Installing a GPS 175 with a Dynon D100

[TheNewGuy]

Howdy all. I was able to track down a HS34 for my set up and it seems all that's left is the Garmin GPS 175 and Garmin ARINC 429. However, I do need connectors for the male and female ports on the back of the HS34. All I have is the Bracket and Module itself.

Moving forward, do I need a Male and Female D-SUB 25-PIN connector to use for the wiring harness? Not 100% sure which connector I will need. Does anyone happen to know?

You can find the HS34 wiring schematics and DB25 pinout definitions in the appendix of the latest D100 installation manual.

You will definitely be connecting to the HS34 male DSUB connector. Connecting to the female HS34 connector will be a maybe, depending on what devices you plan on using.

I appreciate it and thanks for pointing me in the right direction. I will be installing a GPS 175 to make her IFR

Dont know what autopilot you will be using or other systems you may have like a SL30 but these two drawings will help to get the 175 driving the D100 HSI and let you choose the input source. The aerinc429 is part of the 175 so you do not need another module.

Thank you very much. I have a Dynon system. I’ve never made a wiring harness before so I’m hoping SteinAir will be able to expedite a small job like this. I used the approach fast stack in my beech, but if I recall correctly, they require you purchase the Hub which is not necessary for my setup

If you aren’t in a hurry making wiring harnesses is an easy skill to learn. The Garmin install manual is very detailed on proper shielding and installation techniques for their wiring diagrams. D100/180 also has an easy to follow install guide. Between the two you should be able to make your own easily. Just buy some stein air tools for making the harness.

Sounds like a Major Payne but you might be right

Also, while you're at it, you should get servos so you can use the D1xx autopilot. With or without the AP74 the D1xx autopilot will be useful for IFR flying. Last two good items would be an AoA pitot and an OAT. Of all all of these, only the HS34 and AP74 will not work with a Skyview upgrade when the time time comes.

D100, HS34 and Garmin 375 (or 175) works great! ...and don't mind the airspeed miss on the backup instrument. I've got that sorted.

Similar setup to Peter with AV30 versus the G5, works well and the Aera760 is very useful as an extended display for the 175/375 series navigators.

I always thought the purpose of an HS34 was to support the native autopilot that is built into the D100, but I see from your panel photo that you also have a Bendix King / TruTrak autopilot, presumably with Bendix King / TruTrak servos.

How do the G175, HS34, TruTrak, and D100 interact with each other?

HS34 is the ARINC conversion to talk to other units if they also use ARINC. It also takes other nav inputs.

(autopilot...) That's the AP74. Same size box as the HS34.

As Major Payne noted the HS34 lets you connect multiple sources to the D100 via arinc429 and RS232. It also lets you “pass through” the 429 to an autopilot . In my case I have the 375, SL30, and aera 760 connected to the D100, and the 375 and aera 760 connected to the TT autopilot.

I want to add the GPS 175 to my RV7 panel which has a Skyview Touch and Skyview Classic along with an Apollo SL-30 NavCom. Does this mean I don't need to install the Dynon ARINC-429?

You'll still need it to get all the functionality out of the skyview and autopilot

An ARINC connection is needed on each end. The 175 has one, and some important data (like glide slope) is not sent out over RS232 connections, you must have an ARINC link. So the Skyview will need to support ARINC lines, both in and out (2 pairs). The SL30 does not use ARINC, everything is RS232, so you don't have to worry about ARINC to the SL30.

So, with 2 Skyviews (Touch & Classic) can I just use one ARINC? Or do I need one for each Skyview to communicate with the GPS 175 ? Also, the SL30 is 20+ years old and my only radio in the panel (I do have a handheld on board). Should I think about getting the more expensive GPS 355 with the comm radio? How important would that be with the reliability of the SL30?

No, just one. Splice the wires if they terminate in the same pin

Tough question. IMHO the SL30 is the finest nav-com ever made, you can simultaneously receive an ILS and a VOR cross fix. But they are getting long in the tooth, finding replacement parts is getting hard. Notice, your question only replaces the com, not the nav, so this is a bit apples-oranges. Ask: Do you fly a lot of IFR? Into Class B or C airports, where leaving no-radio might be difficult? Are you willing to not fly for a few weeks after the SL30 dies? Are you willing to fly with just GPS (and maybe IFR), no VOR/ILS? Only you can answer these questions. IF it were I, I would strongly consider buying a Trig Com radio, and keeping the SL30. This puts off any decision about ILS capability until such time as the SL30 actually dies. Who knows, it may be another 20 years. If you do not have panel space for both the Trig and the SL30, then I'd consider the 355 (and again, keep the SL30).
