Re: Remote ON control of K3 - How W5AJ implemented
toggle quoted messageShow quoted text
I use the ethernet -> 8 relay module http://vkmodule.com.ua/Ethernet/Socket4.html
Made in Ukraine. Costs less then $40.
It is switching on/off everything at the remote site: K3, linears HF and 50 MHz, antenna relay unit and rotator controllers.
I'm sure there is a lot of this stuff made in BY

One of the challenges I’ve had with operating remote was leaving the K3 on when departing
this could be for the office, To visit grandkids, campout using phone as hotspot, etc.
No method to remotely turn on the K3….
The K3 can be easily turned on Remote via Pin 8 on ACC port
but how to pull it low?
My hardware was ready for three devices, USB to RS232 adaptor, W3YY interface board to get the optical isolators
Software to fire each of the three control lines on RS232 port was missing….
Wayne, W5XD wrote program that I could use and placed it in public domain
that was final missing piece.
Recently tested and turned the Elecraft K3 on from PC!! works
This would work for any device requiring a pin be pulled low to activate
setup a web page with “How I did it”, includes pictures which don’t always post on reflectors
