5.6.6 Connecting a barcode reader
The barcode reader is used as an aid for text and numerical input. You can
connect a barcode reader with USB interface.
Connect the barcode reader as follows:
1
Connect the USB plug of the barcode reader with the USB connector
of the Ti‑Touch (Type A).
2
Enter and configure the barcode reader in the device manager.
Settings on the barcode reader:
Program the barcode reader as follows (also see manual for the barcode
reader):
1
Switch the barcode reader to programming mode.
2
Specify the desired layout for the keyboard (USA, Germany, France,
Spain, German-speaking Switzerland).
This setting must match the setting in the device manager.
3
Make sure that the barcode reader is set in such a way that Ctrl char-
acters (ASCII 00 to 31) can be sent.
4
Program the barcode reader in such a way that the ASCII character
02 (STX or Ctrl B) is sent as the first character. This first character is
normally referred to as the "Preamble" or "Prefix Code".
5
Program the barcode reader in such a way that the ASCII character
04 (EOT or Ctrl D) is sent as the last character. This last character is
normally referred to as the "Postamble", "Record Suffix" or "Postfix
Code".
6
Exit the programming mode.
