How do I create a very accurate 50 msec pulse with a 1.05 sec period using a usb 6356 DIO port?

Using a usb-6536 card I need to create 6 synchronized DIO outputs that output a 50 msec pulse with a period of 1.05 seconds. It needs to have a 10 usec resolution. I have looked at the counter feeding the DIO examples but cannot get them to work. Not sure how to use tick counts or internal board clocks. I also need to sync the AI timing to the DIO output.
