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

RACK MOUNTING INSTRUCTIONS  
This NTI switch was designed to be directly mounted to a rack. It includes a mounting flange to make attachment easy.  
Install 4 cage nuts (supplied) to the rack in locations that line up with the holes (or slots) in the mounting flange on the NTI switch.  
Then secure the NTI switch to the rack using four #10-32 screws (supplied). Be sure to tighten all mounting screws securely.  
Note: Do not block power supply vents in the NTI switch chassis (if provided). Be sure to allow for adequate airflow in  
front of and behind the NTI switch.  
Attach all cables securely to the switch and where necessary supply adequate means of strain relief for cables.

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".)

4. Connect a VEXT-xx-MM (and adapter if needed) from the video port of the CPU to a port labeled "VIDEO x" on the  
NODEMUX with the same port number as the keyboard. Make sure the CPU is connected to a "CPU x" port and a "VIDEO x"  
port with the same number. Otherwise the user's typing may be going to one CPU, but the user will be viewing a different  
CPU on the monitor.

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  
available.  
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.

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:

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.

Note: The RS232 connection on the switch may only have a single 9 pin "RS232" female connector. In this case, in  
order to connect multiple NODEMUX units together, a Matrix-Y-1 cable must be used. (see Figure 15). No loop back  
plug will be used with this configuration. See Figure 16 for the pinout of the Matrix-Y-1 cable.

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.
