The Datalogic M231B-20500-00000R is a cabled, in-counter horizontal single-plane scanner configured with DLS colors and logo, standard EAS interlock, LLT top, and USB/KBW configuration — shipped without power supply, mount, or cable. It autodiscriminates all standard 1D codes including GS1 DataBar Linear codes, and extends that capability to stacked symbologies: GS1 DataBar Stacked, GS1 DataBar Stacked Omnidirectional, and GS1 DataBar Expanded Stacked. The serial host interface connects to POS systems at the checkout lane, while an auxiliary RS-232 port supports Checkpoint EAS integration and Sensormatic EAS acknowledgement. Flash memory enables field software upgrades without hardware replacement. Weighing 2.43 lb, the unit carries RoHS environmental compliance and is backed by a 3-year limited warranty, positioning it for medium-to-high-volume retail checkout environments including drug, convenience, and specialty stores.
