Hi
I suspect that somebody will have to figure out what the 15 pin connector
/ jumper is doing. On previous RFTG units there was a way to re-wire the
crossover interface to fake out the slave detect process. That would let
you run a single GPS equipped box and have it behave correctly. Without
the fake wires trick none of them played nice without the slave being
present.
Yes that seems like it violates the spirit of redundancy. No I didn’t
design it. Yes the guy who did spec it to work that way probably knew a
whole lot more about exactly what they were after in the design.
I suppose the first task would be to figure out if the jumper cable is a
straight through or not….
Bob
