Garmin 192c gps to Mtech 500 VHF radio help?!
Can anyone give me some suggestions for hooking these to up together? They are both already wired up to their respective power supplies.
On the garmin gps I have the following cables:
Red- power (already connected)
black- ground (already connected)
Blue- nmea out (com1 Tx)
brown- nmea in (com1 RX
Green-nmea out (com2 TX)
white-nmea in (com2 RX)
yellow- alarm low
On the vhf radio I have:
Brown-nmea Rx +
Red- nmea Rx -
Orange- nmea Tx +
Shield- Ground/Tx -
The vhf then has a separate black and red power supply which is already connected up.
Having read both the manuals which werent particularly helpful, I'm now thoroughly confused so any suggestions would be much appreciated!
