Chapter 5 Serial Interface

Introduction

This chapter describes how to set up the decoder with a serial host. The serial

interface is used to connect the decoder to point-of sale devices, host

computers, or other devices with an available serial port (e.g. com port).

Note: The decoder uses TTL signal levels, which interface with most system

architectures. System architectures that use RS-232C signal levels require a

conversion circuitry.

The serial host type requires proper configuration of the sysconfig lines, and

typically require scanning bar code menus as part of initial configuration.

Most computer monitors allow scanning the bar codes directly on the screen.

When scanning from the screen is sure to set the document magnification to a

level where the bar code can be seen clearly, and bars and/or spaces are not

merging.
