Configured with a serial host interface and cable connectivity, the Datalogic M231B-00502-00000R is an in-counter horizontal barcode scanner weighing 2.43 lb. 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 -- making it well suited to medium to high-volume POS environments. Flash memory supports software upgrades in the field, and an auxiliary RS-232 port accommodates handheld scanner integration, programming, or label data output. The unit ships without cable, with USB and keyboard wedge configuration supported separately. RoHS environmental compliance is confirmed, and the scanner carries a 3-year limited warranty.
