The band data is connected to both units in parallel.
The RF Path between the two filters is in series.

Subject: Whither error Array band pass filter wiring?
Bob, W5OV advises to wire the AS419 and the AS419W from Array Solutions so
that the band data from a Yaesu/K3 is IN PARALLEL with the two units.
However, the link below states to wire the two units IN SERIES.
This latter info is what stopped me to wonder if the data socket is the way
to get the two units in Series or use the networking ??? A simple mind is
confused, 73, Charly
