Delay - how long before the camera takes the first image. Long - length of exposure (the camera needs to be in bulb mode for this to work). Interval - the amount of time between shots. N1 - the number of times the above settings will run which can be once up to 99 times. Repeat - the amount of time before the program repeats. N2 - the number of times you want N1 to cycle through. N2 lets you run the program up to 99 times so you could take 9,801 photos maximum.

Interval - 5 seconds (to help keep the CCD cool). N1 - 40 to get 40 minutes of images. Repeat - 5 secs (the delay before it takes the first shot in the next cycle.
