Configured with an RS-232 cable connection via PC D-Sub 9-pin interface, the Datalogic M230B-00171-01040R is an in-counter, horizontal single-plane barcode scanner built for medium to high volume POS environments. 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. An auxiliary RS-232 port supports auxiliary handheld scanner attachment, scanner configuration, and label data output, and the unit can also support Sensormatic EAS systems with good-read acknowledgement through that same port. Flash memory enables field software upgrades without hardware replacement. Weighing 2.43 lb, the scanner carries RoHS environmental compliance and is backed by a 3-year limited warranty.
