Hey all,
I’m looking for a pointer in the right direction. I have a Garmin transducer, this one:
https://support.garmin.com/en-US/?partNumber=010-10249-20&tab=topics and I am working on a home engineering project involving using this as a sensor.
I am just looking for any and all information about the data provided by this transducer. Some of my questions are: Is it truly NMEA 0183 compliant? Is it powered by 12V? Is there any info about the wires inside the cable which are red, black, white, and bare?
I know this is a fishing forum, but there’s so little information from Garmin or Google searches about it that I have to reach out somewhere.
For anyone curious about the technical nitty gritty, I have tried powering it outside of any water with 12V car battery and using the white wire as UART RX at 4800 baud per NMEA, and did not receive any data. There doesn’t seem to be an indication it’s even “on”, such as an LED or getting warm.
