How to enable NMEA output from C120W?

Andy,

I'm glad that we had time to discuss this issue over the phone. Per our conversation the NMEA 0183 output which you have supplied is being output from the autopilot course computer's NMEA 0183 output socket ... i.e. if you trace the serial data cable back to where it has been interfaced to the Raymarine system, you will likely find that it terminate at the autopilot course computer's NMEA 0183 Port 1. This port transmits NMEA 0183 heading (HDG) and rudder angle (RSA) sentences featuring the NMEA 0183 talker ID of an autopilot source (AP). I suspect that the serial data cable was installed to support a direct connection between the autopilot and the PC to permit the PC to function as the system's chartplotter should a failure of the C-Series Widescreen MFD occur.

Please click here to view a FAQ addressing how to interface a PC running a compatible operating system and RayTech RNS 6.2 software to a C-Series Widescreen MFD. This is the method for interfacing a PC running RayTech RNS 6.2 software would support not only communications of high bandwidth graphical data such as Navionics cartography, radar imagery, and fishfinder imagery, but also alphanumeric waypoint, route, gps, instrument, AIS, alarm, and system state data. It is recommended that the Ethernet cable at your PC's station be traced back to determine whether this cable has been interfaced to the Raymarine system in the manner specified within the FAQ referenced above. That said, the computer which you have recently acquired would not be supported for use the RayTech software because it is not only running the Windows 10 operating systems, but is also doing so via a Windows operating system emulation. As you have indicated that you have another PC which runs the Windows 7 or Windows 8 operating system, it is recommended that the other PC used accordingly. Should the PC lack an Ethernet socket, then it would be recommended that a USB 2.0 to Ethernet adapter be used to support networking the PC to your marine electronics system.
