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
ESC Cancel current action. Escape back to the main display.
0 – 9 Used to enter numbers. ( n )
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).

Up Arrow Display next 4 users and the CPUs they are connected to. (See note below.)

The following examples show various methods of routing user 3 to CPU 5. Users and CPUs can be entered as a two digit number
or a one digit number followed by ENTER.
USR - 3 - CPU - 5 - ENTER
USR - 3 - ENTER - 5 - ENTER
USR - 0 - 3 - 0 - 5

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.
