1. Abstract
This manual provides specifications for the OPL-2724 wireless barcode scanner.
This scanner is a laser barcode scanner which is able to detect black or colored barcodes on the white or
colored back ground.
2. Overview
- OPL-2724 is a wireless barcode scanner.
- The use of a short-wavelength red laser beam enhances visibility when scanning lines.
- To scan a barcode, press the trigger switch without the optical window of this scanner touching the
objective barcode.
- Supported symbologies are: WPC (EAN, JAN, UPC-A / UPC-E), industrial 2of5, IATA, interleaved 2of5,
NW-7 (Codabar), Code-39, Code-93, Code-128, EAN-128 and MSI Plessey.
- Code options, read options and communication settings can be configured by sending commands.
- Scanned data is transferred to the designated device via wireless communication (Bluetooth V2.0).
- If the OPL-2724 is disconnected because it is out of range or the Bluetooth device is not available,
scanned data will be saved in the built-in memory of the scanner.
- OPL-2724 uses 2 size AAA alkali batteries for its power supply.
- This product is compliant with RoHS.
