cDAQ / NI-AnalogModules / list them and separate by type (input/output)

Hello!

I would like to program a little GUI, that shows me the Analog-Modules of a connected cDAQ from NationalInstruments. As my cDAQ is only supported by the session based interface, I have to use how described in the help:

d = daq.getDevices

Now I get the Modul-Names if I type:

modulnames = {d.Description}

But now the question: I have some input and output-Modules and only want to list e.g. the input-modules in a list.

How could I get a cell-array that only shows me the names of the input-Modules?

Anyone has got an idea?

I type

names = {d.Description}

and get an cell in that I can find the strings 'National Instruments NI 9201' and 'National Instruments NI 9263' for example. The NI 9201 is an input module and the 9263 an output module.

So, I want to create in my GUI two popup-menus. On one popup-menu I only want to see the input-modules, on the other I just want to see the output-modules. Now, to see what are input-modules and what are output-modules, I could type

info = {d.Subsystems}

But then, I first get out

[1x1 daq.ni.AnalogInputInfo] and   [1x1 daq.ni.AnalogOutputInfo]

In the workspace that is shown as another cell, but in each cell there is more than one information.

When I now type

info{1,1}.SubsystemType

I get the string 'AnalogInput' - but only for the first device. How could I get this string for all the devices in one step so that I can make a difference between input and output modules?

Ok, it seems nobody has an idea ... :-|
