Issues with Raymarine C120 & NEMA 2000

[Tashmoo]

I am having a Raymarine C120 installed on my Tournament 275 with the depth, weather, radio and gps options. My installer is having considerable problems with the communications between the Yamaha F350 and the C120. The data from the engine is available via a NEMA 2000 protocol but the Raymarine unit is having issues reading the NEMA 2000 even though their literature claims that the unit supports it. We have also had a very difficult time with using the Raymarine weather/radio module and antenna to supply the sat radio signal directly to the GW installed Kenwood radio without loosing partial function of the Kenwood remote control heads. Anyone out there having the same type of issues? My installer has been around for years and has a great reputation so I don't think the issue is with him but what do I know???

By the way there is no mechanical speed pick up on the Yamaha F350 so the speed signal to the Yamaha instrument on the dash must come from your GPS. That is what started this entire mess.

For what it is worth in my oppinion so far in this process Raymarine gets an “F” for product support. For the amount of $$$ I have dumped into this thing I hope the C120 works better then the support that we have received form the factory.

I can't comment directly on your situation, other than to wise you success.

I can say that I recently upgraded from a Lowrance LCX-19C to an LCX-112C, with NMEA2K. I do all my own electronics work, and had no difficulty interfacing the twin F150s to the NMEA2K network. The engine parameters are available on the LCX-112C, and the LMF-400.

Unlike the Lowrance engine interface for Suzuki, there is no "module" on the connector - it is simply a Yamaha plug on one end and an NMEA2K on the other. The engine signals are fully NMEA2K compatible/compliant.

So, I would have to surmise that the C120 is not really prepared to accept and display that information.

My LCX-112C takes the engine fuel rate from both engines, combines it, divides the sum into the GPS speed, and displays vessel nm/gal. The other engine parameters include temp, RPM, fuel rate, hours, oil pressure, boost pressure.

As to support, I had a problem with the port engine reporting itself as starboard, and vice versa. Worked my way through several support folks at Lowrance, trying several times to "reset" and "reinitialize". Finally they passed me to one of the LCX-112C engineers and she simply indicated that there is no way to change that - it is reported by the engines as set from the factory. So I switched the ECMs and all was good...

Again, best wishes,
