I haven't been keeping up on the Dynon ADS-B release. Anyone know why the new product is single channel only and not the other manufacturers are shipping dual channel units? I would be interested in the underlying reasons for this decision; what are the pros and cons of doing it this way...

Just as another data point. I have dual P-Mags, SV1000, O-360 on my -9A. I also ran both tach leads frrom the P-Mags to the appropriate pins on the EMS-220 37-pin connector and got erratic RPM readings with 2 pluses/rev. I deleted the Left P-Mag tach lead from the setup screen and everything...

I go the other way, my Red Cube number is 65,000 and still closing in on the "perfect" number. Dan

Took off yesterday on a 30 min flight to nearby airport. The SV1000 reported that the "GPS POS1 FAIL" via the caution button. Sure enough no MAP, SYN VIS, or anything else GPS dependant. The PDF and ENG displays were normal. Since I had the iFy 720, I contiued to nearby airport. On restart...

I just upgraded to one SV 1000 after flying behind the D-180 and D-100 7" units for 5 years in my RV-9A. I can display all 3 screens (40% PDF, 40% Map and 20% EMS) on the SV1000 and my 66 year old eyes are more than adequate. Bigger is better. Dan

Have any of you who have the SV series upgraded from a D180 to the SV series? I am looking for the changes in wiring needed to have the plug and play harnesses be correct for the SV EMS. I know that I have to reroute the OAT from GP1 on the D-180 to the SV ADAHARS and apply voltage to pin 1 of...

ColinG: I have the same setup on my 0-360 Lyc and a D-180. I ran the tach outputs directly from the P-Mag tach outputs to the D-180 tach inputs, no resisters. Works fine with ACS ignition switch. Dan.

Thanks for the info, well stated and comprehensive. One more question, will I have to add an on/off switch on the P-mag side to do the pre-takeoff mag check. Or will it be the same procedure as now with standard mags and ACS key switch? Thanks, Dan

Guys: I have researched the forums for an answer, it is not there or I missed it. I am considering a P-Mag for the right side of my Lyc O-360 powered -9A and need to know if the newer 114 P-Mag is compatible with the D-180. Ideally, I would like to simply hook the existing right P-lead to the...

Would the orientation of the pressure sensor have any effect on the rotating arm thingy? I have mine mounted normally on Van's manifold in the horizontal position. Would rotating it a quarter turn have an effect? Dan

RV-9A with O-180, Dynon 180 and 100, TT DII VSG, Garmin radio stack.

Ray: Maybe I can help, no guarantee. I have a 300XL, same as 250XL but with a bit more memory. Pin 19 is not the pin I used, it is the other RS 232 out, Pin 20 something. I split it to drive both the D-180/100 and the TT autopilot. I used Pin 19 to drive my APRS. I hope this info is...

Guys: Which wire on the GNS 300XL is preferred for GPS input to the D-180, pin 19 or 24? Thanks, Dan

Will the Zaon PCAS systems (or other brands) display on the skyview? Santa Claus is coming and in order to get my letter to the North Pole sent in time, I would like to know what TCAS products will be most likely compatible. Thanks, Dan.

Dynon: On the last leg of my trip, the "P" in PSI did not flash. So this is now officially "an intermittent problem". I will try and troubleshoot the problem on the next flights and forward the info. Thanks, Dan.

Dynon Dudes: I have been on the annual tour of the US to visit relatives and friends, 32 hours in 15 days. Today, I noticed that the top half of the "P" in "PSI" fuel pressure was flashing on the D100. The lower leg of the "P" was fine but the upper half was flashing. The "S and I" were...

Dynon dudes:  Will the NexGen units have USB or SD card reader capability for software/firmware updates and down loadiing data logging info.  Much easier to carry the NexGen USB or SD card to the computer than to carry the computer to the unit.  Dan

I updated yesterday to 5.1 from 5.1A20, beta program to figure out why clock/internal battery/ship battery wrong or drained. I have a D180 as master and a D100 as slave. I flew today for two hours and noted the following problems: first, on D180/100 power up the clock was wrong, I reset it...

Re: Erratic Fuel Flow (FF)  reading with alarm I don't have a shroud but I do have a cooling air line on the fuel pump. The fuel lines are fire sleeved. I have not considered the possiblility of vapor lock. I will try to replicate the high FF in the pattern and then use the boost pump to see...
