Es127

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Wildride1,

Of the products which you have listed , only four feature an Ethernet communications interface: eS127, eS128, SR150, and CP370. Each of the MFDs feature two Ethernet Network sockets. These will be used to interface the MFDs to one another. The remaining Ethernet Network socket of one of the MFDs will be interfaced to the Ethernet Network socket of the SR150, and the remaining Ethernet Network socket of other MFD will be interfaced to the Ethernet Network socket of the CP370. Appropriate lengths of RayNet (F) to RayNet (F) Cable will be used to network these products to one another.

One of the MFDs (to be designated as the system's Data Master), EV-1 Sensor Core, ACU200, p70R, Ray70, and VV7's (assumed to support NMEA 2000 via its NMEA 2000 socket ... check with Mercury Marine) will each be interfaced as spurs to a powered and properly terminated SeaTalkng backbone. Raymarine offers SeaTalkng Spur to DeviceNet (F) and SeaTalkng Spur to DeviceNet (M) adapter cables to support interfacing third party NMEA 2000 products (ex. VV7) as spurs to a SeaTalkng backbone.
