Abstract: A data network may include a data bus and network nodes. The data bus may be a differential data bus having first and second differential signal lines that convey differential signals between the nodes. A bimodal impedance terminator may be coupled to the first and second differential signal lines at one or both ends of the data bus. The bimodal impedance terminator may include a first resistor coupled between the first differential signal line and a circuit node and a second resistor coupled between the second differential signal line and the circuit node. A capacitor may be coupled between the circuit node and ground. A third resistor may be coupled between the circuit node and ground in series with the capacitor. The bimodal impedance terminator may terminate both the differential-mode impedance and the common-mode impedance of the data bus to reduce signal reflections at the ends of the data bus.

Abstract: A connector system for transferring electricity and data. The connector system includes a receptacle and a plug. The receptacle includes a shield, a power contact, a ground contact, and a data contact. The shield includes power apertures through which power conductor segments of the power contact extend, ground apertures through which ground conductor segments of the ground contact extend, and a data aperture through which a shield member and a data conductor of the data contact extend. The plug includes another power contact connected to a power wire, another ground contact connected to a ground wire, and another data contact. The plug is receivable by the receptacle to electrically connect the power wire conductor to the power conductor segments of the receptacle, to electrically connect the ground wire conductor to the ground conductor segments of the receptacle, and to electrically connect the data contact to the other data contact, respectively.
