Seatalk to RS232 to USB to PC

I am connecting a Raymarine E85001 to seatalk in order to connect my PC using Chart Navigator Pro and get data from all ship's NMEA instruments. From the E85001 manual I see that the DB-9 is connected to the E85001 RS232 output using pins 2 (Rx data) and pin 5 Ground. To send NMEA back to the Seatalk network It looks like they simple connect the DB9 (Tx data) to the NMEA input port on the E85001 and again pin 5 for ground. When I look at the special cable that Raymarine sells, I note that there are two pairs connected. Does anyone know if blue and black wires on the Raymarine cable (E86001) are shorted or both connected to pin 5?

After I verify this connection, I am using a Keyspan RS-232 to USB connector to get the data to and from my PC, that of course only has USB serial ports.
I have verified this bridge using my Garmin GPS. It works perfectly.

I had all of this stuff except the E85001 lying around so I figure I will do it this way until I am sure I know how to accomplish it over the Seatalk2 (ethernet) bus. (AND before anyone says it, yes I know I could also do it with Bluetooth).

I'd bet the wires are shorted, but you can easily check that using a multimeter.

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.

Yep, if I owned a cable I could check it with a MM. What I was hoping is that someone out there had done this very thing before and knew that RS-232 and Nmea ground are common.

Cable

Hi Chip,

I was wondering if you have ever solved this. I have the same question. What is the wiring schedule of this cable?


Kind regards,

Gaston
