Configuring the barcode reader in the control software
￭ Configure the barcode reader in the configuration of the control
software, as described in the online help of the software.
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.
