Check Digit
Matrix 2 of 5 may include Check Digit (not compulsory) following its barcode
messages. It veri fi es the barcode message.
“
NO Check, Transmit All
”
means to read without check and transmit
»
all bytes including barcode message and Check digit.
“
Check, Do Not Transmit Check Digit
”
means to read and check. If
»
veri fi cation is successful, transmits barcode message; if not, engine will not
send barcode message to the Host.
“
Check, Transmit All
”
means to read and check. If veri fi cation is »
successful, transmits all messages; if not, engine will not send barcode mes-
sage to the Host.
When
“
Check, Do Not Transmit Check digit
”
is enabled and barcode message length
minus one is less than Min Message Length, it will lead to an error.
E.g.
：
Reading a 4-byte (include check Digit) Matrix 2 of 5 with the Min Message Length
being 4 bytes and
“
Check, Do Not Transmit Check digit
”
enabled leads to an error.
The number of Matrix 2 of 5 barcode bits(check digit contained) must be even. If it is odd, a 0 will be
added as the fi rst digit. The check digit generates automatically when a barcode is produced.
