3.4 Command trigger mode
In command trigger mode, the reading module will start shooting and reading when it
receives the trigger signal command sent by the host (that is, the bit 0 of the flag bit 0 x
0002 is written "1"); within the limited time range of "single reading time" If the reading is
successful, the reading module will output the reading content through the communication
interface and stop reading. If you need to start a new reading, you need to resend the
trigger command. If the reading exceeds the single reading time, the reading will be
suspended.
Command trigger mode
Note: In command trigger mode, the serial port command of the trigger signal is: 7E 00 08
01 00 02 01 AB CD; after the module receives the read command, the serial port returns the
write success command: 02 00 00 01 00 33 31, read mode Turn on.

3.5 Continuous Mode
Continuous mode is a working mode in which the reading module continuously and
cyclically shoots, reads and outputs information.
In this mode, the default reading interval will be 1000ms after successful reading.
In continuous mode, you can use the trigger level control to pause continuous reading or
continue continuous reading. During continuous reading, you need to maintain the trigger
