MOUNTING
The SPLITMUX-HD-4RT can be purchased in a 1RU case with parts and hardware for mounting in a rack as a single unit
(SPLITMUX-HD-4RT-R) or as a dual unit (SPLITMUX-HD-4RT-2R). 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

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.
¾When FULL is pressed, the input selected using buttons 1 through 4 (or “active” image) will be the only image on
the display.
¾When QUAD is pressed, images from all 4 inputs will be displayed equally on the monitor.
¾When 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.
¾When CUSTOM is pressed, the images will be displayed in whatever way you have the SPLITMUX configured 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 maximum resolution.

In QUAD screen mode, all four video sources share the screen
equally. Each video source is displayed completely.
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.
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.

Reset Resolution
In the event an incompatible resolution setting is applied to the SPLITMUX, to quickly restore the images of video sources to the
SPLITMUX, press the PIP and CUSTOM buttons at the same time. This will reset the output to the default resolution of
640x480 @60Hz.
