Hi, Chris -- Any given S and R numbers on the data pages refer to the same
Beacon. Ie, S36 = R36 for any given page for any given refresh.
However, to keep the data page displays as compact as possible, the data
pages don't display "Blind" Beacons. "Blind" Beacons are Beacons which are
being correctly reported via TCP to the Central Server but which do not see
any other Beacons, nor are they seen *by* any other Beacons via RTP/RTCP.
The B number on the Beacon Info page is a total listing of all Beacons,
including Blind Beacons, since the other information about those Beacons is
needed.
Since Beacons can come and go at will, the actual numbers (Ie, S36, or S14)
don't have any particular meaning, other than that's where that particular
Beacon shows up in the alphabetical listing for that particular refresh.
Let me know if you need any other information.
Cheers!
Mitch
