About The Configuration Parameters; Choosing The Symbologies The Reader Will Decode - Intermec Janus 2020 User Manual

This chapter discusses the reader's configuration parameters and files, explains how
to configure the reader, describes how to restore the default configuration, and
concludes by listing the configuration parameters.

About the Configuration Parameters

You can customize many operating characteristics of the JANUS reader, such
as the volume of its beeper and the bar code symbologies it decodes. These
characteristics are governed by configuration parameters. The values you set
for the parameters determine how the reader operates.
By customizing the reader's configuration, you can set up the JANUS 2020 to
operate easily and efficiently within your data collection system.
Note: To learn the purpose and syntax of each configuration command, see Chapter 12,
"Configuration Command Reference." The commands are listed alphabetically.
The configuration parameters can be organized into three groups, which are
discussed in the next sections: bar code symbologies, communications, and
general operation. Therefore, when you configure the reader, you are
performing one or more of these tasks:

• Choosing the Symbologies the Reader Will Decode

• Specifying How the Reader Will Communicate
• Controlling How the Reader Will Operate
Choosing the Symbologies the Reader Will Decode
This list contains all the bar code symbologies the reader can decode:
Codabar
Code 11
Code 128
Code 16K
To ensure that the reader can operate quickly and efficiently, you should
enable only the bar code symbologies that you are going to scan. If you enable
multiple symbologies, the reader may on rare occasions decode a bar code
according to the wrong symbology and produce erroneous results.
When you enable each bar code symbology, you may need to set a check digit,
the length of the bar code label, or other options. For help, see Chapter 12,
"Configuration Command Reference."
