I posted the following on the GRT board but did not get much feedback. I also called GRT but been playing phone tag with them.
1) I am trying to hook up pin 2 (Audio Tone) on my GRT EIS to a GMA 240. Would I hook GRT EIS pin 2 (Audio Tone) to GMA 240 J1 pin 31 (Alert 1 High) or pin 32 (Alert 1 Low)? If not one of those pins, then which one?
2) Can I use pin 25 (4.8V Excitation Out) on the GRT EIS for multiple
accessories? If so, how do I hook those wires together? Power distribution
block?
3) Can I use pin 13 (12 V floscan) and Pin 14 (Fuel Flow floscan) for a Red Cube fuel meter or are those pins only used for a floscan?
4) The PMAG manual says to use only one PMAG for tach information if you have dual PMAGs. The EIS manual says that "Tach 1" source is used first and "Tach 2" is used if no info is available on "Tach 1". Is "Tach 1" the best source for tach data in this particular configuration?
5) What type of accessories did you guys hook up to Aux1-Aux6?
6) What type of switch did you guys use for selection of EFIS or GPS information to the auto pilot?
Thanks for any help you can provide.
