Possible Causes
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
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.
Add some inter-character delay to
the transmitted output by using
the Configuration Guides
( 00-02544 and 00-02281).
