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:

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).

 

 

 

CPU

Used following single digit user entries.

 

 

 

 

ENTER

Used to enter commands or values.

 

 

 

Up Arrow

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

 

 

Down Arrow

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

 

 

MENU

The Configuration Menu is displayed. See RS-232 control.

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.
