1. Try using the "Test Panel" for your device in MAX
2. Try using a simple shipping example for digital output
Both are "known good" ways to produce digital output. Then, once you confirm that your device can work, come back to your code.
Do you get an error at 'error out'? What is it?
Try doing these two things:
- designate digital lines as well as the port, "cDAQ1Mod1/port0/line0:7"
- when configuring the DO task, wire up the 'line grouping' input to designate one channel for each line. I think the unwired default is one channel for all lines, which will be incompatible with the N channel 1 Sample write.

CAUTION! New LabVIEW adopters -- it's too late for me, but you *can* save yourself. The new subscription policy for LabVIEW puts NI's hand in your wallet for the rest of your working life. Are you sure you're *that* dedicated to LabVIEW? (Summary of my reasons in this post, part of a voluminous thread of mostly complaints starting here).
