Introduction; Connecting An Rs-232 Interface - Symbol LS 4208 Manual

Introduction

This chapter describes how to set up the scanner with an RS-232 host. The RS-232 interface is used to connect the 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
host.
The scanner uses TTL RS-232 signal levels, which interface with most system architectures. For system
architectures
TTL-to-RS-232C
Note

Connecting an RS-232 Interface

This connection is made directly from the scanner to the host computer.

The connectors may be different than those illustrated, but the steps to connect the scanner remain the
same.
