I have an 1197c SI on the way. I need one NEMA output for Smartcraft guagess and one in/out for DSC on a VHF radio. Is this possible on an 1197? If so what cables do I need to make the connections? I read in another post that someone was able to get AIS to display. With a NEMA in/out connection will the 1197 display position info recieved from the DSC on an incoming call?
