Configuration through the Java applet interface

Configuration through the Java applet interface
A Java applet interface is available as an alternative device interface.
Accessing the Java applet interface
The Java Applet interface can be temporarily launched as a device interface, or can be set as the
default interface. In some cases, a system administrator may have already set it as the default.
To launch the Java Applet interface, go to the Home page of the web interface. Under User
Interface, click the Launch button to launch the Java applet.
To set the Java applet as the default device interface, click the Set as Default button.
Differences between web and Java applet interfaces
The Java applet interface differs from the web interface in these areas:
 While the web interface runs directly on the device, the Java applet runs remotely. This
means when the Java applet launches, all device settings are updated from the device
and stored in memory. These are the settings shown when clicking on a configuration
choice or clicking Cancel.
 Because the Java applet runs remotely, it is not always aware when settings have been
changed by other users. Therefore, it is sometimes necessary to refresh the applet to
retrieve those settings.
 There are fewer configuration options under Configuration: Network, Serial Ports,
GPIO, and Security. Alarm configuration is organized under Management, and there
is no System configuration option.
 Some features have limited configuration settings. For example, port profiles are not
available in the Serial Ports settings.
 The button for saving configuration settings is labeled Save rather than Apply, and there
are additional buttons: Cancel and Apply.
 A status pane logs all activities in a session.
 Online help available for the applet screens is limited. As needed, switch to the web
interface and review the online help for the screens in that interface.
System requirements
Using the Java applet interface requires that the Sun Java Runtime environment be loaded on the
computer used to configure, monitor, and administer the Digi device.
