1. Product Introduction
This device accepts a single HDMI input and splits it into one HDMI and four HDBaseT
outputs. The splitter is designed with an IR loop out and loop in which are intended to
cascade to additional units. It supports video resolutions up to 4K@60Hz 4:4:4 8bit and
all HDMI audio formats. It can extend 1080p signals on each output to a maximum
distance of 229 feet (70 meters) and 4K signals to a maximum distance of 131 feet (40
meters) over a single CATx Ethernet cable. It supports Power over HDBaseT (PoH)
feature, which allows the receivers to be powered from the splitter over the Ethernet
cables. It supports bidirectional IR pass-through and IR, RS232 cascade control.
1.1 Features

Distribute one UHD/ 4K HDMI signal to four HDBaseT outputs and one loop HDMI
output.
Supports cascade connection, distribute video signal to multiple video displays.
Maximum transmission distance is up to 40m for 4K, and 70m for 1080p.
Supports video resolution down-scaling, 4K input can be automatically down scaled
to 1080 output.
Supports audio de-embedding.
Each HDBaseT output supports IR pass-through.
Supports RS232 and IR cascade control.
Supports 24V PoH, the HDBaseT receiver can be powered by the HDBaseT splitter.

5. 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 connection diagrams as an example for
IR remote control.
5.1 Controlling the Display Device by IR IN
The four IR IN ports of the splitter can receive IR signals from remote controllers 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.

6. RS232 Control
The splitter and compatible receivers feature RS232 ports to transmit RS232 signals
from computer to control far-end third-party devices by using 3-pin to DB9 cables and a
3rd party RS232 control software. After installing the RS232 control software, please set
the parameters of COM port number, baud rate, data bit, stop bit and parity correctly.
Compatible receivers must be able to communicate at 2400, 4800, 9600, 19200,
38400, 57600, or 115200 baud rates. The splitter requires the following communication
protocol parameters:
Baud rate: 9600 (default)
Data bit: 8
Stop bit: 1
Parity bit: none
RS232 Commands
The following commands requires both the “Carriage Return” and “Line Feed” control
characters at the end of the command line: “<CR><LF>”.
