    Point 1 question

    I am installing a point 1 for use with my elite fs 9. Since I will not be using it with two units is it ok if I use the three way connector without something connected/plugged into the third one or is there a better connector I should use? Thanks.

    Did you already have a NMEA circuit in your boat?
    If not you will have to build a proper NMEA circuit. All tee connectors must be capped on the end with a resistor.
    Lowrance NMEA starter kit.

    It’s not a three way connector. Only one port should be used for a device. With a Point 1, you need at least two Tees in order for the network to operate.
    If you have integrity, nothing else matters. If you don't have integrity,
    nothing else matters.​

    Thanks the video is a big help.

    Another question, my boat is a 2006 and has a nema circuit but it has large blue color connectors. My point 1 has a much smaller connector so how do I tap into the existing circuit or do I need to build a new one? Sorry for dumb questions but I know nothing about this stuff.

    There used to be adapters to connect blue T's to red/black T's. or connect red/black devices to blue T's, I don't know of they are still available.

    It may be easier to change out the entire network to the newer style. You will need a T for each device and one for power and 2 resistors (1 male and 1 female) for each end of backbone. A point one with a head unit will need 3 T's.

    Put the power cord on a switch as the network will draw power all the time.

    The above video is not correct. He connected the power to a T end, it needed a resistor there. The power will need it's own T.

    NEMA NETWORK only comes ON when the machines are on.
    Switch? Someone correct me if I am wrong.

    Yep you are correct. He should have connected the power cord- connector into the top of the tee.
    I know the top of the tee is a male. Cant remember if the little swivel connector on the point one cable is male also. If it is I think this would work. If i thinking right he would need another blue tee to connect in the backbone to plug the point 1 into via the adapter.

    Ok why do u need two tees for system to function, direct connect to the point 1, cable, run line to console, tee up to unit, run power on to fusebox from other connection on tee, should work huh

    That’s not the way NMEA2000 works. I misspoke, as you actually need 3 tees since the Point 1 isn’t much use without a display. Only the “leg” of the tee is connected to a device or to power.
    If you have integrity, nothing else matters. If you don't have integrity,
    nothing else matters.​

    So i need a tee at the point 1, of course a cover for end of tee, cable to another tee, where I will tee up to display, another tee which has another termination plug, the power connecting goes to fuse panel from that tee and that’s it, actually ends of tee are used only as a continuation of the nema circuit, only loads connect, or power to the tee itself, all ends are terminated

    Do all point one units have a light on them to prove power

    Point-1 does not have any light.

    Do not use your old NEMA network; at that time the connectors were not water tight, and moist air would allow corrosion on the connectors that is hard to see, but causes all kinds of problems. Lowrance switched to red connectors which were waterproof, and now black connectors. Get a NEMA 2000 starter kit which comes with everything you need to go with your Point-1, except for "tees" for more than one head unit.
    ciao,

    Thanks that is exactly what I am doing, the starter kit that is. I am thinking of tapping into my LED interior lights for a switched power source, any problems with doing this?
