Bar code length locking configuration (support up to 6 bar code type length locking).
Add a single bar code type length lock configuration process:
Example 1: The length of code 128 is 10, and the byte value of code 128 is 083 by looking up the barcode type table.
-
Scan "enter / exit programming mode" to put the device into programming mode.
-
Scan "configure barcode type 1 length".
- Scan bytecode values "0", "1", "0" in turn.
- Scan "configure barcode type 1 byte value".
- Scan byte code values "0", "8" and "3" in turn.
- Scan "enter / exit programming mode".
Add length lock for multiple barcode types:
Example 2
- Scan "enter / exit programming mode" to put the device into programming mode.
- Scan "configure barcode type 1 length".
- Scan bytecode values in turn.
- Scan "configure barcode type 1 byte value".
- Scan bytecode value in turn.
- Scan "configure barcode type 2 length".
- Scan bytecode values in turn.
- Scan "configure barcode type 2 byte value".
- Scan bytecode values in turn.
- Scan enter / exit programming mode.

Add Prefix / Suffix (up to 10 characters can be added respectively)
Add prefix process:
Example 1: add a byte prefix, the character is "", and the corresponding ASCII decimal number is 040.
- Scan "enter / exit programming mode" barcode.
- Scan "configuration the 1st prefix" barcode.
- Scan digital barcodes "0", "4", "0"
- Scan "enter / exit programming mode" barcode.
Add suffix process:
Example 2: add a suffix of byte, the character is “)”, and the corresponding ASCII decimal number is 041.
- Scan "enter / exit programming mode" to put the device into programming mode.
- Scan "configuration suffix 1st byte".
- Scan bytecode values "0", "4", "1" in turn.
- Scan "enter / exit programming mode".
Add multiple byte prefix:
Example 3, add multiple byte prefixes
- Scan "enter / exit programming mode" to put the device into programming mode.
- Scan "configuration prefix 1st byte".
- Scan the first byte code value in turn.
- Scan "configuration prefix 2nd byte".
- Scan the second byte code value in turn.
- Repeat steps 4 and 5
- Scan "enter / exit programming mode".
Add multiple byte suffix:
Similar to adding multiple prefixes.
Clear all prefixes:
Scan the clear all prefixes barcode.
Clear all suffixes:
Scan the clear all prefixes barcode.
