NTI UNIMUX MULTI-USER KVM SWITCH
USING THE NTI UNIMUX USB KVM SWITCH
Basic Operation
The UNIMUX switch enables a user or several users to access any CPU at any time. A CPU can be shared so that more than
one user can use a CPU and work on the same project – each from their own console. Resolution is 1900x1200 with no
degradation – guaranteed. The front panel LCD indicates the port to which each user is attached. The UNIMUX can be
controlled by three methods:
keypad control
•
OSD control
•
RS-232 control
•
Keypad Control
The front panel keypad and LCD (see Figure 8) display allow the user to monitor switch status and route any user to any CPU on
the switch. Along with the routing of the CPUs to the user devices the keypad and LCD allow the users to configure the RS-232
control interface. The keypad buttons perform the following functions:
