GNS 480 comm wiring, if any can help...

[rlallen1]

Hello... Looks like I will be installing a GNS 480 in my panel. I haven't had much luck having the wiring bundles made for me, so it looks like I will do it myself.

Really, I don't think it will be too difficult. It will be communicating with my Skyview ARINC, so I have those diagrams (easy enough).

I am needing help/assistance on the COMM part.

I currently have a MGL V6 which has be working great as my only COMM and Intercom. I had planned on removing the V6 and using the GNS 480 comm and buying a Skyview intercom.

Do I need to use any different kind of wire for the comm and intercomm? Does it need to be shielded?

I guess I am a little leary of wiring the comm up and don't want to introduce noise.

Also, would it be possible for me to keep the V6 comm/intercom and use the gns 480 as a 2nd comm (and not need to buy an intercom)? Would that require me buying an audio panel?

Thanks in advance

There are a lot of variables in your questions, and audio wiring is tricky enough that you might want to reconsider having the harnesses made professionally when you decide exactly what you want to do. Our customers have recommended SteinAir and Aerotronics for custom harnesses.

We're in the process of revising the guidance for the SV-INTERCOM-2S that using it with two COM radios is not recommended. If you do keep the V6, you WILL want to have an audio panel installed (other than the SV-INTERCOM-2S) to properly interface (and switch between) the two COM radios.

If you decide not to keep the V6, and just use the 480 COM radio, the SV-INTERCOM-2S should be suitable. See the SV-INTERCOM-2S Installation and Pilot's User Guide for wiring details.

Yes, you'll want to use shielded cable for the audio signals between COM radios, audio panels, and headsets.
