1. Setup
1.1 Unboxing and Initial Inspection
Carefully remove all components from the packaging. Verify that the following items are present:
- Opticon OPN-3102i Companion Scanner
- USB Cable
- Strap (if included in your package)
Inspect the scanner for any visible damage. If any components are missing or damaged, contact your vendor immediately.
1.2 Charging the Scanner
Before first use, fully charge the scanner. The OPN-3102i supports charging via USB and Qi wireless charging.
- USB Charging: Connect the supplied USB cable to the scanner's USB port and to a powered USB port on a computer or a USB wall adapter.
- Qi Wireless Charging: Place the scanner on a compatible Qi wireless charging pad. Ensure the scanner is correctly positioned for charging to begin.
The charging indicator light on the scanner will provide feedback on the charging status.
1.3 Connecting to a Host Device
The OPN-3102i can connect to host devices (Smartphones, Tablets, Windows PCs) via Bluetooth or USB.
1.3.1 Bluetooth Connection (HID/SPP)
The scanner supports Bluetooth Human Interface Device (HID) and Serial Port Profile (SPP) modes.
- Power On: Press and hold the scan button until the scanner powers on.
- Enter Pairing Mode: Refer to the scanner's quick start guide or the manufacturer's website for specific instructions on entering Bluetooth pairing mode (often involves scanning a special barcode or holding a button).
- Pair with Device: On your host device (iOS, Android, Windows), navigate to Bluetooth settings, search for available devices, and select "OPN-3102i" from the list.
- Confirm Connection: The scanner's indicator light will change to confirm a successful connection.
For HID mode, the scanner acts as a keyboard, inputting scanned data directly into any active text field. For SPP mode, a dedicated application is usually required to receive data.
1.3.2 USB Connection
For direct connection to a computer, use the supplied USB cable.
- Connect one end of the USB cable to the OPN-3102i scanner.
- Connect the other end to an available USB port on your computer.
- The computer should recognize the scanner as a Human Interface Device (HID) or a serial device, depending on the scanner's configuration. Drivers may be required for certain operating systems or SPP mode.
2. Operating the Scanner
2.1 Basic Scanning
To scan a barcode:
- Ensure the scanner is powered on and connected to your host device.
- Point the scanner's window at the barcode you wish to scan.
- Press the scan button. A red aiming laser will appear, followed by a green confirmation light and an audible beep upon successful scan.
- The scanned data will be transmitted to your connected host device.
The OPN-3102i is a 2D CMOS imager, capable of reading both 1D and 2D barcodes.
2.2 NFC Functionality
The OPN-3102i includes Near Field Communication (NFC) capabilities. This can be used for quick pairing with compatible devices or for specific data transfer applications. Refer to your application's documentation for details on NFC usage.
3. Maintenance
3.1 Cleaning the Scanner
Regular cleaning helps maintain optimal performance.
- Use a soft, lint-free cloth slightly dampened with water or a mild, non-abrasive cleaning solution to wipe the exterior of the scanner.
- For the scanning window, use a lens cleaning cloth to avoid scratches.
- Do not use harsh chemicals, solvents, or abrasive materials, as these can damage the scanner's casing or optics.
- Ensure no liquid enters the scanner's ports or openings.
3.2 Storage
When not in use, store the scanner in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, ensure the battery has a partial charge (around 50%) to prolong battery life.
4. Troubleshooting
This section addresses common issues you might encounter with your OPN-3102i scanner.
4.1 Scanner Not Powering On
- Check Battery: Ensure the scanner is sufficiently charged. Connect it to a power source using the USB cable or a Qi charging pad.
- Power Button: Confirm you are pressing and holding the correct power button for the required duration.
4.2 Unable to Connect via Bluetooth
- Scanner in Pairing Mode: Verify the scanner is in Bluetooth pairing mode.
- Host Device Bluetooth: Ensure Bluetooth is enabled on your smartphone, tablet, or computer.
- Forget Device: If previously paired, try "forgetting" or "unpairing" the scanner from your host device's Bluetooth settings and then re-attempt the pairing process.
- Proximity: Ensure the scanner is within the Bluetooth range of the host device.
- Interference: Move away from other wireless devices that might cause interference.
4.3 Scanner Not Reading Barcodes
- Aiming: Ensure the aiming laser is centered on the barcode.
- Barcode Quality: Check if the barcode is damaged, smudged, or poorly printed.
- Distance: Adjust the distance between the scanner and the barcode.
- Lighting: Ensure adequate lighting, but avoid direct glare on the barcode.
- Symbology: Verify that the scanner is configured to read the specific barcode symbology (e.g., QR Code, Data Matrix, UPC-A).
4.4 Scanned Data Not Appearing on Host Device
- Connection Status: Confirm the scanner is successfully connected to the host device (Bluetooth or USB).
- Application Focus: For HID mode, ensure there is an active text field or application ready to receive input on your host device.
- SPP Mode: If using SPP mode, verify your application is correctly configured to receive data from the scanner's serial port.
