Control commands:
The control command packets have a data length of 7~10 bytes. ASCII codes from 0x00 to 0x7f are used to receive serial data. At the transmission end, take steps to convert the ASCII codes into HEX data to set the data in the data packets. CR (0x0d) is added as the data packet delimiter.
Example: Reception Time command (ASCII code @12011)
@ | 1 | 2 | 0 | 1 | 1 | CR |
0x40 0x31 0x32 0x30 0x31 0x31 0x0d
When transmitting commands consecutively, put more than 100ms blank between commands.
Status data transmission:
The status data packets have a fixed data length of 8 bytes. ASCII codes from 0x00 to 0x7f are used to transmit serial data. For this reason, the ASCII codes are converted into HEX data before the data is set in the data packets and transmitted. CR (0x0d) is added as the data packet delimiter.
Example: Transmission "Power ON" (ASCII code @120PRON)
