Dynon ADS-B for Skyview

[preid]

Starting a dedicated topic for this hot addition:

Another ADSB receiver announced today...I'll copy part of Dynon's release below:

...This remotely mounted receiver module integrates with the SkyView system to provide easy access to weather and traffic information on top of the detailed navigational information SkyView already provides.

At an MSRP of $995, the SV-ADSB-470 is the most affordable permanently mounted ADS-B solution on the market and has been designed specifically for experimental and light sport aircraft. It is powered directly from aircraft power and utilizes an externally mounted antenna for superior performance.

Weather is displayed graphically and textually on SkyView, and includes NEXRAD radar, METARs, and TAFS. Airport weather data can be chosen based on nearest or by airport identifier.

By combining the SV-ADSB-470 with Dynon’s existing SV-XPNDR-261 Mode-S transponder module with ADS-B out, reliable, accurate traffic will be provided to the SkyView system, even without a certified GPS on board. The ADS-B system requires the aircraft to be ADS-B OUT equipped before traffic information is provided, and Dynon’s Transponder is fully DO-260B / ADS-B out certified so SkyView owners will receive a complete traffic picture any time ADS-B services are available. Nearby traffic that is a threat will generate an audio alert so that the pilot does not need to keep looking at the screen to be alerted to nearby aircraft...

It uses serial, not the SkyView network. It also requires aircraft power and ground.

The antenna is basically another transponder antenna.

Now if I could find a serial connection!! Can I assume that I would be able to use a RX connection if the TX for that serial port is already used for another device? specifically, I believe that I can have a separate device attached to RX as long as it is the same Baud rate as the TX. Is that right?
Also if one does not have the SV-XPNDR, does that mean there is no traffic? or ADS-B OUT capability? if so any chance there may be a future version that is a transceiver, without the SV-XPNDR?
Thx

This device will use both the RX and TX port on serial, and operates at a speed that is faster than anything else we support, so it will need its own port.

Correct that we will not show traffic without our transponder. Without ADS-B out, traffic is unreliable, so we have decided not to offer this as an option.

We have no plans for an ADS-B OUT UAT device, which would need to be fully certified. We already sell a certified Mode-S transponder for $2200 which complies. It would be much cheaper to sell your current transponder and equip with our Mode-S then it ever would be to buy a totally new, Certified, ADS-B UAT.

Also, ADS-B UAT's by regulation must interface with your transponder to coordinate on the squawk code, so you can only use the newer digital transponders if you want to go the UAT route, so many people would need to upgrade transponders to use a ADS-B OUT UAT anyway.

Is this a GDL-90 format device?

If so, can Skyview use my Skyradar ADS-B receiver?

 

[dynonsupport]

It is not GDL-90, but the SkyRadar box isn't GDL-90 either and it doesn't have a serial output.

 

[thibault]

This is from the Radenna website (SkyRadar):
"SkyRadar outputs data in industry standard GDL-90 format."

My SkyRadar has a USB port for connection to a tablet computer. A USB to RS-232 cable will work fine to put out serial.

So, will Skyview support SkyRadar input data now or maybe later.

 

[dynonsupport]

You cannot connect a USB client (the radenna box) to another client (USB to RS-232 converter cable). You would need a PC in the middle with two host ports and software on the PC. USB to RS-232 is not a trivial process.

At this point, we have no plans to support any non-Dynon ADS-B receivers.

This is great, but what serial port do I use? They are already all fully assigned. But I do have 4 un used USB ports. I think the issue of the limited number of serial ports needs to be addressed. It is very easy to design a system that using Dynon modules that exceeds the available number of serial ports. Still good to see a Dynon fully integrated ADS-B solution.

Completely agree! I expect Dynon will have more great additions and it will require a Serial port. I simply have 1 RX port available, therefore limiting me from being able to expand to anything, now and in the future. Having a way to use unused connectors from the DB37 as AUX serial connections or the USB port, which are free, would be a great way to allow for future expansion for third party connections, using the Skynet network would be a great way to integrate Dynon products.

For those of you with your serial ports used up, go ahead and post what you have connected and let's see what we can figure out. Using up 5 ports is pretty rare, and we probably have some options.

GPS1
GPS2
Transponder
WX/Traffic
???

 

[preid]

RX1- SL40
TX1 SL 40
RX2 GTX 327
TX2 GTX 327 (ALT)
RX3 OPEN
TX3 VP 200 (NMEA 9800)
RX4 OPEN
TX4 VP 200 Engine Data
RX/TX 5 - SV-GPS-250

 

[dynonsupport]

The Vertical Power guys have you using TWO TX ports to talk to the VP-200? I'd ask them to update their firmware so they can read NMEA at 38,400 baud and then you can just steal the data direct from our GPS puck. Or you could get a $20 GPS to send GPS data to them.

What speed is the data to the VP-200 on the engine side? If it's 38,400, you can hook your GPS up to this RX port and leave the TX port from the SkyView to the GPS disconnected. We don't actually use that for anything at this point.

Finally, we don't send anything to/from the SL-40 today, so you're not really using that port.

What are you using the Serial to the SL40 for?  I have an SL40, but since it's comm only (no NAV function), I didn't hook these up.  Am I missing something?

ETA: Just saw support's response two messages up...

 

[airguy]

Do the serial wires need to be twisted pair?

 

[dynonsupport]

No, they don't need to be twisted.

Thank you for the response. I was actually part of the VP beta and I know that it's NMEA basic 9600 for GPS, and 57600 for EMS and ADHARS info. I did try to get the speeds to be more aligned with the GPS speed from the -250 but it ended with these settings.
I have the SL40 setup awaiting the update I thought I heard a year back that would send the frequency info over (once Dynon got their COM radio released) That may be my only option, if I decide to add anything.
Would still be nice to have another serial port however, if it wouldn't be a big programming deal- or is there a limitation on 5?

 

[dynonsupport]

Serial ports are hardware. We can't just add them in software, and we already have more usable ports than any EFIS out there.

We do have options to add more with external hardware, but this is not a trivial task, and not one we can take up unless we do find that lots of our customers are short on serial ports. The use of the VP-200 taking up two serial ports is really rare so we just don't see a lot of customers having an issue. Even with radios and the VP-X, we can normally handle it:

GPS
Transponder
WX / Traffic
VP-X
COM/NAV radio (SL-30)

As an FYI, our radio will not be a serial device so it won't take up a port. The ADS-B box transmits so much data that we couldn't put it on the SkyView Network, which is why it's serial.

 

[jbeaver]

When we will be able to place an order for the SV-ADSB-470?

 

[dynonsupport]

When we will be able to place an order for the SV-ADSB-470?

Not until it's shipping, which is "Fall, 2012".

 

[vlittle]

#1 - SV-XPNDR-261
#2 - SV-XPNDR-261 GPS position (output only) and panel port
#3 - Garmin SL30 Nav In and Comm Out (waiting for Dynon to Support)
#4 - Garmin Aera 500 (input only) as alternate GPS device
#5 - SV-GPS-250

It's possible to recover port #2 and repurpose for ADS-B if GPS data from a SV-GPS-250 or the Garmin Aera can be used by the transponder.

This is a single SkyView system until Dynon releases a 3" SV network compatible EFIS.
