Abstract
A vision system for a vehicle includes an imaging sensor disposed at the vehicle and having an exterior field of view. A control is disposed at the vehicle and a coaxial cable is in communication between the imaging sensor and the control. The vision system communicates image data captured by the imaging sensor to the control and supplies power to the imaging sensor via the coaxial cable. The coaxial cable may include an inner core comprising copper, a dielectric medium, a foil screen, an outer conductor comprising copper, a separating layer and an outer sheath. When initially powering up the vision system, a transceiver of the imaging sensor may be tuned to an initial communication mode, which is suitable for communication with at least one of the control, a communication interface of the vision system and a display device of the vision system.
