NMEA Signal Monitor
Near the NMEA terminals in the junction unit you will find a
green monitor LED (Refer to Distribution Unit Terminals, page
17). A flickering LED indicates that a NMEA signal is received.
It does not, however, qualify the contents of the message.
Note ! Do not confuse this “RX” LED with the LED marked “TX”. The
“TX” LED will always be lit/flickering when the autopilot is on.
NMEA Port Test (JD5X hardware)
Disconnect the cables on the Main PCB in the distribution unit
and connect TX1+ to RX1+ and TX1– to RX1–. Similarly, on
the Power PCB, connect the NMEA ports the same way: TX2+
to RX2+ and TX2– to RX2–.
Loopback NMEA1 OK
Loopback NMEA2 FAIL
NMEA PORT TEST
Under SERVICE in the Installation Menu, select "NMEA PORT
TEST" by pressing the (STBD) button and confirm this by
rotating the course knob clockwise.
Verify that the hardware is OK. If not, replace the corresponding
PCB(‘s).

A Master Reset 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 not clear the stored compass calibration and
offset values in RC25, RFC35, JD5X and GI51.
