I currently have NI BNC-2110 connect to the NI USB-6255 which is then connected to my computer.
My goal is to generate a digital output through the NI BNC-2110 and then read the output on an analog input on the same NI BNC-2110. (The perpose of this is to make sure that I know how to properly output a digital signal and can input an analog signal, and I figured this would just check both things simultaneously.)

The setup works when generating a digital signal and reading an analog when I use the software NI MAX, my problem is when I try and do the same thing in matlab.
Here is my current code in matlab:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

d = daq.getDevices
s = daq.createSession('ni');

addAnalogInputChannel(s,'dev1', 'ai0', 'Voltage');
s.Rate = 8000;

q = daq.createSession('ni');

addDigitalChannel(q,'dev1','Port2/Line0:0','OutputOnly');

for p = 1:1:100

outputSingleScan(q,1)

pause(0.1)

data = s.inputSingleScan;

data



outputSingleScan(q,0)

pause(0.1)

data = s.inputSingleScan;

data

end

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

My current results are an analog input of ~0 Volts, and what I expect is a square wave from my analog input.

Any help on this would be much appreciated.
I am expecting somthing with a syntax in matlab with port to be the problem, but not to sure.

Thank you, Avery
