Description
The Raymarine EV-1 Sensor Core (E70096) packs a 3-axis accelerometer, 3-axis compass and 3-axis gyro angular rate sensor into a sealed IPx6 puck just 140 mm across and 0.29 kg in weight. Monitoring pitch, roll, yaw and heading simultaneously, it lets an Evolution autopilot hold course to within +/- 2 degrees while it adapts to sea conditions without user calibration: the rudder gain, rudder damping, counter rudder and compass swing routines required by earlier autopilots are no longer necessary.
Installation is flexible. The EV-1 mounts on a flat deck, on the supplied wall bracket, or on a mast or bulkhead, above or below decks, and draws just 30 mA from the SeaTalkng backbone. It works with the ACU-100, ACU-150, ACU-200, ACU-300 and ACU-400 actuator control units and is operated from a p70s or p70Rs pilot controller or a compatible Raymarine Axiom, Axiom 2 Pro or Axiom 2 XL chartplotter. A rudder angle reference transducer (M81105) is recommended for optimum performance.
