IR Control
IR Remote Control
The matrix switcher has a built-in IR sensor on the front panel for receiving IR control signal from IR remote. In addition, it also provides IR EYE port on the rear panel to connect an external IR receiver for IR local control.
The matrix switcher can be controlled by the below IR Remote:
- Enter/exit standby mode.
- Blinking red when a button is pressed.
- Video source selection buttons.
- Output channel selection buttons.
- Menu buttons:
- ALL: Select all inputs or all outputs.
- EDID: Enable one or several input sources to manually capture and learn the EDID data of output device.
- CLEAR: Cancel the current operation, if ENTER has not been pressed.
- ENTER: Confirm the desired operation.

Note: The IR receivers which are connected to HDBaseT receivers also can receive the IR signal of the IR remote, so the matrix switcher also can be controlled by the IR remote at the far-end HDBaseT receivers’ position. The IR remote-control mode can be enabled or disabled by sending RS232 command “IRRCM[XX]ON.”/ “IRRCM[xx]OFF.” ([XX]=00~04). Please refer to the 8.3.1 System Control for more details.
IR Pass-through Control
The matrix switcher supports bi-directional IR pass-through, allowing the devices to be controlled by both source and destination ends. This section provides connection and switching examples to illustrate possible configurations.
Control Local Input Device from Remote
The same basic principle applies when controlling the local input device from the remote location.
- Control local input device through IR OUT port
Example: Switch HDMI input 3 to HDBaseT output 4.
Connect an IR receiver to IR IN port on the receiver, then connect an IR emitter to the IR OUT 3 on the matrix switcher. The third input source can be controlled through its corresponding IR output port. The connection diagram shown as below:
- Control local input device through IR ALL OUT port
The emitter can be connected to the IR ALL OUT port on matrix switcher to control all local input devices. In this case, the IR receiver must be connected to the IR IN port on each connected HDBaseT receiver, as shown in the diagram below:

RS232 Control Connection
Control the Matrix Switcher from Local
To control the matrix switcher from a local PC, the 3-pin to DB9 RS232 Cable is used to connect between the matrix and PC. The connection diagram is shown as below:
Control the Matrix Switcher from Remote
To control the matrix switcher from remote location, please connect one or more PCs to the RS232 ports of HDBaseT receivers with the 3-pin to DB9 RS232 Cables. The matrix switcher can be controlled by any one of PCs, the connection diagram is shown as below:
Note: The command RS232RCM[XX]ON. ([XX]=00~04) needs to be sent to enable or disable this control mode. For example, send the command RS232RCM00ON. to enable the remote-control mode for all HDBaseT outputs, and send the command RS232RCM00OFF. to disable the remote-control mode for all HDBaseT outputs. Please refer to the 8.3.1 System Control for more details.
Control the Remote Third-party Device from Local
To control a third-party device from local, first determine which HDBaseT receiver is connected to (1 in the diagram below). Next, connect a PC to the corresponding RS232 port of matrix switcher with 3-pin to DB9 RS232 Cable, then connect a third-party device (e.g. projector) to the RS232 port of the determined HDBaseT receiver. The remote third-party device can be controlled by the local PC, the connection diagram is shown as below:

The next pop-up window can also be closed with "Continue". An empty project is enough to send and receive commands easily (The default setting is always “Start with a blank project / blank script “)
Now you are in the main view, where commands are sent and feedback is received.
The next step is to select the correct COM port of the PC. To do this, double-click on "COM1" in the corresponding setup window.
Click “Continue” to close this window.

In the following window, select the drop-down menu labeled "Send / Receive on Comm Channel", select the appropriate COM port and then click on "OK" at the bottom right corner.
All other settings can be left at default for most applications, but refer to device RS232 settings to be sure.
Double click on “COM1” to change to the right COM port.

In order to be able to send commands, open communication with the device by clicking on "Play". (1)
Then the keyboard function must be activated, so that commands can be written in the "communication window". (2)
Finally enter the command, for example "50701%". This is then confirmed by pressing "Enter" to send. Any response from the connected device will appear in red. (3)
Select the right COM port.

Click “Play” to open the communication.
Enable the keyboard type in function.

RS232 Communication Commands
When controlling the matrix, the serial port settings for all RS232 commands is:
Baud rate: 9600 Data bit: 8 Stop bit: 1 Parity bit: none
The matrix switcher can be controlled by sending the following RS232 commands:
Note: Please remember to end the commands with the ending symbols “.” or “;”.Type the command carefully, it is case-sensitive.All commands ended without “<CR><LF>”.

Firmware Upgrade
- Prepare the latest two upgrade files and rename them as 08010000.APP and 08010000.APS on PC.
- Power off the switcher, and connect the FW port of switcher to the PC with USB cable.
- Power on the switcher, and then the PC will automatically detect a U-disk named of BOOTDISK .
- Double-click the U-disk, a file named of READY.TXT would be showed.
- Directly copy one of two upgrade files (e.g. 08010000.APP ) to the BOOTDISK U-disk.
- Reopen the U-disk to check the filename READY.TXT whether automatically becomes SUCCESS.TXT , if yes, the firmware was updated successfully, otherwise, the firmware updating is fail, the name of upgrade file should be confirm again, and then follow the above steps to update again.
- Repeat step 5~6 to copy the other upgrade file ( 08010000.APS ) to the BOOTDISK U-disk.
- Remove the USB cable after firmware upgrade.
- After firmware upgrade, the switcher should be restored to factory default by sending command.
