RACK MOUNTING INSTRUCTIONS
This NTI switch was designed to be directly mounted in a rack and includes a mounting flange to make attachment easy.
Install 4 cage nuts (supplied) to the rack in locations that line up with the holes (or slots) in the mounting flange on the NTI switch.
Then secure the NTI switch to the rack using four #10-32 x3/4” screws (supplied). Each screw should be of sufficient length to
go completely through the NTI mounting flange, rack frame and fully engage all threads in the captive nut. Be sure to tighten all
mounting screws securely.
Do not block power supply vents in the NTI switch chassis (if provided). Be sure to enable adequate airflow in front of and
behind the NTI switch.
Attach all cables securely to the switch and where necessary supply adequate means of strain relief for cables.

INSTALLATION
It is not necessary to turn OFF power to CPUs or monitors during this installation unless RS232 is going to be connected. All
cables, except for the RS232 cables, may be hot plugged.
If using RS232 Control see RS232 section on page 38 for more information. Observe normal precautions when connecting the
RS232 cables to the CPU. Refer to the owner’s manual for the CPU being connected for precautions, if any.
1. Connect the 15HD male cable end from each user monitor to the female black 15HD ports marked “MONITOR x” on the rear of
the UNIMUX switch (see Figure 2 ). If a touch screen monitor is being connected (models with touch screen support only),
connect the USB cable from the monitor to any one of the USB type A connectors in the same user device port group (see
Figure 3 ).

2. Connect the user devices to the USB type A female ports labeled with the USB symbol ( ) on the rear of the UNIMUX
switch (see Figure 4 ). Ensure that the monitors and related user devices are connected to ports from the same device port
group.
Note: If there are three (3) USB type A female ports present (models with touch screen support only), then the third USB
port is available for connection of a USB cable from a touch screen type monitor. The USB ports are not device specific,
so the mouse, keyboard, and USB cable from a touch screen type monitor (or other suppported device) can be
connected to any of the available USB ports present.
Note: If device cables are not long enough to reach the UNIMUX switch, they can be extended either 5 or 10 meters
using either 1 or 2 NTI USB2-AA-5M Active USB 5 Meter Extensions (see Figure 5)- purchased separately. Using USB-
C5-LC you can extend device cables up to 150 feet. Contact your NTI salesperson for more details by calling (800) 742-
8324 (800-RGB-TECH) or [phone] or visit our website at http://www.networktechinc.com.

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 the RJ45-to-DB9 adapter supplied and connect the adapter to the RS232
port on the control terminal. Follow the instruction under “RS232 Control” on page 38 for configuration and use of the RS232
control feature.

CAT5 Connection
If the CAT5 extender option is present, a CAT5 cable up to 300 feet long can be connected between the “USERx” ports that
are RJ45 female connectors and an ST-C5USBV-R-300 extender Remote Unit (sold separately). We will use “USER 3” for
this example.

1. Position the ST-C5USBV-R-300 such that the CAT5 cable, the monitor cable, the keyboard and mouse, and the AC adapter
power connector can each reach the ST-C5USBV-R-300 comfortably.
2. Connect the monitor cable to the 15HD female VIDEO port on the ST-C5USBV-R-300. (See Figure 10)
3. Connect the devices to the ST-C5USBV-R-300.
a. Connect the USB keyboard cable to one of the USB Type A female ports labeled "USB DEVICES" on the back
of the ST-C5USBV-R-300. (Either one will work.)
b. Connect the USB mouse cable to the remaining USB Type A female port on the back of the ST-C5USBV-R-
300.

4. Plug the power cord from the monitor into a power outlet.
5. Connect the AC adapter power connector to the 9VDC port on the Remote Unit and plug it into a power outlet. The “Power”
LED (Green) on the CAT5 connector of the Remote Unit should illuminate, indicating that a proper power connection has
been made.
6. Turn ON the monitor. The monitor will display an image coming from the CPU that User 3 is connected to via the UNIMUX
switch. The yellow communication LED on the Remote Unit (see Figure 10) should blink indicating there is proper
communication with the UNIMUX.

Ethernet Connection
If the Telnet Interface (page 44) will be used, an Ethernet connection to the Local Area Network (LAN) must be made using CAT5
cable with RJ45 connectors attached. Wiring between connectors should be straight through (pin 1 to pin 1, pin 2 to pin 2, etc..)
Connect a CAT5 cable between the connector labeled "ETHERNET" and the LAN (see Figure 11).

Remote CPU Access
In order to have access to a User port from anywhere either over a network or through a serial connection via a PSTN, an
INTERMUX-KVMUIP can be installed to one of the USERx ports. This will provide user control over any of the CPUs connected
to the UNIMUX switch.
Install the INTERMUX-KVMUIP as illustrated below. See manual that accompanies the INTERMUX-KVMUIP for more details.
