Pcs2

flcusat

Could somebody explain how the outputs of the PCS2 behave when sensing a device conected to it?

Well, let's say you plug in a CD player. Normally with the power button off both outputs are open, when the players powered on, paused or stopped (system stby) output 2 makes/closes and output one stay open. When playing or FFWD/RWD output one makes/closes and output two opens. It may be reversed but I think that's right. So you basically have three possibilties to track: both open, one open & two closed or one closed and two open.

But when it is closed do you have any voltage or viceversa? How do you combine the status of the output on the PCS2 with an I/O port?

Two different ports.
