Handheld bar code reader Datalogic Gryphon I GD4590

The Datalogic Gryphon I GD4590 is a handheld 1D/2D barcode reader designed for value-added applications. It combines an ergonomic design with a high-resolution sensor and white-illumination 2D imaging to deliver reliable scanning of common linear, 2D, postal, stacked and composite codes. The device is available in High Density (HD) versions for smaller, condensed codes and in a dedicated variant for reading Digital Watermarking. The enclosure is disinfectant-ready to withstand regular cleaning, and wired interface options include keyboard wedge, RS-232 and USB connectivity.

Advantages

The Gryphon I GD4590 offers fast omnidirectional reading performance, strong motion tolerance and high first-pass decode rates even for codes displayed on mobile device screens. Disinfectant-ready housing supports frequent cleaning in healthcare and other hygiene-sensitive environments. The product is available in multiple optical configurations (including HD and Digital Watermarking-capable versions) to suit varied scanning needs.

Suitable for

• Retail point-of-sale and inventory management
• Healthcare environments requiring regular disinfection
• Ticketing and mobile-marketing applications (reading codes from phones)
• Environments needing reliable wired connectivity (USB, RS-232, keyboard wedge)

How to use

Connect the Gryphon I GD4590 to your host system using the required wired interface (USB, RS-232 or keyboard wedge). Position the scanner so the aiming area covers the barcode and trigger a scan; omnidirectional imaging enables fast reads without precise aiming. For mobile-device barcodes, align the display within the field of view and allow the imager to capture the code. Follow the host system’s setup instructions to configure interface parameters and keyboard or serial settings as needed.

Recommendations

For environments that require frequent cleaning, use disinfectants recommended by Datalogic and follow the indicated cleaning procedures to preserve the disinfectant-ready enclosure. Choose an HD model when scanning very small or high-density codes and the Digital Watermarking variant where watermark decoding is required. Use the wired connectivity options to ensure consistent, low-latency data transfer in fixed workstation setups.
