The Datalogic M231B-00101-01040R is a horizontal, single-plane in-counter barcode scanner with EAS capability, configured for serial host interface connectivity and supplied as a kit with an RS-232 cable — the USB cable is ordered separately. Weighing 2.43 lb, it reads 1D barcodes and autodiscriminates all standard 1D codes including GS1 DataBar Linear codes, as well as GS1 DataBar Stacked, GS1 DataBar Stacked Omnidirectional, and GS1 DataBar Expanded Stacked. Flash memory supports field software upgrades, and an auxiliary RS-232 port accommodates a handheld scanner, configuration access, or label data output, while Checkpoint EAS integration and Sensormatic EAS acknowledgement via that same port cover electronic article surveillance requirements. RoHS compliant, this unit carries a 3-year limited warranty and is suited to medium- to high-volume POS environments including drug stores, convenience stores, and grocery retail.
