RS-232 Interface

Chapter 8

Introduction

This chapter describes how to set up the digital imager scanner with an RS-232 host. The RS-232 interface is
used to connect the digital imager scanner to point-of-sale devices, host computers, or other devices with an
available RS-232 port (e.g., com port).

If the host is not listed in

Table 8-2

, refer to the documentation for the host device to set communication

parameters to match the host.

Throughout the programming bar code menus, default values are indicated with asterisks (

).

NOTE

T

he digital imager scanner uses TTL RS-232 signal levels, which interface with most system

architectures. For system architectures requiring RS-232C signal levels, Symbol offers different
cables providing TTL-to-RS-232C conversion. Contact the Symbol Support Center for more
information.
