I am looking to design a custom built infra red remote control for my pc, and the first function i am after is a remote power on capability. I would like to use the wake-on-lan port on my motherboard for this. I need to know what signal the lan card sends the motherboard in order for it to wake up. Is it a simple connection to the +5 rail, or is it more complex. can someone assist me with this please? |

The published descriptions I have seen suggest that after the NIC card has seen a 'Magic Packet' (containing 16 copies of its own 48bit MAC address), it starts up the ATX power supply. I would say it's most likely by pulling a line to earth. The connector is probably just across the 'power switch' line. Why not clip a voltmeter across the WOL connector and watch what happens when you push the power switch? (It's almost certainly a 5V pullup ... but careful). |

I was right ... I bought myself a present at Bookfind, and it has the pin map for the WOL connector. Pin 1=5VSB, pin2=gnd, pin3= WOL (active low). The 5VSB is the standby 5V for powerswitch and other such things (such as a low power supply to the WOL NIC card).
So just close a switch across pins 2 & 3 and the computer will start up. I would pulse it -- pin 3 might have to be high or floating for the computer to turn off. |
