From the owners manual (page 44 in rev D2): "Remote Power On/Off
A remote-control system can pull the POWER ON line to ground (ACC connector, pg. 18) to turn the K3 ON. To turn it OFF, the controller must send the K3 a "PS0;" remote-control command via the RS232 interface, then deactivate the POWER ON signal. This sequence ensures that nonvolatile memory is updated correctly before shut-down." Note that it doesn't say how long it takes to update the NVRAM after the above process is completed. In other words, how soon after deactivating the POWER ON signal can I shut down the 13.8V supply? 73 -- Joe KB8AP On Jun 7, 2009, at 9:10 AM, Geoffrey Mackenzie-Kennedy wrote: > > Is there any interface available on the K3 which would allow an > external > automatic protective shutdown system to meet this requirement, > rather than > having to press the POWER button by hand? ______________________________________________________________ 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
