Configuring the Modem
The Modem dialog box allows you to configure the optional, internal modem or an external modem
that is connected to the static transfer switch. Only one modem can be utilized by the STS2.
The dialog box contains a series of choices that access either a keypad or a secondary dialog to config-
ure settings. Auto dial can also be configured for the modem to be triggered by events, as set up in the
Event Mask choices.
Designated major alarms activate the auto dial modem sequence. Automatic dial attempts are made
to the first number three times, at 30 seconds between attempts. If connection is not established in
that time period, the system automatically rolls over to the second number. Auto dial attempts are
made again three more times at 30 seconds between attempts. The process is repeated until a success-
ful connection is made. Upon successful connection, the system transmits a present status data,
including all active alarms messages. After transmission, the modem automatically hangs up and
returns to the auto-answer mode.
To configure the modem:
1. Select MODEM from the Comm Options menu.
The Modem dialog box is displayed.
