3

Configure the keyboard in the device manager of the Touch Control
(see Touch Control manual).

3.4.6 

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.

Operation with Touch Control

Connect the barcode reader as follows:

 

1

Insert the USB plug of the barcode reader into one of the USB sock-
ets of the 867 pH Module.

 

2

Switch on the Touch Control.

The barcode reader is recognized automatically and entered in the
device manager.

 

3

Configure the barcode reader in the device manager of the Touch
Control (see Touch Control manual).

Settings on the barcode reader:

Program the barcode reader as follows (see also the manual for the bar-
code 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 (see the
Touch Control manual).

 

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
