Barcode Reader Operations (Release number 3 or later)
When you scan communication commands with a barcode reader, the DX will respond
as follows.
• The DX will accumulate key codes until it reaches a terminator. Then it will execute
the accumulated character string. The terminator is the enter key code.
• The DX can accumulate up to 200 characters, not including the terminator. The DX
will process a character string when it reaches 200 characters in length.
• The DX can read ASCII characters (128 characters: numbers, symbols, and
uppercase and lowercase letters of the alphabet).
Note
• Barcode reader operations are treated as key operations.
• Barcode reader operations except the operation using UD command are limited by the
settings of the key lock and login functions.
