Honeywell Xenon 1900: Garbled Data Diagnostic - Solar Faults | terminalfaults.org

Technical Background:

Data corruption during transmission can arise from several hardware and software related issues. These include incorrect baud rate settings, voltage fluctuations, electromagnetic interference (EMI), electrostatic discharge (ESD), and cable signal attenuation. The scanner relies on serial or USB communication protocols; mismatched parameters can cause data misinterpretation.

Symptoms:

Xenon 1900 barcode scanner reads barcodes but transmits corrupted or unreadable data to the host system. Data transmission errors are observed instead of accurate barcode values.

Possible Causes:

Incorrect baud rate or data format settings on the scanner or host system.
Electrostatic discharge (ESD) events damaging the scanner's communication circuitry.
Cable damage causing signal attenuation or data corruption during transmission.
Electromagnetic interference (EMI) from nearby electronic devices.
Loose or improperly connected cable connections.
Faulty USB or serial port on the host system.

Solution:

1

Safe Handling: Disconnect the Honeywell Xenon 1900 scanner from the host system to prevent further data errors during diagnosis.
2

Verify Baud Rate: Check the scanner's configuration settings and confirm they match the host system's expected baud rate, parity, data bits, and stop bits.
3

Reseat Cables: Ensure the scanner cable is securely connected to both the scanner and the host system. Try a different USB port on the host.
4

Test Cable Integrity: If possible, replace the scanner cable with a known good cable to rule out cable damage.
5

Scan Default Configuration: Scan the factory default configuration barcode (if available) to reset the scanner to its original settings.
6

Host System Port Test: Test the host system's USB or serial port with another device to verify its functionality.
7

ESD

Safety Warning:

Electrostatic discharge (ESD) can damage the scanner's internal components. Handle the scanner with care, especially in dry environments. Do not expose the scanner to excessive moisture or extreme temperatures. Ensure proper grounding to prevent electrical hazards. Safe Handling: Always disconnect the scanner before performing any cleaning or maintenance.

Prevention:

Ensure the scanner and the surrounding area are free from static electricity. Use anti-static mats and grounding techniques.

Prevention:
Regularly clean the scanner window with a lint-free cloth to ensure accurate barcode reading. Implement cable strain relief measures to prevent cable damage. Periodically check and tighten cable connections. Maintain a controlled humidity environment to minimize ESD events.

Expert Tip:

Many Xenon 1900 scanners have a 'test menu' accessible via a specific barcode sequence. Scanning this barcode enables verbose error reporting and detailed diagnostic information that may pinpoint the exact source of the 'garbage data' issue. Consult the Honeywell Xenon 1900 product manual for the 'test menu' barcode.
