X10 - CM11A - ActiveHome Serial Plug-In Controller and Software - Quantity-1 - Removed from service. It was replaced since my last X10 devices were converted to Insteon. The CM11A is a few years old and was working well when removed from service. The unit is in the original box along with the cables and CD.
