Wouldn't it just be simpler to put on an N2K backbone? with an
N2K GPS?? A NMEA 183 GPS is going to need power anyway, so running
the power to the backbone is no more trouble than running it to
the GPS.? And it avoid cutting any cables.? If (big "if") the E80
will echo GPS to a NMEA 183 port, that can be wired to the NMEA
183 input on the DSC radio.
When I did this last year, I went with a standard N2K backbone
rather than Raymarine's proprietary connectors.? You'll need a
Raymarine spur cable to go from the backbone to the E80, but then
you're free of Raymarine cable prices.
OK, I can sense Allison smirking at this point, but N2K does
simplify low speed devices even if it can't handle radar, charts,
images, or sonar.
I'd advise against the E85001 route -- the wire connections are
fragile and irreparable. Might as well take Allison's advice and
join the early 21st century.

Had I known that the plotter was an E80, I would have also
added that it is compatible with the current Raymarine (Seatalk
ng/NMEA2000) RS150 GPS sensor which, although more expensive, is
compatible with new equipment going forward. The E80 Seatalk 2
Port recognizes most common NMEA 2000 sentences, but not AIS.
You would need a Seatalk 2/Seatalk ng Adaptor Cable for the E80
and then create a Seatalk ng Network (A06064, 2x A06031) to
support the RS150. I can¡¯t remember for sure, but the E80
Seatalk 2 port may also provide power as it is not truly an N2K
compliant port. If not, you would also need an A06049 Seatalk ng
power cable (I can get that info for you if you need it).
If you proceed with the SCU-31, you will have to cut off the
connector moulded onto the cable and look at the instruction
sheet to identify the power and data wires. You will then have
to connect it to the ¡°data in¡± pins of the E80 ?NMEA 0183 port,
for which you will of course need a suitable cable, which of
course is discontinued. If you don¡¯t have one and can¡¯t find one
online, I can probably help you out on that.
The other scenario is that the E80 only has 1 NMEA 0183 Port
and if it is being for AIS, it would be configured for 38,400 Bd
and not the normal ?4,800 Bd. If so, you can either choose to
forego the AIS feature or find a Raymarine Seatalk 1 to NMEA
0183/RS232 interface box (E85001). They too are discontinued,
but available used online. I think I have 1 or two of those
kicking around too, but I¡¯d have to test them to ensure
functionality.?
Bottom line is, if you have all these issues going on, it¡¯s now
getting to the point where adding an SCU-31 might not be the
cheapest option!
Sorry I was not in possession of all the facts, particularly the
model of Chartplotter, before making that recommendation, but
hopefully it¡¯s not too late to refuse the shipment if you feel
it is getting a little too steep a hill to climb to save $300 or
so.
