[CA] [CA11] EV150 AP Issue

[Chuck - Raymarine - Moderator]

greenbunch,

The autopilot consists of three major components, each having dedicated software. V2.18 is not the latest version of software for any of these components. The command sequence specified within my prior response may be used to determine the software level of the EV-1 CCU, ACU-150 and p70R/p70RS Autopilot Control Head. It would be recommended that the software within your autopilot's components be updated and that the actions specified within the FAQ found here be executed to address the issue specified. Please click here to view a FAQ addressing how one may update the software within these components when the system lacks a compatible Raymarine MFD.

Regarding speed, you have not quite addressed the question asked. While the third party chartplotter is certainly supplying the chartplotter with SOG from a GPS source, it may also be producing Speed (through water) from an instrument or fishfinder transducer featuring a paddlewheel. You may determine whether the autopilot is receiving Speed data by configuring the autopilot control head to display the Speed (not SOG) data item and then verifying whether it is being populated with data when the vessel is moving. Any reported Speed value other than dashes would indicate the autopilot is receiving Speed (through water) data from the third party chartplotter.
