To set up PRISM
If you are going to use PRISM you must first install the PRISM server software from Cobham
SATCOM, set up the server and then set up the EXPLORER 540. For general information on
PRISM, see EXPLORER 540 operation in Cellular modem preferred (PRISM) mode on
page 97. For details on setup with cellular modem, see To set up the EXPLORER 540 for
cellular operation on page 93.
To configure the EXPLORER 540 for PRISM, do as follows:
1. In the Terminal settings page, under Connection, select Cellular modem preferred
(PRISM).
2. In the same page, locate the PRISM section.
3. Type in the Shared authentication key.
4. Type in the IP address of the PRISM server.
5. Type in the Server port number.
6. Type in the ping interval for BGAN and cellular modem respectively.
7. Click Save.
To enable or disable Network Service Device (NSD)
If you have an Inmarsat GX system together with your EXPLORER 540 and you want to use the
EXPLORER 540 (BGAN) as backup when the GX service is not available, you can acquire a
Network Service Device from Inmarsat. The NSD will use a PPPoE connection to allow your
system to use the BGAN service when your system is out of GX spot beam coverage. To enable
NSD, do as follows:
1. In the Terminal settings page, locate the NSD section.
2. Select Enable if you want to use an NSD with your EXPLORER 540.
For information on PPPoE, see PPPoE (Point-to-Point Protocol over Ethernet), BGAN only on
page 38.
The ping interval for PRISM overrules any ping interval entered for the
Connection Watchdog. The Terminal Watchdog, however, will continue to use
the entered Watchdog interval independent of the interval entered for PRISM.
