i have just bought some new stuff and want to conect them all together i hav cp180i plotter st2000 tiller pilot standard horizon vhf dsc do you just basicly add all the matching colours of wire together what type of wire do i need to extend this
i have had a look at the manuels but still not sure any tips would be great

*Not* matching colours - I guess 'cos it's NMEA in->out and vise-versa.

I followed the above and got my 180 to talk to the 1500 (& Mic) no problem - haven't got a smart enough tiller pilot. I used 4-core (or maybe 6-core) alarm wire (& heatshrink, etc) from B&Q to extend the *data* run.

(But I did check it with an old car battery at home before carting it all to the boat & fitting it)
 
It is certainly not same colour connection, even with two bits of SH kit.

You need the hand book for each item and identify the correct wires on each bit of kit. The SH wiring diagram is reasonably helpful but there is no standard colour code
 
Scrim,

I have got a similar setup on my boat. CP180i, ST100 tillerpilot but the radio is a furuno RO4700.

The connection between the radio and the plotter is similar to the Standard Horizon wiring diagram referred to in mcframe's post above. It works well sending GPS to the radio and returning GPS data from incoming DSC calls which are shown on the plotter. Why the engineers at SH made the wiring colours different on their VHF and the plotter is just plain daft.

I took a different approach when connecting the pilot. As I have Raymarine wind instruments and log, I wanted to get wind data to the pilot so the pilot will follow the wind, and also gps speed data to the log so I get speed over ground (GPS) and speed thru water (paddlewheel) on the deck displays. So I connected the pilot to the ST60 instruments using Raymarine Seatalk, then I fitted a Seatalk/NMEA data converter to interface the NMEA data (Plotter/VHF) with the Seatalk data (Raymarine). I think raymarine do a suitable converter but I used a product from Gadgetpool

This little box also provides a serial port so the connection of a laptop in future should be easy.

I haven't yet sent waypoint data to the pilot so I con't confirm that the plotter can control the pilot but as all the other NMEA data is on Seatalk I'm sure it will work.

I used CAT5 cable for the data connections. I don't think the twisted pair is necessary, I just had some CAT5 cable spare and so I also have spare cores if anything is needed in the future. The pilot power (+ & - 12V) needs at least 1.5mm cable, and maybe 2.5mm if the pilot is a long way fom the batteries. This is the down side of the ST1000. The mating chassis socket provided with the pilot has very small cable entries and it is very difficult to get the cable into the terminal hole. If you are not carefull the terminal screw will back out, fall on the floor, and disappear. A bad choice of connector. I assume the ST2000 uses the same connector.

Hope things go well

Mike
