Smartcraft wiring-2002 Opti 225

Nos4r2 · 13 March 2013, 19:29

Anyone got any idea what wiring I should have? the original wiring was a complete mess and all that's identifiable is part numbers 84-859314 and 84-859315. It appears to plug into a 5 pin semi-circular rubber plug into the main wiring harness. Pic below.

I get the feeling I may be missing a large chunk of the loom.

Which part is this from? engine loom or boat. Its really hard to see from the photo!

Is that the additional loom for the tanks and paddle wheel?

Nos4r2 · 13 March 2013, 22:10

No, the pic is the ONLY wiring I have for the SC1000 speedo and revcounter.
I'll label up where I think the wires go.

Nos4r2 · 13 March 2013, 22:19

This is as much sense as I think I can make of it, labelling colours are as close to plug/socket colours as I can make them. The one that's connected together was like that on the boat before dismantling. The red goes into the heatshrink, it's just not obvious.:-

Yeah see that now. Same as mine. I will look at it tomorrow and let you know what is what.

Nos4r2 · 13 March 2013, 22:32

Thanks

What features are working on your gauges? As far as I know, everything on mine was working though I don't remember if the speedo worked.

All works on mine apart from speed which is done by the paddle wheel which comes up with a 'CHECK PADDLE WHEEL' fault soon after you turn on the ignition.

Nos,

There's a complete set of wiring diagrams at the end of the optimax manual - colours and all, it's a big pdf but you can download if from our boating resources page

Boating resource from the Northern Exposure Collection

will

Cheers UTT-it's answeredd my question as it's got the exact wiring loom in there that I have (page 504 on the 150/175 Opti wiring for anyone else ever searching for it)

Ok, next question. It's fairly obvious my speedo isn't going to work, but apparently I can hook it up to a nmea0183 output to pick up speed from the GPS.It's an input only to the SC1000 gauges.

So...
I've got the VHF currently hooked up to the NMEA 0183 in/out of the HDS7.

Can I split the 0183 output to get the speedo working, or would I be better off getting something like the Actisense NMEA 2000 to 0183 gateway to run the smartcraft speedo off the N2K network? Would I gain extra functionality from the gauges too?

Jizm · 14 March 2013, 17:19

I'll have to have a look at that link. Not sure if you can use the nmea on both though.

Nos4r2 · 14 March 2013, 18:09

Well.... I found a few forum posts from the USA saying the signal strength is enough from Lowrance kit to do it-and it works as it's only an out rather than a 2 way connection. I'll have to try it I guess.

Just go into the Calibration and turn off the paddle wheel then it will go away.

Any idea on my NMEA 0183 question Rob?

Not quite sure if it's what you're wanting to do Nos, but I have the Actisense NMEA multiplexer, it allows you to input several NMEA0183 inputs & share them out to various devices as NMEA0183, effectively splitting & combining as required. Let me know if you need further info. it works a treat.

Nos4r2 · 14 March 2013, 22:02

Thanks PD.

I think I've found my answer. Smartcraft SC1000 gauges need a nmea0183 signal set to 4800 baud.(the same as the GX1600 VHF I have, which is good).

Apparently Lowrance GPS units transmit with enough power to split the signal to 2 receivers.

Sorted! I should have working gauges and working DSC. I'll find out when it all fires up...

well please post pics but here snow weekend

Nos4r2 · 14 March 2013, 22:10

I'll try. Might take a while, I won't know if it's worked 'til I power the console up when it's all connected and on the boat.

Nos4r2 · 15 March 2013, 22:12

Ok, from intensive research so far.

You should be able to split the NMEA 0183 output from an HDS unit into 2 to run both Smartcraft and DSC.
In your GPS, enable NMEA output, set the baud rate to 4800, and enable the following sentences RMB, RMC (for the SmartCraft) and GLL (for the VHF).

NMEA data and
Hooking your GPS to the Smartcraft Speedo/Vesselview

are useful references.
