RACKMUX SINGLE-PERSON INSTALLATION
Your NTI RACKMUX Drawer was designed for easy installation by one person with a minimum of tools and effort. Follow the
simple steps below to quickly install your RACKMUX Drawer.
If you would like to see a video of this installation, see the “single-person-installation”video .
1. Locate and unpack the hardware bag. Your hardware bag will include all items necessary to install the specific RACKMUX
model (see the manual that accompanied your RACKMUX drawer), including the following hardware unique to the Single-Person
hardware installation:
10- #10-32 cage nut
2- #10-32 x 1/2” flat-head machine screw
8- #10-32 x 3/4” pan-head machine screw
Toinstall the rails you will need only a tape measure and Phillips screwdriver.
2. Unpack the left and right rail assemblies. Each are labeled “Right Front” and “Left Front” to indicate their intended position and
orientation. Extend each rail assembly to the dimension required for your rack. Rail assemblies are adjustable to fit within a rack
between 24” and 40” in depth.
Rail assemblies are adjustable in length from 24” to 40”.

3. Install six #10-32 cage nuts at the front of the rack in positions where the RACKMUX will be mounted (three in each side).
Install four more cage nuts at the rear of the rack in positions straight across from the upper and lower cage nuts installed in front.

4. Install the right rail assembly. The end with the label “Right Front” mounts to the front rack support. Install only the center
screw through the rail flange to the rack support and cage nut using the #10-32 x 1/2” flat head machine screw provided. (See
image below.) Do not tighten at this time. Install the left rail assembly in the same fashion. The end with the label “Left Front”
mounts to the front rack support.
5. Install two #10-32 x 3/4” pan-head screws in the rear of each rail assembly as shown below. Do not tighten at the time.

9. Tighten securely the four screws applied to the rear rail flanges in step 4.
10. Make your cable connections according to your RACKMUX Drawer instructions.
Your NTI RACKMUX Drawer is now installed and ready for cable connections.
There should
be a total of
six screws at
the front now.

CABLE CONNECTIONS
Connect Video Sources
1. Connect each of the HDMI video sources to the ports on UNIMUX marked “HDMI Inx” (x = 1-16).
2. Connect the power cord to the AC input and plug it in.
3. Press the switch to power the RACKMUX ON. In approximately 40 seconds the UNIMUX will boot up and be ready to use.
4. The RACKMUX keyboard provides keyboard control of the OSD menu of the UNIMUX. The UNIMUX supports transparent
USB device connection such that the keyboard and touchpad mouse will also control the keyboard and mouse functions on any
connected PC.
5. For each video source that is a PC, connect a USB2-AB-0-5M-5T cable (sold separately) between a USB type A female user
device port on a CPU and a USB Type B female port on the SPLITMUX.
Figure 7- Connect each CPU and video source
6. Power-ON the video sources and CPUs.
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 RACKMUX.
Note: The order in which the CPUs and switch are powered up does not matter. A power strip can be used.
7. Power-ON the RACKMUX. (The RACKMUX can be powered at any time.)

Terminal Connection for RS232
If control via serial connection is going to be used, serial control can be achieved by connecting a control terminal to the “RS232”
port .
To use the “RS232” port, connect one end of a CAT5 patch cable (supplied) to the port labeled “RS232” on the rear of the
UNIMUX. Plug the other end of the CAT5 cable into an RJ45-to-DB9F adapter (supplied), and connect the adapter to the RS232
port on the control terminal.
Figure 8- RS232 Terminal Connection
Connect Extra Device
On the front of the RACKMUX is an additional USB Type A port to be used, if desired, for an extra accessory. Any low or full
speed USB device may be connected to this port to be used. This port is fully compliant with USB standard 1.1.
Note: In order for the optional USB device port to be usable, the USB port on the rear of the RACKMUX must be
connected to a USB enabled CPU (a 2 meter USB cable is supplied).
Note: If a USB keyboard or mouse is connected, operation of the RACKMUX keyboard or mouse may cause
unpredictable results. Do not try to use both mice or both keyboards at the same time.
Note: If a USB 2.0 device is
connected to the optional
USB device port, it will
operate at USB 1.1 speed.

CONTROL METHODS
The UNIMUX, when built into a RACKMUX, can be controlled using any of three methods;
Command Mode using the local keyboard, and touchpad mouse
Mouse clicks from within some menus of Command Mode
Using the Command Line Interface through RS232
Command Mode
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 RACKMUX user. The RACKMUX keyboard and mouse will, by default, control the PC supplying
the active video. The keyboard and mouse can also be used for controlling Standard Mode functions as well as OSD Mode.
Keyboard Control
Keyboard control of the UNIMUX can be achieved using Command Mode - operated using the RACKMUX keyboard and mouse in
conjunction with OSD menus superimposed onto the monitor.
By pressing <Ctrl> + < ` > (accent key), the user can enter Command Mode. The NumLock, CapLock and Scroll Lock LEDs
will illuminate and stay ON while in 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.

USER ACCESS FUNCTIONS
Introduction
The OSD menu enables a user to name the CPUs connected to the UNIMUX and connect to them using that name from a single
keyboard and mouse. The OSD is positioned on the user's monitor, displaying 8 CPU names at a time. The screen can be used
for switching as well as editing the CPUs’ names. Through the OSD menu, the user can operate the UNIMUX to have the switch
cycle through 3 extended modes of operation: COMMAND, BROADCAST, and SCAN .
Command Mode
When entering the Command Mode from the keyboard using the <Ctrl> + <`> (accent key), the NumLock, CapLock and Scroll
Lock LEDs will illuminate and stay ON and the OSD menu will automatically appear on the monitor. This provides a visual way
to control the UNIMUX.

The user can enable or disable the "Stop USB Device" Reminder notice. While enabled, any time the user attempts to change to
a different port number, a warning message will pop up forcing a decision to either proceed with or cancel the attempt. This
provides opportunity for the user to properly eject a USB flash drive or any other device that may be harmed by an abrupt loss of
connection between the user and the PC the flash drive is connected to.
