I am have trouble understanding how to connect a 3 wire RTD to my 34972A data logger.  I have read:

I do not quite follow how these type of wiring is accomplished.

I have the 34902A and 34901A cards.  I am confused about the EX ports

Are the EX+ and EX- terminals the COMM port on the acquisition card?  or are they a second AN+ and AN- port?

When I get this wired do I use a 2 wire RTD setting on the SW?

Could someone sketch a quick wiring diagram for me (preferably with ports labelled as they are on my card)?
