Common Question of Raymarine EV1 Sensor
What is the EV-1 Sensor Core?
The Raymarine EV-1 Sensor Core is a heading and motion sensor for compatible Evolution autopilot systems. It provides system data rather than steering drive power. Confirm network connections, mounting orientation, calibration, control head, drive, power supply, and marine autopilot controller compatibility before installation.
What does the EV-1 provide?
The EV-1 provides heading and motion information to compatible Raymarine Evolution equipment. Confirm sensor placement away from magnetic interference, network wiring, power requirements, software, calibration, and autopilot-system compatibility before commissioning.
Does it control an anchor?
No. The EV-1 supplies heading and motion data and does not operate a gypsy, drum, chain, or anchor rope. It is not an anchor windlass component. Verify dedicated controls for marine anchor retrieval.
