MOUNTING
The SPLITMUX-4K-4RT can be purchased in a 1RU case with parts and hardware for mounting i n a ra ck 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.
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.
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.

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)
When QUAD is pressed, images from all 4 inputs will be displayed equally on the monitor. The audio from the last
active image will continue to be heard.
When PIP is pressed, the active image will occupy the entire screen and the images from the remaining inputs will
be displayed in lower resolution on the right side of the screen.
When CUSTOM is pressed, the images will be displayed in whatever way you have the SPLITMUX configure d to
present them. Each input can be sized and positioned on the screen as desired.
In FULL screen mode, only the active video source will be displayed. The image will be viewed at full size
and up to 4K resolution.

SPLITMUX Quad Screen 4K Multiviewer
In PIP mode (right) , either 2, 3 or all 4 video sources can be
displayed, with the active source being displayed in its
entirety on the full screen and the remaining selected
images at a reduced resolution for simultaneous viewing.
The position of the reduced images can be configured for
preferred viewing. The maximum output resolution is 1080p
in PIP mode.
In CUSTOM mode (below) the 4 video sources can be
placed where ever you want, at what ever size you want.
The amount of each source that is viewed is determined by
your configuration. The maximum output resolution
is 1080p in Custom mode.
In QUAD screen mode, all four video sources share the screen
equally. Each video source is displayed completely. The
maximum output resolution is 4K in Quad mode.

USE AND OPERATION VIA WEB INTERFACE
A user may configure the settings of the SPLITMUX using the Web Interface via any web browser (see page 2 for supported web
browsers). To access the Web Interface, connect the SPLITMUX to the Ethernet (page 10). Use the Device Discovery Tool
(page 15) to setup the network settings. Then, to access the web interface controls, the user must log in.
Note: In order to view all of the graphics in the Web Interface, the browser’s JavaScript and Java must be enabled.
By default, the SPLITMUX is configured to dynamically assign network settings received from a DHCP server on the network it is
connected to. (This can be changed to a static IP address to manually enter these settings in the Network Settings on page 20.)
The SPLITMUX will search for a DHCP server to automatically assign its IP address each time the unit is powered up. If the
SPLITMUX does not find a DHCP server, the address entered into the static IP address field (page 20-default address shown
below) will be used. If a DHCP server on the network has assigned the IP address, use the Device Discovery Tool to identify the
IP address to enter when logging in to the SPLITMUX, or use the OSD menu to view the System Info page.
Note: The computer using the Device Discovery Tool and the NTI Device must be connected to the same subnet in order
for the Device Discovery Tool to work. If no devices are found, the message “No Devices Found” will be displayed.

Audio Level and Gain
The Audio level bar indicates the sound level output for the left and right speakers of that input chann el. T he level “ -96dB”
indicates minimum sound output and “0dB” indicates maximum sound output. The audio level can also be viewed on the display
(see Figure 23) when enabled through the web interface (see Figure 26).
The Audio Gain provides control over the Audio level output by the SPLITMUX. Drag the slide button to the left or right to adjust
the audio level. If the Audio level indicates -96dB for an input channel, it means there is no audio at that source.
Note: If sliding the Audio Gain button towards 0.00 dB results in the Audio level reaching 0 dB, back it down towards
the left enough to reduce the Audio level to at least -3dB (red arrow in Fig. 20.). Levels higher than 0dB will likely result
in significant audio static or noise.
Note: The audio that is heard is determined by the Audio Mode Settings (below) and the Input Channel selected under
Current Output Mode (page 17).

The Aspect Ratio can be configured to be a Fixed or Free Ratio.
When set to Fixed Ratio, no matter what size you drag the channel to be,
the viewed image will retain the ratio of the source.
When set to Free Ratio, the displayed video will adjust to whatever size or
shape you have dragged that channel to be.
To switch between aspect ratio settings, click on the drop-down arrow and select
the desired setting.
Note: When you switch from Free Ratio to Fixed Ratio after having resized
the image, the image on that channel will automatically crop to retain the
displayed size and shape while adjusting to the proper aspect ratio.

The border color is selected from an array of options by clicking on the arrow.
Control the level of transparency for an input by sliding the “Transparency” button to the right.
Use the Zoom slider to zoom in on the image to enlarge your view of the source. Zoom range is from 100% (full size) to 500%.
With the image zoomed, you can also use the “Pan and Crop” feature (see Alignment Tools- page 27) to bring your preferred
area of focus into view.
Place a checkmark in “VOL-L” and/or “VOL-R” to display audio levels to the left and right of the video on the display for that
channel. (See Figure 23 on page 23).
Place a checkmark in “UMD” (Under Monitor Display) to show the channel name beneath the video on the display.
Note: The audio level and UMD will only be viewable on the display when the SPLITMUX is in Custom Mode.
Place a checkmark in “Enable Audio” to hear the audio from that channel. Remove the checkmark to disable audio, but this will
only effect audio operation while in Custom Mode.
If your adjustments result in distortions in the channel and you want to start from scratch, click on “Default Size/Pos” button. The
channel resolution will either change to a full screen display at the native resolution for that channel, or to a combination of the
native resolution and the set output resolution of the SPLITMUX. If the output resolution is set smaller than the channel (source)
resolution, then the resulting display image will be limited by the size and aspect ratio of the output setting.
For a specific display dimension for the selected channel, enter the desired values under “Width” and “Height”.
Enable/Disable Channels
You can enable or disable each channel being displayed, and provide labels for the
channels. These labels are displayed in this interface as well as on the display
device when “UMD” (under monitor display) is selected for the channel.
Note: Custom Mode Settings will not support resolution above 1920x1080p. If
resolution is set above 1080p while in PIP mode, the screen will go blank. If set

In order to expand the number of video inputs that can be monitored by one display, SPLITMUXs can be connecte d in a cascaded
configuration.
To cascade SPLITMUXs, simply connect the output port of any downstream SPLITMUXs to the input port of an upstream
SPLITMUX. Any input sources will be viewable from the monitor connected at the most upstream SPLITMUX. Using Cascade
Settings under Administration, configure the SPLITMUX for the connection method that will be employed.
Figure 28- Cascading SPLITMUXs
Note: When cascading SPLITMUXs,
make sure the Output Settings of all
slaves are set at or below
1920x1080p. The Input of the
Master does not support higher
resolution settings from the slave
units.
To reduce cost, we recommend
using the SPLITMUX-HD-4RT for any
units connected as Slaves in a

Notes:
Each SPLITMUX must be properly configured in the cascade settings in order to view the inputs at the master level.
The Custom Mode layout will display the custom mode layout outline of each slave connected to it.
The Current Mode setting of the slave will determine what video is viewed and audio is heard at the master level, regardless of
what the custom mode layout is set at.
The configuration menu for each slave is accessible from the web interface of the master SPLITMUX with a proper cascade
configuration.
To adjust the custom layout settings for a slave, you must be at the IP address of that slave.
The dotted lines in the custom layout are indication of connection to a slave on that channel of the SPLITMUX. To access that
slave, double-click on the channel image. Allow a few seconds for the screen to update. You will see that the IP address in the
URL bar has updated.
In order to control the configuration of any slave unit from the web interface, that unit must be connected to the LAN through the
Ethernet port. If web interface control is not required for a slave unit, connection to the Ethernet is not required in order to use it
in a cascaded configuration.
With a proper cascade configuration at each level, the IP hierarchy will be displayed in tabs on the Custom Mode Settin gs page.

Administration- System Information
The System Information page provides firmware version, serial number (version 1.1 and later), MAC address, network settings
and input connection status for the SPLITMUX. This information is particularly helpful when the IP mode is set to “DHCP With
Failover” (the default setting) because it displays the DHCP server-assigned settings, regardless of the network setting applied on
the Network Configuration page (page 20) which only apply when the IP mode is set to “Static”.
Figure 32- System Information page
Note: The System Information page always shows the assigned IP address whether the IP Mode is set to “Static” or
“DHCP with Failover”. (See page 20) This information is also easily accessed from the OSD screen using the front
panel buttons.

COMMAND LINE INTERFACE
The SPLITMUX can be controlled using a command line interface from either a terminal connection to the “RS232” serial port
(page 10) or through an Ethernet connection (page 10).
RS232 Control
The RS232 Interface is designed to meet the RS232C standard and can be controlled from any CPU or other contro ller with an
RS232 communications port. The pin-out for the RJ45 connector on the unit is as follows:
RS232 (RJ45) CONNECTOR
PIN SIGNAL FUNCTION
1 - No connection
2 - No connection
3 RX+ Receive data (TXD at host)
4 GND Ground
5 - No connection
6 TX+ Transmit data (RXD at host)
7 - No connection
8 - No connection
A 5 foot patch cable and adapter, RJ45-to-DB9, have been provided for connection to most CPUs (see page 10).
Baud Rate
The baud rate can be changed using the OSD menu (page 56), using T elnet commands (page 38) from the RS232 commands
(page 37), from the Text Menu (page 42), or through the WEB Interface (page 18). The baud rate can be set to 115200, 57600,
38400, 19200, 9600, 4800, 2400, or 1200. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications.
The default baud rate setting is 9600. The terminal should be in VT100 terminal mode.

SPLITMUX Quad Screen 4K Multiviewer
RS232 Command Protocol
CPU controller commands supported by the unit are defined below. All commands must be terminated with a <CR> (carriage
return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the
Command Definitions table (below). All characters in the command string are case sensitive (see Command Definiti ons table),
and all numbers below 10 must have a leading 0 (ex: 1 = 01).
Legend:

This will return the unit size. RU must be in upper case. There is a space (press the <Spacebar>) between RU
and 01. 01 is the default serial address of the unit.
This will connect input 2 to output 1. The first 01 is unit serial address; 02 is input 2; the last 01 means output
1. (There is only 1 output, so this value will always be 01). There is a space between letters and numbers,
but a comma between just number values.
This will change output mode to PIP. The first 01 is the serial address. Change as needed for the SPLITMUX
you are controlling. 03 is the mode setting desired (PIP). The second 01 means output 1.

Operation
Operation of the IRT-UNV is intuitive. The number of button presses required to complete any operation is kept to a
minimum. This is accomplished using intelligent software within the NTI SPLITMUX. As a button is pressed, the PWR/ST ANDY
green LED on the SPLITMUX will flash red to indicate it has received the signa l (whether that signal is valid to cause a chan ge or
not).
Changing Ports
To change the Active input port (FULL screen mode),
press <IN>, then the port number (1-4).
To change modes,
For Full Screen Mode press <OUT>, then <1>
For Quad Screen Mode press <OUT>, then <2>
For PIP Screen Mode press <OUT>, then <3>
For Custom Screen Mode press <OUT>, then <4>
To have any command take immediate effect, end it by pressing <ENTER>. (Example- press <IN> then <1> then
<ENTER> to change to Active input port 1) Otherwise, there will be a 2 second delay for it to take effect.
When changing the Active input port, the audio from that
input port will also be heard provided the audio mode for the
input is set to "Automatic" and no other audio mode for an
input port is set to "Enable". See pages 23 or 61 for more.
Audio Control
Toggling Mute On/Off: Press <Audio>, then the port number (1-4), then <Mute>
Changing Audio Gain (Volume): Press <Audio>, then the port number (1-4), then Vol+ / Vol- (can be pressed once or
many times)
Save and Recall
To save a configuration of channels on the display using the IR Remote control, the <Save> and <Recall> buttons are provided.
Up to 10 configurations can be saved and recalled. Once the display has the configuration you want to be able to quickly return
to, press the <Save> button followed by two digits (01-10). To recall a configuration at any time, press the <Recall> button
followed by the associated two digit number.
Multiple Switch Control
All NTI SPLITMUX-4K-4RT will work with the same IRT-UNV IR Remote control. As a result, a user with multiple NTI
SPLITMUXs may find that, if the switches are installed too close together, both switches may respond to an IR command intended
only for one switch. Also, the user may want to control multiple s witches with a single remote, instead of having one remote per
switch. To control more than one SPLITMUX from one R emote, the IRT -UNV IR Remote provides the “S YS” button, which can be
used to select the specific NTI switch to be controlled.
All switches will have the capability to allow the user to set the switch address (1-15) (see page 1 8, 42 or 56 ). The default
switch address is 1. Each switch to be separately controlled must be set to a different address prior to using the Remote Control.
With the addresses set;
1. press the <SYS> button on the IRT-UNV,
2. followed by a single (i.e. <1>) or two digit number (i.e. <0> then <1>) corresponding to the address of the switch to be
controlled,
3. followed by <ENTER>.
Upon accepting the SYS command, the switch with the corresponding address will illum inate the “IR” L ED in gree n for visual
indication and respond to all IR Remote commands. All other units will illuminate in red and ignore any further commands.
Note: To prepare to send a command to all SPLITMUXs at the same time (all SPLITMUXs would have to b e within
line-of-sight of the IRT-UNV), press <SYS> then <0> then <ENTER>. Pressing <0> tells the Remote to send the
command to all addresses. The PWR/STANDY LED on each SPLITMUX will illuminate and remain green to indicate
readiness to receive commands.

EXAMPLE OF CASCADED CONFIGURATION
In the example below, 4 SPLITMUXs are connected in a cascaded configuration.
IP
IP
Figure 74- View of cascaded configuration from Master
The Custom Mode Settings page provides a view of the combined custom mode
settings of the configuration. Dotted lines indicate input layouts of slave units
connected. In order to make edits to the configuration of slave units, either change
the IP address in the URL bar or double-click on the channel where slave units are
indicated.
In Cascade Settings (image right), the slave connected to Input 3 is indicated. All other
connections are direct, including the Output since on this SPLITMUX the output is
connected to the display.
In this case, double-click on channel 3 to switch to the configuration of the SPLITMUX
at IP 192.168.3.173.
IP
IP
Note: When cascading SPLITMUXs,
make sure the Output Settings of all
slaves are set at or below
1920x1080p. The Input of the
Master does not support higher
resolution settings from the slave
units.
To reduce cost, we recommend
using the SPLITMUX-HD-4RT for any
units connected as Slaves in a
cascaded configuration.

Figure 75- View of cascaded configuration from Slave at IP 192.168.3.173
When looking at a slave unit, the hierarchy will be indicated at the upper left of the layout choices. The leftmost tab is the master,
followed by the nearest connected slave. In Figure 73, it is indicated that two levels of SPLITMUXs are connected through
channel 2 (Input 2). These are, of course, IP 192.168.3.125 and IP 192.168.3. 183.
Any edits made using the web interface configuration menu at this level will directly and only impact the SPLITMUX at IP
192.168.3.173.
To switch back to the configuration of the master, click on the tab labeled “192.168.3.145”.
To switch to the next slave in the configuration (IP 192.168.3.125), double-click on channel 2.

Page 77
SPLITMUX Quad Screen 4K Multiviewer
In Figure 77, it is indicated that one level of SPLITMUX is connected through channel 2 (Input 2). This is IP 192.168.3.183.
Notice that in Cascade Settings the slave (192.168.3.183) is configured for connection to Input 2, and the upstream slave
(192.168.3.173) is connected to the output. Other input ports are configured for direct connection to input sources.
Any edits made using the web interface configuration menu at this level will directly and only impact the SPLITMUX at IP
192.168.3.125.
To switch to the last slave in that configuration (IP 192.168.3.183), double-click on channel 2.
To switch back to the configuration of the master or upper level slave, click on the appropriate tab.
tabs showing hierarchy of configuration
Figure 77- View of custom configuration of Slave at IP 192.168.3.183
In Figure 78, we see that there are no slaves connected to this SPLITMUX. In Cascade Settings, only the output master IP
address is configured.
At each configuration level, the Current Mode setting will dictate what is viewed upstream at the output, regardless of how the
custom layout is configured. The custom layout will only impact what is viewed if the Current Mode is set to “Custom” (page 17).
The audio is impacted in the same fashion. If the audio from an input on the lowest-level slave is desired, the configured in put
channel for each higher level slave must be set to pass that audio signal, all the way through to the master.
