Chapter 1 Overview

First of all, thank you for choosing Unitech’s products. This decoder build-in scanner comes in one model and supports interfaces such as keyboard wedge, RS232 serial wedge, RS232 terminal wedge, wand emulation, and the latest USB interface. In most of the cases, simply selecting an appropriate cable with a device code will work for a specific interface.

As a keyboard interface, the scanner supports most of the popular PCs and IBM terminals. The installation of the wedge scanner is a fairly simple process without any changes of software or hardware.

As a RS232 serial interface, the scanner sends data by using RS232 communication protocol. The communication speed (baud rate) ranges from 300 bps to 38400 bps with both hardware and software handshaking are implemented.
