In the low-bit display state, four LEDs of 1/2/4/8 represent low ID value 1-15. ID value is the total of what is light on. Refer to the following table for details.
If 15 IDs are not enough for your circumstances, up to 255 IDs are provided. The ID more than 15 is “high bits x 16 + low bits”.In the high-bit display state, it is divided into 16 segments with 16 IDs as a segment. At this point, 1/2/4/8 four LEDs represent the number of segments. Refer to the following table for details.

How to control the device by using remote control

Using the infrared transmission function of this product, you can remote control the source devices and other peripherals that can be controlled by infrared (e.g. air conditioner).
Connect the IR Transmitter cable to the IR OUT jack of TX, and aim the IR probe in front of the IR sensor of the video source. (Please find the correct position of IR sensor of the video source or the IR signal won’t pass through)
Connect the IR Receiver cable to the IR IN jack of RX, and use the source device remote control aiming at IR receiver of the cable to control the source device, the distance between this IR receiver hole and remote control should be within 5m.

How to control the device by using mouse/keyboard

Connect the Device Port of TX to PC/ Android TV Box by using a Micro USB-USB Type A Cable.
Connect the RX USB Host jack with a mouse or keyboard. After the device is identified, there will be an OSD character showing “HID Driver Loading”, and a mouse icon will be displayed at the top of the standby screen.
Then you can use the mouse or keyboard to control the PC/ game controller in other room.

RS232 communication through
