Honeywell Xenon 1900 Data Matrix Decoding Issues:... | terminalfaults.org

Technical Background:

Data Matrix decoding relies on precise image capture and processing. Poor decoding performance can stem from insufficient light intensity, degraded sensor sensitivity, incorrect decoder algorithms, or signal interference. Baud rate mismatches or corrupted firmware can also contribute. Environmental factors such as ESD can temporarily degrade performance.

Symptoms:

The Honeywell Xenon 1900 scanner is exhibiting difficulty decoding densely packed Data Matrix codes. This manifests as slow scan times, frequent scan failures, or an inability to decode the code altogether.

Possible Causes:

Low ambient light conditions reducing image contrast.
Contamination on the scanner window obscuring the Data Matrix code.
Incorrect configuration settings within the scanner firmware affecting decoding parameters.
Electrostatic discharge (ESD) events corrupting data transmission or internal memory.
Cable strain or damage resulting in signal attenuation and data loss.
Firmware corruption leading to decoding algorithm failures.

Solution:

1

Verify adequate ambient lighting. Supplement with external lighting if necessary.
2

Gently clean the scanner window using a lint-free cloth and isopropyl alcohol. Ensure the scanner is disconnected from power during cleaning (Safe Handling).
3

Access the scanner's configuration utility (via USB connection to a computer) and confirm that the Data Matrix decoding symbology is enabled and properly configured.
4

Check the USB or RS-232 cable for any signs of physical damage or excessive bending. Replace the cable if necessary.
5

Using the configuration utility, attempt to update the scanner's firmware to the latest version available from Honeywell.
6

If possible, test the scanner with a known-good Data Matrix code to rule out issues with the code itself.
7

If the issue persists, perform a factory reset of the scanner via the configuration utility. Note that this will erase all custom settings.

Safety Warning:

Avoid using excessive force when cleaning the scanner window. Do not use abrasive cleaners. Ensure the scanner is disconnected (Safe Handling) from the power source before cleaning. Handle the scanner cable with care to prevent damage. Do not attempt to open the scanner housing as this may damage the device and void any warranty.

Prevention:

Regularly clean the scanner window to remove dust and debris. Implement cable strain relief measures to prevent damage to the scanner cable. In dry environments prone to static discharge, consider using anti-static mats and sprays. Ensure firmware is kept up to date.

Expert Tip:

Some Data Matrix codes may be printed with very small module sizes. Increase the scanner's scan density setting (if available) in the configuration utility to improve decoding performance for these codes. Also, ensure the scanner is positioned perpendicular to the Data Matrix code for optimal reading.

Frequently Asked Questions

•What are the recommended cleaning agents for the Xenon 1900 scan window?

Isopropyl alcohol (90% or higher) and a lint-free cloth are recommended.

•Where can I find the latest firmware updates for the Xenon 1900?

Firmware updates are available on the Honeywell website under the support section for the Xenon 1900.
