Abstract
A two wire communication system capable of transmitting data and transferring power by the used of an electrical bi-polar waveform across a two wire conductor from a controller in communication with the two-wire conductor to at least one module in communication with the controller and capable of transmitting data from the module to the controller; and a remote electrical device in communication with the controller. Usable data may be continuously transmitted across the two wire conductor independent of and during power transmission between the controller and the at least one module without loss of data transmission time and without affecting the transfer of power to the at least one module. The data is transmitted across the two wire conductor to the modules by pulse duration signals at the same time power is transmitted to the modules. The system is capable of using up to 100% of transmission time to transmit data without affecting transfer of power to the at least one module.
