WSDU User Manual February 8, 2019 1. Introduction The Wearable Scan and Display Unit (WSDU) is a purpose-built, extremely lightweight (less than 150gm) wearable barcode scanner. It is used with the Manual Sortation Appliance (MSA) and communicates with the MSA server via a 915MHz ISM band “wireless cable” communications channel.
