P70 No pilot error and mode page blank

rlschmidt,

As indicated within my prior response, communications between the Evolution autopilot components may be blocked if each is not operating with the latest version of software. This is certainly the case for the autopilot control head and ACU. It is recommended that the software within each of the Evolution autopilot components be updated accordingly. Also as indicated within my prior response, it is advisable that only the MFD and the device to be updated be connected to the SeaTalkng backbone. The SeaTalkng Power Cable packaged with the EV-200 autopilot may be used to power the SeaTalkng backbone when the ACU-200 has been disconnected from the backbone. After individually updating the software within the Evolution components, then they may all be reconnected to the SeaTalkng backbone and an Autopilot Factory Reset should be commanded via the autopilot's control head.

Please additionally note that your diagram indicates that the Termination Plug (blue) has been inserted into the unused spur socket of the p70 Autopilot Control Head. Should this plug actually be a blanking plug (black), then it may remain within the p70's spur socket to protect the socket. However, should the specified plug be a SeaTalkng Termination Plug (blue). then it must be removed from the p70's spur socket.

Should the problem persist after addressing the above listed items, then it would be recommended that the EV-1 CCU be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
