Resolution / Answer
This setting is used to intercept, hide, insert, replace or format the scanned code data content. It is usually used when only part of the barcode content needs to be uploaded, useless characters need to be removed, or the business system requires a fixed data format.
The serial port command frame format is as follows:
STX+CMD+DA0+DA1+DA2+DA3+DA4+DA5+DA6+......+DA10+DA11+ETX+SUM
To ensure data accuracy, the last byte of a frame of data (16 bytes) is the checksum. Assume that the sum of the first 15 bytes is a, then SUM=256-(a&0xFF).
Among them:
STX=0x02; ETX=0x03 (STX and ETX values are ASCII hexadecimal definition values.)
CMD means control command or setting command
