I think he is asking what you have for a DAQ card. What card did you place in the computer and hook to the BNC-2110?
Since you are using this connector block, you can create a signal with the Simulate Signal Express VI and then send it from the computer through your DAQ card to the BNC-2110 by using the DAQ Assistant Express VI. The Signal output of the Simulate Signal VI should be wired into the data input that will be created on the DAQ Assistant Express VI (after you have configured it). Depending on what you are trying to do with it, you may need to put the whole thing in a loop.
