Chapter 6 — Troubleshooting and Maintaining the CK30
102 CK30 Handheld Computer User’s Manual
Problems While Scanning Bar Codes (continued)
Problem Solution
You scan a valid bar code label to enter
data for your application. The data
decoded by the scan module does not
match the data encoded in the bar code
label.
The computer may have decoded the bar code label in a
symbology other than the label’s actual symbology. Try
scanning the bar code label again. Make sure you scan
the entire label.
To operate the computer quickly and efficiently, you
should enable only the bar code symbologies that you
are going to scan.
You receive a message reading “Scanner
Communication Failure” when trying to
connect a 1551E or 1553 decoded
scanner.
Make sure that:
• You are using the correct cable (P/N 3-606034-02).
• The scanner cable is attached correctly. When you
attach the scanner to the port, it should emit a single
power up beep.
• Try enabling the port state. Go to Scanners,
Symbologies > CK30 Tethered Scanner > Port
State.
• Try upgrading the scanner firmware.
• Select ASCII as the scanner model.
Your 1551E or 1553 scanner was
working fine, but after changing the port
setting you cannot change the
configuration.
The 1551E or 1553 scanner must be using the correct
RS-232 settings to allow configuration from the
Configuration Utility. Try disabling and then enabling
the scanner port state.
The configuration settings in the
Configuration Utility do not match the
settings on your 1551E or 1553.
Try disabling and then enabling the scanner port state to
synchronize the CK30 settings with the scanner.
Booting the CK30
You seldom need to warm or cold boot the CK30. The CK30
uses the configuration currently saved in flash memory during
the boot process.
You need to boot the CK30 when an application is locked up
and will not respond, when you upgrade the firmware, or when
you reflash the computer. The next instructions explain how you
warm and cold boot the CK30.
