How to trigger 5v -ve polarity from pci 6251 to sincronise the image capture ?

[shri]

Hello!

I want to synchronise the image capture of an IEE 1394 firewire camera with an 50hz input signal (acquired from Vsync of VGA port ). I want to accomplish this using PCI 6251 (SCB 68 E series) device. The IEE 1394 camera can be triggered using a 5V –ve polarity signal but have no idea how it is achieved, some examples about the application would be helpful

That's a example about use trigger signal without pci-6251.
