Near the NMEA terminals in the junction unit you will find a
green monitor LED (Refer to Junction Unit Terminals, page 86).
A flickering LED indicates that a NMEA signal is received. It
does not, however, qualify the contents of the message.

Power PCB, connect the NMEA ports the same way: TX2+ to
RX2+ and TX2– to RX2–.

A Master Reset is part of the final test at the factory, which will
reset the memories to factory settings. Unless you need to clear
all stored values during the installation set-up procedure, you
should not perform a Master Reset. A Master reset will also
clear the stored compass calibration values, except for RFC35R
Rate Compass values, which are stored in the compass.
