I have a Northstar Explorer 567 Chartplotter
, and a Autohelm
, I have found online an owners manual for the St4000, and it says it accepts data from NMEA 0183
output Northstar uses APA, APB, BWR, GGA, GLL, GSA, GSV, RMB, RMC, VTG, XTE. attached is the data that the ST4000 works with, the Northstar manual says to use the white and yellow wires for NMEA
output, I hooked these up to the ST4000, switched them round, but it does not work, have switched on NMEA
output, and enabled all the output codes, but with no result. before I spend the money
to get someone down to have a look, thought I would ask here first.
