I recently purchased a Standard Horizon CPF300i chart plotter. I now wish to interface it with my 2 year old Standard Horizon GX1500E DSC VHF.

The problem lies in the fact that the colours in wiring looms for the two machines do not match.
Can anyone tell me in simple terms what colours from the Plotter connect to which colours on the VHF. I've spent about five hours today trying different combinations but cannot get the lat and long onto my VHF.

Your help will be greatly appreciated and will help save what little hair I have left.

Thanking you in anticipation.

Thanks

Thanks I'll try that tomorrow. I was hoping for an answer tonight, so that I could get the job done tomorrow.

Grant

It should all be here:

From diagram 5:
Plotter green -> VHF green
Plotter Blue -> VHF Grey
Plotter Brown -> VHF Blue

Therein lies my problem, the diagram in my plotter manual show Green, Brown and blue as the colours to use. The diagram on my VHF shows Blue, green and Gray as the clours to use from the plotter loom. What is likely to be the result if I correct the wrong colour, as I've probably done already. Will it resut in a short somwhere or just no signal? does anyone know?

Just in case it is a combination I've not used I will try your suggestion tomorrow.

Thanks David, the diagram you've posted is different from the one in my manual. I'll have a go again tomorrow.
Thanks again.

Hi mcframe,
The combination of your reply and David's diagram have hopefully given me the answer. At least the colours match. I'll keep you both informed.
Thanks again

You can connect the NMEA wires wrongly and they will not result in a fault, they are signal wires and tend to be isolated to prevent damage. I have spent many a happy hour trying different combinations in my boat and never damaged anything.

Grant, remember that you'll need to check that the plotter is set correctly for NMEA input/output - go into the Advanced Setup menu and check that the Port 1 settings are as shown on the diagram posted earlier.
 
While you're there, have you thought about adding an ANT200 AIS?

Just mount it somewhere, give it 12V DC and
AIS Grey -> Plotter Grey
AIS Brown -> Plotter Brown
(Or the other way round - it's just signal ;-)

Worth considering when you've got the tails of the CP300 multicore handy ~£200 quid, and adds AIS to your armoury. With recent SH plotter firmware, it shows arrowheads for AIS vessels that you can click on for more info, as well as a list if current contacts by distance.

A remote mic for the GX1500E is also handy.
 
Standard Horizon Wiring.

Thanks for all the advice given. Unfortunately none of it worked. The PDF wiring diagram is correct, but does not solve the problem. It seems that there may be a fault in either the cable from the VHF or the cable from the Plotter. After a couple of hours and three phone calls to the S/H help line and trying a number of suggestions I was told to
connect the common green wires to the negative side of the power cable. This worked and brought in the co-ordinates from the GPS.

I now have an integrated system. The question now is: Do I permanently wire the common greens to the negative of the power cable, or will this cause problems?

Thanks again for your help.

It shouldn't be a problem to leave it as it is, bearing in mind it's working. Is the plotter powered from the same supply as the radio?
 
Just connected a GX1500 to a Garmin GPS. NMEA data on Blue wire. What threw me was that the green NMEA common on the radio needed to go to the negative of the battery. The GPS did not have a separate connection for NMEA -, it was taken internally to battery negative. Did that and Lat and Long appeared! That was after setting the output to NMEA.
 
I had a similar problem connecting my C80 to a SH 2100 radio, it was complicated because I has an Actisense multiplexor in the way. It turned out after many hours that I had not pushed the wire far enough into the 3M Crimp connector I used at the plotter end. So I was effectively running it with one leg dis.

It worked fine connected directly to the radio as I grounded the green but would not work at all with the Actisense because that has fully isolated inputs.

As for your issue, personally I would have one quick look to see if the cable is dis but if its not obvious leave it as it is it will do no harm and it works.

I connected up a 180i plotter, mounted at the wheel, to a completely different make DSC VHF, mounted at the chart table, last summer. All I did was follow Standard's plan for VHF out and matched them to the VHF manufacturer's colours for NMEA in. Seemed to work fine once correct baud rate had been set. It's worth checking this setting, as the set won't process the signal if it's not right, and you'll think you have the wrong connection when it's actually fine.

I do find, though, that the VHF occasionally gets its knickers in a twist if I start the engine while it's on, losing signal from the plotter. Turning it off, waiting a few mins, then turning back on again seems to sort it.

Good luck!
 
Hi Thanks, Yes I've done that. It appears that there is a wiring fault somewhere in the loom. Connecting th common green to the negative results in a ling between the plotter and VHS.
I've managed to get a lat and long with this workround.
Thanks again
