Honeywell Xenon 1900 Barcode Scanner: Invalid Data Error... | terminalfaults.org

Technical Background:

Barcode scanners decode optical patterns into digital data, transmitting this data to the host system via serial (RS-232 or USB) communication. This process involves a specific baud rate and protocol agreed upon between the scanner and the host. An 'Invalid Data' error indicates a mismatch in the expected barcode format, corrupted data transmission due to voltage fluctuations, or signal attenuation caused by cable issues or Electrostatic Discharge (ESD).

Symptoms:

The Honeywell Xenon 1900 barcode scanner reports an "Invalid Data" error when attempting to scan barcodes. The scanner is connected to a card terminal system.

Possible Causes:

Incorrect barcode symbology configured on the scanner for the scanned barcode.
Damaged or loose cable connection between the scanner and the card terminal leading to signal loss.
Scanner firmware incompatibility with the card terminal's data processing requirements.
Electrostatic Discharge (ESD) corrupting the data transmission, particularly in dry environments.
Scanner configuration settings do not match the required data format of the card terminal.
Barcode is damaged, poorly printed, or obscured, leading to misinterpretation by the scanner.

Solution:

1

Verify the barcode symbology settings on the Honeywell Xenon 1900. Refer to the device manual to confirm the correct symbologies are enabled.
2

Inspect the cable connecting the scanner to the card terminal for any physical damage (cuts, crimps, or excessive bending).
3

Reseat the cable at both the scanner and card terminal ends to ensure a secure connection.
4

Clean the scanner window with a clean, lint-free cloth to remove any smudges or debris that may be interfering with the scan.
5

Check the card terminal's documentation or contact the card terminal vendor to determine the expected barcode format (e.g., Code 128, QR Code).
6

If possible, test the scanner with a known good barcode of the expected format to rule out barcode defects.
7

Consult the Honeywell Xenon 1900 user manual for factory reset instructions. Perform a factory reset if possible to clear any potentially corrupted settings.

Safety Warning:

Ensure the scanner and card terminal are powered off before disconnecting or reconnecting any cables (Safe Handling). Avoid using excessive force when connecting or disconnecting cables. Do not use flammable liquids or harsh chemicals to clean the scanner.

Prevention:

Regularly inspect the scanner cable for strain and damage. Clean the scanner window with a lint-free cloth. Ground yourself before handling the scanner in dry environments to prevent ESD. Consider using a barcode verifier to ensure barcode quality.

Expert Tip:

Some Honeywell scanners can be configured using a series of configuration barcodes found in the user manual. Locate the configuration barcode for factory defaults and scan it to quickly reset the scanner to its original settings. If ESD is suspected, try moving the scanner to a location with slightly higher humidity or use an anti-static mat.

Frequently Asked Questions

•What barcode symbologies are currently enabled on the scanner?

Access the scanner's configuration menu (usually via a printed configuration sheet or software) to determine the enabled symbologies.

•Has the scanner recently been moved or had its configuration changed?

Changes in location could indicate a damaged cable or ESD event. Configuration changes could have inadvertently disabled the correct barcode symbology.

•What is the make and model of the card terminal connected to the scanner?

Knowing the card terminal model allows for targeted troubleshooting and compatibility checks.
