temperature transducer

[dr john]

Thanks for your reply. Not great at the technical aspects of seatalk but the boat was rigged by YF (2010) with all Raymarine electronics including radar, sonar and auto pilot. Since the current transducer is still reading incorrect seawater temperature, can that be turned off so the MFD could read the temperature only sensor. Read in saltwater magazine about the I70 can be set up to just to display and graph temperture. I don't think the MFD that i have can do that. Not sure I understand what I need to have a properly terminated SeaTalkng backbone, so this can work. RM doesn't have a temp sensor only do they? Thanks for you help
