parameter configuration is completely matched .
The default serial communication parameters of the reading module are as follows :
parameter Default parameter value
baud rate 9600bps
Check Digit no verification
data bits 8 bits
stop bit 1 person
hardware flow
control
No flow control
1.1 Read flag bit operation
For the read operation of device flag bits, up to 256 bytes of flag bits can be read at one time .
Command format :
Input : {Head1} {Types} {Lens} {Address} {Datas} {CRC}
Among them :
Head1 : 0x7E 0x00 (2 bytes)
Types : 0x07 (1 byte)
Lens : 0x01 (1 byte)
