Honeywell Xenon 1900 Memory Error Diagnostic Report -... | terminalfaults.org

Technical Background:

The Xenon 1900 utilizes internal flash memory for firmware, configuration settings, and scanned data buffering. Memory errors can arise from corrupted firmware, data corruption due to ESD (electrostatic discharge), or voltage fluctuations affecting the memory controller's stability. Baud rate mismatches (if applicable to data transfer) are unlikely given the localized error.

Symptoms:

The Honeywell Xenon 1900 scanner displays a 'Memory Error' message, indicating a potential issue with the device's internal storage.

Possible Causes:

Firmware corruption due to interrupted update or power surge.
ESD event causing data corruption in the flash memory.
Voltage instability from the host device's USB port or power adapter (if used).
Manufacturing defect in the flash memory module.
Excessive read/write cycles exceeding the flash memory's endurance limit.
Software bug causing memory allocation issues.

Solution:

1

Safe Handling: Disconnect the scanner from the host device (computer or terminal).
2

Inspect the USB cable for damage (fraying, kinks, exposed wires). Replace if necessary.
3

Connect the scanner to a different USB port on the host device to rule out port-specific issues.
4

If using a powered USB hub, connect the scanner directly to the host device.
5

Attempt a firmware re-flash using the Honeywell EZConfig software (available from the Honeywell website). Ensure the correct firmware version for the Xenon 1900 is used.
6

If the firmware re-flash fails or the error persists, attempt a factory reset via EZConfig. Note: This will erase all custom configurations.
7

Contact Honeywell support for further assistance if the error remains after attempting the above steps. Do NOT attempt to open the scanner.

Safety Warning:

ESD (Electrostatic Discharge) can damage the scanner's internal components. Avoid touching the scanner's metal contacts or internal components. Always discharge static electricity before handling the scanner. Do NOT attempt to open the device as this will trigger anti-tamper mechanisms.

Prevention:

Regularly clean the scanner window with a clean, dry, lint-free cloth to maintain optimal scanning performance. Avoid using harsh chemicals or abrasive cleaners.,Ensure the USB cable is properly connected and not subjected to excessive strain or bending.,Implement ESD control measures, especially during dry winter months (e.g., using anti-static mats, wrist straps).,Use a surge protector to protect the scanner and host device from power surges.,Avoid exposing the scanner to extreme temperatures or humidity.

Expert Tip:

If the scanner is frequently used in a high-static environment, consider using a USB isolator to protect the host device from ESD damage. Also, verify the power supply is providing stable voltage (5V +/- 5%).
