Problems While Scanning Bar Codes (continued)

Problem

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.

You receive a message reading “Scanner Communication Failure” when trying to connect a 1551E or 1553 decoded scanner.

Your 1551E or 1553 scanner was working fine, but after changing the port setting you cannot change the configuration.

The configuration settings in the Configuration Utility do not match the settings on your 1551E or 1553.

Solution

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.

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.

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.

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.
