Feelin your pain
I feel your pain. I was going to move my plane to the airport yesterday, but the day before I tried to update my D10A and it locked up trying to load checklists. I had to take it out of the panel, and send it back to them. So, I delayed the move to the airport, as it's easier and more comfortable to work under the panel in my warm dry basement. So I'll work on wheel fairings and whatever else I can make up... Hang in there, we are so close. You, closer than me, and your system, much bigger and more complex than mine. But I understand and sympathize completely.

I never had the entire system at 5.2 since the EFIS came at 5.1.1 It was warmer on my first day of working with it when everything first came online. Since then each work session has been cold.
It is all going back Monday as Dynon confirms that something is wrong with at least one of the units. They gave me an RMA. I sure hope they can find it.
This is like buying a 72" HD tv for the Superbowl and having it fail out of the box and sending it in for repair and not getting it back till Memorial Day.

Brian,
Roger all that...figuring you mean you never had the entire system at 5.1.1, since the EFIS came at 5.2. So there's no way to tell if it affects systems that are fully at 5.1.1. I'm thinking of waiting till you hear back from Dynon before I upgrade. 5.2 came out a couple days before I left for the Rocket 100 race, and I didn't want to chance dorking it up. Haven't taken the time to do it yet.
For other readers, is anyone else at 5.2 having similar issues, or is anyone at 5.2 without issues at all...AOK? (Not trying to start a rumor, just investigatin'! 5.2 is probably not the issue, as Brian, it sounds like the problem happened during the upgrade process...at least for the AP-74...and after).
Good news is that Dynon wants to see the units back and are not saying "its the wiring". Good folks, and I'll bet they turn it in time for the "Superbowl"...though that comment sure hits the mark. Hang in there...the home team will win the game in the end!!
Cheers,
Bob

'It's the wiring' is what Dynon told me about my AP74 losing DSAB. I have checked and double checked wiring so I know that's not the issue. The -8 is at the paint shop now so I can't attempt to upgrade to 5.2 or to reload 5.1.1. I'm definitely interested in hearing what Dynon comes up with Brian's stuff.

"It's the wiring" is what Dynon told me when I was pulling my hair out on a DSAB problem when we wired up Louise's panel. And despite wringing things out several times and standing on my head under th epanel....they turned out to be right - a barely recessed socket in a Dsub connector. Very hard to find.

This is an example of the really great GRT feature of recorded data files that can be transported for live data debugging. "We played your demo file. All the data is there, but you have pin A and pin B reversed on connector X on display unit Z. Swap those two pins and it will be fine."

Paul, I brought the units home to box them up and decided to make up a test harness to super duper ensure that the harness in the plane is not the issue.
Guess what..... Same issue showed up shortly after power up.... Units were still cold from the hangar. Once they warmed up. No issue.
This test harness only had power and DSAB leads and the four devices and was powered off the wife's minivan battery.
So I guess that pretty much puts the nail in the coffin for wiring issues.
I have previously double checked all connectors in the plane for pins that were not fully seated. Stein's work was great in my case.

While Dynon does record a ton of data, I do not think they have the ability to play it back. That would be a nice feature to have.

DYNON D180/AP
I HAVE HAD MY UNIT AT DYNON FOR THE PAST 3 WEEKS (THEY RECEIVED IT DEC 21ST). THEY ARE ATTEMPTING TO SOLVE MY DSAB ISSUE. I HAVE A PITCH SERVO ONLY TAPPED INTO MY FLIGHTDECK 180 ON MY RV9A. AFTER ENGAGING THE ALT HOLD IT FAILS AFTER A FEW SECONDS. READING "ERR" AND THE AP DISENGAGES. WOULD SAY LOST DSAB CONNECTION. DID ALL THE DSAB TROUBLE SHOOTING STUFF. ALL OTHER FLIGHT/ENG FUNCTIONS APPEAR NORMAL. THEY FIRST THOUGHT IT WAS IN THE SERVO AND AFTER WAITING ON PARTS AND SOME TESTING FOUND IT TO BE IN THE BOX. TO MAKE A LONG STORY SHORT THEY HAVE BASICALLY REBUILT ALMOST THE ENTIRE D180 UNIT. I STILL HAVE NOT YET RECEIVED MY UNIT BACK, (DUE BACK IN NASHVILLE JAN 15TH). WILL LET YOU KNOW IF PROBLEM RESOLVED AFTER REINSTALL AND TESTING. ADVISE CHECKING WARRANTY DATES (3 YRS) BEFORE PUTTING OFF CONTACTING DYNON TO ADDRESS ISSUE. EMAIL JOE AT JDMEDIC@COMCAST.NET IF YOU HAVE QUESTIONS.

Joe,
Just so you know - posting in all capital letters is considered equivalent to SHOUTING on the internet.
If you are a "challenged" typer, just type in all lower case - we get it that some folks are not as comfortable typing and won't "grade your punctuation."
Thanks!
