From how I understand it the timers go between the existing connection on your light's cable, so you would need a patch cable with the male and female ends of the same type if you wished to extend it to a second light that's farther away from the timer. It would be pretty simple to make if places like monoprice don't already have one.
See, I thought they ran inline too but I wasn't sure which is why I originally asked. Looking at the pictures of the ramp timer it has a DC input from the light and and output to the transformer, so obviously my "plan" wouldn't work then if the Pro timer works the same.
If I do get another Sat+ I'll have to find a DC extension.
