Configure Hub Unit
Once all active Remotes have been configured to ECMv2/Online state, the next
step is to configure the ECM Hub Channel Controller, which can be the demod-
ulator on either a CDM-570 or a CDD-56X.
Caution: If a separate controller is in use while the current STDMA unit(s) are
running, make absolutely sure that the Group ID is unique from what
is currently configured in the running STDMA's. The multicast IP
address can be the same; this is not a problem.
Ensure that the Low Data Rate Fast Acquisition feature is disabled.
Set the Preamble accordingly. If unsure, contact CTAC for the
correct value to match the active configuration.
1. From the CLI Main Menu, navigate to Vipersat configuration > STDMA
Mode screen.
2. Enter T at the command prompt for Hub Type, and then enter 6 to select
ECMv2 (figure D-2).
