Intermec cn30 User Guide

If you are having problems sending or receiving data through the integrated 
serial port on the CN30 Computer, check these possible problems:

• Make sure the CN30 Computer is connected to the PC, host computer, 

or RS-232 serial device using the appropriate cable adapter and null 
modem cable.

• If the CN30 Computer is in a communications dock, make sure that the 

communications dock is connected to the serial device using the appro-
priate cable.

For more information on using the serial port, see “Configuring Serial 
Communications” on page 107.

The Network Connection icon is in the status bar, but 
the host computer is not receiving any data from the 
CN30 Computer.

In a UDP Plus network, there may be a problem with the 
connection between the Intermec Application Server and 
the host computer. Check with your network administra-
tor or see the user’s manual for the Intermec Application 
Server.

In a TCP/IP network, there may be a problem with the 
connection between the access point and the host com-
puter. Check with your network administrator or use 
your access point user’s manual.

You cannot see a red beam of light from the scanner when 
you press the Scan button and aim the scanner at a bar 
code label.

There are two possible problems:

• You may be too far away from the bar code label. Try 

moving closer to the bar code label and scan it again.

• You may be scanning the bar code label “straight on.” 

Change the scanning angle and try again.

You can test the effective range of the scanner. Move 
within 2 feet of a wall and test the scanner. You need to be 
within the scanning range to scan bar code labels. For 
help scanning bar codes, see “Scanning Bar Codes” on 
page 5.

When you release the Scan button or handle trigger, the 
Good Read light does not turn off.

The Good Read light will remain on if you configure the 
CN30 Computer to use continuous/edge triggering. If 
you configure the CN30 Computer for level triggering 
and the Good Read light remains on, there may be a 
problem. Press the Scan button or pull the trigger again 
without scanning a bar code label. If the light is still on, 
contact your local Intermec representative.

The input device attached to the CN30 Computer does 
not appear to work well or read bar code labels very 
quickly.

Try setting the Scanner Model command to the specific 
input device you have attached. Check the bar code sym-
bologies you have enabled on the CN30 Computer. 
Enable only the symbologies that you are using.
