diameter) or does not look
like the cable you would expect to see coming out of a monitor then it may well be
an unsuitable 'data' cable. Such cables are only suitable for very low resolution
DOS-style screens.
Where possible use a single cable of the correct length rather than multiple
extension cables. If you must use an extension cable then make sure that it is a
cable that is specifically designed to carry video signals.
When cascading LINDY Dual/Quad PRO’s use the shortest possible cables
between units. Structure the installation so that the maximum cable run between
computers and KVM’s is minimised. If possible keep this distance to below 30
metres (100 feet).
For longer distances use the LINDY extender.

2.7 Other useful installation information
PC boot up sequence - When your PCs are powered on they communicate with
any attached keyboards and mice and setup parameters required by the particular
operating system. It is necessary for the LINDY Dual/Quad PRO to be attached and
powered on during this sequence so that it can give the required responses and
keep track of all the modes and settings requested by each of the connected PCs.
Mouse characteristics - do not unplug a PS/2 mouse connection from a PC whilst
the PC is on. Due to the design of PS/2 mice communications the mouse function on
the PC will be lost and you will have to re-boot the PC to regain normal operation.
Unplugging the mouse from the LINDY Dual/Quad PRO will also cause it to stop
operating when it is plugged back in. RS232 mice can usually be unplugged and
plugged back in provided that a mouse was connected when the operating system
initially booted. The LINDY Dual/Quad PRO is fitted with a PS/2 mouse recovery
system which allows you to disconnect and re-connect the shared mouse without
powering down the system (although this is generally not advisable) - see section
2.8 for details.
Keyboard and mouse mode switching - The LINDY Dual/Quad PRO keeps a log
of the keyboard and mouse mode and resolution settings requested by each of the
connected PCs. These settings are automatically restored to the shared keyboard
and mouse when the LINDY Dual/Quad PRO channel is switched thus ensuring
maximum software compatibility. The keyboard num, caps and scroll lock states are
an obvious example of this process.
2.8 Re-enabling a disconnected PS/2 mouse
If you disconnect the shared PS/2 mouse from the LINDY Dual/Quad PRO by
accident during operation then the mouse operation will be lost when the mouse is
plugged back in. To avoid having to reboot the entire system in this situation the
LINDY Dual/Quad PRO is fitted with an automatic mouse recovery system.
With the PS/2 mouse disconnected, change the channel using the keypad or
keyboard hotkeys. The LINDY Dual/Quad PRO detects that the mouse has been
disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse
and the LINDY Dual/Quad PRO will re-initialise it.

Alternatively you can reset the keyboard and mouse for a given user port by using
the LINDY Dual/Quad PRO's keyboard and mouse reset function (see section 4.17).
This function only resets the keyboard and mouse attached to the selected user
port. It does not affect the status of any of the LINDY Dual/Quad PRO's other ports
or the CPU connections.
2.9 Hot plugging the LINDY Dual/Quad PRO into running systems
and re-enabling disconnected CPU PS/2 mouse connections
It is advisable to switch off the systems that are going to be connected to the LINDY
Dual/Quad PRO before installation. However if this is not possible then most
systems can be hot plugged by using the LINDY Dual/Quad PRO’s mouse
restoration functions. The keyboard connection will normally restore itself
automatically.
On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and
plugged back in whilst the PC is running. Mouse movement can then only be
restored by rebooting the PC. This is because the mouse drivers only setup and
enable the mouse when the PC is initially booted.
If you have switched off your LINDY Dual/Quad PRO or you are attempting to ‘hot
plug’ it into a system that is already running, you may be able to restore lost mouse
movement using the LINDY Dual/Quad PRO's mouse restoration functions.
Mouse restoration functions should be used with care as unpredictable results
may occur if the wrong mouse type is selected. If in doubt restore the mouse
by powering down the PC normally.
Standard PS/2 mouse data uses a different data format to IntelliMouse data and so
two reset functions are provided on the LINDY Dual/Quad PRO. The type of data
format expected by the PC depends upon the driver and the type of mouse that was
connected when the driver was booted. The following table may be used as a guide.
Note that the mouse reset functions predict the likely mouse resolution settings but
may not restore the speed or sensitivity of the mouse exactly as they were when the
PC originally booted.

3. Configuring the LINDY Dual/Quad PRO
3.1 Configuration summary
The LINDY Dual/Quad PRO is configured using the on-screen menu system which
is activated by default when you first power on the system. It may also be accessed
by using the keyboard 'hotkeys' (see section 4.8) or by using the LINDY Dual/Quad
PRO's front panel keys (see section 4.6). The following steps summarise a typical
configuration process. For more advanced information on each of the configuration
steps please refer to the appropriate sections of this manual shown in brackets.
Note: The LINDY Dual/Quad PRO is configured via the ADMIN user account. The
LINDY Dual/Quad PRO will allow multiple users to be logged in under the ADMIN
account but will only allow one of these users to be adding or editing computer
names or user profiles or setting global and setup options at any one time.
Step 1 - Decide if you are going to use password security
The LINDY Dual/Quad PRO may be run with security enabled or disabled. With
security disabled, all user ports have full access to all of the computers and full
administration rights. The LINDY Dual/Quad PRO is shipped to you with security
disabled. This mode is suitable for simple installations with a small number of users.
Larger installations or systems with larger numbers of users will require password
security to be enabled. In this mode, each user logs on to the system and is
allocated access rights to defined computers by the system administrator. This
mode is recommended for most systems (see section 3.2 for details on how to
enable security). If you are not using security the go to step 4.
Step 2 - Create an ADMIN (administration) account password
The LINDY Dual/Quad PRO has a fixed user account that cannot be deleted named
ADMIN. This user account is the only one that is able to make important system
changes. If you are going to be using security then you should allocate a password
to this account (see section 3.3 for instructions).
LINDY Dual/Quad PRO
Installation and Use

Download from Www.Somanuals.com. All Manuals Search And Download.
Step 3 - Create user accounts
Login to the LINDY Dual/Quad PRO using the ADMIN account and add user profiles
and passwords for each of the system users (see section 3.4). The LINDY
Dual/Quad PRO supports up to 16 user profiles.
Step 4 - Add / edit names to identify your computers
Whilst you are logged into the LINDY Dual/Quad PRO using the ADMIN account,
create names for each of the computers that you have attached to the system. The
LINDY Dual/Quad PRO creates default names for each of its ports (Computer 1 to
Computer 16). These default names may be edited as required. Whilst adding the
computer names you can define which users will have access to each computer.
Each computer has an associated 8 digit port number which defines its location. If
you are using a single LINDY Dual/Quad PRO then all the computers will have two
digit port numbers (01 to 16). If you are cascading LINDY Dual/Quad PRO’s then
each computer will have a four, six or eight digit port number depending on the
number of cascade levels that have been connected (see section 4.10 for details).
The LINDY Dual/Quad PRO supports up to 512 computer names although special
versions are available that support more names.
Step 5 - Set the required SETUP OPTIONS and GLOBAL PREFERENCES
Use the ADMIN account to select the required SETUP OPTIONS and GLOBAL
PREFERENCES. The SETUP OPTIONS menu is used to configure important
system operating parameters such as security mode, language, hotkeys and control
options. The GLOBAL PREFERENCES menu is used to select various timing
characteristics and other options.
3.2 Enabling password security
The LINDY Dual/Quad PRO may be operated with or without security enabled. With
no security all users will have full administration rights and full access to all the
connected computers. For systems with several users this may not be desirable.
System security is enabled using the on-screen menu. The on-screen menu is
activated automatically when you first switch on the LINDY Dual/Quad PRO but may
also be selected using the keyboard hotkeys (see section 4.8) or the front panel
controls (see section 4.6).

To switch on the password security system:
From the main on-screen menu press F1 for MORE MENUS.
Select SETUP OPTIONS from the menu.
Move the menu bar over the SECURITY option.
Press SPACE BAR to enable security.
Press ESC to quit from the menu.
3.3 Setting an ADMIN password
The LINDY Dual/Quad PRO supports up to 16 user profiles. The administrator of the
system can grant or deny users access to any of the connected computers and has
complete control over the setup of the system. The administrator accesses the
system via a special user named ADMIN. This profile may not be altered or deleted
from the system and has full access rights to all computers and system parameters.
Consequently it is advisable to set a password for this user.
To set a password for the ADMIN user:
From the main on-screen menu press F1 for MORE MENUS.
Select EDIT USER LIST from the menu.
Move the menu bar over the ADMIN user.
Press RETURN or ENTER to edit the ADMIN user.
Press RETURN or ENTER again to edit the ADMIN user's password.
Make sure that the password you want is displayed.
Press RETURN or ENTER to save the password.
You will now see the "Edit Access Rights" menu. The ADMIN user always has
access to all the computers. Press RETURN or ENTER again to quit from this
menu.
3.4 Creating and editing user accounts
To create user accounts:
Ensure that you are logged on as the ADMIN user.
From the main on-screen menu press F1 for MORE MENUS.
Select EDIT USER LIST from the menu.
Press INSERT to add a new user.
Type in the name of the new user and press RETURN or ENTER.

Type in the password for the new user and press RETURN or ENTER.
(You may leave the password field blank if you do not want to define a password)
Define the computers that you want this user to have access to using the SPACE
BAR and function keys as directed on the menu. The user will have access to all
the starred (selected) computers. Don't worry if all the computers have not yet
been defined. You can allocate users access to computers when you add the
computer names later.
Press RETURN or ENTER to create the user.
Follow a similar process to edit users:
In the EDIT USER LIST use the menu bar to select the user that you want to edit.
Press ENTER or RETURN to edit the user's name, password and access rights.
Press RETURN or ENTER if you want to keep the existing entries.
3.5 Creating and editing computer names
Computer names provide a very convenient way of selecting and identifying
computers that are attached to the LINDY Dual/Quad PRO. You can select
computers by port number (see sections 4.8 and 4.16) but when you have several
computers it becomes hard to remember which computer is attached to which port.
By defining descriptive computer names you can select the required computer from
an on-screen menu without having to remember which physical port the computer is
connected to. For each computer name that you define you can grant or deny
access to any of the defined users.
Each computer name that you define will have an associated port number. This is
the LINDY Dual/Quad PRO port that the computer is attached to. If all of your
computers are connected to a single LINDY Dual/Quad PRO then all the port
numbers will be two characters long (for example: 01, 02, 03, 16 etc.). If you are
cascading LINDY Dual/Quad PRO then the port numbers will be four, six or eight
characters long depending upon whether you have two, three or four levels of
cascade (see figure 7). See the end of this section and section 4.10 for an
explanation of how the port numbers are constructed. The LINDY Dual/Quad PRO
supports up to 512 computer names.

To create computer names:
Ensure that you are logged on as the ADMIN user.
From the main on-screen menu press F1 for MORE MENUS.
Select EDIT COMPUTER LIST from the menu.
Press INSERT to add a new computer name.
Type in the name of the computer and press RETURN or ENTER.
Type in the port number for this computer and press RETURN or ENTER.
Define the users that you want user to have access to this computer the SPACE
BAR and function keys as directed on the menu. The starred users will have
access to this computer. Don't worry if all the users have not yet been defined.
You can allocate computers to users when you add the users later.
Press RETURN or ENTER to create the new computer name.
When you are adding computers it is advisable to setup just one name for any
particular port. Avoid creating two names for the same port as this can lead to
confusion. Also, if you are using ports to cascade to other LINDY Dual/Quad PRO’s,
avoid setting up unique names for individual ports that form part of a group of ports
that are being used to cascade. For example, if you are using group 41 (ports 1,2,3
and 4) to cascade to another LINDY Dual/Quad PRO then avoid setting up
individual names for these ports.
Follow a similar process to edit computer names:
In the EDIT COMPUTER LIST use the menu bar to select the computer that you
want to edit. Press ENTER or RETURN to edit the computer's name or change the
users who you want to have access to this computer. Press RETURN or ENTER if
you want to keep the existing entries.
Creating entries for computers connected to cascaded LINDY Dual/Quad
PRO’s
You can cascade LINDY Dual/Quad PRO 4 units using one, two, three or four KVM
links and LINDY Dual/Quad PRO 2 units using one or two KVM links. Section 2.5
explains the rules that you must follow when installing a LINDY Dual/Quad PRO
cascade. The number of cascade links that you install determines the number of
simultaneous users that can access computers on the cascaded LINDY Dual/Quad
PRO’s. Ideally if you are cascading 4 units then you should use four cascade links
as this will cause no blocking and will allow all four users simultaneous access to all
computers.
LINDY Dual/Quad PRO
Installation and Use

Each computer name that you add to the on-screen menu has an associated port
number that tells the LINDY Dual/Quad PRO where to find the computer. Port
numbers for computers attached to a single LINDY Dual/Quad PRO are simply the
port number that the computer is attached to. Port numbers for computers
connected to cascaded LINDY Dual/Quad PRO’s are constructed by defining the
port routing that is required to get from the user's KVM to the computer.
Figure 7 illustrates how port numbers are constructed and how the physical
configuration of a cascaded system relates to entries in the on-screen menu. The
illustrated configuration is an unlikely configuration in practice but has been chosen
for explanation purposes. If you make multiple cascade links then they must be
connected to the groups of ports defined in figure 8. These ports have associated
group port numbers. The LINDY Dual/Quad PRO uses this group port number to
connect to the first available port in that group. For example, group port number 21
comprises of ports 1 and 2. If these ports are linked to a cascaded LINDY
Dual/Quad PRO and users try to connect to computers that are attached to the
cascaded LINDY Dual/Quad PRO, the system will allocate the cascade links to the
first two users on a first come first served basis. Further users that try to connect to
computers on the cascaded LINDY Dual/Quad PRO will get a message saying that
no cascade links are available and they will not be able to connect to the cascaded
LINDY Dual/Quad PRO until one of the previous users has finished with one of the
cascade links.

3.6 Setting the SETUP OPTIONS and GLOBAL PREFERENCES
The SETUP OPTIONS and GLOBAL PREFERENCES are system operating
parameters that apply to the whole system rather than to individual users. These
may only be setup or changed by the system administrator logged in using the
ADMIN account. From the main menu press F1 for MORE MENUS. Use the cursor
keys to position the menu bar over SETUP OPTIONS or GLOBAL PREFERENCES.
Press ENTER or RETURN to view the individual menus. Use the cursor keys to
place the menu bar over the required option and then use SPACE BAR to change
the option as required. Press ESC to quit and save the changes.

3.6.1 SECURITY
Accessed from menu: SETUP OPTIONS
Settings: DISABLED, ENABLED
With security disabled there is no requirement for users to login to the system. All
users have full access to all the connected computers and full administration rights.
With security enabled, users are required to login to the LINDY Dual/Quad PRO.
Each user is allocated access rights to computers by the system administrator and
they are only able to see the computers that they have access to on their on-screen
menu.
3.6.2 LANGUAGE
Accessed from menu: SETUP OPTIONS
Settings: ENGLISH, FRENCH, GERMAN
This option specifies the language that is used for the on-screen menu and the
keyboard layout that is assumed for the keyboard. When the French option is
selected the keyboard is assumed to have an AZERTY format. When the English
and German options are selected the keyboard is assumed to have a QWERTY
format. The new language settings are enabled when you quit from the SETUP
OPTIONS menu. The language option only affects the way that the CPU Switch
interprets the keyboard keys, it does not affect the way that the computers interpret
the keyboard. It is advisable to avoid setting a language that you do not understand
as all the menus will change to use the new language and you may have difficulty
reselecting your original language.
3.6.3 HOTKEYS
Accessed from menu: SETUP OPTIONS
Settings: CRTL+ALT, CTRL+SHIFT, ALT+SHIFT, ALT GR, LEFT ALT+RIGHT ALT,
LEFT CTRL+LEFT ALT, RIGHT CTRL+RIGHT ALT, DISABLED
The keyboard hotkeys are special combinations of keys that, when used together
with certain keyboard "command keys", perform special LINDY Dual/Quad PRO
functions. For example, pressing the hotkeys together with the "M" key will cause
the on-screen menu to be displayed on your monitor. Other hotkey combinations
allow you to query which computer you are connected to and to move the on-screen
menu around the screen. You can also use the hotkeys together with the port

number to quickly select a chosen computer without activating the on-screen menu.
See section 4.8 for full details on using keyboard hotkeys to control the LINDY
Dual/Quad PRO. We do not normally recommend that you disable the hotkeys but if
you choose to do this then you will need to access the on-screen menu using the
LINDY Dual/Quad PRO's front panel controls.
3.6.4 KEYPAD CONTROLS
Accessed from menu: SETUP OPTIONS
Settings: ENABLED, DISABLED
The key controls on the front of the LINDY Dual/Quad PRO may be disabled so that
it is only possible to select the special channels "o" and "0" (the on-screen menu
and the non-existent channel zero).
3.6.5 EXCLUSIVE USE
Accessed from menu: SETUP OPTIONS
Settings: ALLOWED, DISABLED
In normal operation, the LINDY Dual/Quad PRO will allow two or more users to
share access to a computer. In this mode, the computer's video picture will be
displayed on all the user's monitors but only one user may have active control of the
computer's keyboard and mouse at any one time. The LINDY Dual/Quad PRO
detects an active user by looking for keyboard and mouse data. A user becomes
inactive if no keyboard or mouse data has been received by the LINDY Dual/Quad
PRO for a specified timeout period. Whilst one user is active all the other users that
are connected to the same computer will see a "video only" message displayed on
their screen.
There may be situations where particular users want to be able to control and view
their computers in private with exclusive use. The LINDY Dual/Quad PRO has the
facility to allow users to select exclusive use of computers but this facility should be
used with care. When exclusive use is requested the video from the selected
computer is only available to the user with exclusive access. Users that have
selected exclusive access are never timed out by the LINDY Dual/Quad PRO and so
all other users are effectively "locked out" until the exclusive user switches to
another computer or logs out. This could potentially be very irritating if a user has
selected exclusive use and has then left their desk without logging out. This would
prevent other users from working on the computer until they came back.

Consequently the system administrator can disable all exclusive use so that all
connections are shared.
3.6.6 AUTOMATIC LOGOUT
Accessed from menu: SETUP OPTIONS
Settings: DISABLED, ENABLED
The CPU Switch enables you to restrict access to your computers on a login basis.
If a user forgets to logout when they have finished accessing the CPU Switch then
the user console may unintentionally be left with full access to all the computers.
The CPU Switch may be set to automatically logout unattended user consoles when
the screen saver kicks in. This reduces the risk of security problems by preventing
user consoles remaining in a permanent “logged-in” state when there is no keyboard
or mouse activity. The automatic logout feature is only enabled when the screen
saver feature is active (i.e. not disabled).
3.6.7 MOUSE SWITCHING
Accessed from menu: GLOBAL PREFERENCES
Settings: ENABLED, DISABLED
Like most LINDY Electronics Ltd KVM switches, the LINDY Dual/Quad PRO channel
may be switched using a three button mouse or IntelliMouse (see section 4.9).
Pressing the central button or wheel button together with the left hand mouse button
will cause the LINDY Dual/Quad PRO to switch to the next available computer.
When mouse switching is enabled the central mouse button or wheel mouse button
is allocated to control the LINDY Dual/Quad PRO and is not therefore available for
use by computer applications. If you want to use the central mouse button within
your applications you will need to disable mouse switching. The rotation action of an
IntelliMouse wheel is not affected and is always available to the PC application.
3.6.8 SCREEN SAVER
Accessed from menu: GLOBAL PREFERENCES
Settings: DISABLED; 2, 5, 7, 10,15, 20 & 30 MINUTES
To avoid burning out the phosphor on CRT monitor screens, the LINDY Dual/Quad
PRO can be set to blank the screen after no keyboard or mouse activity has been
detected for a selected timeout period. If preferred, the user can blank the screen
manually by selecting channel '0' using the keyboard hotkeys or by pressing ESC
from the login screen.

3.6.9 AUTOSCAN MODE
Accessed from menu: GLOBAL PREFERENCES
Settings: ACTIVE, ALL
The LINDY Dual/Quad PRO supports an autoscan mode that automatically scans
between the connected computers in sequence. The LINDY Dual/Quad PRO can be
set to scan ALL the available computers or just the available computers that are
currently powered on (the ACTIVE computers). Scanning just the active computers
avoids blank screens from being displayed and stops the monitor from going into a
power down state on every scan cycle.
WARNING - Many modern monitors are fitted with automatic power save relays
and will switch off after a few seconds if connected to an inactive PC. If you
are using such a monitor you must not set the LINDY Dual/Quad PRO to scan
ALL ports. Constant switching on and off of your monitor's relay will
eventually damage your monitor.
3.6.10 AUTOSCAN TIME
Accessed from menu: GLOBAL PREFERENCES
Settings: DISABLED; 2, 5, 7, 10, 15, 20, 30 SECONDS
The autoscan time defines the length of time that the LINDY Dual/Quad PRO will
display video from an autoscanned computer before changing to the next computer.
If the DISABLED setting is chosen then no autoscan functions will be available.
3.6.11 OSD DWELL TIME
Accessed from menu: GLOBAL PREFERENCES
Settings: 1, 2, 3, 5, 10 SECONDS
After a successful computer channel change the LINDY Dual/Quad PRO will display
a confirmation message for a few seconds. The length of time that this confirmation
message dwells on the screen may be changed. Options are 1, 2, 3, 5 and 10
seconds.

3.6.12 USER TIMEOUT
Accessed from menu: GLOBAL PREFERENCES
Settings: 2, 5, 10, 30 SECONDS; 1, 5, 10 MINUTES
When two users are connected to the same computer only one can have access at
any one time. When no keyboard or mouse data has been received from the active
user port for the user timeout period the LINDY Dual/Quad PRO will allow other
users to access the computer. The new port then becomes the active port until it too
times out. To avoid confusion between users it is desirable to set the timeout period
to be sufficiently long so that user's work is not needlessly interrupted by other users
and sufficiently short to ensure good overall system efficiency. The user timeout
value also controls the timeout between the local and remote access points on user
ports 1 and 3.
3.6.13 RS232 Mouse Type
Accessed from menu: GLOBAL PREFERENCES
Settings: INTELLIMOUSE, 2 BUTTON, 3 BUTTON
These setting control the type of RS232 mouse that the LINDY Dual/Quad PRO
reports to computers. All the necessary conversions are dealt with automatically with
the LINDY Dual/Quad PRO. The IntelliMouse setting sends four byte mouse reports
to the computers and is therefore very slightly more sluggish than the others that
send three byte mouse reports. RS232 mice are almost always more sluggish than
PS/2 types because the data rate is much slower.

4. Using the LINDY Dual/Quad PRO
This section explains the general operation of the LINDY Dual/Quad PRO. We
recommend that you read this section before starting to use the product.
4.1 Rear panel special function switches
Before powering on the LINDY Dual/Quad PRO ensure that the two option switches
on the rear are set to the OFF (up) position. Option switch 1 is reserved for future
use and option switch 2 is used to enable firmware upgrades (see section 5).
4.2 Power supply connections and indicators
The LINDY Dual/Quad PRO is fitted with two power inlets that are labelled A and B
(see figure 2). These power inlets are both the same and either inlet may be used to
power the LINDY Dual/Quad PRO. The LINDY Dual/Quad PRO is shipped with a
single power adapter but you may optionally purchase a second power adapter to
provide power supply redundancy (part code PSU-IEC-5VDC). Plug the power
adapter into one of the inlets. The power indicators on the front of the LINDY
Dual/Quad PRO (see figure 1) monitor the voltage that is being supplied to each
power inlet. If the power indicators A or B are illuminated then a healthy power
adapter is connected. If you have two healthy power adapters connected then you
may disconnect and reconnect one of then without disturbing the operation of the
LINDY Dual/Quad PRO.
4.3 USER display and key switch
The USER key selects the user port that is shown on the green USER display (see
figure 1). Pressing the key will cause the green display to change to the next user
port in numerical sequence. When the USER display is changed, the red
COMPUTER display will also change to show the current connection status of the
new user port. LINDY Dual/Quad PRO 4 models have 4 user ports and LINDY
Dual/Quad PRO 2 models have 2 user ports.

4.4 COMPUTER display and key switch
The COMPUTER key selects the computer port that is to be connected to the user
port that is currently displayed on the green USER display (see figure 1). Pressing
the key will cause the red COMPUTER display to change to the next available
computer port in numerical sequence. The next available computer port is defined
by the way that the LINDY Dual/Quad PRO is configured.
There are two special computer ports that may be selected using the COMPUTER
key switch. These are the on-screen menu port 'o' and the non-existent channel
zero '0'. Selecting the on-screen menu port will cause the on-screen menu or the
login menu to be displayed. Selecting channel zero will cause the video to be
disabled and all keyboard and mouse activity to have no effect upon any of the
connected computers. These channels are provided as convenient places to 'park'
user ports that are not currently in operation.

4.5 Activity indicators
The LINDY Dual/Quad PRO has a front panel activity indicator for each user port
(see figure 1). The indicator will flash when keyboard or mouse data is received by
the LINDY Dual/Quad PRO. These indicators provide a useful confirmation that the
keyboards and mice connected to the LINDY Dual/Quad PRO are functioning
normally.
4.6 Selecting a computer using the front panel controls
To select a computer using the front panel controls, press the USER key until the
green USER display shows the user port number that your keyboard and mouse are
connected to. Then press the COMPUTER key until the red COMPUTER display
shows the computer that you wish to connect to. Pressing the computer key will
cause the computer channel to change to the next available port. If the password
security system has not been enabled then this will be the next highest channel
number in the sequence shown below. If password security has been enabled then
you will only be able to select the computer ports that you have access to. If the
front panel controls have been disabled by the administrator then you will only be
able to select the special channels 'o' and '0' (the on-screen menu / login screen or
non-existent channel zero).

If password security has been set on the system then the following login menu will
appear when the LINDY Dual/Quad PRO is switched on or when no user is currently
logged in. The previous user may have activated the screen save function (screen
blanking). If so, you may need to press a key before the login menu appears. Type
in you user name and password to access the LINDY Dual/Quad PRO.

4.8 Keyboard hotkeys
LINDY Dual/Quad PRO can be conveniently controlled using special keyboard
hotkey combinations. These hotkey combinations can be used to select computers
and perform a number of other useful functions. All of the hotkey control commands
are invoked by holding down the hotkeys and then pressing a command key. By
default, the two hotkeys are ‘CTRL’ and ‘ALT’, although other combinations can be
selected by reconfiguring the hotkeys (see section 3.6.3). Once the hotkey
command has been activated you will need to release the hotkeys and the command
key before a new hotkey command is accepted by the LINDY Dual/Quad PRO.
HOTKEYs + TAB is an exception and this allows you to 'tab through' the ports by
holding down the hotkeys and repeatedly pressing TAB. HOTKEYs + the cursor
keys is also an exception. You can hold down the hotkeys and repeatedly press the
cursor keys to change the position of the on-screen menu.
The hotkey commands are summarised below (note that the numbers on the
numeric keypad do not form part of a valid hotkey). The hotkeys will only select the
requested channels if you have access rights to the requested channel.
Selecting computers using the hotkeys and the port number is most suitable for
systems with small numbers of computers. For systems with more computers it is
easier to use the on-screen menu for computer selection.

4.9 Selecting computers using the mouse
Computers may conveniently be selected using a three button mouse. In order to
switch to the next computer simply hold down the central mouse button (the wheel
mouse button on an IntelliMouse) and click on the left hand mouse button to select
the next computer. If password security has been set then the LINDY Dual/Quad
PRO will select the next available channel, otherwise it will select the next numerical
channel. Mouse switching may be enabled or disabled (see section 3.6.7). When
mouse switching is disabled the third button or wheel button state is ‘passed
through’ the LINDY Dual/Quad PRO and seen by the application software.
Selecting computers using the mouse is most suitable for systems with small
numbers of computers. For systems with more computers it is easier to use the on-
screen menu for computer selection.

4.10 Selecting computers using the on-screen menu
You can conveniently select computers by name using the LINDY Dual/Quad PRO's
on-screen menu. For systems with many computers this is the recommended
method of computer selection. The on-screen menu is called up by pressing the
‘HOTKEYs’ and the ‘M’ key together. Its position on the screen may be moved using
the 'HOTKEYs' and the cursor keys (see section 4.8)
For example, with the default hotkeys (CTRL + ALT) the key combination to launch
the on-screen menu would be:
press baM Mba

4.11 The reminder banner
Normally the LINDY Dual/Quad PRO will display a discreet computer name
reminder banner that reminds you which computer you are connected to. This
banner will normally appear at the top of the screen in a central location and may
optionally be disabled (see section 4.12.2). Many computer screens can look very
similar and so this banner serves as a useful reminder of which computer you are
working on. The colour and transparency of the banner can be selected to make it
as discreet as possible. It may also be moved around the screen in any direction by
using the ‘HOTKEYs’ together with the cursor keys.
For example to move the banner up the screen (assuming the default CTRL + ALT
hotkeys) use:
baw
The computer name banner is also used to tell the you that another user is using the
computer that you are currently connected to. Whist the other user has control of the
computer you will see the message "Video Only" below the computer name banner.

4.13 Using the FUNCTIONS menu
The FUNCTIONS menu provides you with a number of useful functions that will help
you to make the most of your LINDY Dual/Quad PRO. You can access the
FUNCTIONS menu from the main on-screen menu by pressing F1 and selecting
FUNCTIONS.
Standard users will be offered just two functions:
RESTORE STANDARD MOUSE and
RESTORE INTELLIMOUSE
If you have disconnected a mouse cable or you have switched the LINDY
Dual/Quad PRO off then the mouse connection will normally be lost. To reconstitute
the mouse connection use the mouse reset functions. See section 2.9 for a full
explanation of how these functions work.
The ADMIN user is also given the option to RESET TO FACTORY DEFAULTS.
This will clear all the computer and user names and set all parameters back to the

factory defaults. To avoid activating this function by accident the administrator must
confirm the reset instruction by pressing F8.
4.14 Querying the routing status
It is sometimes useful to know which KVM consoles are connected to which
computers and their connection modes (shared, exclusive or video only). For
example, if the CPU Switch denies you access to a particular computer you may
wish to know if another KVM console has exclusive use of this computer and
consequently is preventing your access. To query the routing status press F1 from
the main on-screen menu and then select ROUTING STATUS. A routing status
display similar to the one shown below will be displayed for 10 seconds. Press ESC
to quit or wait for the routing status screen to disappear.

4.15 Using the dual access ports (1 and 3)
The LINDY Dual/Quad PRO 2 is fitted with one dual access port and the LINDY
Dual/Quad PRO 4 is fitted with two dual access ports. These dual access ports have
connectors that enable a local KVM (Keyboard, Video monitor and Mouse) to be
attached and a connector that enables a remote LINDY Extender or LINDY Pro
Extender to be attached. Either the local KVM, connected directly to the LINDY
Dual/Quad PRO, or the remote KVM, connected to the LINDY extender, may be
used to access the LINDY Dual/Quad PRO. The video picture is duplicated on both
the local and remote access points but the LINDY Dual/Quad PRO will accept
keyboard and mouse data from only one KVM at a time. Whilst one of the KVM’s is
active, the num, caps and scroll lock keys on the inactive KVM's keyboard will flash
indicating that the KVM does not have control.
Once there has been no keyboard or mouse data from the active KVM for the
timeout period (see section 3.6.12 for instructions on how to set the timeout period),
the other KVM is allowed access. Once keyboard or mouse data activity is detected
from this new KVM it gains control and the other KVM is disabled.
4.16 Cascading LINDY Dual/Quad PRO’s
LINDY Dual/Quad PRO s can be cascaded in a tree structure to support larger
numbers of computers. Up to four cascade levels are supported and the number of
cascade links between LINDY Dual/Quad PRO’s can be chosen by the user. The
number of installed cascade links determines the number of users that may be
accessing ports on the cascaded units simultaneously. The full rules that must be
followed when configuring a cascade of LINDY Dual/Quad PRO’s are given in
section 2.5.

Although it is theoretically possible to select computers on cascaded units by
pressing the hotkeys and then typing in the port address this would be highly
confusing for users and is not generally recommended. Consequently it is normally
advisable to use the on-screen menu to select computers on cascaded units.
However it is sometimes useful to be able to connect to ports on cascaded units via
a specific cascade cable (rather than the first available of a group) in order to check
that the cabling is working as expected. To do this you can use a hotkey sequence
similar to the example shown below.
For example to connect to port 14 on a LINDY Dual/Quad PRO 4 that is cascaded
off port 1 of your first LINDY Dual/Quad PRO . Although the following example
selects a port with a four digit address (port 0114) you can type port addresses that
are eight digits long to access computers that are on the forth cascade level
(e.g. Port 01140203).

4.17 Resetting user port keyboards and mice
The LINDY Dual/Quad PRO gives you the facility to perform a complete power off
reset of the keyboard and mouse that are connected to a selected user port. This
can be useful if you wish to disconnect the keyboard or mouse and replace them
with alternatives. Keyboards will enable themselves automatically if they are
disconnected and then re-connected to the LINDY Dual/Quad PRO. Mice will not
normally re-enable themselves after they have been disconnected and re-connected
although they will do so automatically if the LINDY Dual/Quad PRO's channel has
been changed whilst the mouse is disconnected.
Consequently you will normally need to perform a power-off reset of the user port if
you have disconnected and re-connected a mouse. The power off reset function
only affects the selected user port and does not affect any of the computer
connections or any of the other user ports.
LINDY Dual/Quad PRO
Installation and Use

To perform a power-off reset for a selected user port:
1) Press the USER key on the front panel of the LINDY Dual/Quad PRO to select
the user port whose keyboard and mouse you wish to reset.
2) The selected user port number should now be shown on the green USER
display.
3) Press and hold down the USER key for 5 seconds until the green USER display
goes off. The keyboard and mouse will then be powered off.
4) As soon as the green display goes off you may release the USER key. The
green display will then come back on and a few seconds later the keyboard and
mouse will be powered on and ready for use.
4.18 Using the LINDY Junior / Pro Extender
Refer to the installation guide provided with your LINDY Extender. The transmitter
unit (LINDY Extender) is built into the LINDY Dual/Quad PRO so you will only need
the receiver (LINDY Junior Extender unit). You may use a LINDY Junior Extender
receiver or a LINDY Pro Extender receiver.
When using an LINDY extender we highly recommend that you set the LINDY
hotkeys to be different to the LINDY Dual/Quad PRO's hotkeys to avoid any
confusion
4.19 What to do if you forget your ADMIN password
If you forget your ADMIN account password you will not be able to access the
LINDY Dual/Quad PRO to add or edit users and computer names. If this unfortunate
situation does occur then you can resolve it by performing a complete reset to return
the LINDY Dual/Quad PRO to its factory default state. A complete reset erases all
the user names and computer names that you have setup. You can only perform a
complete reset if you have access to both the front and the rear of the LINDY
Dual/Quad PRO.

To perform a complete reset and return the LINDY Dual/Quad PRO to its factory
default state:
1) Power on the LINDY Dual/Quad PRO normally.
2) Whilst the LINDY Dual/Quad PRO is powered on move switch 2 on the rear
panel of the LINDY Dual/Quad PRO (labelled UPGRADE) to the ON (down)
position.
3) Press the USER and the COMPUTER keys together.
4) The green USER display will show 'r' for a few seconds to confirm that a reset is
taking place.
5) Return switch 2 to the normal OFF position (up).
4.20 Saving and restoring the menu configuration to and from an
Excel compatible file.
The CPU Switch will store up to 512 computer names and 16 sets of user access
rights. If you have a cascade of CPU Switches then it may take some time to enter
all the computer names and port numbers and decide on the access rights that you
are going to grant to each user profile. Consequently, for peace of mind it is useful
to be able to store these settings. This can be done by connecting a computer to the
CPU Switch’s RS232 serial port and uploading to configuration settings. You can
only perform this function if you are logged onto the CPU Switch as the ADMIN
user. The file that is used to store the configuration settings has the additional
advantage that it can be loaded into an Excel spreadsheet and edited to make
changes to computer names and access rights. This edited information may then be
downloaded back to the CPU Switch.
To save the menu names and configuration settings:
DQPREAD.EXE and DQPWRITE.EXE.
2. Connect the serial port on the rear of the CPU Switch to a serial COM port on
your computer using the serial cable supplied with the CPU Switch. If you have
lost this cable then you may use a replacement cable with a 9-way female
connector on one end and a 9-way male connector on the other end and all lines
connected straight through (i.e. pin 1 to pin 1, 2 to 2, 3 to 3 etc.).

3. Run the program DQPPREAD.EXE on the computer that is connected to the
CPU Switch’s serial port. Follow the instructions given by the program.
4. Make sure that you are logged onto the CPU Switch as the ADMIN user. From
the main selection screen press F1 for More Menus. In the Configuration Menu
select Functions. In the Functions menu select Send Data to RS232 port.
5. The CPU Switch should then send the configuration data to your computer. The
DQPREAD program will store the data in a file named DQPDATA.CSV that will
be created in the same directory that you ran the DQPREAD program from.
Please ensure that you have sufficient rights to write to this directory.
To edit the menu names and configuration settings:
You may open the DQPDATA.CSV using a spreadsheet program such as Microsoft
Excel. The format of a typical file is shown below. You will see that the computer
names (rows) are tabulated against the user profiles (columns). To grant a user
access to a computer, enter the value 1 in the box that is common to the computer’s
row and the user’s column. To deny access, leave this box blank. To add extra
users, add additional columns (up to 16 users). To add extra computers, add
additional rows (up to 512 computers). The ADMIN user will always be granted
access to all computers regardless of the values entered.

5. Upgrading the LINDY Dual/Quad PRO's
firmware
The LINDY Dual/Quad PRO uses flash memory technology which enables the
firmware code to be upgraded by the user. New keyboards, mice operating systems
and drivers are being launched all the time. From time to time the LINDY Dual/Quad
PRO's firmware will be updated to provide support for these new devices. You can
take advantage of these upgrades free of charge during the warranty period.
Upgrades are performed by connecting a PC's serial port to the LINDY Dual/Quad
PRO's serial port and running an upgrade program on the PC. This upgrade
program downloads the new firmware to the LINDY Dual/Quad PRO and checks that
the data has been programmed correctly.
You can check the version of the firmware that is currently loaded into your LINDY
Dual/Quad PRO using the on-screen menu. To do this activate the on-screen menu
using the keyboard hotkeys (see section 4.10) and then press F1. The version
number of the current firmware will then be displayed at the bottom of the
Configuration Menu.
To perform a firmware upgrade on your LINDY Dual/Quad PRO you will need a
suitable serial upgrade cable and an IBM PC compatible computer with an RS232
serial port and an operating system that supports DOS. Suitable upgrade cables
with 9-pin serial connectors are provided with the LINDY Dual/Quad PRO . If you
have lost your cable then you will need to buy a cable with a 9 way D type male
connector on one end and a 9 way D type female connector on the other end with all
9 lines connected "straight through" (i.e. pin 1 to pin 1, pin 2 to pin 2, pin 3 to pin 3
etc.). These are standard serial extension cables.
You will also need to obtain the latest version of the LINDY Dual/Quad PRO
you have your product serial number and model number at hand when requesting
an upgrade.
Note: The normal flash upgrade process does not clear the computer names, user
names, security passwords or other configuration settings.

To perform a flash upgrade on the LINDY Dual/Quad PRO :
Step 1 - Prepare your computers
Ensure that you have saved any important work on the connected computers. The
LINDY Dual/Quad PRO can be upgraded whilst attached to live systems but
remember that the mouse connections will probably need to be reconstituted after
the upgrade is finished (see sections 4.13 and 2.9). Where possible, mission critical
servers should be switched off or disconnected before performing an upgrade.
Step 2 - Connect your computer to the LINDY Dual/Quad PRO
Connect your computer's serial port to the LINDY Dual/Quad PRO 's serial port (see
figure 2). You do not need to set the serial baud rate and protocol because the
upgrade program will do this for you automatically (for reference, the RS232 baud
rate used by the upgrade program is 19200 and the protocol is 8 bits, 1 stopbit and
no parity).
Step 3 - Select flash upgrade mode using option switch 2 (labelled UPGRADE)
Move option switch 2 on the back of the LINDY Dual/Quad PRO to the ON position
(down).

Step 4 - Power off the LINDY Dual/Quad PRO
Remove both power supplies from the Dual / Quad PRO.
Step 5 - Power on the LINDY Dual/Quad PRO with the UPGRADE switch ON
Attach the power adapter to the LINDY Dual/Quad PRO whilst the UPGRADE switch
is ON. The green USER display should now show a lower case 'u'. This indicates
that the LINDY Dual/Quad PRO is ready to be upgraded.
The display should now show:
Step 6 - Run the upgrade program
The latest version of the LINDY Dual/Quad PRO firmware is available from the
supplied to you as a group and consist of several files as explained below. These
files should be downloaded to the same directory on your computer.
1) A universal upgrade program
LDQP.EXE
2) Binary code files for each of the processors within the LINDY Dual/Quad PRO
(up to 3)
e.g.
4X16A129.HEX
4X16B129.HEX
4X16C129.HEX
These files use the following naming scheme. The first four characters are the
model type (e.g. 4X16 is a LINDY Dual/Quad PRO 4 with 16 computer ports). The
fifth character is the processor designation. The last three characters represent the
firmware release version (e.g. 129 equals version 1.29).
LINDY Dual/Quad PRO
Installation and Use
Page 62
Download from Www.Somanuals.com. All Manuals Search And Download.
A data file that tells the upgrade program (LDQP.EXE) which binary code files (HEX
files) to download to the LINDY Dual/Quad PRO and where to put each file.
Theoretically this DAT file can be modified so that only certain processors are
upgraded but do not do this unless specifically instructed by LINDY technical
support.
e.g.
4X16V129.DAT
Like the hex files, the first three digits represent the model number (e.g. 2X8
represents a LINDY Dual/Quad PRO 2 with 8 computer ports). The next four digits
represent the version number (e.g. V129 equals firmware version 1.29).
To upgrade the LINDY Dual/Quad PRO, check that the DAT file designation
matches the model that you have. In other words, if you have a LINDY Dual/Quad
PRO 2 with 8 computer ports and you want to upgrade to version 1.30 then the DAT
file that you need would be named 2X8V130.DAT. Also check that all the required
files are loaded into the same directory on your computer. From that directory run
the upgrade file using the following command line.
LDQP {Dat_file_name}.DAT
Where {Dat_file_name} is the name of the required DAT file
For example, if the name of the required DAT file is 4X16V129.DAT then use the
following command line:
LDQP 4X16V129.DAT
IMPORTANT NOTE
The upgrade programs are DOS based to enable compatibility with the widest
range of operating systems. They run efficiently on DOS, Windows 3.X,
Workgroups, 95, 98, ME and Windows NT. The upgrades will take
approximately 10 minutes but vary slightly according to the CPU Switch model
and the speed of the PC. Upgrades run from PCs using Windows 2000 will take
very substantially longer due to the way that this operating system handles the
DOS programs. The upgrade will be reliable but may take around 3 hours to
complete!

Follow the instructions given on the screen to perform the upgrade. When the
upgrade is complete the program will confirm that the upgrade has been successful
and then quit.
Step 7 - Switch the UPGRADE key to the OFF position and cycle the power
Switch the UPGRADE switch on the rear of the LINDY Dual/Quad PRO to the OFF
position and disconnect the power. When the power is re-applied the LINDY
Dual/Quad PRO will operate using the new firmware.
Some useful issues to bear in mind when performing flash upgrades
The upgrade program rewrites the LINDY Dual/Quad PRO's firmware code. If the
upgrade process is interrupted then the LINDY Dual/Quad PRO will have invalid
code and will not be able to operate. It is therefore good practice to ensure that the
upgrade process is always fully completed. A partial or failed upgrade may be
rectified by performing another upgrade. If the upgrade process is interrupted
accidentally then you should immediately repeat the upgrade process without
moving switch 2 from the upgrade (ON) position. Switch 2 forces the LINDY
Dual/Quad PRO into flash upgrade mode and prevents the upgraded code from
being run. Running faulty or partially upgraded code may have unpredictable results
and may damage your LINDY Dual/Quad PRO or computing equipment. For obvious
reasons, the code that the LINDY Dual/Quad PRO uses to perform upgrades is not
itself upgradable - a common problem on some flash upgradable products that could
effectively be destroyed by a partial upgrade!
WARNING - Running faulty or partially upgraded code may have unpredictable
results and may damage your LINDY Dual/Quad PRO or computing equipment.

Appendix A. Cable and connector
specifications
IMPORTANT NOTE
The maximum cable lengths supported vary widely between devices and
cables. It may be possible to use cables that are longer than those specified
below with certain PCs and peripherals but this cannot be guaranteed. If you
experience problems try using shorter cables.
A1. Keyboard, monitor and mouse to LINDY Dual/Quad PRO
Cable specification:
All of the shared devices plug directly into the relevant ports at the rear of the LINDY
Dual/Quad PRO. If you use an AT style keyboard you will need an AT (5 pin DIN
female) to PS/2 (6 pin mini-DIN male) converter. Keyboard, monitor and mouse
extension cables can be used to increase the distance from LINDY Dual/Quad PRO
up to 10m. Most keyboards and mice will also operate at distances of 20 metres.
A2. LINDY to LINDY Dual/Quad PRO
Cable specification:
The LINDY uses standard 4-pair unshielded twisted pair cable of the same type that
is commonly used for Ethernet and other networks. Unshielded and shielded types
may be used at distances up to 200 metres.
IMPORTANT WARNING
Do not connect the LINDY Dual/Quad PRO's extender ports to an Ethernet hub
or other digital network device. The signals carried on the twisted pair cable
between the LINDY Dual/Quad PRO and the LINDY are ANALOGUE. Plugging
the LINDY Dual/Quad PRO or LINDY into a digital network device such as a
hub may damage you devices

A3. LINDY Dual/Quad PRO to PCs 1 to 16
Cable specifications:
Video - 15 pin high density male D connector to 15 pin high density male D
connector wired as a standard VGA PC to monitor cable. There are two types
commonly available. The best type of cables which will give excellent quality are
constructed with coaxial cable cores. Cheaper ‘data’ cables are often used, but can
degrade video quality if used over longer distances. Avoid using 'data' cables longer
than 2 metres unless the video quality is not important. Good quality coaxial video
cables may be run at distances up to 30 metres with acceptable video quality. In a
cascaded application it is advisable to keep the total cable run from computer to
KVM no more than 30 metres.
Keyboard and PS/2 mice - 6 pin mini-DIN male connector to 6 pin mini-DIN male
connector with all lines connected straight through (1-1,2-2 etc.). If the PC has a 5-
pin DIN AT style keyboard connector you will need a PS/2 to AT keyboard adapter
6-pin mini-DIN female to 5-pin DIN male (readily available). Cables should be no
longer than 30 metres.
RS232 serial mice - these require a special converter to connect the RS232 lines
present on the LINDY Dual/Quad PRO mouse ports to the RS232 port on a PC.
Cables should be no longer than 30 metres.

NOTE - There are several common wiring specifications for 6-pin mini-DIN to 9-pin
serial adapters. If you have an adapter that has been supplied with a mouse it may
have a completely different internal wiring to that shown above and may not be
compatible with the LINDY Extender.
Recommended cables:
3-in-1 keyboard, video and mouse combination cable - For convenience,
neatness and high video quality we recommend the LINDY brand 3-in-1 combination
cables. These cables are constructed with tri-coax video links to ensure that high
video quality is maintained. They also support DDC signalling and are colour coded
in PC99 specification colours for your convenience. These match the colours used
on the back of your LINDY Dual/Quad PRO and most modern PCs. These cables
are available in various different lengths to suit your requirements. They may be
purchased with or without the adapters for AT keyboards and RS232 serial mice.
