Step 2: Calculate the value written to the register.
Datas = (0xD4 & (! 0x03)) + 0x02 = 0xD6
Step 3: Write the value into the register.

2. Program special parameter with serial command
The serial commands used for programming the following parameters are practically irrelevant to their
programming commands.
Feature
Program the sensitivity level
Program the image stabilization timeout
Program the timeout between decodes
Program the decode session timeout
Note: Red: Address of register.
Blue: Value written to register. For example, to set the sensitivity level to 10,
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.
