EXAMPLE: Getting a Scan Engine Serial Number
Cmd Name = GET CAMERA PAR
Cmd_Code = 0x40
Parameter ID Code = 0x0001
Parameter Length = 16 bytes
SEND COMMAND to the ENGINE:
<write> 0x40 0x01 0x00 0xBF
The last byte 0xBF represents the checksum
GET RESPONSE from the ENGINE:
<read> 0x40 0x80 0x01 0x00 0x.. 0x.. 0x.. 0x.. 0x.. 0x.. 0x.. 0x.. 0x.. 0x.. 0x.. 0x.. 0x..
0x.. 0x.. 0x..
Tthe second byte 0x80 represents the status code that in this case
is ACK
The sixteen bytes 0x.. represent the serial number of the engine
