Raymarine network upgrade after SBS

[Nigelb]

In that case, why do you show ethernet cables going into it?

Good spot, I have confused the two schemes or options, the cable harness supplied with the Element unit has a combined connector for Power and NMEA 2000. The adapter was to connect this NMEA2000 connector directly to the Seatalk Ng backbone, assuming that the HS switch is redundant and removed from the system.

Thanks.

This is categorically incorrect. Seatalk is a proprietary Raymarine protocol and, with the exception of a few low-volume semi-hobbyist products flying under Raymarine's intellectual-property radar, no other manufacturers support it. Your Icom radio certainly does not.

Pete,

The VHF is definitely connected to the Seatalk Ng backbone, how else would it obtain position data to enable DSC functionality?

When you re-draw, leave out the hub and the green lines, except for one green line from the radar to the plotter.

Draw a blue line from the plotter to the right hand 5-way connector.

The centre 5-way doesn't need the Seatalk connection, it canm be a straight 5-way connector, same as the left one.

The Icom VHF needs a NMEA 0183 GPS feed. If you have not already purchased the AIS650, get the Em-Trak, it will connect to the STNg network (using a convertor cable) and supply GPS data to the VHF via its NMEA 0183 port.

If you already have the AIS650, you'll need a different solution. If you don't yet have the GPS receiver, it might be a better solution to fit an Actisense STNg to 0183 convertor.

Pete,

STNg is N2K with different connectors, the Icon that you have only has NMEA0183 connections. If it is currently connected to the old Seatalk network, it must be via a convertor.

Here is the spec for the M421 you say you have: https://icomuk.co.uk/IC-M421-Combined-DSC-VHF-Marine-Transceiver/4068/1209/104

Note the complete absence of either Seatalk, SeatalkNG, or NMEA2000 connections. It mentions only NMEA0183.

A more modern radio could connect to the SeaTalkNG backbone, because it's really just NMEA2000 with different plugs. But you stated that your radio needs a SeaTalk (not SeaTalkNG) connection, which is not the case for any non-Raymarine radio. You also drew it connected by a yellow line, which is the standard colour for the original SeaTalk.

Some confusion may originate from the fact that some versions of the SeaTalkNG / SeaTalk1 gateway can also operate in a mode where they output a subset of NMEA0183 sentences, instead of SeaTalk1, specifically to connect a DSC radio. But even if the radio is connected like this, it's not a SeaTalk connection that it needs, but NMEA0183.

I was thinking that the radar came with the usual Raymarine Cat5/RJ45 cable and that both "plotters" were actually plotters. In which case the generic hub/switch could be used and the radar cable would readily fit to that without any splicing

If you order the wired option for a Quantum radar, it comes with a long cable with Raynet both ends. Similarly the Axiom plotters (and I assume the new Element) use Raynet sockets for their ethernet connections. So if you did need a switch, you'd either use a Raymarine switch and all Raynet cables, or you'd use a third-party switch, cut the radar cable and fit RJ45s both sides, and use one piece to go to the radar and the other piece to the plotter.

All increasingly immaterial to the OP though, since he can just run the single Raynet cable from the radar to the plotter. The question-marks about connecting one plotter to the radar by wire and another by wifi go away too, since he doesn't actually have the two plotters he's drawn. The RayControl app running on the iPad will connect to the plotter's wifi, not to the radar, and simply share its screen rather than operating as a standalone radar client, chart engine, etc.

It's just 2 core i.e. a spliced pair into the a Seatalk cable direct into the Yellow SeatalkNg port, works fine.

Thanks Paul,

So here is everything captured at Issue 2.

I have removed the Raynet connection between the Radar and Element MFD and removed the HS Switch.
The MFD is connected to the SeatalkNG backbone (in the cockpit) via the supplied hybrid Power/NMEA Cable and Adapter. The RHS and central Seatalk connectors are part of the existing network, only the LHS unit and all associated cables are new. I have changed the VHF image and cable to represent a NMEA 0183 connection. Also corrected the erroneous VHF connection on the SeatalkNG central connector. The new AIS with its dedicated GPS will go into the central unit (behind the electrical panel). I will see if I can return the A650 unit as its new & still boxed, thankfully I have not purchased the HS Raynet Switch.

If this is approximately correct, then I will go and measure up cable lengths next weekend and also make sure I can physically run the additional power and network cables in these locations.

Appreciate the assistance and corrections from everyone on the thread above.

Out of interest, have any of the people proposing a physical cable for the radar data connection actually used the Raymarine radar under Wi-fi and hit any real world problems? Or is it just a theoretical concern?

My thinking was to avoid unnecessary copper cables and connections up the mast. So far Wi-fi for radar and for iPad connection has worked perfectly over 3 seasons.
Incidentally Raymarine advised me not to bother with RayView app and just use RayControl.

The yellow port is Seatalk1, the VHF needs NMEA 0183, i can't picture how this is working.

Your revised drawing looks about right.

Personally, whilst installing the radar i'd fit the cable, the wifi might work fine, but i'd like to have the security of a hard wired connection. I've not actually used one on wifi, any that i have fitted have been hard wired, but i have had experience with other wifi instruments onboard (wind etc) and they have not been 100% reliable.

You will already have two GPS sources on the network, the plotter and the AIS, so i'm not sure why you want to add a third ?

As i said in the previous post

"I've not actually used one on wifi, any that i have fitted have been hard wired, but i have had experience with other wifi instruments onboard (wind etc) and they have not been 100% reliable."

My thinking is, if you're running cables from the mast anyway, may as well have belt and braces.

I fitted a Quatum RADAR and Axiom last year. I use it wirelessly and have never had any problems connecting. Even in Port Solent and other marinas where you are surrounded by wifi signals. I appreciate that other people's experiences may be different. My scanner can be used either wirelessly or it can be wired. When I fitted it I decided that if i did have problems with wireless i could connect it with a cable. But have never had any problems.

 

[davethedog]

We had a new quantum 2 doppler radar and axiom 9 Pro mfd fitted in June and opted for the wired option just to be on the safe side as if you are running cables anyway it is only a small extra cost.

Just my thoughts ref this.
