DAQ Card does not work

Hello everybody,

I am using Matlab R2012a with the Real Time Windows Target Toolbox on a Win7-64Bit machine. I have two Data-Acquisition PCI Cards installed from the vendor Advantech:

- Advantech PCI 1710L (Analog input) - Advantech PCI 1720 (Analog output)

Both are plugged in. The AI-Card works fine. I only used a analog-input-Block in Simulink, connected to a scope. But the output-Card does not output a single millivolt. The card is installed (ass shown in windows device manager), the AO-Block is set up with this card and the simulation is running (Normal-Mode). No error occured.

But des oscilloscope connected to the right channel (i tried every) is not measuring anything.

Does anyone have an idea of what might be a solution?

Thank you very much!
