Setting the barcode reader
The barcode reader requires certain basic settings. You can find instruc-
tions on how to program the barcode reader in the manual for the bar-
code reader. Set the barcode reader into program mode and configure the
following settings:
1
￭ Specify the keyboard layout for the desired country (USA, Ger-
many, France, Spain, German-speaking Switzerland). This setting
must match the setting in the control software.
￭ Make sure that the Ctrl characters (ASCII 00 to 31) can be sent.
￭ Set the "Preamble" (introduction) or "Prefix Code" for the ASCII
character 02 (STX or Ctrl B) to be sent as the first character.
￭ Set the "Postamble", "Record Suffix" or "Postfix Code" for the
ASCII character 04 (EOT or Ctrl D) to be sent as the last character.
￭ Close programming mode.
