Your docs state that the dimmer output (currently unsupported) is an open collector pwm output. 1) Is this a pnp or npn output (i.e. does it pull to +12 or ground or)? 2) Can it drive any appreciable current, or is it intended to be just a drive signal to an external device? The only device...

Re: Software pricing: per screen or per SV network Thanks, that's the right answer, you guys have thought this through. V

Are the factory wiring harness SVN, RS232 and audio cables shielded, twisted or otherwise? I'm planning connectors and I need to know if I need to accommodate shield carry-throughs. If there is a mix, it would be nice to know which ones are which. Thanks, Vern

The dual SV power inputs, are they diode isolated? I'd like to wire redundant power connections from separate circuit breakers, but this only works if the SV power inputs are diode isolated (i.e. a fault on one bus does not propagate to the other bus). Thanks, Vern

When Dynon offers the software add-ons for terrain, SynVis and so on, is the pricing good for the entire network (multiple screens) or per EFIS unit? This could be quite a cost penalty for multi-EFIS installations if we have to pay multiple times for the same database. Vern

Good! I assume that you will use the Navworx MFD serial links. That's what I'll assume for my schematics. I hope Dynon works closely with Navworx. It would be nice to see tighter integration. For example the Navworx devices have a maintenance port that can be driven by a SV if enough serial...

The big picture, however, is that a UAT (Universal Access Transceiver) will provide ADS-B out, in-cockpit TIS-B traffic and FIS-B weather. Garmin (and Dynon) transponders do not provide all of this capability.  While meeting the requirement for ADS-B out, the provided TIS capability (not the...

I see Dynon has announced that multiple EFIS systems can or-tie their serial outputs to drive other instruments. This allows for graceful failure scenarios without an external switch. This is a great innovation because it simplifies wiring and dramatically improves fault tolerance of multiple...

Two answers to this: 1) In formation flight, many operations are done by feel because switch positions are memorized.  The ability to use switches with their tactile feedback is superior to a menu-driven controller. 2)The probability of failure depends on the architecture.  With discrete...

Re: Adding secondary screen option for tandem airc As much as it pains me to say so on a Dynon forum, The Trutrak Gemini devices seem to fit the bill for affordable backseat and/or backup EFIS systems. I have been suggesting on this forum for quite a whioe that Dynon make low-profile versions...

In my opinion, an aircraft should inform the pilot who then makes all of the configuration decisions. Automatic decisions by a piece of hardware/software often have unintended consequences. For example, an "Airborne" function that configures the transponder sounds fine until you are flying...

I would like to use voltmeter 2 to measure the advance on my electronic ignition, which has a full-scale output of 200 mV. What is the resolution of the SkyView voltmeter, and can it support this application? Thanks, Vern Little

With all due respect, this is a significant flaw in the Skyview architecture. The location requirements for the magnetometer which wants to be in the wing or tail are not compatible with the pitot/static/aoa/attitude systems, which want to be behind the panel. In my HR-II, I am having real...

What is the input resistance of the voltmeter input pins? I'd like to permanently connect on input directly to the battery (unswitched), but I don't want it to discharge over time if there is too much leakage. Vern

I may have suggested this before, but here is a function that can be implemented with the Skyview system: Flap overspeed alarm. Tie a flap position switch (or potentiometer) to an input (contact or gp input) to raise an alarm is Vfe is exceed while the flaps are deployed. This would eliminate...

The Skyview systems support stereo output.  I assume that this will be the primary output associated with warnings and alarms, plus future enhancements (playing MP3 files perhaps?). What is the recommended intercom/audio panel wiring:   an unswitched stereo input; a switched (automuted) stereo...

Great, that solves the problem nicely, plus some various sense lines I need. V

That's what I was concerned with. 3-axis trim plus flap position is 4 inputs. As I understand it, your EMS only supports a total of 3 inputs. Vern

Will the Skyview EMS support 3-axis trim indication? Most engine monitors show flaps, pitch and roll trim, but not yaw trim. Thanks, Vern

Saw your announcement on the web site that mentioned a video input at some point. This is great! Taildraggers can plan for a taxi-aid camera system for ground ops. Also can be used to check six in formation (with the appropriate mirror-imaging). Thanks, Vern
