2D scanner Datalogic GFS4550 Red illumination RS232 5–14V

Handheld 2D scanner Datalogic GFS4550 with red illumination is designed to decode both 2D and 1D barcodes. The imager sensor (1 MP, wide angle) and integrated red illumination enable reliable capture of printed and on-screen codes. The device connects via RS232 and operates from a 5–14 V power supply, making it suitable for retail, logistics and industrial environments that require serial connectivity and robust barcode reading.

Advantages

The scanner combines a wide-angle 1 MP imager with red illumination to improve barcode detection on varied surfaces and displays. RS232 interface ensures compatibility with legacy and industrial systems. The unit is housed in a black enclosure with IP54 protection class for resistance against dust and splashes. A serial cable (RS232) is included with the product for immediate connection.

Suitable for

• Point-of-sale terminals and retail checkout
• Warehouse and logistics scanning
• Industrial stations requiring serial (RS232) connectivity
• Environments needing a dust- and splash-resistant handheld scanner

How to use

Connect the scanner to a compatible host using the supplied RS232 cable and provide a 5–14 V power source. Aim the scanner at the barcode so the code fills the wide-angle field of view and pull the trigger (or use the host-controlled trigger) to capture the image. The imager decodes 1D and 2D barcodes and transmits the data over the RS232 interface to the connected system. Follow your host system’s settings for baud rate and serial parameters to ensure proper communication.

Recommendations

For best results, keep the scanner lens clean and avoid direct strong light shining into the imager during reading. Use the included RS232 cable for initial setup and verify serial communication settings on the host device. In dusty or damp environments, inspect seals periodically to maintain IP54 performance.
