User manual LOWRANCE EP-25 SPEED

[. . . ] The cable length from the 1 connector to the smart module is 18 inches (46 cm) and from the smart module to the paddle wheel module is 10 feet (3 meters). The smart module converts speed data from the paddle wheel to the NMEA 2000 data format. This allows any digital gauge, sonar or GPS unit connected to the NMEA 2000 network to display the speed. The EP-25 Speed, like the other Lowrance Electronic Probe (EP) sensors, is designed only for use with a NMEA 2000 Network. [. . . ] 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 belowwaterline 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. 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 4 in the same way only sensors and display units plugged into the NMEA network can share information. Connections found in the middle of the bus will have one or more of these T-shaped connectors with the backbone cables plugged into both sides. Connections at the end of a network will have the backbone plugged into one side, and a terminator plugged into the other, as shown in the following figure. Cable from sensor or display unit T connector LEI or Lowrance device needs an open T. Terminator at the very end of the bus Backbone cable (to rest of bus) NMEA 2000 network node located at the end of a NMEA 2000 bus. Adding a Network Node You can add a node anywhere along the network backbone where a connection already exists. This connection could be at the end of the network (between a T connector and a terminator), between two T connectors, between a T connector and a backbone extension cable, or between two extension cables. Wherever you want to add the new node, simply separate the sockets of the old connection and attach your new T connector between them. Lowrance or LEI device connects to new T connector. Add T-shaped connector to add device to bus. Attach terminator at end of bus. Existing network node Add a new device to a NMEA 2000 bus by attaching a T connector between two T connectors, between a T connector and the end terminator, or between two backbone extension cables. 5 If you want to add a node at the end of the line (as shown in the previous figure) remove the terminator from the very last connector, securely attach the new T connector, and then attach the terminator on the new connector. Either method will allow you to add a device. The "soft" T connector, shown above with a "hard" T connector, is another option for connecting devices in a NMEA 2000 network.
