1. Introduction
1.1 Introduction to SUH4 1x4 HDBT splitter
SUH4 is an HDBT Splitter accepting 1 HDMI input and distributing to 4 HDBT outputs,
plus 1 HDMI local output. The HDMI output socket can be used to monitor local devices
or cascade with additional splitter.
SUH4 allows uncompressed 4K (max) HDMI, IR, and RS232 signals to be transmitted
over a single CAT5e/6/7 cable. It supports transmission of 4k signal up to 40m and
1080p signal up to 60m. If required, use the HDMI local output to cascade the HDMI
signal up to 4 times with additional SUH4. SUH4 is also capable of bi-directional IR
control, RS232 control, EDID management and PoC.
HDMI Twisted Pair PoC Receiver is recommended to utilize the full function of the HDBT
outputs of this device.

3.2 System Diagram
3.3 Connection Procedure
Step1.Connect a HDMI source device (e.g. Blue-ray DVD) to the HDMI INPUT socket
of SUH4 with HDMI cable.
Step2.Connect a HDMI display to HDMI OUTPUT socket of SUH4 with HDMI cable.

Step3.Connect HDMI Twisted Pair PoC Receiver(s) to HDBT output port(s) of SUH4
with twisted pair.
Step4.Connect control device (e.g. PC) to the RS232 IN port of SUH4.
If you want to cascade RS232 signal among several SUH4 through RS232 LOOP,
connect the RS232 LOOP socket of one of them and the RS232 IN socket of the
next until all SUH4 have been connected.
Step5.Connect an IR Receiver to the IR IN port, and an IR Emitter to the IR OUT port.
The IR signal can be transmitted bi-directionally between SUH4 and HDMI
Twisted Pair PoC Receiver(s).
If you want to cascade IR signal among several SUH4, connect the IR LOOP
socket of one of them and the IR IN socket of the next until all SUH4 have been
connected.
Step6.Connect a DC 24V power adapter to the power port of SUH4, HDMI Twisted Pair
PoC Receiver is able to be energized by SUH4 with PoC solution.
3.4 Cascade Connection
3.4.1 Cascade AV Signal
HDMI source signal can be cascaded to several displayers via HDMI OUT/ IN.
Connect the HDMI OUT socket of the first SUH4 to HDMI IN socket of the next until all
SUH4 have been connected.
HDMI signals delivered within the first SUH4 are able to be outputted to other connected
SUH4 too.
3.4.2 Cascade Control Signal
SUH4 supports control cascading via IR LOOP/ RS232 LOOP to enable signal loop
output. Users can choose one or multiple cascade methods according to their specified
needs.
Here is the cascade connection diagram:

4K HDBT Splitter 1x4 with PoC

Cascade through IR Loop
Connect the IR LOOP socket of the first SUH4 and the IR IN socket of the next
until all SUH4 have been connected.
Sending IR signals to the IR Receiver connected to the first SUH4 will control all
cascaded SUH4.
Cascade through RS232 Loop
Connect the RS232 LOOP socket of the first SUH4 and the RS232 IN socket of the
next until all SUH4 have been connected.
Sending RS232 commands will control all cascaded SUH4 synchronously.
Note: To identify SUH4 in cascading, please set a unique ID for each unit when the
cascade connection is done.
3.5 Twisted Pair Cable Connection
The twisted pair used in HDMI Twisted Pair PoC Receiver MUST be a straight-through
cable. The connectors can be T568A or T568B, but both sides must be the same.
