MOUNTING
The SPLITMUX-4K-4RT can be purchased in a 1RU case with parts and hardware for mounting in a rack as a single unit
(SPLITMUX-4K-4RT-R) or as a dual unit (SPLITMUX-4K-4RT-2R). (SPLITMUX-4K-4RT is for desktop mount only. The
SPLITMUX-USB4K-4RT comes standard as a rackmount unit.) Follow the instructions below for assembly and installation.
Whether the SPLITMUX will be mounted as a single or a double, brackets will be attached to the case to enable mounting ears or
a connector plate to be attached.
1. Attach the ear brackets to the SPLITMUX. The holes in the brackets should line up with pre-threaded holes in the sides
of the SPLITMUX. Tighten the screws securely.
Note: If the ear brackets are applied to the rear, the cable management tray cannot be used.
Figure 1- Attach ear brackets to front corners or rear corners.
2. If the ear brackets have been applied such that the front will face out, assemble the cable tray to the holes in the rear of the
SPLITMUX as shown below.
Figure 2- Attach cable tray (if applicable)
FYI: The same hole pattern is
provided at the front and rear of
the SPLITMUX, enabling the
SPLITMUX to be mounted with
the front facing out or rear
facing out.

SPLITMUX Quad Screen 4K Multiviewer

Single-SPLITMUX mounting
1. To mount a single SPLITMUX in a rack (SPLITMUX-4K-4RT-R), attach the rack mounting ears to the ear brackets using the
#6-32 x 1/4” screws provided. Tighten all screws securely.
Figure 3- Attach rack ears
Figure 4- Assembled unit, ready to mount in rack
2. Install 4 cage nuts (provided) to the rack in locations that line up with the holes in the mounting ears on the SPLITMUX.
3. Secure the SPLITMUX to the rack using the four #10-32x3/4” screws provided. Be sure to tighten all mounting screws
securely.
Note: Do not block power supply vents in the SPLITMUX case. Be sure to enable adequate airflow in front of and
behind the SPLITMUX.

SPLITMUX Quad Screen 4K Multiviewer
6
Dual-SPLITMUX mounting
1. To mount a dual SPLITMUX in a rack (SPLITMUX-4K-4RT-2R), attach the rack ears to the far left side of the left SPLITMUX
and right side of the right SPLITMUX using the #6-32 x 1/4” screws provided. Then install a connector plate to join the two
SPLITMUXs in the front.
Figure 5- Attach ears and connector plate
2. Install a cable tray connector between the cable trays using 4 more #6-32x1/4” screws.
Figure 6- Attach cable tray connector

Reversible Mounting Assembly
If the SPLITMUXs will have the cable connections facing the front of the rack, then two more ear brackets will need to be installed
to the rear corners of the cases that will be closest to each other. (Install these before attaching the connector plate to the front.)
Once the ear brackets are applied, the ears and connector plates can be attached.
Figure 7- Assembly method for SPLITMUX with cables facing forward
Figure 8- Assembled SPLITMUX-4K-4RT-2R
3. Tighten all screws securely. The SPLITMUX is ready for mounting.
4. Install 4 cage nuts (provided) to the rack in locations that line up with the holes in the mounting ears on the SPLITMUX
assembly.
5. Secure the SPLITMUX to the rack using the four #10-32x3/4” screws provided. Be sure to tighten all mounting screws
securely.
Note: Do not block vents in the SPLITMUX case. Be sure to enable adequate airflow in front of and behind the
SPLITMUX.

INSTALLATION
1. Connect each of the HDMI or DVI video sources to the ports on the SPLITMUX marked “HDMI IN x” (x = 1-4).
2. Connect the display to the port marked “HDMI OUT”.
3. Connect the power supply to the power jack and plug it in. In approximately 20 seconds, the LED on the SPLITMUX will
illuminate red (standby).
4. Press the switch on the front to power the SPLITMUX ON. Within 20 more seconds the LED will change from red to green
(ON) and the SPLITMUX will be ready to use.
5. For keyboard and/or mouse control of the OSD menu of the SPLITMUX, connect a USB keyboard and/or mouse to the USB
type A ports labeled “KYBD/MOUSE” on the SPLITMUX. On models supporting transparent USB device connection
(SPLITMUX-USB4K-4RT), the keyboard and mouse connected to these ports will also control the keyboard and mouse functions
on any connected PC. (See Figure 10)
Figure 9- Video Source/Display Connections-SPLITMUX-4K-4RT
Note: If the connected display does not
support an HDMI input (typically it will
have at least one HDMI input port), the
display will not be compatible.

6. For SPLITMUX units supporting USB CPUs (SPLITMUX-USB4K-4RT), a USB2-AB-xM cable (where x = 0.5 meter, 3,6,10 or
15 feet)(sold separately) can be connected between a USB port on the CPU and a “CPU IN x) port corresponding with the
“HDMI IN x” port the video from the CPU is connected to.
7. Connect any desired USB devices to the ports labeled .
With the connections made in steps 6 and 7, the keyboard and mouse connected to the “KYBD/MOUSE” ports and any USB
device connected to the ports labeled will be active for the connected CPU when the video from that CPU is selected in
the SPLITMUX.

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
SPLITMUX. 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 11- RS232 Terminal Connection
Ethernet Connection for Remote User Control
To make a remote connection, over the Ethernet, from anywhere on the local area network, connect a CAT5/5e/6 Ethernet
cable with RJ45 male connectors on the ends, wired straight through (pin 1 to pin 1, pin 2 to pin 2, etc.). Up to 8 users can
connect to the SPLITMUX using the Ethernet at a time.
Note: A direct connection from a computer’s Ethernet port to the SPLITMUX “ETHERNET” port may also be made using
the same cable.
Figure 12- Ethernet connection

POWER ON
When you plug in the AC adapter between the SPLITMUX and your power supply, with the power switch OFF (switch towards
“O”), the LED on the SPLITMUX will illuminate red after approximately 20 seconds. To use the SPLITMUX, press the power
switch to ON (switch towards “I”). After 20 more seconds the LED will change from red (standby) to green (ON). The
SPLITMUX is now powered up and ready to use.
When powering the SPLITMUX OFF, always press the power switch to OFF (switch towards “O”). Then wait 5 seconds or so
until the green LED changes to red. Once it is red, you can then safely unplug the SPLITMUX from the power source.
WARNING: If you unplug the power source before powering OFF the SPLITMUX at the power switch, you may lose saved
data and configuration information.

CONTROL METHODS
The SPLITMUX can be controlled using any of six methods;
Standard Mode using the front panel buttons
OSD Mode using the front panel buttons and/or keyboard and mouse,
Using the Command Line Interface either through RS232 or remote connection
Using a Text Menu either through RS232 or remote connection
Using a hand-held IR Remote Control
Remotely through the Web Interface using an Ethernet connection.
Front Panel Buttons
The buttons on the front panel have two separate sets of functions, depending upon what mode the SPLITMUX is in; Standard
Mode or OSD Mode.
Standard Mode
In Standard Mode, the left 4 buttons control which video source is viewed as the active image on the monitor, whether the
SPLITMUX is in Full or PiP mode. The right 4 buttons determine which mode format the monitor will display the video signals in.
When FULL is pressed, the input selected using buttons 1 through 4 (or “active” image) will be the only image on
the display. The audio from the selected input will also be heard provided the audio input is set to "Automatic".(See
pages 23 or 60)
