Getting Started With the Web Interface

5.5.2Modem Setup

The OpenComms EM may be configured to send a numeric message to a pager.

Note: The unit requires an external modem to send pager alerts. The modem port is set at 9600 baud, no parity, 8 data bits and 1 stop bit. For details on connecting the unit to a modem, see 6.1 - Modem Setup and Pinout Guide and 2.3.3 - Connect to a Modem.

To generate automatic pager alerts when a sensor reading crosses a threshold, log in (see 5.1 - Open the Web Interface and Log In) and:

Click on the Alerts tab at the top of the Web interface, as shown below.

Click on the Modem link on the left side of the window. The right side of the window displays setup information for pager alerts, as shown above.

The Call on Error box allows you to enable or disable pager alerts. Click on the Down arrow to the right of the box and select Yes to activate or No to de-activate pager alerts.

If needed, enter numbers in the Access/Country Code box as follows:

Enter any numbers needed to access an outside line—for example, 9—where the call is being placed.

If dialing from outside the U.S., enter the country code of the location where the call is being placed.

Enter numbers to be dialed to reach the pager:

Area Code - Enter the area code of the pager to be dialed.

Phone Number - Enter the pager phone number (the number may be entered with or without spaces or hyphens).

The Message Delay box allows you to specify the amount of time to wait after a connection is established before dialing begins. Click on the Down arrow to the right of the box and select from the list: 5, 10, 15, 20 or 30 seconds.

Click on one of the Dial Using buttons—Toneor Pulse—to indicate the type of connection where the call is being placed.

The Resend box, on the left side of the window, allows you to specify whether the unit will con- tinue to dial the pager at certain intervals as long as the monitored area is in a warning or critical state. Click on the Down arrow to the right of the Resend box and select Never or a time interval: 15 or 30 seconds, 1, 5, 10, 15 or 30 minutes or 1 hour.

Note: The unit will stop attempting pager alerts as soon as it detects a normal state.

Click the Test button to send a test pager message.

Click on the Apply button to keep your changes. (Or click Reset to cancel the changes.)
