Master device - what does it do?

[captflyby 2]

Hi, can someone explain what the rxpGTN "master device" settings does in the plugins when enabled?

Thank you.

Thank you.

The navigation master device is the one that steers the autopilot in GPS mode..

So by selecting this, I use only the rxpGTN as my navigational reference coupled to the autopilot.

When the GTN is set to GPS mode, yes.

When the GTN is set to VLOC mode, the NAV1 radio steers the autopilot.

In both cases: with the autopilot set to NAV.

It is a little broader than this though and further explained in the RXP GTN/GNS V2 User's Manual.

TL;DR: whenever a shared resource, the master device is the one 'owning' it.
