transmission distance up to 60m. Meanwhile, the ports support PoC. Connect the HDBT
output port of HDBaseT 8x8 matrix switcher to HDMI Twisted Pair PoC Receiver with
twisted pair. As the port supports PoC, once powered the HDBaseT 8x8 matrix switcher,
the HDMI Twisted Pair PoC Receiver will be energized synchronously, which allows the
two devices energized with the same adapter.
3.5 Connection with RS232 Communication Port
Except the front control panel, the HDBaseT 8x8 matrix switcher can be controlled by
far-end control system through the RS232 communication port. This RS232
communication port is a female 9-pin D connector. The definition of its pins is listed in
the table below.

3.7 Connection Procedure
1) Connect HDMI sources (e.g. DVD) to HDMI inputs of the HDBaseT 8x8 matrix
switcher with HDMI cables.
2) Connect HDMI displayers (e.g. HDTV) to HDMI outputs of the HDBaseT 8x8 matrix
switcher with HDMI cables.
3) Connect speakers/earphones to AUDIO output ports (3-pin captive screw
connectors).
4) Connect the HDBaseT port of HDBaseT receiver and the HDBaseT 8x8 matrix
switcher with twisted pair.
5) Connect the RS232 port (9 pin female D) of the HDBaseT 8x8 matrix switcher with
control device, e.g. a PC.
6) Connect the RS232 port of controlled device to any RS232 port (3-pin captive screw
connector) of the HDBaseT 8x8 matrix switcher. The control signal can be
transmitted bi-directionally.
7) The HDBaseT 8x8 matrix switcher can be controlled by its built-in IR receiver or
through the IR EYE port by connecting with external IR receiver. The IR signal can
also be transmitted bi-directionally (connect IR OUT port of the HDBaseT 8x8 matrix
switcher to IR IN port of a far-end IR device, and connect IR IN ports of the HDBaseT
8x8 matrix switcher to IR OUT port of the far-end IR device), and in this mode, we
can control the HDBaseT 8x8 matrix switcher remotely.
Note: The IR IN port has built-in infrared carrier receiver.

4. System Operations
4.1 Front Panel Button Control
The operation examples are showed in 2.1 Front Panel. Here we make a brief
introduction to the system inquiry operations.
4.1.1 I/O channel control
1) To convert an input to an output:
Operation: “input”+“output”+“ENTER”
Example: input 1 to output 2
Note: In default status, 8 IR OUTs correspond with 8 HDMI INPUTS. When you convert
an HDMI input to an output, the corresponding IR OUT will be switched synchronously.
2) To convert an input to several outputs:
Operation: “input” + “output” + “output” +… + “ENTER”
Example: Switch input 2 to output 2, 4, 7
3) To convert an input to all outputs:
Operation: “input” + “ALL” + “ENTER”
Example: Convert input 1 to all outputs
Note: Indicators of the pressed buttons will blink green for three times if the conversion
is done, then it will be off. If the conversion failed, they will be off immediately.
4.1.2 EDID Data Learning
One input port learns the EDID data of one output port
Operation: Press “EDID”, “INPUTS”+“OUTPUTS”+“ENTER”.
Example: Input 2 learns EDID data from output 4

HDBaseT 8x8 Matrix Switcher
9
All input ports learn EDID data from one output port
Operation: Press “EDID”, “ALL”+“OUTPUTS”+“ENTER”
Example: All input ports learn EDID data from output 4
Note: Indicators of the pressed buttons will blink green for three times if the conversion
is done, then it will be off. If the conversion failed, they will be off immediately.
4.1.3 EDID Setting
There are four types of embedded EDID data (shown as below). Select one type of
EDID data in EDID setting status.
OUTPUT 1: 1080P 2D PCM2.0
OUTPUT 2: 1080P 3D 5.1
OUTPUT 3: 1080P 2D PCM2.0
OUTPUT 4: 1080P 2D 5.1
Set EDID data for one input port
Operation: Press “EDID”(hold for 3 seconds to enter in EDID setting status),
“INPUTS”+“OUTPUTS”+“ENTER”.
Example: Set the EDID data of INPUT 4 to the forth type of embedded EDID data:
Press (hold for 3 seconds) .
Set EDID data for all input ports
Operation: Press “EDID”(hold for 3 seconds to enter in EDID setting status),
“ALL”+“OUTPUTS”+“ENTER”.
Example: Set the EDID data of all input ports to the second type of EDID data:
Press (hold for three seconds) .
Note: Indicators of the pressed buttons will blink green for three times if the conversion

the matrix will return to the previous status.
4.2 IR Control
By using IR & HDBaseT transmission technology, the HDBaseT 8x8 matrix switcher has
some functions as follows:
1) Control far-end output device from local.
2) Control local input/output device remotely.
3) Control the HDBaseT 8x8 matrix switcher locally/remotely.
4.2.1 Usage of IR Remote
①Standby button, press it to enter/ exit standby
mode
②Input channels, range from 1~8,
corresponding IR signal switched
synchronously when switching input
channels.
③Menu buttons, ALL, EDID and CLEAR
buttons have the same function as the front
panel buttons. Please refer to 4.1 Front Panel
Button Control for details.
④: Navigation buttons.
ENTER: Confirm button.
⑤Output channels, range from 1~8.
Each channel has 1 IR IN, 1 HDMI, 1
HDBaseT, 1 RS232, and 1 AUDIO outputs,
and channel 5~8 are without HDMI outputs.
Note: With this IR remote, HDBaseT 8x8 Matrix Swithcer can be controlled by the
built-in IR, the extended IR receiver connected to the “IR EYE”and the IR receiver on
the far-end receiver.
4.2.2 IR Operations
1) IR Matrix Switching

HDBaseT 8x8 Matrix Switcher
12
The 8 “IR OUT”ports and the 8 “IR IN”ports on the far-end receivers make up an 8x8 IR
matrix. See as below:
Control Local Devices or the HDBaseT 8x8 Matrix Switcher Remotely
The IR signal is sent by corresponding IR remote, then it is transferred to HDBaseT
receiver, then to corresponding zone of the matrix through the twisted pair, finally it is
transferred to IR OUT port and received by controlled device.
Switching Operation: (8 IR IN ports correspond to 8 HDMI input ports separately in
default mode.)
a) Sending command (reference to 4.3 RS232 Control): [x1]R[x2].
x1: Corresponding to the 8 IR OUT ports of the matrix, the IR transmitter connected
to this port can be placed at IR receiving area of output device or HDBaseT 8x8
Matrix Switcher itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN
port connects with IR receiver) number of HDBaseT 8x8 Matrix Switcher.
Example: Send command “3R2.”to transfer IR signal received from zone 2 to IR
OUT port 3.
Note: When switch all the 8 IR input signal channels to the same IR out channel, it is
not able to control the 8 far-end IR receivers at the same time.
2) IR Carrier Enforcing
Factory Default:
a) Only if the IR receiver connected with HDBaseT receiver is with IR carrier, can the
received IR signal be transferred to IR OUT port of the matrix.
b) Only if the IR receiver connected with IR ALL IN port of the matrix is with IR carrier,
can the received IR signal be transferred to IR OUT port of the matrix.

HDBaseT 8x8 Matrix Switcher
13
If the IR receiver connected with HDBaseT receiver or IR ALL IN port of the matrix is
not with IR carrier, send the command “%0901.”to enter infrared carrier enforcing
mode, and then IR signal can be transferred to IR OUT port.
3) IR control setting
Control far-end output device from local
Connect an IR receiver with IR carrier to the IR IN port of HDBASET 8X8 MATRIX
SWITCHER, users can control far-end output displayer via its IR remote from local.
In that case, the IR signal is transferred via twisted pair. Only the corresponding IR OUT
port can emit control signals to the remote displayer.
See the figure below:
Control far-end device from Local
Note: The IR receiver connected to IR IN must be with IR carrier
The IR signal received from IRALL IN port will be transmitted to all the eight far-end
HDBaseT receivers connected to HDBaseT ports of the HDBASET 8X8 MATRIX
SWITCHER. See as below:

HDBaseT 8x8 Matrix Switcher
14
Control far-end device through IR ALL IN port
Control local device from remote
User can control local source devices with their IR remote from remote too. When using,
the IR signal received by the HDBaseT receiver will be transmitted to the corresponding
IR OUT port of the HDBASET 8X8 MATRIX SWITCHER. See below:
Control local device from remote

HDBaseT 8x8 Matrix Switcher
15
Controlled by a Third-party IR Control Device
Connect the 3-pin end of the included IR converting cable (see as below) to IR IN port of
the HDBaseT 8x8 matrix switcher, and plug the 2-pin end to IR OUT port of the
third-party control device. Then the IR signal received by the third-party control device is
able to be transmitted via the twisted pair, and finally gets to the remote displayer.
IR converting cable
4.3 RS232 Control
4.3.1 RS232 Commands
Through the RS232 communication port, users can control a far-end device whose
bound rate is 2400, 4800, 9600, 19200, 38400, 57600 or 115200. Default settings of the
HDBaseT 8x8 matrix switcher: bound rate is 9600, data bit is 8, stop bit is 1 and parity
bit is none.
