Programming Roco 10775 modules using a multimouse

[Pete Williams]

I know it has probably been covered in these forums before, but could some kind soul please give this old idiot a simplified run-down on programming two of these to operate points numbered 1- 16 ?
I know that each module is programmed as two groups  - 1-4, 5-8 and the second module,  9-12, 13-16
but how ? And do i have to have a point motor conected to the module when programming ?
Many thanks.
