GPS175 install questions
Tonight I'm reading through a GPS175 install manual to wrap my head around the wiring requirements, which means...questions. Oh yes indeed.
Brief overview of my intended installation: EFIS will be a dual Skyview HDX system with the ARINC-429 interface box. The GPS will also be providing serial data to the Skyview transponder and an Artex ELT. No other Garmin stuff installed anywhere.
First, regarding the pinouts: it would appear that out of this monster 62-pin connector, I really only need a small handful of connections:
Second, and sort of springing off #1, there are four pins for a "config module." Is this something required for all installations? Is this module included with the unit? As in, do I even have to care about this?
Appreciate any info.
The config module is included with the GPS 175. It will be physically located in a special holder that is part of the metal backshell assembly of the large connector for the GPS unit. This module will contain all the uniqueness of the installation that you will program into the module at power- on time.
The Dynon ADHARS module provides altitude info to the Dynon transponder. I believe the Dynon install manule shows an example of the wiring for a Garmin GPS navigator using the a serial line and the -429 interface module.
Thanks for the info.
To clarify a bit, the GPS175 will be providing certified GPS data to the transponder for ADS-B Out compliance. This is mainly because I picked up an older SV-250 GPS puck for dirt cheap. Gotta save $$$ somewhere on this build...anyway, that's the reason for having a serial connection to the transponder.
Send me an email to firstname.lastname@example.org, and I will send you a document that I made up with the complete wiring you need with pictures of the SkyView and Dynon configuration setups.
