No. EMSes always source their own data. Generically, dual D180s isn't a supported configuration. Only one can act as an EMS at a time, basically, unless you double up on all of your engine probes (which isn't practical/possible - you can't split many of your sensor outputs - doing so changes their output, and then both displays are wrong). Customers looking for redundancy with our D100 series products normally go for a D180/D100 combo. A few have done dual D180s, knowing that one of them is just a "standby" EMS that has nothing connected to it. In the event of a failure of a unit, those customers would swap the D37 and D25 to the other EMS to get their EMS back to continue flying to avoid a grounding situation. I can think of maybe one or two cases of someone equipping like this though.
