[CA] [CA11] SPx10 upgrade

Welcome to the Raymarine Forum Rob,

Question - In the Evolution autopilot it calls for using an EV1. Does this unit do more than just the 9 axis sensing?
A1. Yes. In addition to 9-axis sensing, the EV-1/EV-2 CCUs are responsible for the course computation & correction aspects of a traditional autopilot. In legacy raymarine modular autopilot designs, course computation and actuator control were both performed within a single component known as the course computer (ex. Type 100/300, Type 150/400, S1/S2/S3, S1G/S2G/S3G, X5, X10, X30, etc.). Within Evolution autopilots, the actuator control has been broken out into a separate component referred to as the ACU.

An EV-1/EV-2 CCU must be included within every Evolution autopilot system.
