NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH

INTRODUCTION

The NTI ST-nXm-U (NODEMUX) is a multi-user / universal KVM switch, (n= number of users, m= number of CPUs). It allows

multiple users, up to 8, each with a keyboard, monitor, and mouse, to communicate directly with any PC or SUN workstation

connected to the switch. A single switch can connect to up to 32 CPUs. These CPUs can be file servers, network managers, etc.

The auto-boot circuitry in the NODEMUX allows all CPUs to boot simultaneously without keyboard and/or mouse error.

Features

Users can work individually or share the same CPU.

Up to n users can work with m CPUs where n and m are the switch size acquired.

Universal input and output ports that interface cables plug into adapt to PC and SUN platform devices.

Power cycle circuit control allows the NTI switch to be powered OFF, then ON, at any time without affecting the attached

CPUs.

Power cycle circuit control allows the attached CPUs to be powered OFF, then ON, at any time without affecting the switch or

other attached CPU.

2. Connect the keyboards to the ports labeled "USER x" on the rear of the NTI Switch. (See Figure 3) Use the proper interface

cables. (See also Cable Selection Guide on page 10.) Insure that the monitors and related keyboards have the same port

numbers.

FYI: If it is desired for only a monitor to be connected to a set of user ports, an NTI keyboard cable (VKTINT-1 for

example) must also be connected to the keyboard port for that user. (The other end of the VKTINT-1 does not need to be

connected to anything.) This is required in order to enable the user of that port to switch between CPU ports on the NTI

Universal KVM switch. (See Figure 5- Cable Selection Guide on page 10 "Video-Only User".)

NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH

USING THE NTI NODEMUX UNIVERSAL KVM SWITCH

Basic Operation

The NODEMUX enables a user or several users to access any CPU at any time. Users can even share a CPU and work on the

same project – each from their own console. Resolution is supported through 1900x1200 with no degradation – guaranteed. A

Liquid Crystal Display (LCD) on the front panel indicates the port to which the user is attached. The NODEMUX can be controlled

by three methods;

•

keypad control with LCD via front panel

OSD control via the user devices

RS-232 control (see page 20)

Keypad Control

The front panel keypad and LCD display allow the user to monitor switch status and route any user to any CPU on the switch.

Along with the routing of the inputs to the outputs the keypad and LCD allow the users to configure the RS-232 control interface.

The keypad buttons perform the following functions:

Key

Action

Cancel current action. Escape back to the main display.

Used to enter numbers. ( n )

ESC

0 – 9

USR

The user device number can be entered (2 digits or 1 digit and ENTER) followed by the desired

CPU to be connected to (2 digits or 1 digit and ENTER).

Note: By default, the display will show all connections between CPUs and users, displaying 4 at a time, from the first to

the last, and repeating the cycle indefinitely. If the user presses either the up or down arrow to manually view

connections, the display will freeze on the chosen view. To resume the default cycle of displaying all connections, the

user must press and hold either the up or down arrow for 3 seconds, and then release it.

NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH

OSD Control

OSD superimposes a menu system on the user’s video screen with a list of all connected CPUs. OSD allows CPUs to be named

(with up to 12 character names). OSD then allows selection of CPUs by that name. Connected CPUs can be listed by name or

by port number. OSD Search Mode enables the user to type in the first few characters of the CPU's name and the OSD will

locate it. HELP screens assist with all OSD functions.

Security Option with Password

The security option in the OSD Control of the NODEMUX switch enables an administrator to control access to CPU ports for each

user. Up to 63 users can be created. These users have controlled access to any CPU. Only the administrator can activate or

deactivate the security features on each user port. Finally, the administrator can set a maximum idle time value after which the

current user will be logged out and the login screen displayed again. This time out does not function while the OSD is active. The

current security status, idle time out, and scan dwell time are all saved and will be restored whenever power to the switch is cycled

OFF, then ON. To reset the administrator’s password call NTI and have the device serial number of the NODEMUX switch

Enabling The Security Feature

To enable the security feature the administrator must first enter Command Mode from the keyboard using the <Ctrl> + <`> (accent

key). The OSD menu will automatically appear on the monitor. This provides a visual way to control the NODEMUX switch using

the keyboard and mouse.

The administrator , when setting the Universal KVM switch up for the first time, may want to proceed directly to the

ADMINISTRATION Mode by typing <CTRL> + <M> , then <A>, and then <Y>.

Password and User Name

The factory default settings are:

• user name = ADMINISTRATOR

• password = ADMINISTRATOR

Figure 6- Login screen

Note: The username for the administrator cannot be changed from "ADMINISTRATOR".

Once logged-in, follow the instructions on page 14 for setting up users and changing the administrator password. Once the

password is setup, if it is lost or forgotten, the administrator will have to contact NTI for assistance on clearing the password and

set it up again. Within the ADMINISTRATION Mode the administrator can setup each of the users and the limitations of their use

of the individual CPUs on the system.

When a standard user powers up the system a security screen may appear as setup by the administrator. The user will

need to login to the system by following the instructions below for the USER LOGIN. If the user does not know the appropriate

user name and password (setup by the administrator), contact the system administrator for this information. Once logged-in a

user can follow the Command Functions described on page 16 to control the system of CPUs within the limitations as determined

by the administrator.

NTI NODEMUX MULTI-USER UNIVERSAL KVM SWITCH

RS232 CONTROL

Remote Connection

The RS232 Interface is designed to meet the RS232C standard and can be controlled from any CPU or other controller with an

RS232 communications port. The pin outs for the DB9 connector on the unit are as follows:

RS232 Connector (DB9 FEMALE)

SIGNAL

None

TXD

RXD

DSR

GND

DTR

FUNCTION

no connection

Transmit Data (RXD at host)

Receive Data (TXD at host)

Data Set Ready

Signal Ground

Data Terminal Ready

Clear to Send

CTS

RTS

none

Request to Send

no connection

NOTE: Security must be disabled (see Administration Options on page 14) or user access granted (see System Access

List on page 15) on the port(s) to be selected by RS-232 control.

On the DB-9 female connector, pins 1 (DCD), 4 (DTR), and 6 (DSR) are shorted and pins 7 (RTS) and 8 (CTS) are shorted.

Therefore, CPU handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB9 cable (not null

modem) will work for most CPUs. To daisy chain multiple units, the CPU drives the input port on the first unit and the output port is

connected to the input port on the next unit etc. The last unit will have a loop back plug installed in its RS232 OUT connector.

Baud Rate

The baud rate can be changed by selecting MENU on the front panel keypad. Then select 1 for SET BAUD RATE and select the

desired baud rate of 9600, 4800, 2400 or 1200. A data protocol of 8 data bits, no parity, and 1 stop bit is used for

communications.

Unit Address and Loop Back

To allow multiple units to be controlled from a single CPU port, the RS232 control interface is designed to allow "daisy chaining"

up to 15 units. By setting the appropriate unit address with the keypad, each unit can be given a unique address (1-15). Then the

unit will only respond to commands on the bus if its address is embedded in the command.

To set the unit address using the front panel keypad,

1. Press <MENU>

2. press <2> for “SET UNIT ADDRESS“

3. enter the address number (1-15)

4. press <ENTER>.

The "loop back" plug should be on the RS232 OUT connector on the last unit in the chain. If only one unit is being controlled, the

loop back plug should be on the RS232 OUT connector on that unit.

Autostatus

When Autostatus is enabled, any output-to-input connection change in the NODEMUX will cause an Autostatus message to be

sent via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"

Example of an Autostatus message:

pc 01,01:04<CR>

which means "At the switch with unit address 01, the output (01) has changed connection to input 04."

Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the

administrator.

Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (page 20).

By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the

NODEMUX is interrupted.
