Both modules plug into a standard AC outlet. On the bottom of the SPIM-01 is a standard RS-232 DB-9 connector which is attached to a serial port on the computer or NetPlace server using the appropriate cable.  On the bottom of the UPIM-01 is a standard USB connector which is connected to a USB port on the PC.

The physical design of the SPIM-01 module provides optimum flexibility by the use of a pass-through electrical plug with a non-controlled outlet on its face, resulting in no loss of outlet availability for other household devices.  The UPIM-01 does not have a pass-through receptacle.

The UPIM-01 is ideally suited for use when setting up or modifying a UPB network with UPStart.  It is not recommended for use with a home automation controller.

The key to both module’s function is the Universal Powerline Bus technology for communication applications. Use of standard electrical wiring for communication transmission is possible due to lower noise levels, stronger signal strength and improved reliability surpassing technologies such as X-10, CeBus and others. UPB technology also allows enough individually addressable devices to control the largest residential environment usually without the need for phase coupling and without affecting or being affected by adjacent home environments.
