How to access 2nd Pnuematic Control

[ScottRandallWay]

Our robot features two pnuematic module controllers. We can access the ports on the first module properly (0-7). I am unclear how to access the solenoids hooked to the second unit. When you create a new Solenoid object one of the constructors takes a module number and a port. I assume I need to use this call and designate the proper module number. Am I on the right track? How do I figure out what the module number is?
