hi out there
has anybody replaced a Simrad WP32 with a raymarine evolution, please?
Is it possible to replace only parts of the old unit in order to save money and work?
(I have to go down this route since old parts for the Simrad  - in my case the inner guide ring which is broken - cannot be found any where in UK)
hat jemand bitte Erfahrung mit dem Austausch eines alten Simrad Autopiloten WP32  Gegen einen Autopiloten Evolution  von raymarine ?
thank you!
vielen Dank!
Wieland

Raymarine have their own protocol Seatalk in different variants.  You can get it to link with NMEA using a convertor.  I do not know whether that is sufficient to get the Simrad and Raymarine parts talking to each other.


You could try contacting Cactus to see what they think, as I bought a lot of new electronics from them last year as they were the best prices.

I have done this in my 342 some years ago. I have good news and bad news: The bad news is that you cannot re-use anything of the old WP32 unit, just throw it away or try to sell it. The good news is that you get a better autopilot with a great display and a very accurate heading sensor. You have to drill a couple of holes in the pedestal for an aluminum pin which fits into the rear of the drive unit, otherwise it's easy to install. The EV-1 sensor unit can be placed everywhere below decks, the ACU-100 likewise, but you'll need some free space on your pedestal instrument pod for the p70 control head. All 4 units must be connected by SeaTalk ng cables, creating a mini SeaTalk ng network. It you later decides to replace the Simrad instruments with Raymarine as I have done you'll then already have a SeaTalk ng backbone to which the new components can be connected.

Hi Gunnar
I just discovered your reply - thank you !
I indeed have come to just the conclusion you suggest:
Get rid of the complete Simrad WP32 and install the Raymarine evolution.
regarding Sea Talk: I had the old simrad Depth/speed/wind  last year replaced  with Raymarin 
Does this mean that Sea Talk has been installed on my boat already?
Also: I find it quite confusing that there are so many different kit assemblies offered for the 
evolution. Would I need a complete kit including cabling? 
thanks!

Hi Wieland,
regretfully there's a huge difference in system complexity between the Simrad and Raymarine wheelpilots. It might be that you'll need professional assistance to install the EV-100, depending on your experience in this field.
If your Raymarine i60 wind instrument is connected to the i50 speed display (to calculate true wind) then you have a small SeaTalk-ng network already in your pedestal instrument pod, but in order to install the EV-100 you need a lot more. A Seatalk-ng network consists of a backbone cable (blue plugs) and spur cables (white plugs) branching out from the backbone. You need to install a backbone cable from the instrument pod, through the pedestal and down below decks where the EV-1 and ACU-100 units have to be mounted, ref. picture below. Both units shall be connected to the backbone by a spur cable, and the backbone itself shall be terminated with a special termination plug in both ends.
In the pedestal instrument pod you'll connect the p70 instrument to another spur cable from the backbone.
You also need to supply separate 12 volt power to the ACU-100. On my 342 there's a dedicated autopilot power cable running in the black tube above the Raymarine units. I cut this cable, connected 12 volt supply from switchboard to the ACU-100, while the driver output from the ACU was connected to the remaining part of the cable leading to the pedestal. Then I connected the far end of the cable to the wheel drive's power cable.
I'm not sure of what exactly you'll need of cables, but I suppose you'd better get the complete kit include wiring, like https://hudsonmarine.co.uk/products/raymarine-evolution-ev-100-wheel-autopilot-with-wheel-drive-and-p70s-control-t70152.

Hope this helps a little bit.

Regards, Gunnar

hi Gunnar
Thank you very much for this!
Ok - I'll buy the complete set (Hudson seems to offer this at a competitive price) and will ask a professional contact I have here locally to help me with the installation
Thank you and best regards
Wieland

  YES. I have connected Raymarine seatalk ng. with Ev100 tiller pilot to NMEA 2000. Last year I connected B&G Triton 2 speed / Depth / wind
To my Simrad IS20 wind instrument + Garmin 551s Chartplotter which displays all data on other instruments. All connects easily with the correct adaptors.

I'm having exactly that done over this winter.  While I wanted to replace every single bit of the system to achieve the greatest effect, I was advised that without major surgery to the steering gear area, I'd need to keep the old Simrad drive unit due to the design of the H400.  I'm assured that while this will mean slightly slower response times, I'll still gain the many benefits of the rest of the system.  All other instruments were upgraded to Axiom/I70's 4 years ago.

Hi everybody and thank you for your responses!
here is my update:
Just as I was ready to indeed give up on  the old Simrad WP 32 and have a new Raymarine evolution 100 installed (following Gunnar's advice), I realized that my pedestal has no free space for the Raymarine control , the surface being taken up completely by the chartplotter. So back to the drawing board, so to speak: Hudson marine (very helpful indeed) said that there should not be a problem connecting the old Simrad control ( conveniently located on the side of the wheel ) with a Raymarine evolution 100  drive unit. To be sure I rang Raymarine who said (somewhat categorically) "no mixing of Raymarine devices with Simrad possible!. This afternoon I went to talk to our local very good chandlery (Fox's)  - They kindly unpacked a complete set of the Raymarine evolution 100 and looked at the drive unit, to find that it has a very simple electrical plug in for the power and would react to simple   - "right left", or  "steady"  impulses (which is all I get (and want) from the simple Simrad control). So their answer: Yes it would most likely work and they would sell me the drive unit only (Ca 650 Pounds). To make sure, they would within the next few days use one of their contacts at Raymarine to verify.
So far so good - I will keep you posted  - - -

Hi Wieland,
I have replaced my WP 32 on my boat some time ago with a Raymarine SPX 5 (the so to say older version of the ACU 100) and the steering motor mounted on the steering wheel, the so called wheel pilot. To connect Raymarine with Simrad was really NO issue at all, as they both are using NMEA 2000 standard. The only difference is, that they have different plugs. As I had some cables with plugs left from Simnet as well as from Raymarine I just soldered them together to make adaptor cables which connect both standards. It worked from the first moment. If someone tells you, that mixing both systems is impossible, he either has no idea about it or want's to sell you new hardware.

One thing which did not really work well is the wheel pilot, because it's too weak for that boat size. After some hours with 6-7 bft. the combined motor & gearbox was totally damaged. So I decided to install an ACU 200 with a Jefa DD-1 drive and this works perfect. Additional positive effect is, that do do not always hear the noise of the wheeldrive unit. So if you have not already bought the ACU 100, you might consider to buy the bigger ACU 200 as the ACU 100 is not able to work with linear drives like the Jefa is. As far as I know, the ACU 200 can handle the wheel pilot as well. To know is earlier would have saved me some money....

Heiko
