CHAPTER 2: OVERVIEW
2.1 INTRODUCTION
The HDBaseT Video Splitter, 1 x 4, 4K UHD, Smart EDID accepts a single HDMI input and splits it into four HDBaseT outputs. The splitter
is designed with an HDMI loop out, which is intended to cascade to additional units. It supports video resolutions up to 4K@60Hz and all
HDMI audio formats. It can extend 1080p signals on each output to a distance up to 229 feet (70 meters) and 4K signals to a distance up
to 131 feet (40 meters) over a single CATx Ethernet cable. It supports the Power over HDBaseT (PoH) feature, which allows the compatible
receivers to be powered from the splitter over the Ethernet cables. It supports bidirectional IR and RS-232 pass-through and loop output.
2.2 FEATURES

• HDMI: HDMI loop output port for connecting a local display.
• HDBT 1–4: Four HDBaseT RJ-45 jacks with PoH support for connecting four HDBaseT
receivers.
• IR IN: Four 3.5-mm IR input jacks for connecting the four IR receivers.
3 IR Control
• IR ALL IN/LOOP IN: 3.5-mm IR jack for connecting an IR receiver or cascading to a
previous device
• IR OUT: 3.5-mm IR jack for connecting an IR emitter
• IR LOOP OUT: 3.5-mm IR LOOP output jack for cascading to next device
4 RS-232 Control
• RS-232 IN: 3-pin RS-232 connector. Connect to the PC using a 3-pin to DB9 cable.
• RS-232 OUT: If cascading multiple units, use the 3-pin to 3-pin cable to connect the
output to the RS-232 IN on the next device in the chain.
5 ID Preset
Assigns a single digit ID to the splitter when cascading multiple splitters and using RS-232
control, each splitter must have a unique ID. Use a small, flat-head screwdriver to set the
ID. There are sixteen positions, with 0 at the fully counterclockwise position and F at the
fully clockwise position. After setting the ID, the device must be restarted for the new ID to
take effect.

CHAPTER 4: IR CONTROL
The IR receivers and emitters can be connected to the system to allow for IR control of remote devices. The bidirectional IR feature
provides the two-way control either for the source or display device(s). Use the following sample connection diagrams to connect
for IR remote control.
4.1 CONTROLLING THE DISPLAY DEVICE BY IR IN
The four IR IN ports of the splitter can receive IR signals from remotes to send to control displays. Connect four IR receivers to IR IN ports
of the splitter, and then connect four IR emitters to IR OUT ports on HDBaseT receivers.
