Both are class A AIS. It means these are receive only, so you can plot it into your chartplotter. As far as I know, only 162 can mix a GPS input at a different baudrate, and provide its NMEA sentence at the standard 38Kbps output (161 has a one single DB9 output), but that's not a problem if yor plotter has more than one serial input. Until now, FCC has not issued approval for Class B AIS in US waters, what people in the market just cannot believe how lazy they are for that. Class B will allow you to send AIS information as well, making you visible to other vessels too. Unless you have already one of them (162 is dual channel) I'd give up SRs, and wait for FCC approval to install a full Class B AIS.
