Raymarine Evolution EV-1, Installation Instructions Manual

Page: 18 / 142

3.1 Product overview
Evolution is a system of electronic components that give you autopilot control of your vessel’s
steering system.
In conjunction with a compatible Autopilot controller, the Evolution components enable you to
directly control the vessel’s steering system and provide navigation commands, such as navigating to
pre-determined tracks and waypoints for example.
The Evolution system provides a number of features to ensure ease of installation and minimal setup:
• Flexible mounting options — The EV sensor can be mounted horizontally on a flat deck or
alternatively on a bracket, for mounting on a mast, wall or other vertical surface.
Note: The arrow on the front of the EV sensor must be parallel with the centerline of the
vessel and pointing towards the vessel’s bow.
• Simple connections — all Evolution system components are connected to a single SeaTalkng ®
backbone.
• High accuracy — accurate course-keeping, to /- 2 degrees, in all conditions.
• Built-in heading and attitude sensor — no additional fluxgate compass required.
• Automatic setup — no calibration required. The Rudder Gain, Rudder Damping, Counter Rudder,
and compass calibration settings required by existing autopilots are no longer necessary
The Evolution system consists of the following components:
Component Purpose
EV-1 unit AHRS (Attitude Heading Reference
Sensor) The primary heading sensor and course
computer, incorporating an attitude 9-axis
sensor. This sensor replaces the fluxgate
compass typical in existing autopilot systems.
ACU (Actuator Control Unit)
Houses the main power and drive electronics for
direct connection to a vessel’s steering system.
