Bottom line: The wires are not the current limiting factor, it's the D connector's pins. Could be conservative from a current standpoint when Dynon uses two pins for power and ground to Skyview Display but no second-guessing the Dynon install manual. Bob Nuckolls teaches us to use lengths of...

H Carlton, I can use the two harnesses, sent you a PM.

I see folks in this thread are referencing two different Garmin installation manuals... 190-02207-A1 rev2 (AML STC) and 190-02207-00 rev2 (TSO). I have both if you send me a message on this forum. A bottom line about the two power pins is that both IMs say "All power leads and ground leads are...

I'm with Bob Nuckolls re using fuses instead of breakers. I would add space for more switches and/or breakers than you think you will need but for me fuses are in Bussmann 15600 fuse panels behind the instrument panel. My setup: The AP servos get a 5A pullable breaker that feeds them both...

I imagine it's because the transponder is in what is referred to as the microwave frequency range of 300 MHz to 300 GHz and as Wikipedia says: TNC "has better performance than the BNC connector at microwave frequencies". https://en.wikipedia.org/wiki/TNC_connector BTW, these connectors were...

You don't need the Ray Allen trim indicator because Skyview shows trim position if you have the EMS module. SkyView (except the SE version) and GPS 175 have auto dimming. If auto dimming works well you don't need a separate dimmer knob. Have you tried the auto dimming feature? GPS 175 wants a...

Auto-trim is a feature that reduces pilot workload because you don't have to respond to the visual prompts on Skyview telling you to trim up or down. The AC needs to be trimmed because proper trim: Reduces the amount of torque the AP servo needs to apply. Reduces electrical power to the AP...

You have a number of items close to the ADAHRS. Dynon told me the ADAHRS should be 18" from the AP servo unless a remote compass is used.

I suppose L-Com is a good brand. You can google "ebay L-Com DGB9M DB9 D-Sub 9 pin Male to Male connector/Adapter Gender Changer" and it comes up with https://www.ebay.com/itm/363276167468 $6 for one and $9 for two.

If you google "vansaircraft op-60" you'll see the Van's mount for newer RVs where the ADAHRS is under the turtledeck in front of the first bulkhead behind the baggage bulkhead. This location appears to be rigid and keeps it away from the pitch servo and the shoulder harness cables. Keep in mind...

To avoid confusions as to what is back, front, rear, I like photos. Hope this one tells the story... a D9F on a cable with backshell in place. I assume connector manufacturers get it right in the molds and reference that. I look at the numbers rather than trying to figure out what is back...

I'm guessing I'm misinterpreting your words and images. You are attaching a D9Female to each end of the wires. Does each wire go to the same pin number as molded into each D9F? The image below has been edited to match my next post. Have you respected the twisted pairs described in the...

From the latest Skyview System Installation Guide, rev AH: "SkyView units cannot / should not be mixed For planning your SkyView system, or upgrades, Dynon Avionics recommends planning / budgeting for installing the same “family” of SkyView displays, not to “mix” displays from different...

"The network status does not show the transponder device either." The transponder is not on the network, it's on a serial port from the EFIS D37 connector (multiple screens, if any, connected it parallel). SETUP MENU > LOCAL DISPLAY SETUP > DISPLAY HARDWARE

Plane Sights Universal Pitot Cover PSUPTC0707. Shown here on Dynon heated pitot.

In case my spreadsheet is helpful. It's based on the installation manual and it has a heading "Panel Instruments". BTW, no current draw info there but have you seen Dynon schematic 103488-000. Mr Google will find it for you if you search "103488-000". It's titled "WIRING DIAGRAM TYPICAL HDX...

The SkyView Display power inputs are not diode OR'd. There are two power inputs, and also two ground connections, because the D connector pins individually are not rated for the current. This is common practice across manufacturers. Ref the SkyView System Installation Guide, "to reduce current...

Looks like the SV-COM-425 transceiver is legacy with the new transceiver being SV-COM-T25 which shares form factor with -T8. I put the -T8 STL into the folder linked from post 2.

Hi Josh, I made the STL files you asked for. Same folder as linked in post 2.
