If the base of the transom has a radius, fill the gap between the
transom and the paddle wheel bracket with sealant. This will help
ensure a smooth water flow.
Run the cable connector and smart module over or through the
transom. If routing through the transom, drill a 7/8" (22 mm) hole.
Make sure the smart module is inboard, and not left exposed on the
transom.
Caution:
If you drill a hole in the transom for the cable, make sure it is
located
above
the waterline. After installation, be sure to seal
the cable hole with the same marine grade above-or below-
waterline sealant used for the screws.
Route the sensor's cable connector to the T on the network backbone where
you intend to attach it, and plug it in. The sensor is now ready to use.
Connecting to a NMEA 2000 Network
A network bus is an installed and operational network cable (backbone)
running the length of your boat, already connected to a power supply
and properly terminated. Such a bus provides network connection
nodes at various locations around your boat.
This is similar to the telephone wiring in a house. If you pick up a
phone in your living room, you can hear someone talking into the phone
in the bedroom.
Network Nodes
A network bus is built of network nodes spread along a backbone.
Network nodes are made by fitting T-shaped connectors into the
backbone (using the sockets on the sides), and attaching a display unit or
sensor at the bottom of the T.
Using our telephone example, the T connectors are similar to telephone
jacks. The backbone is like the phone wiring running through a house.
Phones in a house must be connected to each other to communicate, and
