|...The B&G NAC-3 Autopilot Computer...|
|Setting up the tees and preparing for backbone in the sail locker|
Here are some photos....
|The computer and all the connections|
|Notice the drawing is backwards with the screws on the top....errror.|
My wiring is correct and the part is correct, I need to alert B&G.
|I wired the NAC-3 upside down as it was easier to make the connections.|
|There it is, all connected. the power, drive ram, ground wire and NMEA 2000|

|Working in the sail locker on my back with NAC-3 on my knee|
|Once wired, we mounted it to the wall where the old ACP-1 was located|
|This is a NMEA 2000 Maretron Wire bundle, pairs are shielded|
|We had to cut one end of the GPS feed and install our own NMEA 2000 end|
|4 wires with one screen, Red/Black & White/Blue + Screen|
|The end fitting installed|
|The end was needed to make our GPS connection to the network.|
We have never built a NMEA 2000 network before, but now we can see WHY it was developed. Using a backbone design and using Tees to connect devices to the network, the network topology is really simple. You can tee in up to 50 devices on one NMEA 2000 backbone. We will have 13 devices total, so we are nowhere near capacity of this network. We are learning a lot and it is exciting to be setting up and installing all this new gear. Again, thanks goes to Colin Mack of Mack Sails. We bought everything from him and we would do it again in a heartbeat. He is so great to deal with and he is very helpful.
