Is data acquistion toolbox meant to work with only sensors and actuators?

Hi, i have just started learning data acquisition toolbox. when i go through the documentation i could see there it is mentioned only to connect with sensors and actuators, is it so?.

suppose if i have my own circuit board designed for a specific purpose and want to connect to with data acq hardware and do some communication, is it possible with daqtool box?

The toolbox is suitable for connecting through TCP or UDP.

You need to have a driver for connecting to A/D convertors, as the mechanisms for setting the acquisition parameters, triggering events, or reading data, are not the same for all boards. But if you are using one of the A/D boards that it already knows (such as one of the National Instrument boards) then the toolbox does not need to know or care what is connected to the analog input lines.

you mean that i can connect my own hardware with daqhardware and make some testing and acquistion , right?

If you connect your own hardware's analog signals to the inputs of a data acquisition board that the toolbox knows about, then Yes, you can do testing and acquisition. With some data acquisition boards, you would be able to use analog triggers as well.

If you want MATLAB to be able to control your device, then your device would need an analog or digital protocol for that (and an appropriate board that has outputs as well.)

What could be difficult is the case where the analog to digital converter is right on your device and you needed MATLAB to be able to talk to that converter.
