Figure 35: Settings for Program selection via barcode
The following settings can be altered:
• Baud rate: the baud rate at which the barcode scanner works
• Data Bits: data bits selected can be 5, 6, 7 or 8
• Stop Bits: stop bits selected can be 1 or 2
• Parity: the parity can be selected from none, even or odd
• End marker for barcode: end marker which the barcode scanner sends once a bar-
code has been read. Any character within the range 0x0A – 0x0F.
• if a barcode is selected for Program Choice in the Basic Settings then the following
settings are available:
o Range mask: this determines which part of the scan code read for program
choice is used. Only one mask can be set which is valid for all programs.
o Scan code mapping: for each program from 1 to 15 a range of codes is se-
lected for each of the programs. The start and end of these ranges is en-
tered. The ranges may not overlap. If only one code is required for the Pro-
gram Choice then the same start and end code can be entered.
IMPORTANT
The length of the barcode must be a maximum of 30 characters.
