Dynon AP controlled by Ipad with Skydemon

Excellent point, well made. It would be very nice if those RS232 inputs were as you've shown. Maybe they were not on the diagram I pasted because they are just not used in a normal radio set up. I agree that Pin 5 and a ground may well allow the Bluetooth dongle to do its job. Only one real way to find out

Looking at the HDX wiring diagram documentation, it shows pins 5&6 being used as data Tx & Rx from the SVCom Panel. It’s possible that the com panel is basically the same as the TC90, just packaged differently.

It goes beyond the simple physical connection. The structure of the data itself may not be compatible. But I like where you're going with this.

Because of Dynon's refusal to incorporate an integrated intercom into their radio, I am fortunate in having the TC90 controller and a TY91 radio, linked to my HDX. I will eventually get round to installing the BT dongle for the autopilot and, maybe, the radio. I often use the radio transfer facility from my HDX, so I'm not really sure what difference doing it from SkyDemon would make.

On the other hand I may just do it because I like gadgets

Most aircraft radios do not have intercoms incorporated. Dynon's lack of doing so is hardly notable.

Totally agree re data structure.

On reviewing the Dynon installation manual for 3rd party devices it looks like the HDX screen RS232 interface uses standard NMEA 0183 protocols that match the output from SkyDemon so it should work with no issue. If you're using the BLE module to connect to the AP as well you would need to reconfigure the baud rate to 9600 as per the TY91 installation documentation below.

It looks like everything aligns... and if the weather wasn't so dire here I'd go to the airfield and investigate.

Although the screen below relates to the Autopilot messages transmitted from SD it matches the standard NMEA sentences that the HDX uses.

For me, the lack of a 'memory' function to store frequently used frequencies within the HDX is a little limiting so having the ability to touch the relevant frequency in SD and dialling the HDX up would be useful. I believe the TC90 can store 100 frequencies so may not be so useful in your setting.

However, like you I also like the 'gadget' part of this and would like to get it working. I'm so impressed with the SD/AP link, it's very convenient and I think will be too.

What vertical nav data will be sent from SlyDemon? There’s no approach information as it’s a navigation app, not an FMC.

I was thinking that SD could send height information much like the heading information along the route with a view that the data could initiate a climb of descent however I hadn't really given much thought on how (or if) it could work to be honest.

Been a while since any updates on this thread. Has anybody managed to to upload frequency from Skydemon to Skyview as well as drive autopilot yet?

 

[skyboy999]

Update:
I wrote to Trig to enquire and the bottom line is that it is not presently possible to do the frequency upload as the RS232 connection (available for use with the Trig TC90 head unit) is used by Skyview. However, they noted that I was not the first to ask about this and they will raise with Dynon.

I presume you have SV servos so SV is driving the autopilot with Skydemon as a Nav source to SV. Is this correct and can the BT adapter just use one of the harness serial connections ie no need for an ARINC?

I’m setting currently setting up the Bluetooth to run the AP from SkyDemon
Any chance you could share the port setup configuration for the Dynon please to run the AP. I’m all sorted on the SkyDemon side of it but can’t find any info on the Dynon port setting
Any help appreciated

OK. Yours might be slightly different as will depend on what you already have configured…
SERIAL IN DEVICE: Garmin 296. (Others will probably work also but someone on post said that is what they used so I did likewise)
SERIAL IN FUNCTION: GPS2 (as I already had another GPS connected. If you do not, then use GPS1)
NAVIGATION SOURCE DISPLAY NAME: SKYDEMN
SERIAL IN/OUT BAUD RATE: 9600
SERIAL OUT DEVICE: NONE

As slight aside, I had some setup problems with my BT adapter (Irxon BT578) in relation to power which took a little while to track down and resolve. No need to go into detail but, suffice to say, if things do not work properly check with an alternate power source.

Hi
Thanks for the info
I’ll give it a try when next at the airfield
