State Packets

Certus supports a ANPP number of packets providing extensive functionality. However for the majority of users the easiest approach is to configure Certus using the web UI or Certus Manager software and then support only the single system state packet shown in System State Packet. Advanced functionality can be added as required through the other packets.

This section covers the following topics:
