Step 2: Calculate the value written to the register.
Datas = (0xD4 & (! 0x03)) + 0x02 = 0xD6
Step 3: Write the value into the register.
serial command sent : 0x7E 0x00 0x08 0x01 0x00 0x00 0xD6 0xDF 0x22
reply received : 0x02 0x00 0x00 0x01 0x00 0x33 0x31
2. Program special parameter with serial command
The serial commands used for programming the following parameters are practically irrelevant to their
programming commands.
Feature Serial Command
Program the sensitivity level 0x7E 0x00 0x08 0x01 0x00 0x03 0xTT 0xSS 0xSS
Program the image stabilization timeout
0x7E 0x00 0x08 0x01 0x00 0x04 0xTT 0xSS 0xSS
Program the timeout between decodes 0x7E 0x00 0x08 0x01 0x00 0x05 0xTT 0xSS 0xSS
Program the decode session timeout 0x7E 0x00 0x08 0x01 0x00 0x06 0xTT 0xSS 0xSS
Note: Red: Address of register.
Blue: Value written to register. For example, to set the sensitivity level to 10, 0xTT should be 0x0A .
Pink: CRC checksum calculated.
3. Save register data in EEPROM
Scanning a programming barcode can change register value and save register data in EEPROM as well.
As for command programming, it requires a write command and a save command to perform these two
tasks. To save register data in an external EEPROM, users need to send the save command to the
scanner.
save command sent: 0x7E 0x00 0x09 0x01 0x00 0x00 0x00 0xDE 0xC8
