Unfortunately, Yaesu has had at least two pin-out's for its 8 pin connectors. I use Heil mics and when I tried to use my Heil AD-1-Y (yellow) adapter from my Yaesu FT-736R on the Flex 5000A it did not work.
The pin-out's are: FT-736R adapter Pin Flex 5000A Audio input + 1 no connection PTT + 2 +5 VDC 65ma no connection 3 no connection no connection 4 no connection 8 VDC 10ma 5 ground no connection 6 PTT + Audio ground 7 Audio ground PTT ground 8 Audio input + I rewired the Heil adapter to match the Flex and all worked fine. The FT-736R went out of production in 1995 so the pin-out must have been revised on models after this date. 73, John, N8WNA -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ray, K9DUR Sent: Saturday, July 07, 2012 7:47 PM To: 'Robert Costa, KB6QXM'; 'John Molenda'; 'flex-radio reflector' Subject: Re: [FlexEdge] flex 1500 Robert, Yep -- Yaesu pin-out. Only difference is that the FLEX-5000 uses an 8-pin Foster connector instead of the RJ-45 modular connector. 73, Ray, K9DUR http://k9dur.info _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
