Hi Greg, The adapter you're hoping to find would need to have a USB *jack*, talk to a USB serial device (the KXUSB-A) you've plugged in, convert that serial data *back* to RS232, and wire it to an audio jack or plug with the correct pinout for your rig interface.
What you'll *find* if you look for USB to stereo adapters would have a USB *plug* (or device-side jack), present as an *audio* device to a USB host (computer), convert digital audio to analog, and wire it to an audio jack for headphones or speakers. Unfortunately this won't work at all -- they've got totally different genders of connector, directions of data flow, and types of signals, and data flow. I'd suggest taking USB out of the picture entirely, and keeping it as RS232: Grab a regular DB9-DB9 serial cable, from Elecraft if they use a nonstandard pinout, or from anywhere if they use a standard one. Grab DB9 and 3.5mm audio connectors of the right sex to plug into your serial cable and your rig interface. Find some wire of a sturdy gauge, check the pinout for your rig interface, and solder yourself an adapter. I don't have any *good* advice on holding it together, but my instinct would be either heat shrink around the whole thing or a tiny project box with the DB9 and an audio jack (instead of the plug) mounted. You might also be able to use Elecraft's RS232 to 3.5mm cable, but you'd need to check the pinout against your rig interface -- as far as I know there's no standard for routing RS232 through an audio jack. Hope this helps, Julie ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
