4.4 Apply Power and Register the SCU
When you apply power, the SCU goes into satellite search mode to acquire the OG2 network. This
activity may take a few minutes to complete. The SCU must complete registration to operate.
Once the SCU synchronizes itself with the network, it sends a registration message to the OG2 network.
The SCU will not register until it has a connection to the satellite. The OG2 network records the
registration message and forwards the registration message to the user’s application. The OG2 network
sends an acknowledgment message over the satellite to the SCU. The SCU is now available to send
and receive messages via satellite.
