The unit is 
transmitting 
each character 
twice. 

The configuration is 
not set correctly. 

Increase interscan code delay 
setting. Adjust whether the F0 
break is transmitted.  It may be 
necessary to try this in both 
settings. 

 

Alpha 
characters show 
as lower case. 

The computer is in 
Caps Lock mode. 

Enable Caps Lock detect setting 
of the scanner to detect if the PC 
is operating in Caps Lock. 

 

Everything 
works except for 
a couple of 
characters. 

These characters 
may not be supported 
by that country’s key 
look up table. 

Try operating the scanner in Alt 
mode. 

 

The following item is only relevant for an RS232 interface. 

The com port at the 
host is not working or 
not configured 
properly. 

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. 

The unit powers 
up OK and scans 
OK but does not 
communicate 
properly with the 
host. 

The cable is not 
connected to the 
correct com port. 

Check to make sure that the cable 
is connected to the correct com 
port. 

 

Characters are 
being dropped. 

Inter-character delay 
needs to be added to 
the transmitted output.

Add some inter-character delay to 
the transmitted output by using 
the Configuration Guides  
(
