Start/Stop Characters

Start/Stop characters identify the leading and trailing ends of the bar code. You
may either transmit, or not transmit Start/Stop characters.

Message Length

The message length selection is used to set the valid reading length of the bar
code. If the data length of the scanned bar code doesn’t match the valid reading
length, the scanner will not read the symbol. You may wish to set the same value
for minimum and maximum length to force the scanner to read fixed length bar
code data. This helps reduce the chances of a misread.

EXAMPLE: Decode only those bar codes with a count of 9-20 characters.

Min. length = 09

Max. length = 20

EXAMPLE: Decode only those bar codes with a count of 15 characters.

Min. length = 15

Max. length = 15

The desired message length and

Save must be input after reading this
