Overview

The WD-1 is a bar code decoder for use with an IBM PC/XT/AT compatible computer or Apple Macintosh computer to decode most of the popular bar code symbologies . The WD-1 can accept and decode scanned input from a hand-held wand (light pen), a bar code slot reader, and most handheld laser or CCD non-contact scanners. It will also support an optional magnetic card reader. The magnetic card reader must be ordered separately and the buyer must specify whether the reader is to be mounted on the top of the WD1 or separate but connected with a six inch cable. Data decoded by the WD-1 is merged in with the keyboard entered data and is passed into the computer in a manner which is transparent to the operating software. A model is also available for the IBM PS2. The buyer must specify at the time of purchase whether the IBM cable or the Macintosh cable is desired.

The two connectors on the rear panel of the WD-1 allow it to be interconnected or "wedged" between the keyboard and the host personal computer and draw its power from the power supply in the personal computer, hence no external power supply or power connection is required.

The operating environment for the WD-1 is user programmed via a bar coded menu. Once established, the parameters are permanently stored in non-volatile memory for subsequent application at power-on reset.

Features
