EDID management button: Enable input port to
manually capture and learn the EDID data of output
devices.
CLEAR: Withdraw an operation like switching output
channel, learning EDID data before it comes into

By using IR pass-through & HDBaseT transmission technology, the 4K HDBaseT
Matrix Switcher has some functions as follows:
Control far-end display.
Control local source device.
Control far-end display
Connect an IR receiver with IR carrier to the IR IN port of the 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 display.
See the figure below:
Note: The IR receiver connected to IR IN must be with IR carrier

Control local source device.
Connect IR receiver(s) to IR IN on far-end HDBT receiver(s), and IR Emitter(s) to IR
OUT port of the switcher, and use the IR Remote of local source to control the
device remotely.
1 to 1:
Connect an IR receiver to IR IN on far-end HDBT receiver, and an IR Emitter to IR
OUT port of the switcher. Use the IR Remote of local source to control the device
remotely. See below:
Note: Send command “%0901.” to enter infrared carrier enforcing mode if the IR
Receiver connected to IR IN of the receiver is not with carrier.

Multiple to Multiple: (IR Matrix):
The 8 “IR OUT” ports and the 7 “IR IN” ports on the far-end receivers make up a 7 x
8 IR matrix. See as below:
The IR signal is sent by 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:
Sending command:[x1]R[x2].
x1: Corresponding to the 8 IR OUT ports of the Matrix Switcher, the IR transmitter
connected to this port can be placed at IR receiving area of output device or the
Matrix Switcher itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR
IN port connects with IR receiver) number of the Matrix Switcher.
→ Example: Send command “3R2.” to transfer IR signal received from zone 2 to IR
OUT port 3.

To convert one input to an output
Example: Input 1 to Output 3
→Press INPUTS 1 + OUTPUTS 3
Note: Default status, on first boot up this matrix assigns the IR outputs to the
corresponding HDMI input, meaning, IR out 1 is directly associated to HDMI input 1
and so on. When you switch an HDMI input to a different output, the corresponding
IR OUT will be switched synchronously to allow the IR commands to be sent from
the select zone back through the Matrix Switcher to the source.
To convert an input to several outputs
Example: Convert Input 2 to Output 3, 4 and 5
→ Press INPUTS 2 + OUTPUTS 3 + OUTPUTS 4 + OUTPUTS 5
To convert an input to all outputs
Example: Input 1 to all Outputs
→Press INPUTS 1 + ALL + ENTER
SIGNAL SWITCHING
11

RS232 Connection
Except the front control panel, the Matrix Switcher can be controlled by far-end
control system through the RS232 communication port. This RS232 communication
port is a 3-pin phoenix connector. User can use the RS232 cable (Phoenix to 9-pin
D-Sub) to connect the RS232 port to PC, see as below:
RS232 Control Software
Installation: Copy the control software file to the computer connected with the
Matrix Switcher.
Uninstallation: Delete all the control software files in corresponding file path.
Basic Settings
Firstly, connect the Matrix Switcher 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
