Controlling on National Instruments device

Hi,

I have National Instruments (NI) device (NI 9375 + cDAQ-9171 Chassis) for controlling on Pneumatic manifold.

The target of the NI device for my application is only to pass/not pass (on/off) 24 Volt to the Pneumatic manifold using computer.

I saw that Matlab recognized the device, but I would like to know how can I run the device through Matlab?

What are the commands for using the device via Matlab?

Thanks,

Itai
