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
with LCD via front panel
•
OSD control
via the user devices
•
RS-232 control
(see page 29)
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:

MENU
The RS-232 menu is displayed. This allows the baud rate to be set at 9600, 4800, 2400 or 1200 baud and the
unit address to be set to 1 - 15. See RS-232 control on page 29.

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