Suffix string setting: The <enter > key is represented in different ASCII when it is applied by different OS.
For a Windows/DOS OS, <enter> is represented as <CR><LF> (0x0D 0x0A); for an Apple MAC OS,

Insert G1/G2/G3/G4 string setting: The engine offers 4 positions and 4 character strings to insert among
the barcode data string.
Example: Set G1 string to be “AB”.
Original code data “1 2 3 4 5 6”
Output code data
“1 2 A B 3 4 5 6”
Steps:
1) Scan SETUP and Insert G1 string setting barcode.
2) Use the ASCII table to find the value of A→41, B→42.
3) Scan 4, 1 and 4, 2 in section “6-32 Configuration alphanumeric entry barcode (as Para. value)”.
4) Scan END barcode.
