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).
