User manual LOWRANCE NMEA 2000 EXTENSION CABLE AND 120-OHM TERMINATOR

[. . . ] We designed these cables to allow you to configure your NMEA 2000 network to best suit your needs. Depending on the equipment you want to attach to your network, you have several options available. In order for your network to operate, there are a few rules you must follow. Terminators In order for the network to operate, you need 60-ohms of resistance attached somewhere on the network cable. [. . . ] Follow this rule: · Always make sure your NMEA 2000 network has all of its plugs attached to something. As an example, let's say you've got two GPS display units on your boat, and you want them both to receive signal information from one GPS receiver. You can't simply disconnect the 60-ohm terminator from the Yadapter and connect the second unit, because then you'd have no terminator. Instead, disconnect the 60-ohm terminator and connect the included NMEA 2000 network expansion cable (as shown in the following figures). Network socket Figure 1 LGC2000 Primary GPS unit Two 120-ohm terminators Lowrance NMEA 2000 expanded network with two 120-ohm terminators. Secondary GPS unit 2 Figure 2 LGC2000 Primary GPS unit One 60-ohm terminator Secondary GPS unit Empty socket Lowrance NMEA 2000 expanded network with one 60-ohm terminator. Either of these configurations will work. As long as one of the units (and only one of them) has the NMEA 2000 Power cable connected to a power source, the LGC-2000 will operate, and both units will receive position information from it along the network. However, as shown in Figure 2, using one 60-ohm terminator leaves an empty, powered socket. Remember, you can use either one 60-ohm terminator or two 120-ohm terminators, but always make sure every plug on the network is attached to something. In this example, your network would be set up with two different GPS units (or sonar-GPS combo units, or one of each) both receiving GPS signal information from the LGC-2000. If you wanted, instead of a secondary GPS unit, you could have the extra network port attached to a NMEA 2000 temp sensor. Then your sonarGPS combo unit would receive both the GPS signal from the LGC-2000 and the temperature information from the temp sensor.

NMEA 2000 temp sensor 3 Or you could connect two sonar-GPS combo units to the network, and also attach an LGC-2000 and a temp sensor. To do that, we use the same cable configuration, but replace the two 120-ohm terminators with one 60-ohm terminator (as shown in Figure 2 earlier) and attach the empty socket to a temp sensor.

When attaching terminators, you can only use either one 60-ohm terminator or two 120-ohm terminators. So if you have a full network using two 120-ohm terminators and you want to add one more sensor, just remove both terminators, attach the sensor to one socket and the 60ohm terminator to the other. If you wanted to add another port beyond that, you'd have to buy a new network expansion cable, and switch back to two 120-ohm terminators. You can continue expanding with network expansion cables until your network contains everything you want to include. It includes two different temperature sensors (one at the water surface, for instance, and another in your live well) as well as the reading from a paddlewheel speed sensor on the transom and the GPS signal from an LGC-2000. The network would then share all of this information with a sonar-GPS combo unit mounted in the dash, and with a smaller sonar-only unit at the stern and another up on the bow by your trolling motor. In addition to all the units and sensors, you'll notice it includes two 120ohm terminators, and three network expansion cables. There's virtually no limit to the expansion possibilities, but we do recommend you keep your network to less than about 300 feet (about 100 meters) of cable.
