This may help someone figure out my problem:

Don, have you updated the transponder?

Training with Jetguy next week! :D

If I remember correctly (doubtful) you need to download SkyView 14.2 System Software Update (84.4mb .dup file) from Dynon. When you insert the drive into Skyview you should see several files and one should be a firmware update for the transponder. Load it by directions in installation manual.
You did have the avionics switch on?
Someone else jump in if I am going down the wrong path here.

From the other thread:
Remove I am baffled, my GPS has always worked just fine, even when upgraded from the 250 to the 2020. Suddenly I have a "no GPS source" red x instead of maps. The aircraft or the components have not moved even an inch since long time working just fine. I just upgraded from 14.0 to 14.2, but it was doing that on 14.0 previously. Can the GPS antenna be "switched off" or something?

So a few things here: First, you've got a few errors that need to be taken care of (all are documented in the installation manual). The standby network error implies that the SkyView Network wiring between at least two components is suspect.

As for the GPS position source - have you checked the serial port settings in setup? That would be the first place to look to make sure that somehow the SV-GPS-2020 or -250 hasn't somehow changed in its configuration.

I bet you hate us guys that cannot seem to figure out how Skyview works. Anyhow, here is the Network error reason, seems strange that the same two wires would be unplugged on both servos, right?

And here we see the GPS 2020 is not transmitting or receiving, like it got unplugged or something?

So it's hard to perfectly diagnose without knowing the way the system wiring is laid out, but the first picture likely indicates a problem in the wire on either pins 4 or 8 UPSTREAM of the servo (or a problem in the wiring going to both of them if they don't share a common upstream component). Is there a common cable or connector that goes to them that is then split?

Or, is there a chance this aircraft had D10/D100 series avionics in it previously? When wired for that system, there could be - in some installation - only one pair of those network wires.

On the second picture one. It's either unplugged in some way or not working. I'd check the power, ground and GPS transmit wire. It's most likely to be one of those. We don't transmit back to the GPS, so the TX line on that page is expected to be blank. It could conceivably be the GPS itself, but the SV-GPS-2020 has been super reliable in the field so far.

Thanks a bunch Dynon, that gives me some great guidance to start looking for the problem.

In researching my setup, I discovered I have my SL30 installed on port 1 and also on port 4, dunno how that happened. Port 4 seems active and working, port 1 does not. Now how do I delete one of them?

Choose "None" or whatever should be on the serial port. It's shown on your second screenshot.

My GPS issue was easily solved as well. In tracing the wires, I found the lead not plugged into Vans box! I suspect I went for a screwdriver to fasten it in - and the phone rang! Working fine again now.
