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:

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.
