Adding Devices, a Network Node or Extension Cable
NMEA 2000 devices are added to a network by connecting the device to the bottom

have its own T connector on the network backbone.
You can add a node or extension cable to any existing connection, anywhere along the
network backbone as long as each end of the backbone ends with a terminator.
