RS-232 Interface

Chapter 7 RS-232 Interface

Introduction

This chapter describes how to set up the digital scanner with an RS-232 host. The RS-232 interface is used to

connect the digital 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 7-2, 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 The digital 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.

*Baud Rate 57,600 Feature/Option

* Indicates Default

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

scanning from the screen, be 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.
