SV-INTERCOM-2S connection to Garmin GTR200 com

[James_Rekieta]

I am installing a single GTR 200 com radio and chose to install the SV-INTERCOM-2S.
I am connecting the intercom pin #14 (Radio 1 Audio input) to the com pin #10 (receiver Audio out hi). I'm pretty confident on this connection but not real sure about the intercom pin #25 (radio 1 mic out) and pin #12 (Radio PTT). On the com connector there is a PILOT MIC IN (PIN 17) and a COPILOT MIC IN (PIN 16). Likewise on the PTT, there is a PILOT PTT (PIN 35) AND A COPILOT PTT (PIN15) on the com connector. There is not a "radio input pin connection" for the PTT or the mic. output from the intercom, on the com connector.
I'm GUESSING that I should connect the MIC and PTT from the intercom to the Pilot Mic IN and the Pilot PTT of the comm radio?
Need clarification.
Thanks,
Jrans

Jrans:

We cover the basics of connecting an SV-COM-C25/X83 via an SV-INTERCOM-2S in the SkyView System Installation Guide. More definitive information for connecting a non-Dynon COM radio is the SV-INTERCOM-2S is the SV-INTERCOM-2S Installation and Pilot's User Guide, specifically Page 2-4 - SV-INTERCOM-2S to Generic COM Radio Wiring Guide.

That said, I'll try to help here.

First, the main reason for installing the SV-INTERCOM-2S is so the pilot and copilot can converse easily between themselves (through the SV-INTERCOM-2S). The pilot, and optionally the copilot, can use the COM radio, and optionally a second COM radio, through the headsets that are connected directly to the SV-INTERCOM-2S.

Some COM radios have provisions for a "mini intercom" function and two headsets - you'll have to decide which unit you want to have the headsets connected to... which unit will "manage" the headsets. If, in your installation, that's the SV-INTERCOM-2S, you won't use the copilot connections on the COM radio - the SV-INTERCOM-2S will "manage" the switching of audio from the pilot and copilot headsets to and from the COM radio.

SV-INTERCOM-2S
Pin 14 - Radio 1 Audio Input will be connected to the COM's audio output (Pin 10)
Pin 25 - Aircraft Radio 1 Mic will be connected to the COM's Pilot Microphone (Pin 17)
Pin 12 - Radio PTT will be connected to the COM's Pilot PTT (Pin 35)

I am using the SV-INTERCOM-2S Installation and Users Guide to install the unit. The pinout and description of the wiring on the PTT and Mic connection to a generic com radio is not real clear to a novice like me :-[ but your description above is VERY clear Thank you very much for the description and verification.
Next beer is on me.
