Actually it is the same, both state that the icom red is NMEA "IN" wire and the white wire is the NMEA "OUT" wire.

NMEA IN LEAD (Red)
Connect a GPS receiver for position indication.
• A NMEA0183 ver. 2.0 or 3.01 (sentence formatters RMC, GGA, GNS, GLL) compatible GPS receiver is required. Ask your dealer about suitable GPS receivers.

NMEA OUT LEAD (White)
Connect a PC or navigation equipment (NMEA0183 ver. 3.01 sentence formatters DSC, DSE compatible) for plotting position data received from other ships.

Thanks for the links I will look them over and see what I can come up with.
