Followup on the iPhone as a wired remote control for K2: Thanks to the redpark.com cable, it's working - got a prototype iPhone app doing reads/writes directly with no need for Wi-Fi, Bluetooth or other devices inbetween (well there is an embedded controller inside the cable, but the cable still just looks like a cable).
Since the K2's AUX I/O pinout isn't the same as the RS-232 standard (NEVER attach a 'full' RS-232 cable directly to the K2!) a second cable is needed between the K2 and the redpark cable. In my case I simply wired pin 2 to 2, pin 3 to 3, pin 5 to 5 (signal ground). Also, on the K2 end only, attached the bare wire to pin 1 (chassis ground), and on the end that mates to the redpark cable, wired pin 7 to 8 (RTS/CTS loopback, see p. 13 of Elecraft KIO2 manual, Rev. C). I'm using redpark's C2-DB9V. 73, --Andrew, NV1B .. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
