Where did you get the images and text you posted? Those illustrations are not shown in the owner's manual (that I linked to). Are they from the printed owner's manual that came with your radio?

Since the two documents presumably describe the same radio, it is not surprising they show the same designations for the NMEA-0183 signals.

Is your radio similar in appearance to the radio shown in the ICOM owner's manual (linked in my post above)?

I am surprised that ICOM is still using the obsolete NMEA-0183 unbalanced signals in their M412 model.

What is the approximate age of your radio?

You will find both the chart plotter and the radio listed in my NMEA-0183 Data Collection.
