MCNConfig Program: Master-Sub Comparator Configuration
93 68-11824-210
Equipment-Centric View
The following diagram shows an equipment-centric view of the system described above. It has the
following:
•
A display for each receiver for each Sub Comparator
•
A display for the Master comparator, showing each of the Sub Comparators feeding it.
It does not use the special Master-Sub Comparator features in MCNRCD (discussed below).
Master Comparator
Sub A Rx
Sub B Rx
Sub C Vote
Sub D Rx
Sub Comparator A Sub Comparator B Sub Comparator C Sub Comparator D-1 Sub Comparator D-2
Site 1 Site 9 Site 17 Rx Site 25 Site 33
Site 2 Rx Site 10 Site 18 Vote Site 26 Site 34
Site 3 Rx Site 11 Rx Site 19 Rx Site 27 Vote Site 35 Dis
Site 4 Vote Site 12 Site 20 Site 28 Rx Site 36
Site 5 Rx Site 13 Site 21 Rx Site 29 Site 37
Site 6 Rx Site 14 Vote Site 22 Site 30 Site 38
Site 7 Site 15 Rx Site 23 Rx Site 31 Site 39
Site 8 Dis Site 16 Site 24 Site 32 Site 40
The above display indicates:
•
The Master Comparator is voting Sub Comparator C.
•
There are other Vote indications on Sub A, Sub B, Sub C, and Sub D.
Each comparator is shown as an independent comparator (although they are actually physically
connected in a Master-Sub configuration).
To determine which audio is being heard by a dispatcher, you would have to go through a two-stage
process:
1. Determine that the Master Comparator is voting Sub Comparator C
2. Sub Comparator C is voting Site 18
In other words, there is no immediate direct indication of which site’s audio is being heard by the
dispatcher. The Votes on Sites 4, 14, and 27 from Sub Comparators A, B, & D are not the signal being
used by the Master Comparator at the moment, even though they have a “Vote” indication. This can be
very confusing to a dispatcher
However, the equipment-centric display could be useful for a technician who is troubleshooting the
system. If, for example, a Vote is stuck on a Sub Comparator, it would be readily apparent on this
screen.
