Control command codes

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: Control command code for number 5 (ASCII
@02305CR
code )
@ 0
0x40 0x30 0x32
When transmitting commands consecutively, put more
than 100ms blank between commands.

Status Request and Status Information codes

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 delim-
iter.
Example: Status Information code "Door open"
(ASCII code @0DS01CR)
@ 0 D
0x40 0x30 0x44
