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?
