Reset to default configuration
3、Serial port instructions
The serial port version of these products can set all basic setting 、light and volume、decode function、
communication mode 、prefix and suffix and so on by serial port instructions.
Serial port instructions format: command + check bit
Remark 1: Check bit is the last two bits at the back of the instructions, computation rule: sum all byte,
then perform NOT(negation) and plus “1”
For example, Reset to default configuration 08+C6+04+08+00+F2+FF+00=2CB
Perform NOT(negation) is FD34, plus 1 is FD35
Remark 2: only a few instructions need to count the check bit, like prefix and suffix. Other instructions
and use directly based on below table.
