DSM 400

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Boatzguy,

As indicated by the Raymarine technicians with whom you have spoken, the DSM400 is not compatible (i.e. will not be recognized/utilized by the system for any purposes) with the a/c/e/eS/gS-Series MFDs. However, should you interface an a/c/e/eS/gS-Series MFD and the MFD to which the DSM400 is presently interfaced each as spurs a powered and properly terminated SeaTalkng backbone, then numerical depth data (as well as much other system data) would then be shared with the a/c/e/eS/gS-Series MFD. Data requiring very high bandwidth such as cartography, radar imagery, fishfinder imagery, SiriusXM Satellite Weather / Radio, IP camera video, etc. cannot be shared though this interface. Should it be desired to use the old MFD primarily as a fishfinder/chartplotter, then you may want to consider instead interfacing the radome/open array pedestal instead to the new a/c/e/eS/gS-Series MFD.

The transducers which had been designed for use with the DSM400 cannot readily be used with any other sounders. While it is conceivable that the currently installed 50/200kHz transducer may adapted to be mated to a CP370 Sounder Module (which in turn may be interfaced to the e165 MFD), Raymarine does not support such adaptations or slicing of transducer cables per the FAQ found here.
