Settings of the barcode reader
The barcode reader requires certain basic settings. You will find directions
in the Instructions for Use as to how you can program the barcode reader.
Switch the barcode reader to programming mode and make the following
settings:
1 ￭ Select the keyboard layout for the desired country (USA, Ger-
many, France, Spain, Switzerland (German)). This setting must
match the setting in the control software.
￭ Make sure that the Ctrl characters (ASCII 00 to 31) are allowed to
be sent.
￭ Adjust the settings so that the ASCII character 02 (STX or Ctrl B) is
sent as the first character as "Preamble" or "Prefix Code".
￭ Adjust the settings so that the ASCII character 04 (EOT or Ctrl D) is
sent as the last character as "Postamble" or "Record Suffix" or
"Postfix Code".
￭ Exit programming mode.
