Sending Commands From a Host Computer
You can create reader applications that use Reader Services to accept
configuration command strings from the host computer. These command
strings change the reader’s current configuration, but the changes are not
saved to a configuration file.
For example, to configure the reader to decode Code 93, the host computer
sends this command to a reader application:
$+CF1
The reader application must have been designed to accept command syntax
from the host computer. The reader cannot accept commands when it is at the
DOS prompt. For help using Reader Services, see your JANUS PSK reference
manual.
Editing a Configuration File
A configuration file contains commands that modify the reader’s configuration.
You can manually edit a configuration file to add, delete, or modify the
commands. Choose one of these methods:
• Upload the configuration file to a host computer, edit the file using any
standard ASCII text editor, and download the file to the reader.
• Start Interlnk with the host computer as the client and the reader as the
server. From the host computer, use any standard ASCII text editor to edit
the configuration file on the reader.
• Edit the configuration file on the reader with the EDLIN.EXE editor.
After editing the configuration file, you must configure the reader with the file.
For help, see the next section, “Loading a Configuration File From the DOS
Prompt.”
