Hello,
Yes, the Lab-PC will allow you to read in a signal from a function generator. To do this, you will want to connect your signal up to the analog input channels of your device using a connector block. Besides the Lab-PC device and your function generator, what other hardware do you have? You'll need to have a cable and a connector block as well in order to connect the signals from one device to the other.
To learn more about making signal connections, locate your device's product manual at
ni.com/manuals. The manual will show you a pinout of your devices as well as discuss the different ways to connect an analog input signal including grounding issues.
When you installed NI-DAQ several example programs should have been installed. Depending on what programming language your are going to use will determine the examples you have available. If you are using LabVIEW or CVI, then you can open the example finder from the Help file and locate an Analog Input example. If you are using a text based language such as C, then you can find examples in the /National Instruments/NI-DAQ/ directory on your drive.
You shouldn't need to do any configuring in MAX besides adding your connector block as an accessory to your Lab-PC device. You should use MAX however to test your device to make sure that the hardware works correctly and you have proper signal connections. You will want to do this by using the Test Panels in MAX.
I hope this helps you out. Good luck.
