I am trying to figure out how the connections are made between the signal conditioning modules on my SC 2345 board and the board's J24 connecter and screw terminals. For example, I have an AI02 at channel 0/8 and I want to know where + and GND connect to this. Basically any wiring diagrams or tables with pin layouts will probably help me out quite a bit.

Is it not in the user's manual, or did I not understand your query?

Sorry for not being able to phrase my question more clearly. I have not been able to find any of the information I need on any data sheets or user's manuals. What I am trying to find out is basically how everything is connected. I want to know what the pins on the SCC module sockets on the SC 2345 board connect to on the rest of the board. My circuit has the SC 2345 taking some inputs from the J24 which are supposed to go through a signal condition module. I just dont know which pins on the J24 correspond to which pins on the SC modules.

Check out page B-2 in the SC-2345 user's manual: http://www.ni.com/pdf/manuals/371064c.pdf
You will notice that each analog input slot on the SC-2345 can output two different Nonreference Single-ended (NRSE) signals to the Data Acquisition board that is connected to the 68-pin connector at J24. If you have a SCC-AI02 connected to J1, then it has two differential analog input signals which are conditioned and passed to the DAQ board as two separate single-ended signals to channels AI0 and AI8 on the 68-pin connector. You can look up the e-series pinout with the e-series user's manual: http://digital.ni.com/manuals.nsf/websearch/05A25C65C755D8DB86256FD30081687D. You will see that AI0 and AI8 correspond to pins 68 and 34 on the 68 pin connector. Page 11 of the SCC-AI user's manual: http://www.ni.com/pdf/manuals/323089a.pdf describes the inner-workings of the module, which will also give you some additional insight into the connections.
If you are just getting started with SCC and want to know how to configure it in software, then there is an SCC quick start guide that may also be of use to you: http://digital.ni.com/manuals.nsf/websearch/5D08FA2610E23C4A86256FB1005880FA
I hope that helps.

Thanks for your help. Your reply was quite useful...from this point I should be good to go for at least a while now.

Well maybe one more thing...if you could direct me to a pin signal connection table for the TC02 module, I'd appreciate it. Thanks 🙂

Hello Charlie22,
There is a diagram that shows how to connect a thermcouple to the SCC-TC02 here.
Figure 2, at the bottom of the third page should be what you are looking for!
