CCD reader VIRTUOS HT-310A long range USB with RS-232 keyboard emulation

The VIRTUOS HT-310A long range CCD reader is a handheld barcode scanner designed for extended-distance reading up to 0.5 m. Supplied with a stand and a 1.8 m cable, the scanner reads 1D barcodes from various surfaces, including transparent packaging and displays. The device features increased sensitivity for very small codes, robust ABS-and-rubber housing tested to withstand drops from up to 1.5 m, and a USB interface that can emulate both a keyboard and a serial (RS-232) port for easy integration with POS systems, terminals and PCs.

Advantages

The HT-310A offers long read range (20–500 mm) and a wide reading field up to 250 mm, with a high capture rate of 270 scans/s and resolution down to 3 mil (0.075 mm). It supports automatic code detection or manual trigger operation, reads through challenging surfaces such as transparent packaging, and decodes a broad set of 1D symbologies. The unit is compact and lightweight (166 × 66 × 86 mm, 120 g without cable) and meets FCC Class B and CE standards.

Suitable for

• Retail checkout and point-of-sale terminals
• Warehousing and inventory control
• Logistics and shipping areas
• Workplaces requiring reading of small or low-contrast barcodes (e.g., jewellery)

How to use

Connect the VIRTUOS HT-310A to a computer or POS terminal via the supplied USB cable; the device will operate in keyboard-emulation or serial-emulation mode depending on host configuration. Place the scanner in the included stand for hands-free operation or hold it manually and align the scanner so the barcode falls within the read field. Use the trigger button for manual reads or rely on automatic detection for continuous scanning. Ensure the targeted barcode is within the specified 20–500 mm range and oriented within the maximum 45° angle for reliable decoding.

Usage recommendations

For best results, clean scanner window regularly and avoid direct, intense lighting sources aimed at the scan area. Use keyboard-emulation mode for simple plug-and-play integration with POS software, or select serial emulation for systems requiring RS-232 communication. Store and operate the device within the specified temperature and humidity ranges.
