If you are having problems sending or receiving data through the
integrated serial port on the CK31G, check these possible
problems:
• Make sure the CK31G is connected to the PC, host
computer, or RS-232 serial device using the appropriate cable
adapter and null modem cable.
• If the CK31G is in a communications dock, make sure that
the communications dock is connected to the serial device
using the appropriate cable.
For more information on using the serial port, see "Configuring
Serial Communications" on page 33.
Solution
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 61 cm (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 20.
