Radar

[KREW2]

I mentioned on another thread I am looking at fitting a Raymarine Element 9 with a Quantum radome in my boat to replace my C80and Pathfinder scanner.
This wont be linked in to the old seatalk, so it wont get data from the St4000+ heading sensor, so I can assume MARPA will not work. Not a big issue as I am also going to add an AIS transponder.
I do like the ELB and VRM feature on radar. What I want to know is will it work without me having to go to the expense of fitting a second heading sensor.

I would get a ST1 to STNG converter and set it up properly. I have AIS and it's great, but in poor vis there's no beating MARPA. Overlaying on charts also needs a good heading, and if you upgrade you really want chart overlay, it's the absolute best reason to buy new RADAR

Without heading input you are back to the old fashioned relative display, MARPA will not work. EBL and VRM will still work, and there will be no difference in the VRM reading. However your EBL is taken from the heading marker (ship'shead) so any yaw in your heading will cause a target's relative bearing to change and wander off the EBL when in reality it may have a constant compass bearing. The radar will still be useable for assessing CPA, but will not be as intuitive or easy to interpret as with a stabilised display.
Your choice, but if you want a display that is easily understood without constant monitoring you need a heading input.

Does Quantum work with an Element 9? I was told that it doesn’t…..?

PS: Ignore - Seemingly it does……

Just before Christmas it was possible to buy a Doppler radome for a similar price to non-Doppler - Black Friday deal. Might be worth checking if that offer is still available, it was Cactus Nav I think.

ST1 to STNG converter I assume will let the ST4000+ talk to the Element9. Not something I can do myself so I will mention it to the installer chappie. Thanks.
What does STNG stand for?

SeaTalk 1 to SeaTalk Next Gen (aka NMEA 2000). The device literally just plugs in between the two and acts as part of the backbone of the new stuff. I used one on my boat briefly when I had olf ST60 displays with a new B&G MFD. I later replaced it with the iTC5 which allows the sensors to connect to the network without the ST60 displays.
I assumed you're keeping the ST4000+ so the cheaper converter box will work.

It will, but it will also send data from the plotter to the AP, allowing steer to a waypoint or wind.

Worth noting that the new heading sensors are substantially better than the old ones.

 

[lustyd]

They are indeed, although the main benefit of that is the modern APs can hold a better course using a 9 axis sensor. In this instance the money is probably better spent connecting the existing AP since 9 axis will be more expensive and the cheaper ones are the same as the old versions in use. Unless an AP upgrade is in the plan of course, but OP didn’t suggest it was.

Thanks all.

The AP works fine, but the OP's money tree is starting to shed a few too many leaves. The AP is not linked to the plotter at present because of my seatalk fail and no fix on the plotter. Steering from the plotter is not something I am prone to do, so I am not too worried about that.
I know MARPA is a useful tool on the radar for CPA, but the AIS will cover that. Seems I will just lose the VRM and EBL facilities
Having said that I think I can conclude that by using a ST1 to STNG cable I will have all the old capabilities back without having to by a new heading sensor. Seems the way to go.
Thanks again

It isn't a cable, it's a converter kit.

 

[lustyd]

in fact, it's this converter kit

 

[KREW2]

Well £100 that's not too bad.
I have just watched a video of it being connected from an Axiom plotter to a radio. The trouble is I don't think my radio is connected to seatalk, it just has nmea 0813 wires for DSC function. Everything else has a seatalk1 three pin connector
If it is possible to link in, I'm sure my techy guy will have a solution cos it baffles me.

It's an easy fit, you make a single connection from the existing ST1 "network" to the converter and connect the Axiom to one of the N2K ports. Data will be exchanged between the two networks. The AP will send heading data to the network and receive data from the plotter. Wind, depth etc will also be available on the plotter.

 

[lustyd]

Agree with Paul, it's very easy to fit even for an amateur. The hardest part is having the wires in the right place in the boat. Your AP is almost certainly at the helm, while your old radar is probably at the chart table. You'll want your new MFD at the helm so should be easy to connect these two, but you will need to get the network cable for the radar to the helm.

 

[KREW2]

It's all fairly adjacent, the C80 is just in view on the right

 

[lustyd]

In that case the biggest challenge will be deciding where to put it, and that won't be very challenging!

If memory serves the ST4000+ must keep it's own power supply, which means you don't connect the power on the converter or the new side of the network. In English, this means that of the two cables in the box you only need one to connect to the old network with the 3 pin plug.

Apologies I posted the wrong kit earlier in an effort to give you a cheaper option. The correct one is here. They look the same, but the one I posted earlier was just a backbone kit, not the ST1 converter. Similar price too so double check before ordering.

Should be very easy. Fit the Axion in place of the C80 and connect the radar (you have to do that anyway). Fit the ST to STNG converter in the binnacle, behind the trim tab gauges (ish). ST cable from the convertor to one of the existing instruments or AP I assume they are all interconnected). STNG cable from the Axiom to the converter and fit the two terminators to the converter. If the converter does not take it's power from the ST instruments, fit the power cable, otherwise do not fit it.

 

[KREW2]

Thanks so much you two.
That kit looks so much more compatible. Looks like power supply into the white, yellow into the back of the ST4000+. I assume I will need another cable to connect the Element9 plotter into the other white socket?
