[CA] [CA11] auto pilot update

[Chuck - Raymarine - Moderator]

Mark,

Q1. I don’t see any reference to a part called “EV-1 CCU”. In you’re reply there’s no mention of the sensor.
A1. Prior generation of Raymarine autopilots combined course computations and actuator control within a single component known as the autopilot's course computer. Evolution autopilots delegate the course computation task (as well as roll, pitch, and heading sensing) into the EV-1 / EV-2 CCUs (Course Computer Units, also referred to as Sensor Cores). Evolution autopilots delegate the actuator control task (as well as rudder sensing) to the ACUs (Actuator Control Units). As mentioned within my initial response, if replacing the SPX-5 autopilot course computer, then it would be necessary to install an EV-1 CCU, and ACU-100 in place of the SPX-5 and to install a p70S (to support sailing to wind) in place of the ST6002 or ST70 autopilot control head which is presently installed onboard. Essentially, these are the components which make up the T70152 EV-100 Wheel Autopilot, minus the wheel drive itself. The part number for the EV-1 CCU (also referred to as the EV-1 Sensor Core) is E70096. The part number for the ACU-100 is E70098. The part number for the p70S autopilot control head is E70328. As these three components are designed to be interfaced as individual spurs to a powered and properly terminated SeaTalkng / NMEA 2000 backbone, additional spur sockets may need to be added to the currently installed backbone should it not feature a sufficient number of unoccupied spur sockets to accommodate these Evolution autopilot components.

Q2. That leaves the control head. Is the “sail to wind” function the only difference between the two? Can I use the current P70 if I don’t care about that function? Can I do what this with full axiom functionality?
A2. You initial inquiry mentioned a "P 60" ... Raymarine has not produced a product having this name. The p70 and p70S autopilot control heads are functional equivalents and provide the same features. The p70S has simply replaced the p70 to provide styling which is consistent with the eS/gS-Series MFDs and Axiom/Axiom Pro/Axiom XL MFDs.
