ST40 seatalk interface

Hi,

I have an ST40 Bidata and just installed an ST40 Wind. According to the website, you need to have an "E25028 Interface kit" to ties these together. Has anybody tied the Seatalk cables together (red and black to power and yellow to yellow for data) Would this work?

Cheers
Gary

meriachee-

do the instruments have a three pin Seatalk port on them??
If so, the cable from one can plug directly into then other.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Sailingdog,

Yes they do, but the anomaly in the ST40 series is that they have only ONE seatalk plug. My older ST30 had two plugs in the back of the instruments, daisychaining was easy. Raymarine now has this "interface" box that splits the bus. I'd be really interested in knowing if there's anything "active" in that bus box, or if it's a $30.00 passive splitter.....

The Seatalk junction boxes I have on my boat appear to be just three Seatalk plugs wired in parallel. Look like this:

Or you could just splice bare the cables ends and join them using choco blok connectors. The interface box is nothing but just connecting the wires together.

A terminal strip would work quite nicely as well.

I had same two instruments. I was told to connect the yellow wires and that no seatalk cable was required. This worked.

The power cable I believe had red, black and yellow. I cionnected the reds to power source and blacks to ground and the yellows together.

This costs NOTHING and works as well as Seatalk cable on ST40

Hi Mike, I am just about to buy a second display for my Bi-data Depth and Speed so I can have one on each side of the cockpit. Damn crew are always in the way.

Can I just connect them as you say? Also I am interested in getting the Raymarine Wind instrument but have heard that they are not very accurate? How have you found them?

Thanks
Gary

Thanks Mike, I was considering that the YELLOW was the data carrier and that the BLACK was power ground and data common. The way these are mounted in the boat leaves precious little space to start adding interface boxes, when it would be easy to splice the new cable into the existing one.

The ST40 Wind sure is a cool toy. It's not even calibrated yet and the boat's going faster..

I connected the cables together, Red to Red, Black to Black and Yellow to Yellow, and immediately the ST40 Wind would display "True Wind" which is an indication that the devices are talking.

Way cool.
