Master GD4590 Barcode Scanner

The Master GD4590 is a handheld imager that reads both 1D and 2D barcodes. It connects via a wired USB interface for direct power and data transfer. The device is supplied in new condition for immediate deployment.

Wired USB suits fixed stations.

This scanner suits checkout counters, inventory desks and library stations where a constant USB link is practical. Workers who need to roam aisles or scan from a distance should consider a cordless model instead.

Imager reads 1D and 2D codes

The built-in imager captures linear and matrix symbols in a single scan engine. No separate laser or camera module is required for either format. This capability determines whether the unit matches your symbology requirements.

Questions about this item

What does the wired USB interface cap the data rate at in practice?

The wired USB link limits throughput to the host controller's bulk-endpoint bandwidth, so sustained scan rates stay within that ceiling.

What physical space does the GD4590-BK handset need on a countertop or mount?

The handheld imager fits in a standard cradle footprint and requires only a few centimetres of clearance above the scan window.

How is the scanner installed, and which step do people often miss?

Plug the USB cable into the host, wait for the driver to enumerate, then scan the factory-default configuration code to enable 2D symbologies.
