Using a standard Ethernet Switch with NavNet 3D

​Yes, a 100Mbps Switch can be used.  Two pair Ethernet cable can be used between each NavNet 3D MFD and the generic Ethernet Switch so that the Furuno Power Synchronization signal does not interfere with or harm the Ethernet Switch. Failure to do so could damage the switch and any other components connected to it.   
Note: When a regular switch is used, the Power Synchronization will not fully work.  The use of the Furuno HUB101 is strongly advised for the NN3D.  It will allow power synchronization on the network and protect your equipment such as PC when regular CAT6 (4 pair Ethernet) cable is used.
