Problems Transmitting Data through the Serial Port
If you are having problems sending or receiving data through the integrated
serial port on the CK60 Computer, check these possible problems:
• Make sure the CK60 Computer is connected to the PC, host computer,
or RS-232 serial device using the appropriate cable adapter and null
modem cable.
• If the CK60 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 53.
Problems While Scanning Bar Codes
Problem Solution
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 4.
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
CK60 Computer to use continuous/edge triggering. If
you configure the CK60 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.
