To run X10 with the controller you need to have a Control Interface
($29.95). Maybe you can get one from Ebay cheapper?
It will hook to your controller or Daisy Chain form you DC with a 4 cable phone cord. This is a standard phone cord, but some phone cords only have 2 conductors in them. You must have one with 4 conductors.
If you are using a DC, the DC must be hooked to the controller, then the Interface hooks to the output side of the DC.
Give your timmer a name say: MON%-M1
Use this code for the timmer: If Moon 000/000 Then MON ON
I don't know about the RC6500 x-10 wireless remote control system.
