Hello,
I have a
Garmin 43CV and want to tie it into
OpenCPN.
Would this type of cable/adaptor
work?
I am still quite new to all of this and appreciate the input!
Thanks!

NMEA 0183 Connection Guidelines
When
wiring NMEA 0183 devices, follow these guidelines:
- Transmit (Tx) (+) should connect to a receive (Rx) (+)
- Tx (-) should connect to a Rx (-)1
- Rx (+) should connect to a Tx (+)
- Rx (-) should connect to a Tx (-)2
1In the event the sending device has a Tx (-), but there is not a corresponding Rx (-) on the receiving device, leave the sending device's Tx (-) disconnected.Failure to follow this guideline can damage the sending device.
2In the event that the receiving device has a Rx (-), but there is no corresponding Tx (-) on the sending device, bring the Rx (-) to ground.
In general, designated ground wires (Commonly labeled: Common Ground or
NMEA Ground) on an
NMEA 0183 cable should be connected to a common ground. For specific
wiring information, please consult your device's
Installation Instructions for the associated wire colors.
