Wiring NMEA 0183 to RS-232 (USB Adaptor)

[Eublem]

Hello, I bought a RS232 to USB cable on ebay. It has the wires Red, Green, Black and White (standard USB), but I cant find documentation on how to wire it to NMEA0183..

I have this Silva Nexus Bus that I want to connect the wires to:


Does anyone have a good idea?

You need the manual for that Silva Nexus.

I have an actisense NGT-1-ISO connected, red cable on 9 (in), yellow on 11 (out 20mha), Black on 12 (return).

So whats the USB's equivilant to NGT-1's color codes?

USB:
Black - Ground (same?)
Red - Positive 5v
White - Positive Data
Green - Negative Data

Edit:
I assume red doesnt have to be connected, so Green on 9 and White on 11??? ��

Edit 2:
On a second thought, is there a problem connecting two things on the same NMEA0183 (NGT1 and PC)?
