11.2
BARCODE READER
If 'USB Auto Scan is set to 'Yes' in Display Configuration (Section 6.1.3) then, with the barcode reader plugged
into the USB port, the scanned data input stream is packaged into a general message displayed on the vertical
trend and message displays and included in the .uhh history file. The format of the message is: DD/MM/YY
HH:MM:SS 123--13 (where 123--13 represents the ASCII data read from the barcode).
Note: The message and the vertical trend displays do not auto refresh so the display is not
automatically updated when the barcode scanner is used. The message is, however, updated
in the message list.
If 'USB auto Scan' is set to 'No, the ASCII data read from the barcode is displayed as a message ready for
editing prior to being sent to the display etc. Figure 134 shows an example.
Note: The barcode reader must be configured to use a carriage return (decimal 13) terminating
character.
