Introduction; Connecting An Rs-232 Interface; Rs-232 Default Parameters - Motorola SYMBOL LS9203 Reference Manual

Introduction

This chapter covers RS-232 host information for setting up the scanner. The RS-232 interface is used to attach the scanner to point-
of-sale devices, host computers, or other devices with an available RS-232 port (e.g., com port).
This scanner utilizes TTL RS-232 signal levels, which will interface with most system architectures. For
system architectures requiring RS-232C signal levels, Motorola offers different cables providing the TTL to
Note
RS-232C conversion. Please contact the Global Customer Interaction Center for more information.
If the particular host is not listed in
communication parameters for hosts not listed, refer to the documentation for the host device.
Throughout the programming bar code menus, default values are indicated with asterisks (

Connecting an RS-232 Interface

This connection is made directly from the scanner to the host computer.
1. Connect the RS-232 interface cable to the rear of the scanner, as described in
2. Connect the other end of the interface cable to the serial port on the host.
3. Connect the power supply.
4. Scan appropriate bar codes in this chapter to match the host settings.
