[DG] [DG] troubleshooting wind/speed st50 instrument

[Derek - Raymarine - Moderator]

HI Lazybones,
Thankyou for your feedback

The pin colours are described here and should help when testing the masthead transducer. our suggestion would be to make a short test cable using a 5 pin DIN plug socket, stripped down to enable the masthead Transducer to plug in to it and then connect the other end of the cable to the back of the wind display unit.

If you replaced the masthead unit complete, the old Trapezoidal cups would not fit to the shaft of the new transducer, so the new cups would have to be used with the resultant increase in wind speed. Note that displays from St60 onwards had calibration of the wind speed, enabling the correct wind speed to be displayed.

To connect the new i60 wind display into the ST50 system, you would need to cut the 3 pin SeaTalk plug off one of the ST50 displays and connect the bare wires to the i60 cable using a junction box, (Red to Red, Yellow to Yellow and Bare/ shield to Black)

regards
Derek
