Description of Operation
The Remote Notification option performs three basic functions: Call Answer into
Terminal mode, Call Out to a remote terminal, and Housekeeping. Remote
Notification also allows access to any functions available in the Terminal mode from
a remote computer or terminal.
Call Answer
To use the Call Answer function, the modem is configured to automatically answer
by having the user program the S0 register of the modem to a non-zero number.
When the modem receives a call, the UPS is alerted to wait for a connect signal
from the modem. When the modem answers and finishes handshaking, the UPS
acknowledges the modem connect signal and allows the caller into the Terminal
mode (refer to Chapter 13, “Serial Communications”). In this mode, the user can
request four items and perform one command:
NOTE: The brackets ([ ]) in the following steps indicate standard keyboard
characters.
• Display all screens (^B, ^M, ^P). Press and hold [CTRL], then press [A].
• Display battery test results by pressing and holding [CTRL], then pressing [B].
• Display meters screen by pressing and holding [CTRL], then pressing [M].
• Display event history by pressing and holding [CTRL], then pressing [P].
• Reset Call Out Alarms by pressing and holding [CTRL], then pressing [R].
The Reset Call Out Alarms command causes the UPS to cease Call Out attempts
on a currently active alarm and resets that alarm call. Refer to the “Call Out”
section of this chapter for more information.
Call Out
The Call Out function contains programmable alarms and status events (refer to
Chapter 12, “Responding to System Events”). The notification groups tell the UPS
to notify a remote computer or pager for each selected event. Refer to the
“Configuring the Modem” section of this chapter for information on the modem
configuration. Refer to the “User-Selected Events” section of this chapter to note
which events are designated as group one or two. These events are selected when
the UPS is purchased. The Call Out function activates as follows:
• A UPS alarm or notice occurs that is programmed to cause a Call Out.
• The UPS takes the modem off the hook and sends a command to the modem
to call the notification groups (phone numbers) required. The command sent to
the modem for group one is “ATDTS0” and “ATDTS1” for group two. This
allows the user to program the phone numbers into the modem.
