[CA] [CA11] CP370 upgrade on E120W

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum bobsled,

Unless the transducer's cable had been modified, there there would be no interfacing issue which may be identified for the reported symptoms. As the CP370 is interfaced to the MFD via Ethernet networking, communications between these two devices is essentially an all or nothing situation. Based upon the symptoms reported, it appears that the CP370 has been correctly interfaced to the MFD and these two devices are properly communicating with one another.
