Chapter 6 — Troubleshooting and Maintaining the CK30
100 CK30 Handheld Computer User’s Manual
Problems With Wireless Connectivity (continued)
Problem Solution
The network connection icon is in the
status bar, but the host computer is not
receiving any data from the CK30.
In a UDP Plus network, there may be a problem with
the connection between the DCS 30X or Intermec
Gateway and the host computer. Check with your
network administrator or see the user’s manual for the
DCS 30X or Intermec Gateway.
In a TCP/IP network, there may be a problem with the
connection between the access point and the host
computer. Check with your network administrator or
use your access point user’s manual.
Problems Transmitting Data Through the Serial Port
If you are having problems sending or receiving data through the
integrated serial port on the CK30, check these possible
problems:
• Make sure the CK30 is connected to the PC, host computer,
or RS-232 serial device using the appropriate cable adapter
and null modem cable.
• If the CK30 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 39.
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 20.
