I'm responding to this thread because I DO have a setup like you are envisioning and am somewhat frustrated by the data bridging capabilities. Maybe someone else can give me some pointers.
First let me say that Raymarine
produces some top of the line, bulletproof gear
and the C120W (with Radar
overlay) and the ST70 controlled SPX-10 Autopilot have already proven their worth to me on a boisterous delivery
up the Pacific coast. That said, they are pricy and it doesn't seem like they play well with others. Virtually all of their tech manuals
have exhaustive diagrams with "Ray-this" connecting to "Ray-that" (for several hundred more). But their info on connecting to others is virtually non-existant.
The AIS issue seems to be a non-starter without a third-party "MUX". I would strongly recommend Brookhouse, which I had on my former boat and which I may be buying
to solve the problems on this one. Even though the C120W can take a feed through a dedicated NMEA 38.4K port, AIS can't be sequenced into ordinary NMEA output data streams without a smart MUX. The C120W seems to be no exception here.
Forget the Ray E85001 mentioned below. I've got one on the boat and all it can do is convert basic St60 data into a serial
output for the PC. The Brookhouse can handle multiple NMEA "talkers", sequence full High speed AIS data into the normal NMEA stream without data "collision" problems, can automatically switch to back-up GPS
if your primary goes down and can direct separate output streams to multiple "listeners" (Like the PC and the DSC
Also forget the Seatalk
HS data network for PC unless you want to spend as much again on Raytech nav software
as you probably already have on Nobeltec
. although the dedicated Raytech will do some amazing things (like emulate a radar screen), you'll be paying through the nose for all the chart packages. My favorite value PC software
is Coastal Navigator. The logic is that when sailing in the really bad sh----, I want the radar overlay on the chartplotter
at the helm
. The PC is fine for downloading weather charts
planning and running performance logging software, but running down below to check the radar is a bit cumbersome and downright dangerous when short-handed.
MY frustration, for anyone who read this far, is I can't even get the ST60 sailing data on Seatalk2 to transmit over the ng network to the Chartplotter
. I've checked and rechecked the power supply conflicts, rewired the dealer install which powered Seatalk2 off BOTH the Panel and the SPX, and have the bridge cable running from the end of the Seatalk loop to the back of the ST70 controller, like all the pictures, but STILL can't get the data from one Seatalk network to the other.
If anyone has advice, I'd greatly appreciate it. otherwise I'm buying
another Brookhouse, ignoring all the fancy stiped wires and going back to running NMEA lines under the floorboards again.
