That sort of confirms my instinct: to go with B&C because I've yet to hear anyone say anything negative about them! Okay, they're expensive but, at the end of the day, spending 50 now for years of reliable service, and a known track record seems to make sense.

There were a couple stand alone PTT switches with velcro attachments for the buttons that came with the intercom, but I'd rather use my in-stick switches that I'm making. It looks like I could make a Y adapter with a couple 0.210" jacks and whatever sized plug fits the radio mic jack. I haven't got the radio yet, but the Dynon manual says this jack is 3 mm and the speaker jack is 2.5 mm. It looks like I could terminate the wires from one .210" jack into the terminals of the other jack, instead of splicing them outside the unit as my drawing shows. I have some 2-conductor shielded cable. Could I use this and connect the shield to the sleeves? -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=358588#358588 Attachments: http://forums.matronics.com//files/rst_intercom_manual_5_of_5_resized_518.jpg http://forums.matronics.com//files/ptt_y_adapter_for_rst_intercom_115.jpg ________________________________ Message 4 _____________________________________ Time: 10:27:07 AM PST US From: "Robert L.

Could I use this and connect >the shield to the sleeves? You only need two conductors total . . . a ptt and ground lead. Shielding is not necessary but shielded wires can offer some conveniences. My low ohms adapters Emacs! Use shielded wire for convenience of assembly and nice 'round' lead wires as opposed to the spiral lumpiness of a twisted pair. You can parallel as many PTT buttons as you wish. You will find that the ground side of the PTT line shares a ground side of the mic audio both tied to the shell of the plug or jack.

The only things of use are: Power to the 296: Red: +12v Black: Ground Feed to autopilot: Blue: serial data out (NMEA) Voice alert (Terrain/Obstacle): Brown: feed to audio panel If this is your interface to your aircraft systems...no standard DB-9 pinout is required. Put those leads in any hole you want. If you want to be direct plug compatible with =9Cdevice X=9D, then you should use =9Cdevice X=9D pinouts. -James From: Ralph Finch Sent: Sunday, November 20, 2011 12:28 PM Subject: AeroElectric-List: pinout for garmin 9-pin cable to DSUB I have a cable which connects a 9-pin DIN Garmin GPS (296 in my case) to anything else...the cable has bare wire ends.

The port that comes from you computer is a male port, and the port that comes from your GPS would be a male port as well, if I follow you. Typically a female-female serial cable is a crossover-type cable with pins 2 and 3 "crossed-over". You'd need to verify that with a meter, but that would swap your pins 2 and 3 in the GPS connector. In general, for DB9 serial: DTE has a male connector (computers, old green-screen dumb terminals) DCE has a female connector (modems) This is not always followed though, so it's best to check cables with a meter and consult the manual for nonstandard pinouts.

It was tough going because the switches were in the panel and wired up to the wig-wag flasher. There was not a lot of room. I had found a sketch I had made with the pin assignments wrong on it but could not figure out the source of that diagram. All in all I was just trying to get one more piece of information to trouble shoot a problem. The wrong pin assignments in my sketch had me wiring things wrong. They are corrected now and everything works as designed/desired. -------- John Keller, TX RV-8 N247TD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=358610#358610 ________________________________ Message 11 ____________________________________ Time: 05:50:03 PM PST US Subject: AeroElectric-List: Re: PTT Y adapter for RST intercom From: "messydeer" Yes, two conductors only.

Do you mean headphone wiring? I left out the headphone wiring, cuz I'd plug my headset mic and phone plugs into the RST intercom box. According to the RST diagram, the lead from this box labeled 'ics phones' would get plugged into the handheld headphone jack. What I'm trying to replace is the PTT wiring, labeled 'B' in this diagram, so I intended to depict the two PTT switches, the two mic jacks, and the single mic plug. I erased the ring connections in my drawing, leaving just the shell and tip connects for the plugs. > Keep in mind that PTT goes > to the tip connector of the conventional, .205" microphone > plug. I also noticed in the micjack.html article the mic jacks have ring terminals that are connected to the pilot and copilot mic hi leads of the 760 radio, while in another drawing of yours, http://www.aeroelectric.com/PPS/Audio/hv1_760vhf.pdf you show these mic jacks with nothing connected to them. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=358618#358618 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
