6. Clear the Debug Mode checkbox unless you are instructed by SerVision technical support staff to select it.

7. If you want the unit to test the cellular network connection periodically, select Verify. The fields required to

configure this option are added to the screen.

Figure 44: Verification settings

Fill in the fields as follows:

Field

Description

Verification

Server

Specify the IP address or hostname of the server that the unit should ping in order to test

the connection. This can be any device on the network whose connection you want to test.

For example, if you want to ensure that the unit is connected to the internet, enter the URL

of a server that can only be accessed via the internet, such as www.google.com.

If the verification server does not respond to the ping, the unit attempts to reconnect to the

cellular network. It continues to try to connect periodically, at the interval specified, until it

succeeds.

Note: For additional information about the ping command, see

Ping

, page 141.

Interval

Fill in the frequency of the verification tests, in seconds.

8. Click Update. The settings are immediately implemented on the unit. If a modem is connected to the unit, and

the configuration settings are correct, the unit attempts to connect to the cellular network through the modem.

9. Save the settings to implement them permanently (see Saving Configuration Changes, page 125). It is not

necessary to restart the system.

CVG-M

Modem settings configure the CVG-M to use the built-in cellular GSM modem to connect to a cellular network.

The settings are implemented if a SIM card is installed in the unit. Before you configure the modem, ask your

cellular supplier for the correct settings for the SIM card you are planning to use.

NOTE: If the SIM card requires a PIN, configure the modem settings as described below before you insert the

SIM card into the unit. Otherwise, the unit may attempt to use the SIM card to connect to the network

with an incorrect PIN. Attempts to use the SIM with an invalid PIN may cause the SIM card to be

locked.

After you configure the modem settings, you must save them and restart the unit. From this point on, the CVG-M

automatically attempts to establish a connection to a cellular network whenever it is not connected to a cable-based

network.

NOTE: For additional information about selecting and installing a SIM card, and about CVG-M network

connections in general, please refer to the installation guide.
