The schematic diagram (on the Elecraft web site) shows the KIO3's serial connector pin 7 is RTS_IN.
According to the schematic, pin 2 is RxD out, pin 3 is TxD in, pin 4 is DTR in, pin 5 is "common" (connected through a small choke to ground), pin 7 is RTS in, and the remaining DE9 pins are not connected. The schematics are available from the Elecraft manual download page, http://www.elecraft.com/K2_Manual_Download_Page.htm.

Is it used or unused? It is not mentioned in my manual, neither in the unused pins (1, 8, 9) nor in the list of used pins. 73! de Werner OE9FWV -- View this message in context: http://n2.nabble.com/KIO3-Pinout-tp3851431p3859578.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ 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 ______________________________________________________________ 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
