Cables to Go CDM-570L manual Group ID, Low Data Rate Fast Acquisition, Burstmap Multicast IP

NOTE

Vipersat Configuration

This mode is designed to accommodate the needs of a remote which will not be continuously connected to the network, but which has the need to be able to make an on-demand connection when required, such as a mobile remote.

Note that the switch occurs as soon as the hub receives an STDMA ACK even though there may not be traffic at that time. The persistence of the link will be determined by the unit’s flag settings.

Refer to Appendix B, "Automatic Switching" for details on this switching mode.

Group ID

The STDMA group ID number defines a group of equipment which will respond to the output of the burst controller. This group is addressable within a network which, in turn, is defined by the network ID number assigned to the CDM-570/570L.

Note: The STDMA group number and the network ID are independent. There can be multiple STDMA groups within a single network.
