Support of Garmin GTN650 by D180/HS34

[mhubel]

Is it known if the Garmin GTN650 will interface properly with a D180/HS34? Are new installation instruction available for the GTN650?

 

[mhubel]

Is there some other place I should ask the question about the Garman GRN650?

 

[dynonsupport]

Nope. Sorry, this is the spot. It definitely works with SkyView, but we're still working on determining compatibility with our first generation products. Some things in the output changed subtly. I'll try to get an answer on this shortly.

 

[dynonsupport]

We've confirmed that the GTN series is compatible with our D10/D100 series products (using the HS34 for full ARINC compatibility)

I have a 10" Skyview with an SL30 Nav Com. If I install an IFR GPS, such as the Garmin GTN650, will I need a separate Omni for the SL30, or will I simply use the GPS and Nav Com together on the RMI indicator? Will the GTN650 fully integrate and fly the Skyview autopilot (at least in lateral mode)? Any other peculiar install issues for the Garmin 650??

Also, are there any plans to allow Skyview user to adjust the font size, or "declutter" unneeded intersections on the Map page? Both of these capabilities would make the screen a bit more readable.

Thanks for building a great product!!

No, you don't need a separate omni or HSI. SkyView can do it all.

Yes, SkyView's autopilot can fly the airplane based on the lateral navigation of the IFR GPS, with vertical nav planned as a future "advanced autopilot" feature.

Everything's straight forward with the GTN integration. See the installation guide on our website for the page or so of details.

I have a GTN650 and a HS34/D10A, but can't seem to get the NAV/LOC functionality on the HSI page. Where is there documentation for the pin outs and GTN setup pages? Right now I'm using the Skyview D25 pinout and setup as a guess.

And yes, the GTN will tune and identify a VOR... But the HSI can't see it. HSI sees the GPS flight plan just fine though.

What happens when you hit NAVSRC on the HS34? Does it cycle through both the NAV radio side (green light and HSI) and GPS (magenta light and HSI)? You should have your GTN's setup software setup as specified in SkyView's manual. The wiring is the same too, except the pin 8>3 connection for the serial port wouldn't be used on the HS34. On the HS34/D10A software side, here's what you want those setup pages to look like: http://wiki.dynonavionics.com/Garmin_GTN_650

 

[Toobuilder]

The HSI toggles between GPS1, GPS2, NAV, and a "basic" (magnetic?) page when I hit the NAV SRC button.  The unit is wired and setup according to the SV manual, and so is the GTN setup.

Further, the BRG SRC button will allow me to select the 2 GPS's (even though I only have the 650 on line) and the NAV.  The Bearing indicator only comes alive with the GPS1 (the 650).

And yes, the D-10/HS34 ARINC page is configured as shown in the link above.

 

[Dynon]

What do you see on the HSI page when you have it set to NAV? Can you snap a pic?

Do both GPS choices "work", or only one of them? If the latter, you may have one of the local serial ports or the HS34's serial ports set to a GPS (that isn't really connected).

 

[Toobuilder]

I'll get a picture of the NAV page soon.  And no, GPS2 doesn't "work". I do have a Garmin 296 attached to a serial port on the 650, but they don't seem to talk to each other.  Perhaps the HS34 detected this path and has assigned the GPS2 slot?  I didn't do it on purpose. I'm hoping I can tie the 296 to the HS34 through the serial port and assign it the "GPS2", however. I want to figure out the NAV issue first.

 

[Dynon]

The HS34 doesn't do any auto-detecting or assigning of ports, so either one of the HS34 ports or the D10A's serial port are assigned to GPS. You definitely can tie the 296 to the HS34 through the serial port, but as you say, solve one thing at a time.

More info:

I rang out the wires and am 100% sure they are correct and at least the pins are talking to each other.

When NAV is selected on the HS34 (NAVSRC), the green LED is dark. When GPS is selected, the magenta LED is lit.

On the boot up page of the 650, the heading readout matches the OBS on the HSI. I can spin the OBS and the 650 follows perfectly. The 650 and Dynon equipment are certainly talking.

 

[Toobuilder]

Here's it is with a VOR tuned and a GPS flight plan active.

Also, the green NAV LED on the HS34 is lit this time. I'm guessing this comes and goes depending on whether I have a VOR tuned or not?

Still no indication of VOR on the HSI. I should automatically see a bearing pointer for a VOR if one is selected (primary or secondary), correct?

 

[Dynon]

So that's what we'd expect to see if there's nothing coming in from the GTN (miswiring), or if the settings aren't quite configured right, or if the VOR isn't being received. You can't directly see whether or not VOR is being received on the GTN, I don't believe, and I'm not sure if the fact that you can see the ident in the frequency window means that it's actually decoding the audio morse (that would indicate that you have signal reception) or if it's reverse looked up from the database.

Can you send pictures of all of your EFIS setup pages to support at dynonavionics dot com, as well as all of the GTN's ARINC setup pages? Include a link to this thread.

 

[Toobuilder]

Will send the info, but the GTN behaves as if the ID (in the window) only shows if it's getting a good signal. In other words, it's not going immediately to a lookup table. This is further reinforced by my ability to hear the morse code in NAV audio. If I can hear it, the ID tag illuminates, if I can't, it won't.
