Claude, perhaps another option is available... Can the VPX be controlled with discrete switches as well? ie. could you build a switch panel that had cheap low-voltage switches, that triggered the ECB's in the VPX?
If so, and this would depend on your cockpit configuration of course, maybe you could build a simple switch panel that mounts to the bottom of your instrument panel, with a row of simple switches. That panel would connect with a harness back to your VPX. Then when Dynon adds support for the VPX to the HDX, you could remove the switch panel and reconnect the VPX to the HDX. The rest of your electrical system could then stay untouched downstream of the VPX. |
VP-X not YET supported on Dynon Skyview HDX
I have the Dynon Skyview Touch 10" display and the VP-X in my 7A. The combination has worked well and I routinely review the status of all of the circuits on the Dynon display during run-up and in flight. Because this functionality is currently unavailable in the new HDX system I would not upgrade my screens.

Can you point out where on the website this is so we can fix it? When the 10" SkyView came out in 2009, it was $3,510 for the screen and $500 for a mapping license (one per airplane). This is still listed as $3,510 on our website everywhere I can find it (SkyView Classic). |
I think I've come up with another option. I have a background in software development and a while back I built my own backup EFIS complete with GADAHRS using an Arduino for sensors and a Raspberry Pi 3 with a 7" touch screen as the front end. I wrote the user interface in Python and it all tested out great on the bench. However, I elected to not implement it and went with an AVMAP Ultra as my backup EFIS. So, here's the idea. The VP-X developer interface is documented and the SkyView serial output formats are documented. I could develop something on the Pi/Arduino that would give me full control of the VP-X, passing the required data from the SkyView (IAS, GS and RPM) back up to the VP-X. Just a matter of finding space in my panel for the screen. Just spitballing at this point but if I can get this to work, then I can keep all of my toys. Would give me something to do on the cold days this winter when I don't want to work in the garage.

Dynons comments are reveling.
""Right now we expect to put the VP-X on the HDX, but we don't have a timeframe we'd promise. We have a lot of things we want to keep adding to our systems so we're prioritizing VP-X along with everything else. Knowing customer demand sure helps."" I was told at OSH this year all their Skyview screens were interchangeable - I could run a Classic in the same panel as the HDX. Now I can't. They obviously have two versions of V15 software, one for the classic providing VPX compatibility and one for HDX without. The VPX is indispensable for me and others which makes the G3X a good upgrade option. Customer demand is the only incentive for Dynon to provide compatibility. It's actually cost them resources to remove the VPX capability. |
Quote:
And yes, there are two different version 15's, one for HDX and one for SkyView Classic. As a comparison, when G3X developed a Touch version, not only were the screens not cross-compatible, but neither were the cutouts. I can't speak to the wiring, but the HDX is a complete drop-in replacement with only the need to add 2 screw holes to the panel, which takes <5 minutes. |

Dynon said they will have compatibility in a future upgrade. Quote:

I can promise you the only reason VP-X is not in the HDX is the work it would take to put in HDX. HDX uses a completely different user interface that we need to re-write for VP-X. We sure didn't do work just to leave it out. |
Quote:
If you don't have a Dynon, how would the VPX indicate faults? Does it have an a single alarm light, or do you wire status lights alongside each switch? Maybe the solution is as simple as putting a temporary warning light in while Dynon implements an interface. |
The VP-X needs an EFIS to display faults and statuses. It replaces circuit breakers. Each switched circuit should have a signal from a physical switch (grounding a low current line). My understanding is that you can reset circuits and operate virtual switches for each circuit through the EFIS. There are a few other settings that can be touched, but all configuration is done through the Ethernet cable based configuration PC software. It doesn't seem to an overly complicated interface on the EFIS.

VP-X is a paradigm shift -
Quote:
To call VP-X a substitution for a fuse block, or CB panel is to ignore the enabling technology that ECB adds. The EFIS displays the VP-X status, and informs the pilot of faults and operating conditions which a fuse panel cannot replicate. The earlier models (VP-50, -100, and -200) included a dedicated CU (Control Unit) and a bank of assignable switches. No integration with the EFIS was required. The VP-X models require the builder to construct the switches and assign them to circuit 'pins' to activate the ECB function. There is an option to enhance the switches by using illuminated switches and the ON/OFF status is then visible on the switch panel. With EFIS/VP-X integration the flap position can be displayed on a widget in the ENGINE page of the SkyView. [Think of that as WYSIWYG, added status information beyond ON/OFF.] I'll be one of the first to say that understanding the ECB world was initially NOT intuitive and I also troubled over the oversimplification that much of the literature presents. A superficial look at ECB will miss the concept that explains paradigm shift. Yes, it's experimental - all of the glass panels, and integration is experimental and it's about flying. Yes, some can and do 'buy the package' and turn it on but there is a huge experiment progressing in E-AB aviation. Many vendors are taking significant business risks and striving to converge on the future. Aviation is not just airfoils and stick & rudder. |

I'm not saying anyone should or shouldn't use a system like VP...that's entirely up to them. All I was responding to was the idea that one has to have circuit breakers on the panel. I'm certainly not a Luddite, and have an all-glass panel myself...but it's pretty easy to start making systems more and more complex and start to bump up against the possibility of what are called "normal failures". FWIW, I wonder how such a system analyzes out when looking at SPFs...does it merely move around the SPFs, or does it create additional ones? Or does it eliminate some? ETA: BTW, illuminated switches? Got 'em...on when the circuit is on, off when not. Flap position on the EFIS? Got it (well, will whenever I get around to hooking up the sensor...point is, I don't need VP-X do get this). How are switches and pins different than switches and fuses? Don't they both requires a switch? |

switching from a Dynon system to a Garmin system. In his case, he would only have to pay for the new HDX if he can wait for the VP-X support from Dynon. If he upgrades to a Garmin he will need new screens and Garmin servos for the autopilot to work along with mostly new wiring. Compare that upgrade to a simple drop in replacement for a HDX from Dynon. I am aware that Garmin is now very competitive in the experimental market. |
Waiting

I don't wan't to go to the pre-HDX systems, as one of the responses from Dynon to a user asking about the split EMS screen on a pre-HDX system indicated that they would be entering a "no new development" phase soon, if not already the case. |

Can you point to the response from Dynon that says "no new development". I find it hard to believe the legacy Skyveiw systems will have no further development. Gary |

"v15 adds a bunch of awesome features to all SkyView displays. Highway in the Sky, runway centerlines on the map, navigation to runways, aircraft maintenance tracking, and more. Non-HDX SkyView has not been discontinued, and as you can see we've continued to add features." |
Quote:
You're correct...and my apologies for being obtuse... :) |
Quote:
I recently cancelled an HDX order and went with a second SV1000T since I already had one and budget did not allow for two new screens, at the moment. I hope to be flying soon and transition training will be in a -7 with nearly the same setup. |
Quote:
But hey...to those who like it, I say go for it! I'm quite confident that Dynon will continue to upgrade/maintain the non-HDX line for a long time to come. |
So an update here on HDX VP-X support:
Although we didn't have a firm time-frame for its addition before this week, we've always expected to have VP-X support on HDX. We often plan feature order based on demand, and this thread - along with other feedback we've gotten - has helped us prioritize this. So thanks to your help, VP-X support on HDX is now on our shortlist and will be among the next round of features we add. As for exact dates - we don't have ourselves scheduled out yet, but we typically do 4-5 major software releases a year, with smaller updates and fixes as needed. So without making promises, we'd expect VP-X support to land within the next few months. |
Great news on meeting customer demand. Thanks, Dynon!
|
Kicking myself for not just skipping to the end of this thread. Thanks Dynon! Looking forward to being able to use my VPX-Pro with HDX. I've got a few months of work to do before ordering my EFIS's anyway.
|
Great news Dynon! Thanks. Didn't really want to switch to a different brand.
|
Glad to read that the fuse/ECB debate continues almost 10 years after the release of the first VP product!
But I digress... First, glad to hear Dynon is committed to HDX support in a the near future. The VP-X will operate just fine without an EFIS in the interim until the integration is supported. You won't have variable speed trim or flap overspeed protection or landing light wig wag or in-flight reset or current draw per circuit or device status, but you'll be able to turn everything on and off and the trim and flaps will operate in "dumb" mode. If there is a circuit fault, the device will simply be off, like blowing a fuse behind the panel. When you get back on the ground, plug in your PC and reset the fault. You could even fly with a laptop in the right seat if you wanted real time information and control. Not perfect but good enough for a short while, IMO. |
Good on ya, Dynon!:cool:

Classic to HDX upgrade scenario?
So if you have an existing VPX license for a Skyview Classic EFIS display, then decide to upgrade to a Skyview HDX EFIS, will a new license need to be purchased, or can the previous license be carried over to the HDX?
