Just completed the install of a B&G Triton system on Crazy Fish.
The NMEA 2000 wiring is pretty simple and requires a minimum amount of cable runs.
The previous B&G Network system required a run from the wind sensor to the wind display, the depth sensor to the depth display, the speed sensor to the speed display and then if you wanted it a network cable to link the network display.
The Triton system using the NMEA 2000 network requires a network cable run that links all the devices. Think of it as each sensor and display is a node and all the nodes need to be linked. Terminators must be added at the two most further ends. The wind sensor includes a terminator and I added a terminator at the adjacent to one of the Tritons.
I purchased 3 of the Tritons to be installed in a Pod mounted at the front of the cockpit (tiller boat now). Might have been overkill, but I do like the 3 displays.
One normally display info from the GPS, one displays speed/depth info and one displays wind info.
Linked in the existing Garmin GPS with a NMEA 183 to NMEA 2000 converter.
Did run the NMEA 2000 cable to the wind sensor which required pulling the mast. May have been able to hack into the existing Datamarine but Crazy Fish mast had never been pulled since it was first floated in 1989. Use the mast pull to install new LED nav lights and spreader lights, pull the NMEA 2000 cable , replace the sheeves at the top of the mast (totally frozen), convert from external halyards to internal halyards and to replace all wiring in the mast.
I replaced the B&G Network system with the B&G Triton as I was removing the wheel pedestal setup and replacing it with a tiller. So needed to move the instruments and it was a lot simpler with the single NMEA 2000 cable to the instrument pod rather then the 4 cables the B&G Network required.
