Possible Causes
The configuration is
not set correctly.
The computer is in
Caps Lock mode.
These characters
may not be supported
by that country's key
look up table.
The com port at the
host is not working or
not configured
properly.
The cable is not
connected to the
correct com port.
Inter-character delay
needs to be added to
the transmitted output.
Solution
Increase interscan code delay
setting. Adjust whether the F0
break is transmitted. It may be
necessary to try this in both
settings.
Enable Caps Lock detect setting
of the scanner to detect if the PC
is operating in Caps Lock.
Try operating the scanner in Alt
mode.
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 to make sure that the cable
is connected to the correct com
port.
Modify the scanner's configuration
to add some inter-character delay
to the transmitted output.
