We have a need for a new gps sensor. The old one is labeled Seatalk ray star 120. Please let us know what current gps can be used with this old plotter
Thank you
Welcome to the Raymarine Forum GWB,

Raymarine's currently manufactured Raystar 150 GPS Sensor would be recommended as a replacement for your Raystar 120 GPS Sensor. Please click here to view a FAQ addressing how this sensor may be interfaced to your system.
Thanks Chuck.. can I just use a nmea0183 gps sensor?
Thanks again
GWB,

As the MFD features a NMEA 0183 communications interface, it would certainly be possible to alternatively use a GPS sensor having a 4800 BAUD NMEA 0183 communications interface with the MFD as long at the MFD's NMEA 0183 communications is not currently interfaced to another marine electronics device. Please note that the MFD NMEA 0183 Cable supplied with the C/E-Series Classic MFDs is no longer from Raymarine. The method initially recommended also has the benefit of supplying GPS data to the systems other devices irrespective of the power state of the MFD.
Thanks Chuck... is the nmea0183 the c-129 expects rs232 or rs422? My device puts out rs422 so just want to make sure the c-120 will accept that....
GWB,

Raymarine products such as its MFDs employ RS-422 for their NMEA 0183 communications. If targeting a NMEA 0183 GPS Sensor, selecting one from a manufacturer specializing in marine should ensure compatibility.
