Welcome
Thank you for purchasing the Miniview® Ultra+ KVM switch, one of the most versatile KVM switches
on the market. The New Miniview® Ultra+ is much more than a simple eight-port KVM switch. The dual
interface support allows you to connect both PS/2 and USB computers on the same switch. The multi-
platform support allows you to control Windows-based computers, Sun Solaris systems, Linux, or
even Macs by a single KVM switch. IOGEAR extended the multi-platform support by supporting the
special keys on both Sun and Mac keyboards.

Overview
IOGEAR’s new eight-port Miniview® Ultra+ KVM switch is the ideal tool to help reduce redundant hardware.
Eight monitors, mice and keyboards are simply too expensive, bulky and inconvenient for most system
administrators. Why bother when you can control all eight, or even up to 512 computers with a single
keyboard, monitor and mouse? The added audio support allows you to enjoy music while working. Just think
of the time, space and money you’ll save, and added fun.
The New Miniview® Ultra+ is much more than a simple eight-port KVM switch. The dual interface support
allows you to connect both PS/2 and USB computers on the same switch. The multi-platform support allows
you to control Windows-based computers, Sun Solaris systems, Linux, or even Macs by a single KVM
switch. IOGEAR extended the multi-platform support by supporting the special keys on both Sun and Mac
keyboards. This KVM switch also comes with the IOGEAR VSE technology, which provides excellent video
resolution - up to 2048 x 1536. Built-in AutoScan mode lets you conveniently monitor every attached
computer for a specified amount of time, while our On Screen Display (OSD) technology allows you to assign
a unique name to each computer and access it via a smooth menu-driven interface. With its 1U, 19” rack-
mountable casing and status-monitoring LEDs, the Miniview® Ultra+ is the perfect switch for your server
room or any other multi-computer environment.

Port ID Numbering:
Powering Off:
Each CPU Port on a GCS1758 installation is
assigned a unique Port ID.You can directly access
any computer on any level of the installation by
specifying the Port ID of the CPU port that the
computer is connected to - either with the Hotkey
port selection method (see p. 20), or with the OSD
(see p. 27).
If it becomes necessary to power off one of the
GCS1758 units, you must do the following:
Shut down all the computers that are attached to the
unit which do not support hot plugging feature, such
as PS/2 computers or computers with Novell OS, etc.
The Port ID is a one, two, or three digit number. It is
determined by the Stage Level and CPU Port number
of the switch that a computer is connected to.
The first digit represents the CPU Port number of the
First Stage unit; the second digit represents the CPU
Port number of the Second Stage
unit; the third digit represents the CPU Port number
of the Third Stage unit.

Operation
´ A computer attached to a First Stage unit has a
one digit Port ID (from 1-4 for the CS-1754; from 1-
8 for the CS-1758), that corresponds to the CPU
Port number that it is connected to.
Second Stage unit, which, in turn, links back to CPU
Port 2 of the First Stage unit.
Port Selection:
´ A computer attached to a Second Stage unit has a
two digit Port ID. The first digit represents the CPU
Port number on the First Stage unit that the
Second Stage unit links back to; the second digit
represents the CPU Port number on the Second
Stage unit that the computer is connected to. For
example, a Port ID of 2 3 would refer to a computer
that is connected to CPU Port 3 of a Second Stage
unit that links back to CPU Port 2 of the First
Stage unit.

• F7 SCAN:
- As each computer is accessed, an S appears in
front of the Port ID display to indicate that it is being
accessed under Auto Scan Mode.
- If you want to temporarily keep the focus on a
particular computer, you can pause the scanning
either by pressing P, or with a Left Click of the
mouse. See Auto Scan Mode, p. 20, for details.
- When you want to permanently stop scanning at a
particular location, press the [Spacebar] to stop
scanning and exit Auto Scan Mode.
The SCAN function allows you to automatically
switch among the available computers at regular
intervals so that you can monitor their activity
without having to take the trouble of switching
manually.
- The selection of computers to be included for Auto
Scanning is made with the Scan Mode setting
under the F3 SET function (see p. 31).
- The amount of time that each Port displays for is
set with the Scan Duration setting under the F3
SET function. When you want to stop at a
particular location, press the [Spacebar] to stop
scanning.

Mode in order to regain control of the console.
- If the scanning stops on an empty port, or one
where the computer is attached but is powered Off,
the monitor screen will be blank, and the mouse
and keyboard will have no effect. Simply wait –
after the Scan Duration time is up, the Scan
function will move on to the next port.
- To exit Auto Scan Mode, press the [Spacebar] or
[Esc].

computers, and blanks the Console screen. After using
this function you must log in all over again to regain

have to do to reenter the OSD is tap the OSD Hotkey.
Note:
1. When you reenter the OSD after logging out, the
screen stays blank except for the OSD Main
Menu.You must input your password before you
can continue.
2. If you reenter the OSD after logging out, and
immediately use [Esc] to deactivate the OSD
without having selected a port from the OSD
menu, a Null Port message displays on the
screen. The OSD Hotkey will bring up the Main
OSD Screen.
