Network connection To enable echo sounder data to be viewed, the sonar module must be connected to a compatible Raymarine MFD / chartplotter. ContentsMFD / chartplotter network connectionThe RVM1600 must be connected to a compatible Raymarine MFD / chartplotter, via a RayNet network cable.Network cable extensionsWhen the required length of a single network cable run is greater than the longest available RayNet cable (20 m (65.6 ft)), a RayNet (male) to (male) adapter cable (A80162) should be used to join the RayNet cables together, to extend the total network cable length.Network connection to multiple MFDs / chartplottersThe sonar module may be used with multiple Raymarine MFDs / chartplotters, via a network switch and RayNet network cables. The sonar image can then be shared between multiple displays on the same network (providing that all displays are running compatible software).Parent topic: Network connections
