I should have added that the alarm is also available on the PC serial interface. Interrogating the KPA500 with ^FL; will return the current fault value in the form ^FLnn; where nn is a 2 digit number indicating the current fault (00 for no fault).
It would be possible to use this fault report to vocalize the actual fault condition and play that fault message through your headphones. 73, Andy, k3wyc ________________________________ From: Andy Durbin Sent: Monday, April 8, 2019 10:40 AM To: elecraft@mailman.qth.net Subject: KPA500 alarm The alarm signal is available on AUX1 connector pin 7 and is pulled low when an alarm is active. I have it permanently connected to my data logger and have used it as a trigger for my storage 'scope. It could be used to drive an external alarm of any sort that you chose. 73, Andy k3wyc ______________________________________________________________ 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
