synchronize NI 9514 with NI 9401 for digital output

Hi,

I need to write a code to trigger a laser for a PIV system. I'm using the NI 9514 with an AKD Drive to control a servo. I need to send a +5V signal to trigger the laser at a specific angle of rotation of the motor (This is repeated for every turn of the rotor). I also have the NI 9401 DIO. Any idea/example of how to do this will be much appreciate. I'm using the scan mode for the NI 9514, my system is a CRio 9022 with 9114 Chassis.

Thanks a lot!
