Light-O-Rama can control industry standard X10 modules using CM11A X10 controllers (available for purchase at a variety of online stores). The X10 CM11A tab of the Light-O-Rama Hardware Utility can be used to test the connection and functionality of such controllers.
To do so, first connect the controller to a serial port, using the cable supplied with the CM11A.
Select the port that you believe the CM11A to be on in the "Select CM11A Port" dropdown list, and click on the "Init Unit" button. In the status window above the port selection dropdown list, you will see if the unit has been located on the selected port. Note: Occasionally there will be a false report of a CM11A being located on comm ports that are actually internal modems. This is generally Comm 3.
Select the house code and unit number of the controller, and test the unit using any of the "On", "Off", "Fade Down" and "Fade Up" buttons.
