Communications
This section describes the procedure for establishing communication with a
Messenger 570 system. It includes details on how to use the RS-232 port for
local or satellite communication, a phone line for data, voice, pager and fax
communication, and how to put data into the web.
Using a Phone Line
Data, voice, pager or fax? It’s your decision!
The Messenger 570 system can communicate over a standard phone line with a computer, pager, or facsimile
machine. It also offers a powerful, easy-to-use voice mode for ready-access to information from your equipment
anytime, from any standard telephone.
The data mode will allow you to review inputs, set up and reconfigure any Messenger 570 system from a remote
location, retrieve stored information, and perform diagnostics from your PC.
The voice mode offers the convenience of inquiry into condition status from any standard telephone, and provides a
high-quality, clear, consistent voice without the need for set up, programming, or recording.
The Messenger 570 can also be programmed to call a facsimile machine at predetermined times and deliver a
concise status report.

The Messenger 570 will respond to your call by generating a "bong" sound, followed by a few
seconds of silence. If you press the # key on your touch-tone phone during the time of silence, the
system will immediately switch to voice mode. Otherwise, the system will begin to generate a
carrier tone
− indicating that the system is attempting to communicate with a data terminal. The
tone will eventually stop after a few seconds and the Messenger 570 will again switch to voice
mode and speak in a synthesized voice:
“Hello, this is telephone number five, five, five, one, two, one, two. Enter security code.”
Enter your eight-digit security code on the touch-tone keypad (initially set at the factory to “1, 1, 1, 1,
1, 1, 1, 1). You do not have to press # after the eight digits are entered. The Messenger 570 system will
respond “OK.”
