Furuno GP-35 to Laptop

Hello All... great site you all belong to!

I have found a few good ideas on this site, but one topic which still baffles me, is how to connect a Furuno GP-35 to a laptop...

Here is what I know, you can connect the cable to a RS232 connector then to a RS232 to USB... if needed...

What I dont get is what pins to use and what order... the schematic diagram say I must use Blue yellow and Green wires... COOL! But what about the white... so I leave that alone...

According to the diagram Blue which is SG, is pin "2" Yellow which is RD is pin "3" and Green is SD so according to this diagram it must be the three middle pins?

Can anyone confrim this?

It's been a while since I did this but I think you've got it right.. Neema ?? only needs the 2 wires to the right pins. The real problem I had was telling the computer which usb port to use and the correct baud rate from the gps.I mounted the 9 pin right into the dashboard which is well protected from wet.I run a designated laptop on Windows 98 for an older Nobletec program. Nearly bullet proof.But have to watch out for errors near the quilted chart edges.Cause rocks are bad.
