    From: James Kilford <james@etravel.org>
    Ralph, Could you find a suitable automotive version, and simply take it out of the cigar lighter package and hard wire into the plane? I think that's what I would do. It gives you a chance to try all sorts of low-cost items and then pick a couple of the right ones. For the presentation at the instrument panel, I would go for a USB extension cable for ease of mounting. This can then plug into your power supply. FWIW.

The greatest risk for most options are (1) expenditure of $time$ to integrate the device into the airplane (2) performance to requirements and (3) radiated and conducted EMC. The technology is mature . . . 2 and 3 are relatively low value risks. But one can spend a lot of hammer-n-tongs effort making a 'clean' and robust installation. Condider products tailored to the task like these http://tinyurl.com/m8kfz6h http://tinyurl.com/qhdwgdl This would be a good value at 3x the price due to it's ease of installation. No sheet metal work what so ever except to cut usb connector clearance holes. Bob . . .

Your post gave me the hint I needed to sleuth out the rest of the story. The standard card edge connector on my radio is different from the schematic and board diagrams in the service manual that I have (with Feb 2008 addendum). The data sheet for the ADM202 does indeed show continuous short circuit as an absolute maximum condition but it also says "Exposure to absolute maximum rating conditions for extended periods may affect device reliability." The icom manual shows a 1K resistor in series with the rs232 line out if you fit the optional Dsub back panel to the radio. It shows no connection to pin 2 for the standard card edge back panel but it does show a 100R resistor to the separate data out jack. I was able to confirm that my radio in fact has a 1K resistor in series with pin 2. So I can interchange the A200 and A210 without modifying the aircraft tray and without any worries since I'm not using the intercom function. thanks again Ken

    One of the OSH aviation vendors had a two usb port black plastic jack that looked like a drop in replacement for a cigarette lighter panel hole. I don't have any other details other than it had a flip up plastic cover and I believe it was intended to be wired directly to 12 volt power. Ken On 04/08/2014 10:32 AM, Robert L.

I ended up hacking the end of the iPad's USB cable to add the resistors (actually I added a micro-sized potentiometer adjusted to the proper resistance), which is now dedicated to the airplane, and it charges the ipad just fine. Not difficult, but not as "clean" an installation as I had originally envisioned. -Dj -- Dj Merrill - N1JOV - VP EAA Chapter 87 Sportsman 2+2 Builder #7118 N421DJ - http://deej.net/sportsman/ Glastar Flyer N866RH - http://deej.net/glastar/

Yes, but reliability only for that function which takes a specialized GPS based mapping/data base product . . . does anyone offer such a thing? Not sure I'd want any 'automatic' gizmo twisting my radio knobs anyhow. >The icom manual shows a 1K resistor in series with the rs232 line >out if you fit the optional Dsub back panel to the radio.

Didn't see how the intercom function came into consideration . . . are those two pins not limited to panel lighting in the A200? Bob . . .

There is actually a warning on the icom site about changes in the intercom and GPS connections on the A210. The vendor and icom both mentioned intercom connection changes. I just didn't want steer anyone wrong with my conclusion since some folks probably are using the intercom function. Ken
