WIRING A Garmin 796 to Skyview

[Bruno]

Hello Support

I just bought a new Garmin 796 to replace an AVMAP IV and I wondering how I should wired it to my Skyview so it can be use to drive the autopilot?

Any special ways this should be done?

Also are there any news ( updates) coming to Skyview prior to Oshkosh?...Like a SV-700 Touch etc...

Thanks

Bruno

It's pretty straightforward - you'll need one of the cables from Garmin that breaks out the serial data output, and that gets connected to one of SkyView's five available serial ports. Make sure the NMEA data rate on the x96 is set to NORMAL, not FAST (but it should be at 9600 baud). You'll set the serial input on SkyView to the Garmin format. Then, once you have a flight plan on that device, you can select it on the HSI and the autopilot will follow it. But, all that said, SkyView's own mapping and flight planner are really the best way to drive the autopilot - there's no real need to drive it from an external portable.

Hello Support

I tried everything suggested to hooked up my 796 to my Skyview but it still doesn't show on the SV.

Just to confirm the connection mine is hooked up like this

Connected to Serial Port: 1

796 Tx to SV RX

796 RX  to SV TX

The rest is as per your suggestions above but no joy so far..

Anything else I could try???

Thanks

What are you seeing on the serial port 1 page on SkyView, particularly on the RX counter, good sentences, and the group errors lines? Do you have the Serial in device set to Garmin 796 (actually there is no 796 setting - 696 will work just fine though). What do you have the baud rate set to?

Hello Support

I have a screenshot of my setting but I can't upload it here....

The device is set to : 696 ( as suggested by Support )

Serial IN : GPS 1

Baud rate : 9600

Serial OUT : NMEA  OUT FULL

RX Counter :6976

TX   ''        :569155

Good Sentences  : Zéro

Group Error :  89

I could include a picture if I knew how??

Thanks

Bruno

I would love to know the answer to this as a friend I am helping is seeing exactly the same problem.

Cheers

So serial out need not be set unless you want SkyView to send NMEA GPS information to some other device. But this wouldn't inhibit things from working.

The fact that you have an RX counter is good - it means that we're seeing data on the serial port. However, seeing a number that low compared to the transmit side makes me think that your 796 might not be set to the right output format. What are all of your serial port settings on it? Note that in the advanced NMEA setup on the 796, you want the data rate set to Normal, not fast.

Hello Support

Thanks for the reply

Too bad I ddin't read this post this morning as I spent the day working on the aircraft and could have got the info.

I know for sure that the Data rate is set to Normal not fast as suggested by you a while back.

''unless you want SkyView to send NMEA GPS information to some other device.''

''What are all of your serial port settings on it''

There are 2 serial port on the 796 and the first one is used for a Garmin GDL 39 3D
--------------------------------------------------------------
I would like the 796 connected to my Skyview to be used as a back up if required.I use the Skyview GPS and a King GPS which are both hooked up to the Skyview.

Next time I'm at the hangar I'll get the required info and report back

Thanks again

Was this issue ever resolved? If so, what are the correct settings to connect a Garmin 796 to a SkyView, as I am having the same problem. The SkyView is not getting data from my 796.

 

[Dynon]

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.

Question on the last sentence. I seem to recall that the Skyview would NOT provide vertical guidance on the HSI unlike an external portable such as my 496.

 

[Dynon]

Yeah, that's true. The guidance that the x96 provides will be shown as a "needle" which SkyView's AP can follow. SkyView's own vertical speed required accomplishes the same thing, but you'll put the autopilot in VS mode instead and set it to the number SkyView provides. Same result, slightly different method. And yes, there's room for improvement here.

Fair enough. I hoped that maybe my info was out of date.

Thanks for the candid and prompt response!
