5. Setup
5.1 Connecting the Scanner
- Identify Interface: Determine the interface type required by your host system (USB, RS-232, or Keyboard Wedge). The AS-8250U supports all popular interfaces.
- Connect Cable: Plug one end of the interface cable into the scanner's interface port.
- Connect to Host: Plug the other end of the interface cable into the corresponding port on your computer or POS system.
- USB: Connect to an available USB port. The scanner is typically plug-and-play, and Windows will automatically install necessary drivers.
- RS-232: Connect to a serial port. You may need to configure serial port settings on your host system.
- Keyboard Wedge (KBW): Connect between your keyboard and the computer's keyboard port.
- Power On: Once connected, the scanner should power on automatically. The indicator light may illuminate briefly.
5.2 Driver Installation (for USB)
For USB connections, the Argox AS-8250U is designed for plug-and-play functionality with Windows operating systems. Typically, no manual driver installation is required. Upon connecting the scanner to a USB port, your operating system should automatically detect and install the necessary drivers. If prompted, follow the on-screen instructions. A Windows utility is included for advanced configuration if needed.
6. Operating the Scanner
6.1 Basic Scanning Procedure
- Prepare for Scan: Ensure the scanner is connected and powered on. Open an application on your host system where you want the barcode data to appear (e.g., a text editor, spreadsheet, or POS software).
- Aim the Scanner: Point the scanning window of the AS-8250U at the barcode you wish to read. The optimal scanning distance ranges from contact up to 250mm, depending on the barcode density.
- Press Trigger: Press and hold the trigger button. A red laser line will emit from the scanning window.
- Scan the Barcode: Position the laser line across the entire barcode. Once a successful read occurs, the scanner will typically emit an audible beep and/or the indicator light will flash. The barcode data will then be transmitted to your host system.
- Release Trigger: Release the trigger button after a successful scan.
6.2 Supported Barcode Symbologies
The AS-8250U is capable of reading a wide range of barcode types, including:
- PDF codes
- Code 16K
- All standard linear (1D) symbologies (e.g., UPC/EAN/JAN, Code 39, Code 128, Interleaved 2 of 5, Codabar, etc.)
7. Maintenance
7.1 Cleaning the Scanner
- Scanning Window: Use a soft, lint-free cloth dampened with a mild, non-abrasive cleaner (e.g., glass cleaner) to gently wipe the scanning window. Avoid harsh chemicals or abrasive materials that could scratch the surface.
- Exterior Casing: Wipe the exterior of the scanner with a soft, damp cloth. Do not allow liquids to enter the scanner's internal components.
- Cables: Inspect cables regularly for any signs of damage.
7.2 Storage
