Hello,
A fast method to look for the capabilities of your hardware, is to connect it to your computer and start Measurement & Automation. If the hardware is recognized, you will find it in the (left side) panel Configuration -> Devices and Interfaces -> NI-DAQmx Devices. (Optionally, you need to select from the drop-down menu View -> Refresh).
If you see the device, you can select it and go for its properties. This shows in the panel title the device name that has to be used for NI-DAQmx; typical "Dev1" or " Dev2". In the properties panel you can also select accessories such as an break-out box.
Next to the properties, you can select Test Panels. I assume that the 100 lines are mostly digital I/O lines. If you look at the test panel, it will have a tab for Digital I/O. This will show that (typical) there are multiple ports with each 8 digital lines. You can test your hardware and notice the syntax for NI-DAQmx such as "Dev1/port1/line0:7" or "Dev1/port10/line0:7".
Finally you have to connect the pins, cable or break-out to your own hardware. With most NI products, I found the pin layout in the device user guide. With a break-out, I always got a sticker with the pin layout. This layout also uses names like P1.7 for port1/line7 or P3.1 for port3/line1. Additional you will find (several) pins that can be used as ground.
If you specify you hardware and optional accesories by type/model numbers, I expect that NI people can guide you to the appropriate manuals.
Succes, Jos
