RACK MOUNTING INSTRUCTIONS
This NTI switch was designed to be mounted to a rack or to sit on a desktop. It includes rackmount ears to make attachment to a
rack easy, and rubber feet to be applied to the bottom of the case if it will instead sit on a flat surface. If this will sit on a flat
surface, simply apply the rubber feet to the bottom of the case in each of the 4 corners.
To Mount to a Rack
1. Attach the ears to the switch using the 6-32x3/16" flat Phillips-head screws (6) provided as shown in the illustration below.
The holes in the ears should line up with pre-threaded holes in the sides of the NTI switch. Tighten the screws securely.
Figure 1- Secure rackmount ears to switch
2. Install 4 captive nuts (not provided) to the rack in locations that line up with the holes in the mounting ear on the NTI switch.
3. Secure the NTI switch to the rack using four 3/16" diameter screws (not provided). Each screw should be of sufficient length
to go completely through the NTI mounting ear, rack frame and fully engage all threads in the captive nut. Be sure to
tighten all mounting screws securely.
4. Attach all cables securely to the switch and where necessary supply adequate means of strain relief for cables.

4. Power-up
•The UNIMUX can be powered at any time.
•The CPUs can be powered at any time although if a CPU needs a keyboard and/or mouse at power-ON it should be powered
after connecting to and powering-ON the UNIMUX.
•USB input devices (keyboard and mouse) can be hot plugged to and from the UNIMUX at any time.
Note: The order in which the CPUs and switch are powered up does not matter. A power strip can be used.
Immediately after powering ON the UNIMUX, the following splash screen will appear on the monitor if the OSD option is built into
the switch:
If the security option is enabled (see page 15 for details on the
"Security Option"), when the UNIMUX is powered up the user will
be prompted for a username and password to continue. If the
security option is not enabled the monitor will display the desktop
image for the connected CPU and the user can continue with
normal operation of the connected CPU.
RS232 Connection
If RS232 control will be used, connect one end of the CAT5 patch cable (supplied) to the port labeled “RS232” on the rear of the
UNIMUX. Plug the other end of the CAT5 cable into either the RJ45-to-DB9 or RJ45-to-DB25 adapter supplied, and connect the
adapter to the RS232 port on the control terminal. Follow the instruction under “RS232 Control” on page 34 for configuration and
use of the RS232 control feature.

USING THE UNIMUX USB KVM SWITCH
Basic Operation
Once the UNIMUX is properly connected, the UNIMUX will enable a connection to be made between the CPUs attached to its
VIDEO and CPU ports and the monitor and input devices attached to the MONITOR and DEVICES ports. The LEDs on the
control panel of the UNIMUX will illuminate depending on which port (and corresponding CPU) is being connected to the monitor
and input devices.
The UNIMUX can be controlled by four methods:
•front panel control using touch-switches and LEDs
•OSD control via the user devices (models with video support only)
•RS232 control (see page 34)
•Telnet Interface- via command line interface (page 40)
Front Panel Control
There is a touch-switch and LED on the front panel of the UNIMUX for each CPU the switch will connect the monitor and
input devices to. Pressing any touch-switch on the front panel of the UNIMUX will connect the corresponding CPU to the monitor
and input devices.
Holding down any front panel touch-switch for more than 2 seconds will cause the UNIMUX to cycle through all modes of
operation including COMMAND, BROADCAST, SCAN, and NORMAL (described starting on page 20). The three MODE LEDs on
the front panel indicate which mode is selected. Release the touch-switch when the LEDs indicate the desired mode. When no
mode LEDs are illuminated the user is in Normal Mode controlling directly the CPU to which the user is connected through the
UNIMUX.
Keyboard Control
Keyboard control of the UNIMUX can be achieved using OSD Command Mode. Command Mode is operated using the keyboard
and mouse in conjunction with OSD menus superimposed onto the monitor. For all models use the menus as instructed on page
12.
By pressing <Ctrl> + < ` > (accent key), the user can enter Command Mode. Once in Command Mode, typing a series of
commands will cause the UNIMUX to connect the user to any one CPU connected to the switch. Pressing the <Esc> key will exit
Command Mode.
