There are 15 selections for this parameter option (2 through 16
characters). Scan the proper Hex tag (Hex 2 through Hex F) to enter
your selection. The default is 4 characters.
Full ASCII
Code 39 permits full ASCII capability by encoding the additional
characters. Disable this function by scanning the Hex 0 tag, and scan
the Hex 1 tag to enable this function. Disable is the default.
Check Digit Present
The Check Digit Present parameter permits you to determine if the bar
code must contain a correct check digit to be identified as valid. If this
function is enabled, the bar code is ignored if a check digit is not
present. Scan the Hex 0 tag to disable this option, or the Hex 1 tag to
enable it. Disable is the default.
Transmit Check Digit
The Transmit Check Digit parameter selects whether to send the check
digit to the host terminal. Scan the Hex 0 tag to disable this option, or
the Hex 1 tag to enable it. The default is to disable sending the check
digit.
Allow 1- or 2-Character Tags
The Allow One- or Two-Character Tags parameter selects whether or
not to permit the scanner to read a one- or two-character Code 39 label.
If your application does not require that the scanner read a one- or
two-character Code 39 label, scan the Hex 0 tag to disable this option.
If your application requires this capability, scan the Hex 1 tag to enable
it. The default is to disable reading a one- or two-character Code 39
label.
