3.3 Connection Procedure
Step1. Connect a HDMI source device (e.g. Blue-ray DVD) to the HDMI INPUT socket
of HDBaseT Splitter with HDMI cable.
Step2. Connect a HDMI display to HDMI OUTPUT socket of HDBaseT Splitter with
HDMI cable.
Step3. Connect HDMI Twisted Pair PoC Receiver(s) to HDBaseT output port(s) of
HDBaseT Splitter with twisted pair.
Step4. Connect control device (e.g. PC) to the RS232 IN port of HDBaseT Splitter or
HDMI Twisted Pair PoC Receiver (bi-directional RS232 control, either end is
available).
If you want to cascade RS232 signal among several HDBaseT Splitters through
RS232 LOOP, connect the RS232 LOOP socket of one of them and the RS232
IN socket of the next until all HDBaseT Splitters 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 HDBaseT Splitter and
HDMI Twisted Pair PoC Receiver(s).
If you want to cascade IR signal among several HDBaseT Splitters, connect the

SP-HDBT1X4
6
IR LOOP socket of one of them and the IR IN socket of the next until all
HDBaseT Splitters have been connected.
Step6. Connect a DC 24V power adapter to the power port of HDBaseT Splitter;
HDBaseT Splitter can supply power to the HDMI Twisted Pair PoE Receiver with
PoE 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 HDBaseT Splitter to HDMI IN socket of the
next until all HDBaseT Splitter have been connected.
HDMI signals delivered within the first HDBaseT Splitter can be outputted to other
connected HDBaseT Splitter too.
3.4.2 Cascade Control Signal
HDBaseT Splitter 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:
