Why the driver was not working was solved: I was using PCI-MIO-16E-1 with Elvis.
On Elvis, the digital lines on the box are not directly connected to the
MIO device. In fact, there is a special serial protocol that is necessary
to turn a digital line on or off on the Elvis box. This is the reason that
the Elvis application can manipulate the lines, but I had not been able
to manipulate the lines with DAQmx, VISA, or driver in this thread.
On the other hand the analog is directly connected to the MIO; that's why
I was able to acquire an analog signal using DAQmx.
IMy driver is working correctly; however, the
solution is I need a different hardware accessory for testing such as a CB-68LP connected to LEDs.
