Installing a NavPilot 300 and wondering if SCX-20 will talk to the VX2. Would rather install a SCX-20 instead of a PG700 heading sensor for when I upgrade the VX2. Thanks.
Both the PG700 and SCX-20 are NMEA 2000 items. The Vx2 is a NMEA 0183 item. They will not directly communicate. A NMEA 2000 to 0183 converter would be required for either device to send data to a Vx2.
Yes in both cases you are putting the converter on the 2000 bus to pick up the heading infomation and then using the 0183 wires to drive the radar with heading data to the heading port.
