The short version:
What do I need to get the raw data (speed and temp) from my Airmar DST800 to be NMEA 0183
for the chart plotter?
The long version:
I have a DTS800 with 7 wires--I know what part of the data they all carry-- and I want to send the the depth
to my ST40 head
(which I know how to do-blue/black/screen) and I want the send the depth
, speed and temp to my JRC1800 chart plotter , which has a NMEA 0183
input. How do I covert the raw data from the 7 wires to NMEA
so I can plug
it in to JRC1800?
Thanks for your ideas and expertise.
