Establishing Communication
Once you’ve defined a connection to your Messenger 570, establishing communications with it is as simple as
clicking on an icon.
Start HyperTerminal by clicking Start, Programs, Accessories and Hyperterminal. Look for the Messenger
570 connection that you've created and click on it.
When HyperTerminal starts, you will see the connection information in the Connect box. Click Dial. You may
hear dialing tones or pulses followed by a “ring” sound, followed by modem tones.
When the Messenger 570 answers, it will prompt you to enter a security code. You must enter a valid security
code within 30 seconds or the Messenger 570 will terminate the connection. If you don’t know the security
code, try the factory default security code, “11111111” (eight ones) followed by Enter.
Once you have gained access, you can enter commands and the Messenger 570 will respond. If you press Enter
at the command prompt, you’ll get a complete listing of commands. The most common commands are INP R
(input status report), ALM R (alarm report) and SEC R (security report).
If HyperTerminal fails to connect, re-check your settings (especially Dialing Properties settings) and try again.
Once a connection is established, the Connect box will close and the main HyperTerminal screen will become
active.
In the following sections of this manual are step-by-step procedures that will help you prepare the Messenger
570 system to work for you - describing how to designate individuals you want to receive alarm messages, set
low and high alarm set-points, etc.
The commands to access the system are simple three-letter codes (e.g. INP = input, ALM = alarm, PHO =
telephone), generally followed by a fourth letter (e.g. R = report, S = set). The system will automatically insert a
blank space between the third and fourth characters.
If an incorrect command is entered, you will receive an “Invalid Command” message.
You may enter a command whenever the “COMMAND>” prompt is displayed.
„ Fax Mode
The Messenger 570 system can send alarm reports directly to a fax machine. Input status reports can also be
sent to a fax machine on a scheduled basis.
Internet Access
An optional internet service is available that will generate detailed daily reports based on information collected by
your Messenger 570 and post those reports to a website. Contact customer service for additional information.
Using the RS-232 Port
Attach a “straight-through” serial cable from your PC’s serial port to the RS-232 port on the side panel of the
Messenger 570 system (next to the phone connector).
Follow the procedure outlined in “Modem Mode” (above) to define a HyperTerminal connection, substituting the
appropriate COM port for the modem in the Connect Using list then click Configure and enter the following
settings:
Bits per second: 38400
Parity:
none
Stop bits: 1
Flow control: Hardware.
