Possible Cause(s)
Check the character length
lock.
The aspect ratio of the bar
code is out of tolerance.
The bar code may have been
printed incorrectly.
The scanner is not configured
correctly for this type of bar
code.
The minimum symbol length
setting does not work with the
bar code.
The com port at the host is not
working or is not configured
properly.
The cable is not connected to
the proper com port.
The com port is not operating
properly.
The scanner and host may not
be configured for the same
interface.
The intercharacter delay needs
to be added to the transmitted
output.
Check if it is a check digit, character or border problem.
Check if check digits are set properly.
Check if the correct minimum symbol length is set.
Check to make sure that the baud rate and parity of the scanner
and the communication port match and the program is looking for
RS232 data.
Check that the scanner and the host are configured for the same
interface.
Add some intercharacter delay to the transmitted output
by using the MetroSelect Configuration Guide
(
00-02407x).
