Abstract: The technology provides for a power line communication system capable of providing data from a first device to a second device over a power line. The first device may include a set of contacts and a second device may include a second set of contacts. The second set of contacts may be adapted to electronically engage with the first set of contacts of the first device to form at least a power and ground lines connection. Circuitry within the first device and the second device may include circuitry for providing data over the power line connection between the first device and the second device. The circuitry may comprise a power line, a ground line, a transmitter line carrying data signals, a capacitor coupling the transmitter line to the power line at a connection point, and a receiver comprising two field effect transistors.

Abstract: The present disclosure provides systems and methods for activating a general purpose input/out (“GPIO”) pin. The system may include a control device, agency device, and a controlled device. The agency device may be part of the controlled device or it may be a separate device. The agency device may receive a communication signal transmitted from the control device. The agency device may count the number of pulses during a certain period of time to determine a GPIO pin to trigger on the controlled device.
