RACKMOUNTING 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.

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.

NTI UNIMUX SERIES USB KVM SWITCH
Power-Up Sequence
• 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.
Immediately after powering ON the UNIMUX, the following splash screen will appear on the monitor (ex c ept on 2-port model):
If the security option is enabled (see page 12 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.
Limitations
• Only USB input device or hub cables can be connected to the UNIMUX at the USB Type A female ports labeled "DEVICES".
(See Features and Functions on page 3, item 11.)
• A USB hub (single or multi-port) can be used provided only USB input devices are plugged into it.
• Only a USB Windows or SUN keyboard or USB mouse may be connected to the USB port on a USB MAC keyboard
• A maximum of 8 input devices may be connected to the UNIMUX either directly or through hubs.
See Fig. 7 for some examples of input device combinations that can be used with the UNIMUX.

NTI UNIMUX SERIES USB KVM SWITCH
USING THE UNIMUX USB KVM SWITCH
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 w hich port (and corresponding CPU) is being connected to the monitor
and input devices.
The UNIMUX can be controlled by three methods:
• front control panel using touch-switches and LEDs
• keyboard control through Command Mode
• mouse clicks from within some menus of OSD Command Mode
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 in "Basic Command Mode" on page 9 and in
"User Access Functions" starting on page 18). 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 either of two methods:
• Basic Command Mode- operated strictly by using keyboard commands as instructed below. Basic Command Mode
is only applicable in UNIMUX-USBV-2.
• OSD Command Mode- operated using the keyboard and mouse in conjunction with OSD menus superimposed
onto the monitor. For all models other than UNIMUX-USBV-2, use the menus as instructed on page 12.
By pressing <Ctrl> + < ` > (accent key), the user can enter Command Mode (either Basic, or OSD). 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.

MODES OF OPERATION
Basic Command Mode
In order to control the UNIMUX with the keyboard connected, Command Mode must be enabled. To enter Command Mode from
the keyboard:
Press
Ctrl
+
NOTE: Basic Command mode is only used in a UNIMUX-USBV-2. All other UNIMUXUSBV-x switches have OSD installed. To control these models, proceed to “OSD
CONTROL” on page 12. If this is a UNIMUX-USBV-2, continue on this page.
When the COMMAND LED is illuminated, all 3 status lights on the keyboard will illuminate (if they aren't already due to caps lock,
scroll lock, and/or num lock) to indicate that Command Mode is enabled and the following functions are available:

Scan Mode
To activate or deactivate Scan Mode press <S> while in Command Mode. When in Scan Mode the switch scans to each port
with a CPU powered-ON. (The SCAN LED on the front panel will illuminate and remain ON while in Scan Mod e. ) T he port with
the CPU powered-ON remains active while in use until it becomes idle for the configured dwel l time (default time-out period is 5
seconds) before switching to the next powered-ON CPU port. See Command Mode section above for configuring the scan dwell
time.
Note: The keyboard and mouse must remain idle for the full scan dwell time before the switch selects the next active
port.
