I have a D100, D10A, EMS120, SV52 and an HS34 in my Lancair ES. This system has been functioning perfectly for about 1000 hours. I recently flew through a highly charged cloud and experience massive electrostatic interference. Since then the system cannot find the HS34 on the DSAB all other...

Good input. Thanks Thomas, I'll look for stuff that's not grounded, probably a lot. Thanks again Pat

I have a Lancair ES, a glass fiber airframe. My panel comprises a D100, D10A HS34, D120 and a SV42. All works perfectly and is a pleasure to fly with, however on more than one occasion I have experienced malfunctions when flying in the vicinity of static laden clouds. This has been an issue...

Lot of work done. I tried terminating the DSAB with 150 Ohm resistors. The bus layout is such that the master (D100) and three slaves (D10A, D120 and HS34) are all co-located, within no more than 18 inches from each other. The SV42 is about 10 feet of cable away from the rest. The attached...

Got my servo back from Dynon a week ago, thanks for the prompt response! The bad news is that the problem wasn't solved. i.e. doesn't join the network, it did once however and never again. Today I'll take out the scope and have a look at the waveforms, it could be reflections due to an...

Thanks. I'll call on Tuesday (1/26) afternoon. Pat

Help?!?! Anyone? Pat

Power is from a bus through a fuse through a panel mounted switch and then to the servo, total length about 7 feet of 20AWG. Ground is to a centrally mounted grounding bus directly from the servo, also about 7 feet of 20AWG. The DSAB signals are routed through a shielded twisted pair, the...

Looked at the version on the EFIS and no hint of a servo. Picture attached. What next? Pat

The first two questions are addressed in reply #2 above 1. Configuration occurs normally with and without the servo attached, i.e. all 4 devices (D100, D10A, D120 and HS34) are found in both cases. 2. I have tried that without success. 3. Did not try detecting the firmware, I can try that this...

OK. Finally got time to work on the problem. I tried swapping the DSAB wires, no joy. I then traced the wires and swapped them back again as they were correct initially. After about 6-7 tries the DSAB configuration found the autopilot, once! After repeated subsequent attempts, using different...

Again thanks for the prompt response. Dynon support is A1. Thanks for the clarification, I could not come up with a scenario that explained the behavior. I can now proceed with confidence. I'll let you know if there is a further issue with the SV42. Best Pat

Thanks for the prompt response. I didn't make the situation clear in the initial post. 1. I installed and connected the SV42. turned on the power to all avionics. Navigated to the DSAB menu on the DSAB Master (D100) and went to "configure" said "yes" The unit paused for about 20 seconds and...

I have just completed the installation (addition) of an SV42 to my (already installed) D100-D10A-HS34-D120 system. After firing it up I attempted to configure the DSAB and it found the four original device and not the SV42. After a short delay a nice lady told me I had a "DSAB Error" and all the...

I have a D110, D10A D130 and HS34 installation. I upgraded the firmware and now my D10A shows a slight turn to the right during taxi and slow aileron rolls to the right during level flight. Coincidence? Or a bug? The D100 and all the rest work normally.

Re: Problems with VOR dispay on HSI page using HS3 Latest update. I thought everything was working, but it turned out to very intermittent. Sometimes it worked and sometimes it didn't, about 20% of thime it worked and 80% it didn't. Just before ripping the wiring out of the panel I decided to...

Re: Problems with VOR dispay on HSI page using HS3 It was the SDI setting on the VOR/LOC/GS ARINC 429 CONFIG page. I had it set to VOR/ILS1 instead of of COMMON. This is a really embarrassing admission. Thanks once again. Pat
