If I may ask the electric gurus a few questions on the Dynon SV-ARINC-429 connection to a GNS 430W. I attached a picture and drew in what I thought it should be.
1. Should the wires be shielded twisted pair?
2. Should they be grounded on both ends like in the picture in red? If so, is the ARINC side ground just attached to the airframe?
3. Is the GPS RS 232 OUT just a single non-shielded wire?
Here's what makes me think it should be shielded wiring. Although not Dynon, this page in the 400W series install manual shows ARINC connections with shielded twisted pair. All the other 400W to ARINC connections also show the same.
