Abstract: The present disclosure provides a CAN network topology for an HVAC communication system. The CAN network topology comprises at least three primary nodes having a predetermined termination impedance and a plurality of end nodes coupled to each primary node, wherein the predetermined termination impedance is set to the optimal setting of 180 ohms. Advantageously, the present disclosure eliminates the need for physically setting CAN node terminations. This reduces install time and removes variability of the install settings. Further, removing this variability reduces the risk for post-installation call-backs due to incorrect system setup. The present disclosure optimizes signal slew rate, which improves signal reliability.

Abstract: An electronic trip unit (ETU) configured to trip a circuit breaker using power from an external device is provided. Additionally, a system for enabling an electronic control unit (ETU) to trip a circuit breaker using power from an external device is provided. Further, a method for enabling an electronic trip unit (ETU) to trip a circuit breaker using power from an external device is provided.

Abstract: A method for enabling an ETU to function as a host controller is provided. The ETU includes a power bus port, a current sensor input, and a power distributor coupled to the power bus port and the current sensor input. The method includes determining that a peripheral device is connected to the power bus port. The method further includes determining that sufficient input power is available to the ETU to provide an output power to the peripheral device through the power bus port. Additionally, the method includes providing the output power to the peripheral device through the power bus port.
