When a Remote is removed from the group Burst Map, as described in the
section “Remove Timeout” above, entering a value in the Remove Retry Time-
out dialog defines the amount of time (in seconds) that is allowed to pass before
a retry attempt is made to return the removed Remote to the group. The Remote
is re-entered into the burst map cycle; if the Remote does not burst back (ACK)
to the Hub burst controller, it is again removed from the Burst Map.
This allows, again using a mobile Remote as an example, shutting down the
Remote at one location, moving it to a new location, and then automatically re-
establishing a connection to the satellite network.
LNB LO Frequency
This menu item appears for an ECMv2 Hub type only.
This parameter, together with the Satellite Frequency Conversion setting, is crit-
ical for determining RF frequency translations between Hub and Remote offsets
or data spectral inversions. Take care in setting these correctly.
Enter Z at the command prompt and specify the correct LNB Local Oscillator
frequency (MHz) that this Hub unit will be receiving.

This parameter, together with the LNB LO Frequency setting, is critical for
determining RF frequency translations between Hub and Remote offsets or data

Enter F at the command prompt and specify the correct Satellite Frequency
Conversion value (MHz) that this Hub unit requires.
