Re: D100, HS34, CNX-80 Question - PROBLEM SOLVED!! Bill - I just looked at your wiring wiki. That is almost exactly the way I have my arinc 429 lines wired up.  The only difference is the pin out from the HS34 TX lines - I call HS34 pins 12&24 TX1 and 13&25 TX 2 but since that is just a...

Re: D100, HS34, CNX-80 Question Phantom - Yes! I can confirm that with my CNX-80 software version 2.00 connected to the Dynon HS34 arinc 429 ports all functions, both GPS and NAV, work and seem to work well. The HS34 does indeed send arinc label 203(pressure alt) and label 204(baro corrected...

Re: D100, HS34, CNX-80 Question Thank you for the reply, According to the install manual the CNX-80 will accept multiple altitude inputs and automatically use valid inputs in a predefined priority sequence, 429, FADC, Serial. I'll keep looking to find the reason before I give up. ~Terry~
