NAV select information
Thanks, guys. I did discuss the wiring with Sid at Trio, and he told me I clould use a DPTD (that's correct) switch to select the nav data stream for the Trio between the EFIS GPS and the Mini-X GPS, thusly:
One pole selects the serial output from one device or the other, the second pole selects the ARINC 429 "A" from the HXr, vs. none from the Mini, while the ARINC 429 "B" is hardwired to the Trio at all times. Without both sides of the ARINC data, the Trio defaults to whatever else is available without the need to break both ARINC poles.
Also, the Trio will auto-sync to 4800 or 9600 baud RS-232 as well as to ARINC hi or low speed data, per the Trio guys.
I appreciate the advice about fully programming the EFIS for autopilot commands. After I install the Trio and fly it in the old panel a few times, when I put in the HXr I will make it the default for autopilot control. That way Iwill know both systems even if I always default to the easier EFIS controls.
At least that's my current thinking.
