RGBSplit
The RGBSplit allows the output of
RGB computer video to be seen on
up to 4 monitors simultaneously
depending on the splitter
purchased. Each monitor can be
located up to 250 feet (76.2 m)
away from the splitter.
The splitter unit is supplied with
the following components:

Installation
1. Locate your RGBSplit close to the
computer.
2. Connect coaxial cable from the
monitor output of your computer to
the RED, GREEN, and BLUE input
connectors of the RGBSplit.
Depending on your computer and
monitor type, you may also need to
connect coaxial cables from the
computer to the input connectors
marked H/CS (Horizontal/Com-
posite Sync) and/or V (Vertical
Sync).
3. If you are using an adapter cable,
connect that adapter on the input
and/or output as necessary for the
computer type you are using.
4. Connect the monitor(s) to the
RED, GREEN, BLUE, H/CS, and/or
V outputs on the rear your RGBSplit.
Monitor extension cables
(EYNRGBS2) may be used to extend
the distance from the RGBSplit up
to 250 feet (76.2 m).
5. Plug the 9-VDC wall power
transformer into the jack on the rear
of your RGBSplit marked POWER.
6. Plug the power transformer into
a 110-VAC or 220-VAC wall outlet as
appropriate. The front-panel LED
should glow red to indicate that the
unit is properly powered.
7. Turn on the computer and the
monitor(s). The monitor(s) will
now display the computer’s output.

RGBSplit
The RGBSplit requires no ongoing
adjustments once it is installed. It’s
designed to work continuously and
can be placed “out of sight” if
desired. The RGBSplit is designed to
drive multiple monitors and provide
a reliable means of extending the
viewing position of RGB monitors.
Additionally, each monitor output is
independently buffered. This
ensures isolation and proper signal
levels—regardless of the number of
monitors you use.
The splitters may be cascaded to
achieve multiple outputs at different
distance from the computer. The
maximum distance that a monitor
can be placed from your computer
when cascading will depend upon
your pixel format.
Please note that the plug-in
transformer will feel warm after
RGBSplit is on for a period of time.
This is normal. The RGBSplit draws
a significant amount of power.
If one or two colors are missing on
one of the RGB monitors, make sure
all connections to the RGBSplit are
secure. Make sure the monitor’s
BNC connectors are tightened.
