You have the DTR and RTL on the serial connector. If you are not using them for something else, like keying you could use one of them to control a relay to toggle the pin on the accessory connector. Willis 'Cookie' Cooke K5EWJ

You should use an external device (a relay or logic) to pull a pin low on the K3 back panel 15-pin accessory connector that will turn power on. See the K3 Owner's reference (Revision D6), page 18 for the pinout of the ACC (accessory I/O connector), especially pin 8, and the description on page 44, "Remote Control of the K3", "Remote Power On/Off". Your external control device needs to ground the Accessory I/O pin 8, "POWER ON". 73 de Dick, K6KR >I would like to run my K3 remotely and was wondering how can I switch it >on remotely, is there a way of doing this, perhaps by sending a sequence >of bytes on the serial port? >Regards, >Berni >G0IDA ______________________________________________________________ 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
