SHIPMATE RS8400 HANDSET CABLE

John
Is that the DSC version of the 8400?
If so, there will be a "car radio" style box at the lower helm where you operate all the DSC stuff.
I assume you haven't got the 8400 DSC addon because it would have needed to be reprogrammed with your MSI.
I once had some notes on the DSC that explained how to reprogram without sending the unit off.
It involved setting a jumper inside the unit and powering up - then entering the MMSI as though it was new.
 
Not sure Mike, can't lay my hands on the manual at the moment. I located the control unit to disconnect the handset cables before soldering in the new sockets, images as below of control unit. AIS would be great but not got my head around the Furuno navigation kit yet, been out and it seems relatively intuitive, just updated the chart card for now. List of jobs reducing.....

No, John
I think you have the 8400 before they brought out the DSC unit.
If your 8400 had a DSC, you would have one of these somethere:-

You probably need one of my dAISy Raspberry Pi units - like the one that I put on the roof of the main building in Sant Carles Marina.
That way you could transmit AIS round the boat wirelessly.


Remember thats DSC - not AIS - AIS wasn't even heard of when they made the 8400!!
 
Just got back to UK, I just missed you this visit.

No, no DSC unit - I have a box of RPi's though, so would like to chat to you about AIS when we are next out together. I will probably keep the 8400 until it plays-up, then would go for the SH GX2100E or latest equivalent thereof at a later date, I will buy the hand held SH VHF with DSC (which I also had on the F43) for now.

I'm in Madrid end-of-March on business, but not sure if I can get down to the boat thereafter, we're next out in April, when I will run her down to Las Fuentes to do a fuel check, then hoping to trip over to Mallorca for three weeks in June, in convoy with Keith and Lyn. Best laid plans and all that.

Yep - I have two handheld Standard Horizon DSCs - great little sets.
DJEFABS bought the latest Standard Horizon GX1200E and the remotes etc.
He is planning on fitting his in March so you might like to see what has changed since the last one you bought - I believe that are a couple of differences.
RPi's
This is the hardware that I've used successfully - dAISy Hat that fits to any RPi.
The dAISy Hat is the red board on the left.

Here is it - all plugged together.

And here is a link to our SCMCHAT Live AIS Station - the above hardware with some dedicated onboard software.
Have a look at the weekly statistics - you can see by the number of AIS targets when the town's fishing fleet goes to sea and when they return.
Of course not many leisure targets at this time of the year.
Just thought it would be interesting to post this link.

Details for AIS Station Sant Carles Marina, Spain - VesselFinder

On the routing AIS wireless reception throughout the boat, instead of using the RPi solution, there are now some dedicated boxes that you can get from the likes of Digital Yacht but I just find it interesting building my own stuff.
 
I've not actually made one of these using an RPi yet but I use the software all the time and I used the hardware on the AIS station.
So, this is what I would do:-

I bought my dAISy Hat from here:-
dAISy HAT
I was told by a friend we both know not to bother with the pre-amp that they offer as an extra.
But I did buy the little plastic box that mounts the RPi and the dAISy Hat in a nice little box.
You will need a good VHF antenna set for the AIS frequency - a good marine VHF antenna is about the best you can do on your boat.
The coax will feed directly from the antenna to the dAISy Hat's antenna input.
You could use a VHF antenna splitter and share your existing antenna with the 8400 but that might cost as much as a separate antenna.

Then, I would power up the RPi and install Raspbian (Linux) onto the RPi.
The dAISy Hat outputs serial data into the RPi so virtually any software can read the AIS NMEA 0183 sentences sent from the dAISy Hat.

Now to the actual software.
I use Kplex which is an NMEA multiplexer written in software.
Open source free to use - See here Kplex: An NMEA-0183 Multiplexer
It runs under Linux but IIRC there is a RPi version for exactly this purpose.
You set Kplex up to receive any number of NMEA channels (even at different baud rates or different devices).
You can then set Kplex to output to as many devices as you like - again any baud rate or channel.
Now to the clever bit - Kplex also outputs (or inputs for that matter) to TCP or UDP (over a LAN)
Raspberry Pis Version 3 and above (more recent) incorporate internal WiFi.
So, using Kplex on an RPi 3 or greater you can send NMEA data over WiFi.
Two ways of doing this - either make the RPi a WiFi access point or get the RPi to connect to a "Ships WiFi Router" - @John100156 - Like the Buffalo router that you used before.

So, now you have NMEA data on WiFi (either as an access point or on a Wireless LAN)
You now need a program/device that will pick that data up and use it.
I'm not an iPerson but I run OpenCPN on Android and this works nicely - AIS on my Android Tablet for example.

I know all this works because my ships PC (running Linux) is set up to stream AIS continually across WiFi.
A little project that I have in mind for this summer is to get Navionics working again since the recent licence changes - it should be possible to get the Navionics App to read AIS over WiFi using Kplex. You would need to know the port number that they use and then just get Kplex to transmit using that port number - I think that they tend to use port number 10110.
As I say, it SHOULD be possible to get the Navionics App displaying AIS from a Raspberry Pi but it DOES work with OpenCPN on the Android.

So - over to you - iPeople.

EDIT
Of course, instead of a tablet/phone, a standard PC/Laptop running OpenCPN would pick up the AIS Raspberry Pi feed - and again, I KNOW this works.

Many thanks, I believe I understand all that you have said.

I will have a play: its the sort of thing I would really love to do, if only I can eke-out some time to play, but I will try. What with work (just 22 months to go,,,) 5 kids families and 11 Grandchildren (BTW has yours arrived yet?) and a boat to upgrade, spare time is the one commodity I have very, very little of...;-(

This is part of what John generously sent me over two years ago. Sadly reminds me it’s been that long since I’ve seen my boat. I’m happy to check the colors against pin position if that’s what you need. Please confirm

yes that's exactly what i need. how the colors are occupied so that I can solder it on.
