lowrance lcx-15-mt has rs-232 i/o....for what?

[BullGator]

Just installed a used Lowrance lcx-15 gps fishfinder. It has a wire for rs-232 output in the power/data harness. Anyone familiar with this? I have looked at the manual online, no mention of it. What is it for? Thanks......

Got it I think....I can send data to a logger or PC, then use software to view trackpoints, waypoints, etc. Thanks.
