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)
@ 1 2 0 P R O N CR
0x40 0x31 0x32 0x30 0x50 0x57 0X4f 0x4e 0x0d
