Simrad RD68 - Garmin Interface

medicsailor · 16 January 2006, 12:40

Hi all, new to this lark, so hope someone can help.

Have got a Simrad RD68 DSC radio with a Garmin handheld GPS 48. Initially great, they both work independently, but I cannot get them talking to each other, so I can get the GPS position into my RD68 automatically.

I have the Garmin interface cable, which has 4 wires on it. White - data in PC to GPS. Black - ground. Brown - Data out - GPS to PC. and Red power (fused).

The Simrad has 2 leads coming out for the NMEA. Red NMEA out data (+). Blue NMEA out common (-).

The Garmin in the interface section is set to NMEA/NMEA 4800 bauds.

The stuborn things WILL NOT talk to each other. Anyone got any ideas please??

Regards

John

Brown to Red Blue to Black, GPS to Radio.

If that doesn't work you might have the wrong cable - make sure it has NMEA out (just because it will talk to a pc doesn't mean it will talk to a GPS) and the settings are the same on both units as well.
