1. Operation instruction

3.1 Communication protocol

1,In order to increase its subsequent extensibility, the version V001 of the control protocol is the mainstream ASCII control mode. The follow-up needs to add protocols and add relevant protocols to the control board to support parsing.And version number (V002~V999) in the communication is the default of version number V001. When the serial port receives the ASCII code Change the Protocol to Version VXXX, where the semicolon is the end of the command (the sign must be input in English), XXX is actually used in the 3 bit digit.The following example is to use a 004 version protocol to communicate: Change the Protocol to Version V004;

2,The RS-232 communication uses the baud rate 9600, the data bit 8, the stop bit 1, and no checkout bit.

3. System instruction: (end with hexadecimal 3B.If you need to convert all hexadecimal, please see Appendix -I: Standard ASCII code)

2. Please change the cable with good quality;

3. Adjust the color balance of the display equipment with reference to the instructions.

5.4, The cause of a jitter or a points:

1. Causing great loss of signal since the cable is too long;

2. Equipment instability or wire damage in the input signal;

3. The power’s ground wire is not connected well so that the signal interference appears.


1.It is suggested that using the signal extender to ensure the minimum line loss.;

2. Debug the definition of input signal and use high quality wire;

3. It is suggested that all the equipment be connected to the same earth wire.

5.5, Reasons that the picture is not full, and with a black edge:

1. Your display device has a back end removal of the signal;

2. You have adjusted the position of the image too much by controlling the software.


1. According to the instructions of the display device, you can settle the default settings in the software.
