She's a Bermuda 40 Yawl, with legacy B&G sensors. In discussion with Eric Steinberg of Farralon US, we are planning to remove everything except the Masthead wind sensor and replace with current model H5000 "Hercules" kit for club racing, incidental shorthanded daysailing and coastal cruising.
There's a 2002 Vintage Interphase "PCView" transducer mounted just before the keel that gives forward looking and +/- 45 degree side to side scan sonar. Plan is to display that on the Zeus2 Video on cockpit bulkhead as needed when gunkholing and use a Raymarine CAM100 mizzen mounted below the Radome/Hailer for forward looking Daylight/IR Night vision. Eric's advice was to use the Maretron SSC300 in place of the R42N.
Furuno Navtex has been in the box for 10 yrs waiting for install, plan to connect it to the NMEA 0183 feed from H5000, and provide a WiFI-1 bridge for slaving Ipads to Zeus2 displays, as well as browser access. The Actisense EMU and tank levels are future project.
Any thoughts on better topologies/materials/units are welcome.
]]>Now, when we bridge them the networks, everything is visible, and data flows well, with one exception: the i60 will not display its own Ray wind data until we remove/re-connect the drop cable from the Ray bus to the i60; it then works fine for 15-20 minutes, and then loses the data and disappears from the NSS8 Device List. With the networks unbridged, the i60 performs as expected. The bridging wiring has been double-checked.
Raymarine says they know of no report of such behavior on the i60 and they agree that properly connected, the setup when bridged should work fine..
Anyone have any pointers about what we might do to de-bug & perhaps solve this?
]]>Also wondering if anyone is using a WSO100 on a Seatalk NG network? I've read that NG is supposed to be NMEA2000 compatible, can I just hook it in and expect it to work, or does it require it's own NMEA2000 backbone which is then connected to the NG backbone?

]]>I have a question about VHF antenna mounting locations. I realize the best location is up high. My carbon mast is 70' above the water. But with that distance and corresponding reduction in power, plus weight of the cable(s), desire for AIS-B, a Lopolight and Airmar PB-200, is it feasible to mount the VHF antenna on a radar mast which is 10' or so above the water? My thinking here is that with less power loss and a higher quality antenna, the effective range may not be substantially different (or substantial enough to be a practical hindrence to coastal New England cruising) and the cleanliness of the installation/maintenance is a valid trade-off.
Thoughts?
]]>Even if NMEA2000 is meant to be "plug-and-play" I see one major problem with choosing another brand. All calculated wind information, such as True Wind etc, is calculated from boat speed but the calibration of the boat speed is stored in the instruments and not in the sensors unlike, for example, depth. In the network only the measured boat speed is distributed and not the calibrated one.
When I calibrate the boat speed in one of my IS20 Graphics the wind information on the Wind instrument will change accordingly. It is not, however, possible to make the calibration in the Wind instrument itself so if I were to put the instrument in a network that would not have any Simrad instruments I would not be able to calibrate the boat speed in order to make the IS20 Wind instrument show the correct wind information.
The reason I have previously been looking at Garmin's GMI10 is that it is also capable of showing boat speed, which therefore must be possible to be calibrated. I have also looked at Furuno and Raymarine but I have not been able to retrieve enough information about their instruments to judge whether the boat speed can be calibrated in their wind instruments.
Has anyone else tried to combine instruments from different brands the way I am describing above?

It looks fine to me, though I wonder if all the field attachable connectors along the backbone are necessary. I think they're valuable if you have a tight cable run, but otherwise pre-made cables are easier, more robust, and less expensive. I'd also flip some of those tees around so the gender progression was more orderly. It's a nuance, but the idea of the Maretron power tap with its two female connectors is that cable genders go M/F/M/F/M/F all the way from there to terminators and all devices. That way if you ever break open the network when it's powered up you won't expose male pins that are hot. There's no good reason I can think of to have M/M or F/F cables.

]]>I have a SimNet network on my boat with a Maretron DST100, a Simrad wind vane, a compass sensor and a GPS antenna connected to a couple of IS20 instruments. Now I wish to add a GMI 10 to this setup.
I have a NMEA2000- to-SimNet adapter that I used to plug into the GMI 10 and a T-joiner in the network. It has an NMEA2000 plug at one end and a SimNet plug at the other. If I understand it correctly, all I would have to do was to press and hold the power button to fire up the instrument but nothing happened!
I have made sure that there is 12 V in the connector and have double-checked with the installation guide that I should not use the supplied power cable if I am connecting the GMI 10 to an existing NMEA 2000 network that is already powered. The adapter I am using works fine for powering the Maretron DST100 hull sensor so I don't see why it couldn't power the GMI 10.
Could anyone give me a hint about what I am doing wrong here?

- Design out any unnecessary components for cost savings
- Ensure that it's expandable in the future (using mid-cable as backbone)
- Decide between a Airmar PB 200 on the mast or a Furuno FI-5001 Wind Sensor (Would go with FI-5001 to reduce cost)
- Ensure this is the smartest design for my application
I've already decided on/purchased the FI-501 Wind and FI-503 Digital and have a Airmar DST-800 installed in the vessel (N2K version, not hooked up to anything right now).
I'm planning on going with a Lowrance HDS-8M chart plotter but am open to options.
I plan on using the HDS-8M as the GPS sensor, making the assumption that it will feed the GPS data onto network to be read by my Mac laptop running MacEnc.
Couple of questions:
The airmar DST-800 claims a LEN of 4 (http://airmartechnology.com/uploads/brochures/DST800.pdf) while the Maretron DST100 claims a LEN of 1 (http://www.maretron.com/products/pdf/DST100-Data_Sheet.pdf). That seems strange to me?
The HDS-8M claims a LEN of 1. That seems low to me, I am assuming this is because the HDS also has a separate power hook-up.
If I end up going with the Furuno 5001 as my wind sensor, will it feed the data onto the N2K network via the daisy chained FI-501?
Is it better to go with field attachable cabling or pre-built N2K cabling?
What is the best way to go from the N2K to 0183 to USB for Laptop? Could I wire the digital yacht 0183 USB to the 0183 wire on the HDS-8M and expect the HDS-8M to feed N2K data over to the 0183 port then to the laptop?

Ben, feel free to repost them on this forum, I just couldn't figure out how. {Done below, B.E.}
