Here's how to use the AN1004 to externally re-awaken a system after it has programatically shut itself down.

Set "downtime" to 0:00 (this will cause this phase to be skipped)

Set "uptime" to whatever you want the device to wait after target triggering

Set "hostwait" to "yes" (There is a menu item for this)

Make sure you activate the AN1004 with the PC in the "off/sleep" state - it will start the countdown right away.

When the count down is reached, the AN1004 drive the button to restart the PC then wait for notification to start the countdown again.

A notification is sent from a serial port by sending the character "R" (capital only) at 9600,N,8,1 through a serial port

This can be accomplished from a DOS batch file with the following 2 lines:

mode com6:9600,n,8,1,p

echo R > com6
