Usage

Main View page

This page contains three parameters: Circuit ID, Unit Summary Alarm and Last Trap Since.

General page

On this page, the general parameters of the device are displayed. Some of these parameters can also be set to a preferred value.

The Store Configuration parameter causes the device to store the current modem configuration in a configuration memory location defined by the argument (0 to 9).

The Load Configuration parameter causes the device to retrieve a previously stored modem configuration from the configuration memory location defined by the argument (0 to 9).

Four page buttons are available at the bottom of the page. These each open a pop-up page with additional information regarding the subject described on the page button in question.
