Matlab daq input and output issues.

I can't seem to get matlab to talk to the daq. I have it connected and got the analog input recorder working, but can not seem to get any output. I have tried the instrument control and can't get it to connect. With that issue I tried the regular programing way. Nothing seemed to work. I am trying to send out a sin sweep from 1 hz to 5000 hz if possible over 5000 seconds. If it has to be done in small segments of 1000 that would be fine as well.

Here is the code I was trying to use.

 a = 1
b = 1000;
t = linspace(0, 1000, 100000);
y = chirp(t, a, t(end), b);
plot(t, y, 'b*-');
grid on;

This code is for the sweep.

 s = daq.createSession('ni');
addAnalogOutputChannel(s,'Dev1', 0, 'Voltage');
s.Rate = 10000;
data0 = y
queueOutputData(s,repmat(data0, 5, 1));
s.startBackground(1000);
s.wait(100000)

How are you testing the generated output ?

What are the values of "s.ScansQueued" and "s.ScansOutputByHardware" properties of s, before and after the "s.startBackground" command ?
