Diagnose and resolve Honeywell Xenon 1900 barcode scanner issues after firmware update. Includes rollback procedures, cable checks, and ESD prevention.
Check the scanner's settings through the configuration utility.
Verify if the scanner is configured to read the symbologies being scanned.
Connecting directly may resolve power or data issues related to the hub.
Barcode scanners transmit data via serial protocols (e.g., RS-232, USB). Firmware updates can alter the scanner's configuration settings, impacting data encoding, baud rate, parity, or stop bits. Incorrect voltage levels (typically 5V or 3.3V) from the host device can also cause data corruption. Electrostatic discharge (ESD), especially in dry environments, can temporarily disrupt the scanner's internal electronics, leading to misreads or data errors. Signal attenuation due to cable damage or excessive cable length can also contribute to incorrect data transmission.
The Honeywell Xenon 1900 barcode scanner is reporting incorrect data following a firmware update.
Safe Handling: Avoid touching the connector pins on the scanner or host device to prevent electrostatic discharge. Unplug the scanner from the host device before performing any maintenance or inspection. Ensure the work area is dry and free from any liquids. Do not use excessive force when connecting or disconnecting the scanner cable.
Regularly clean the scanner window with a soft, dry cloth to remove dust and debris.,Ensure the scanner cable is properly connected and free from strain.,Use a surge protector to protect the scanner and host device from voltage fluctuations.,Implement ESD prevention measures, such as grounding straps and anti-static mats, especially in dry environments.,Keep the scanner away from sources of electromagnetic interference (EMI), such as power supplies and motors.
Many Honeywell scanners support configuration via a series of barcodes in the user manual. If the software utility is unavailable, try scanning the 'Factory Defaults' barcode followed by the required symbology enable/disable barcodes to quickly reconfigure the scanner.
