Bar Codes - 2
Contains parameters for Code 39 bar codes.
Enable (default) Code 39 bar code reading by scanning the
Hex 1
tag and disable it by scanning the
Hex 0
tag.
If enabled, you can program the following parameters.
Defines how many characters in a bar code must be read the
same by two separate scans before determining a valid read
has occurred. Set this option to the number of characters in a
typical tag to ensure that typical tags are read with at least
two complete good scans before sending the tag data to the
host terminal or PC.
There are fourteen selections for this parameter (characters 2
through 15). Scan the proper Hex tag (
Hex 2
through
Hex F
)
to enter your selection. The default is four characters.
Code 39 permits full ASCII capability by encoding the
additional characters. Disable (default) this function by
scanning the
Hex 0
tag or scan the
Hex 1
tag to enable it.
Determines whether the bar code must contain a correct check
digit to be identified as valid. If enabled, the bar code is
ignored if a check digit is not present. If disabled (default), a
check digit within a bar code is considered part of the data
and is transmitted to the host. Scan the
Hex 0
tag to disable
this option or the
Hex 1
tag to enable it.
Determines whether the check digit is sent to the host
terminal or PC. Scan the
Hex 0
tag to disable (default) this
option or the
Hex 1
tag to enable it.
