I'm trying to figure out if the Logic passed from the dvd to the mobo is active high or low. I plan on building a pcb to pass this information to the mother board so evox will quit freaking out. I plan to use a flip-flop triggered by the eject signal to toggle the tray status. I also need it to hook up pc dvd drives. By active high I mean that TRAY_IN is 5v with the tray in and by active low I mean that TRAY_IN is 0v(gnd) with the tray in. Can someone check this please? Also, I need to know what the level is for the eject signal passed to the dvd drive.
