Analog/Digital Outputs using NI DAQ

[LeoWinchMag]

While using NI USB-6008/6009, I am encountering a strange error which I have failed to find the source of it. As you can see, there are 2 types of outputs. When I comment out one of the outputs, other one works fine. However, when I use them both, it gives me an error as shown below in the picture. What could be the problem?

Error: Invalid data format for digital channel

However, the error directs to analog output.
