Automatic Echo-link System
Automatic Echo-Link System
From this section I ma going to introduce you something about the auto power controlling system for your Echo-Link, I think this is not necessary if your whole system running with the solar power or wind power source. But unfortunately on my Echo-Link system I use solar power and main power (100V) source switching system, Because the solar is not enough to run the whole system for a hours of times, I mean the PC side also. For this case I wanted to reduce the useless power of my system, and the other thing is if you set out this Automatic Eco-Link system once you don't need to do power up and down your system everyday. well lets have a look.
What we need
Software for control your PC for stand by to wake up mode
Interface circuit for your PC, D-sub (LPT) Port
Pin "B" is almost ground, and Pin "A" better you select it your self for the proper selection to your computer mother board. There are some little differences with the maker of the PC around the world. For my work I use Pin No: 17 as "A". Try not to BURN you PC mother board, careful not make short circuit.
