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 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:

SP-HDBT1X4

"Cascade through IR Loop
Connect the IR LOOP socket of the first HDBaseT Splitter and the IR IN socket of
the next until all HDBaseT Splitter have been connected.
Sending IR signals to the IR Receiver connected to the first HDBaseT Splitter will
control all cascaded HDBaseT Splitter.
"Cascade through RS232 Loop
Connect the RS232 LOOP socket of the first HDBaseT Splitter and the RS232 IN
socket of the next until all HDBaseT Splitter have been connected.
Sending RS232 commands will control all cascaded HDBaseT Splitter
synchronously.
Note: To identify HDBaseT Splitter 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 Twisted Pair PoC Receiver MUST is a straight-through cable.
The connectors can be T568A or T568B, but both sides must be the same.
4. Control Modes
HDBaseT Splitter has a good application in various occasions, such as computer realm,
monitoring, conference room, big screen displaying, television education, command &
control center and smart home etc.
HDBaseT Splitter can be controlled via IR, RS232 commands and EDID management.
4.1 IR Control
HDBaseT Splitter provides with an IR IN port. Connect an IR receiver to the IR IN port,
users can control HDBaseT Splitter/ far-end device from local or control local devices
from remote via corresponding IR remote.

4.2 RS232 Control
As RS232 can be transmitted bi-directionally between HDBaseT Splitter and Twisted
Pair PoC Receiver, so it is able to control a third party RS232 device from local or
control HDBaseT Splitter from remote. When to control a third party RS232 device, the
baud rate of this device should be 9600.
4.2.1 Installation/uninstallation of RS232 Control Software
!Installation Copy the control software file to the computer connected with HDBaseT
Splitter.
!Uninstallation Delete all the control software files in corresponding file path.
4.2.2 Basic Settings
Firstly, connect HDBaseT Splitter with an input device and an output device. Then,
connect it with a computer, which is installed with RS232 control software. Double-click
the software icon to run this software.
Here we take the software CommWatch.exe as example. The icon is showed as below:
The interface of the control software is showed as below:

SP-HDBT1X4

Please set the parameters of COM number, bound rate, data bit, stop bit and the parity
bit correctly, and then you are able to send command in Command Sending Area.
Command format: ID +Port number +RS232 command.
Of which port number stands for the HDBT port that the device to be controlled is
connected to, the value varies from 1~4.
For example, if the ID of the HDBaseT Splitter is 01, and the device to be controlled is
connected to HDBT port 2, then send the command “1B1.” as “0121B1.”.
Parameter Configuration area
Monitoring area indicates if the
command sent works.

Note: To control HDBaseT Splitter via RS232 port, the communication protocol
parameters should be configured in the right manner: Baud rate: 9600; Data bit: 8; Stop
bit: 1; Parity bit: none.
4.2.3 Control far-end device from local
Connect the RS232 ports of HDBaseT Splitter and Twisted Pair PoC Receiver (See
Figure 4-3), and then it is capable to control HDBaseT Splitter and far-end device from
local by sending RS232 commands.
Figure 4- 3 Control far-end device from local
4.2.4 Control local device from remote
Connect the RS232 ports of HDBaseT Splitter and Twisted Pair PoC Receiver (See
Figure 4-4), and then it is capable to control HDBaseT Splitter or local displayer from
remote by sending RS232 commands.
