Honeywell Xenon 1900: Barcode Scanner Reads Backwards -... | terminalfaults.org

Technical Background:

Barcode scanners use an emitter and sensor to detect variations in reflected light from the barcode. The scanner decodes the pattern based on pre-programmed configurations and transmits the data via a communication interface (USB, RS232). A configuration error can reverse the decoding logic.

Symptoms:

Honeywell Xenon 1900 scanner consistently reads barcodes in reverse order.

Possible Causes:

1. Incorrect configuration setting causing reversed barcode interpretation.
2. Corrupted firmware within the scanner.
3. Incompatible interface settings (baud rate, parity) if using RS232.
4. Damaged or loose interface cable causing data transmission errors.
5. Electrostatic discharge (ESD) altering the scanner's configuration.
6. Software conflict on the host system interfering with data interpretation.

Solution:

1

Scan the appropriate configuration barcode from the Honeywell Xenon 1900 User Guide to reset to factory defaults. This often resolves configuration errors.
2

Verify the scanner is properly connected to the host system and the cable is securely attached at both ends.
3

If using RS232, confirm the baud rate, parity, and data bits settings match the host system's requirements.
4

Update the scanner's firmware to the latest version using the Honeywell software utility. Download from the Honeywell website.
5

Test the scanner with a different host system or computer to isolate the problem. This helps determine if the issue is with the scanner or the original host system's software.
6

Check for software conflicts on the host system by temporarily disabling other applications that may be interfering with the scanner's data input.
7

If the scanner connects via USB, test with a different USB port or USB cable.

Safety Warning:

Safe Handling: Unplug the Honeywell Xenon 1900 scanner from the power source and host system before performing any cleaning or inspection. Avoid using excessive force when connecting or disconnecting cables. Static electricity can damage electronic components; ground yourself before handling the scanner.

Prevention:

Regularly clean the scanner's window with a soft, lint-free cloth to prevent dust accumulation. Use isopropyl alcohol if necessary.,Ensure the interface cable is properly secured and free from strain. Avoid sharp bends or kinks in the cable.,Store the scanner in a safe location to prevent physical damage.,Implement ESD control measures, especially during dry winter months. Use anti-static mats and wrist straps when handling the scanner.,Periodically check for and install firmware updates from the manufacturer to address potential software bugs.

Expert Tip:

Some Honeywell scanners have a 'test barcode' in the manual. Scanning this barcode confirms basic functionality. If *that* barcode is reversed, it's almost certainly a configuration error. Also, use a USB cable with a ferrite choke to minimize EMI.

Frequently Asked Questions

•What is the default configuration barcode for Honeywell Xenon 1900?

Consult the Honeywell Xenon 1900 User Guide for the specific barcode. It's usually a 'Factory Default' or 'Standard Configuration' barcode.

•How do I update the firmware on the Xenon 1900?

Download the Honeywell Scanning and Mobility software from their website. Follow the instructions in the software to update the firmware.

•What RS232 settings are commonly used?

Common settings are 9600 baud, no parity, 8 data bits, and 1 stop bit (9600-N-8-1). Verify settings on the host system.
