I have the jumper on the DSC's port.

What am I ding wrong? Should the LED be wired to the ground and signal pins?
The power stays on. Only the signal turns on/off. Whether or not the LED will illuminate when you connect it between signal and ground depends on how much current the LED requires to illuminate, and how much current the signal can source. What's the part number of the LED?
