Wiring Yeoman Sport

[erbster]

I'm hoping someone knowledgeable can help me.

I recently bought a Yeoman Sport cheaply on eBay, which comes with a short yeoman to garmin lead.

Having determined that it works, I want to make a better job of the wiring, which entails making up a new cable. Having bought on the cheap, I did not feel like springing 40 quid for a yeoman cable.

I want to connect the yeoman to my garmin GPS 76 and a repeater. The yeoman comes with a power cable and a garmin cable, so that the garmin is powered by the plotter, but then I lose my cockpit repeater.

I have deduced (using a multi meter) the wiring of the yeoman to garmin lead- 4 wires: garmin nmea out to yeoman nmea in and vice versa, 12v+ and the fourth appears to be a ground, connected to three of the yeoman pins.

I have obtained a suitable plug for the yeoman, but I have several questions:
1. What sort of cable should I use? (4-core screened, at a guess- is the screening important? Do I wire the screen to anything?)
2. Can the yeoman be powered by this lead, making the other 2 pin plug redundant?
3. I assume that the repeater and yeoman are wired in parallel to listen to the GPS? Would I be able to get a dsc radio to listen as well, if I bought one later.

I know that that's quite a list of questions and I think I know the answer to some of them, but I am looking for some reassurance and yeoman have not replied to my emails.

Any assistance gratefully accepted.....

The yeoman manual has most of the answers you need.. See page 50

The power socket is wired in parallel to the other one, so can provide power on either.

Thanks Northwind. I looked in the manual, but wanted to be sure which *pin* was which, the manual assumes one bought the yeoman cable.

Thanks for comment on he latter, that's really helpful

I had a Garmin 152 feeding a Yeoman Sport, a NASA GPS repeater (the best thing they make! Excellent!) and an MTech DSC radio simultaneously with no problems. The GPS also acquired waypoints from the Yeoman and the NASA would display navigation to them.
I had separate cables to each device all emanating from a little box full of connectors behind the nav table with the +/- 12V in it too.
I used overall screened for most connections. The cable on the NASA repeater is 2 core screened overall but uses the screen as the -ve.

That's encouraging news, Troubadour. Thank-you.

Agree with your comments on the NASA GPS repeater.

I think I'm ready to make up the cable now; will then have to wait until weekend to connect it up with the rest.

Thanks for your comments, both.
