Lost the data input coming from my Garmin 696

[Rocky_W]

Hello

I had GPS data from my Garmin 696 feed into my Dynon Skyview which allowed me to fly a route on the autopilot. The GPS data was also used to fly a trach on my autopilot.

On a recent flight I noticed that the data from the 696 is no longer showing on my Skyview screen and I could not use my autopilot, as my autopilot is using the GPS data from the 696. I then checked the 696 and I found that is had lost all historic data. I assume I must have drained the battery by mistake. I set up the 696 again and configured the Interface as NMEA Out/In and the BAUD rate as Normal which should give a BAUD rate of 4800. I found this on one of the forums.

Then in the Skyview it is set up under the serial port setup as port 3. I've made sure that the Navigation Source Display is (Not set) and Serial Out Device is set to None. On the Serial in function I have GPS 1 - Serial port 3 and POS 1 - Serial port 5.

On the setup screen on the Skyview it is showing (but it is grey so I can't change it) that the BAUD rate in / out is 9600. So I also tried setting the Garmin's BAUD rate as Fast. That made no difference.

I have not flown since changing the settings, but I get no distance information on the Skyview screen with a leg on a programmed route activated on the 696 and the distance to the next way point showing on the Garmin (but not on the Skyview).

I had this issue before just after buying my aircraft, but I can't remember how I resolved the issue. Any advice welcome. Thanks!

Try 9600 baud on the 696. I've seen some people make that work. Might have been a 796 though....... Wouldn't hurt to try it in any case.

I managed to work it out through the forum. The main mistake I made was on the 696 I set only NMEA Out/In with normal BAUD rate but in this setting the BAUD rate drops to 4800 (even as set as Normal). So I set the 696 to In/NMEA & VHF Out with Normal. The Skyview settings were as above.

This is from Dynon staff on another thread which is applicable to the 696:

On SkyView, you need to have the serial port that's physically connected to the 796 set to the device. I think the 796 might not be listed but al of the X96 units are the same as far as SkyView is concerned - so just choose 695/696 for example. You'll also need to set the serial in function - typically to GPS 1 on most systems.

On the Garmin side, you need to set the serial data output to one of the formats that outputs NMEA at 9600 baud. Also make sure that the data rate setting in the advanced nmea setup is set to normal, not fast, as fast omits some of the sentences that SkyView needs.

Once the above two things are done you should be able to go to the serial port setup for that device and see both the "RX COUNTER" increasing rapidly and the "GOOD SENTENCES" line increasing somewhat slower.

That's basically it. Select the device on the HSI, and you should see the 796's course and other information on the PFD.
