cRIO 9002 digital output

Hi,I'm trying to control some servos for my final project and i'm using labview 8.5, cRIO 9002, chassis 9102, and NI 9472 digital output module. I know it's kind of old but it's what i got. The main problem is that i can't find a way to control the servos using the digital output. I've searched everywhere and i still can't find a way. I'll be very grateful if you could help me, thanks.
