Warranty Information
Refer to www.honeywellaidc.com/warranty for your product's warranty information.
- Unpacking: Check for damage during shipment. Verify items against your order. Save shipping container.
- Connecting USB: Connect the interface cable to the device, then to the computer. The scanner beeps upon successful connection.
- Connecting RS232 Serial Port: Turn off power, connect the appropriate interface cable to the device and then to the computer's serial port. Power up the computer after connection. The interface programs 115,200 baud, 8 data bits, no parity, and 1 stop bit by default.
- Reading Techniques: Use the view finder to center the aiming beam on the barcode. Adjust distance based on barcode size. Tilt the scanner for highly reflective codes.
- Factory Defaults: Scan the "Recall Default" barcode to reset all settings to factory defaults.
- Firmware/Serial Number: Scan specific barcodes to retrieve the firmware revision number or product serial number.
- Programming Interface: Scan the "RS232 Interface" or "USB HID Interface" barcodes to switch communication modes. The cable may need to be changed accordingly.
- Data Editing: Configure CR/LF suffix settings to append specific characters or key presses after a scanned barcode.
- Symbologies: Enable or disable various 1D, Postal, and 2D barcode symbologies using their respective configuration barcodes.
- Product Specifications: Details on mechanical, electrical, environmental, image, scan performance, and depth of field parameters.
- Maintenance: Clean the scanner window and housing with a soft cloth. Inspect cords and connectors for damage. Interface cables are field replaceable.
- Troubleshooting: Basic checks for power, aimer illumination, symbol readability, bar code display, and incorrect reading. Refer to specific sections for detailed solutions.
Troubleshooting and error codes
| Issue | Possible Cause | Solution |
|---|---|---|
| Scanner not reading symbols well | Scanner window is dirty. | Clean the window with a soft cloth or lens tissue dampened with water. |
| Symbols are smeared, rough, scratched, or have voids. | Ensure the barcode itself is clean and undamaged. | |
| Symbols are coated with frost or water droplets. | Clean the surface of the barcode. | |
| Symbols are not enabled in the scanner or decoder. | Verify that the symbology is enabled (see Chapter 4). | |
| Bar code displayed but not entered | A suffix is needed to enter the data into the application. | Program a suffix (refer to CR/LF Suffix Settings, page 3-1). |
| Scanner reads bar code incorrectly | Scanner not programmed for the appropriate terminal interface. | Reprogram the scanner with the correct Plug and Play barcode (see Programming the Interface, page 2-1). |
| Scanner not programmed to output data properly. | Reprogram the scanner with proper symbology selections (see Chapter 4). | |
| Scanner won't read bar code at all | Barcode is not readable. | Scan sample barcodes to verify scanner functionality. Check your barcode's readability. |
| Bar code symbology is disabled. | Verify that your bar code symbology is enabled (see Chapter 4). | |
| Programming options are set incorrectly or factory defaults are not restored. | Scan "All Symbologies" (page 4-1) or restore factory default settings (page 1-4). | |
| Is the power on? Is the aimer on? | The cable is not connected properly. | Check that the cable is connected properly. |
| Host system power is off (if external power isn't used). | Ensure the host system power is on. |
