Starter energised

[piersherbert]

Another question if you don't mind. Can you set a widget for STARTER ENERGISED. If so would you need a relay to signal a GP input to ground or can you set the widget to respond to v +ve voltage on the input?

Yep. Any of the GP inputs can read betwen 0-5V, and you can assign widget states to any of those sub-ranges. They'll go to 5V when open, and 0V when grounded. So you can set say 0-2.5V to one state, and 2.5-5V to another, and depending on how it's wired, one of those would be energized and one would not.

And to add, the inputs aren't damaged by voltage below 15V. So you can hook right to a switched 12V source, it will just read 5V when on and 0V when off, not 12V and 0V.

Thanks, From your description it seems I might still need a relay since just connecting a GP input to the starter motor terminal (via fuselink) would result in states "open" or "+12v" both of which are interpreted as +5v.

Perhaps it could be done with a couple of high value resistors in series between the starter motor (signal) and ground. For equal value resistors the centre tap would give +6v when starter energised and 0v when not?

If this would work, what resistor values would you recommend (or what is the full resistance across the potentiometers used for flap, trim etc.)?

With the little round annunciator light widgets, can you set any label / text caption of your choice?

It will work hooked right to the starter motor terminal. The other side of that terminal is hooked to ground, via the low resistance inside the starter. Thus this is actually ground when off and +12V when on.

You can label the states on the contact widget the way you want.

Ok, thanks for clarifying that.
