A couple of things I've picked up which may not be documented (I'll admit to not reading everything): 1) If you hook a Garmin Aera configured as a secondary position source to the SV and use the Aera to select airports or airport frequencies, these will be received by the SV and then pushed to...

Sometimes it's a configuration problem! I found that the pin was not configured, so hopefully that's the fix. Thanks, Vern

I have a new install, with SV 6.0 software; Standard magneto on left, Electroair on right, IO-540 D4A5. Tach indicates properly with Electroair, but drops to zero when Electroair is turned off. Magneto is still operating fine. Checked the data log, it shows identical rpm on both L and R...

This is a tad premature, but this fall there will an open-source trim controller design released from MakerPlane that can be programmed to talk to a SkyView and sniff the data streams. It's feasible, with some firmware development, to make this into an auto-trim device. It would be a lot...

Here is a solution to the problem if you are using the RP3 LED bargraph indicator from Ray Allen.  This circuit buffers and amplifies the RP3 potentiometer voltage so that it is independent of the SkyView. Power is provided by the SkyView EMS 5V reference, so their is no danger of overdriving...

I have a servo motor controller design that is capable of taking autotrim commands from any compatible EFIS. I have developed a protocol for this that is easy for Dynon to implement, but I would be willing to work with anything Dynon can throw at me. This controller will be released as an...

I have a request: The boot-up procedure for the SV system is reminiscent of the early days of Windows. Is it possible to have a more dignified boot-up? Right now, it (figuratively) coughs and sputters like a '67 Falcon. It does not convey the look and feel of a piece of quality equipment...

Sounds feasible. What I ended up doing is programming the flaps to 0 and 1 (degrees), so now my display shows the flaps arc with a 0 or a 1... kind of a binary representation, which is acceptable for me.

I have a microswitch that simply indicates when the flaps are deployed. I input this to the ems via a CONTACT widget. Is there any way to use a CONTACT input as a parameter for the flaps overspeed alarm or am I stuck with just using the POSITION parameter? I can kludge it by calibrating the...

SkyView audio noise eliminated! I have found the solution for elimination of the SkyView system audio noise.  It includes Dynon's recommendations on adjusting audio levels, plus grounding issues.  Rather than replicate the discussion, please go to...

Well, the plot thickens.  This is now happening every time I power up. I connected the EMS directly to the SV-D1000, with no other devices connected in the system.  Here's what I found: On a cold power-up, the EMS is not recognized and the EMS lamp is solid red. On a warm power-up (power off...

I suspect that I'm getting reflections off of an unterminate SVN cable. Thismproblem started when I removed a servo for service. I will rig a connector with termination resistors and try again.

Twice today, I powered up my system and the Skyview could not find the EMS. Cycling the power worked. This is the first time I've seen this. Aircraft is not yet flying. I will check out all of the connectors and d-sub pins. I did find a bad SVN cable once before (pin not fully inserted)...

My suggestion would be to jumper your two fuel level inputs over to two enhanced inputs. Define the enhanced inputs as fuel level (capacitive type). Calibrate your main floats in level flight position and the enhanced inputs on the ground. Should work, but I haven't tested it. Vern

It turns out that you cannot use an arbitrary file name for the definition file. It's safe to use the default filename when you "save as", then edit the contents. Arbitrary file names are not recognized by Skyview, such as "mysensor.sfg". Took me a while to figure this out. V

... I knew you'd ask.  The diagram is idealized.  The actual circuit is here: IL-4A. I've put the diodes in, everything is good now.  I had this problem years ago with another engine monitor and had the same fix.  Too bad you can't make every input type C.  The reason I have both annunciators...

I have a situation where I am overdriving type A inputs on the EMS.  In this situation (diagram A below), current is being sunk by the EMS input, causing the LED to glow faintly. Diagram B is my proposed fix, but is it also possible to just progam the input pull-up to 200K?  I'm worried about...

I've read the white paper that describes the work-around for the pitot-static testing bug. In Canada, we need to have a static system and transponder certification every two years.  This means that a certified avionics shop does the testing.  I've had this performed several times. It is...

Ahhh.. not clear from your documentation that GPS position data is passed over the #1 link.  Thanks for the clarification. Vern

#1 - SV-XPNDR-261 #2 - SV-XPNDR-261 GPS position (output only) and panel port #3 - Garmin SL30 Nav In and Comm Out (waiting for Dynon to Support) #4 - Garmin Aera 500 (input only) as alternate GPS device #5 - SV-GPS-250 It's possible to recover port #2 and repurpose for ADS-B if GPS data from a...
