I've never seen a three ring 3.5mm connector other than on the URC RS232 cables. Any chance I could find a connector like this or it easiest to just cut the end off a URC cable?
Cutting off a URC cable would probably be the easiest - maybe not the cheapest. I bought a pack of T,R,R,S connectors off eBay a while ago. You would have to solder your connections.
I don't remember what I searched for but they didn't cost much.
