24 Ray218 and Ray55 Marine VHF Radios
NMEA IN (from GPS)
Connect the NMEA OUT + and NMEA OUT – signals from the positioning device
to the NMEA IN + (gray) and NMEA IN – (purple) wires, respectively, from the
radio. An example of how to make the connections using a suitable connector
block is shown in the following drawing. For specific instructions how to connect
your particular GPS, please refer to the handbook that came with that device.
NMEA Alarm
When no valid position data is available, the NMEA alarm sounds (provided that
the MMSI number has been programmed): the GPS satellite icon flashes and NO
POS DATA is displayed on the dot matrix display. The alert tone sounds for 5
seconds or until you acknowledge it by pressing any key. The alarm repeats every
four hours, as long as the condition exists.
If desired, you can manually enter time and position data using the GPS/Time
Setup feature, as described on page 59. The alert repeats every four hours as long
as no position information has been entered manually. If position data is entered
manually but has not been updated during the previous 23.5 hours, all the
position (lat/lon) fields are set to all 9’s, time field is set to all 8’s, and the display
reverts to NO POS DATA.
NMEA OUT (to Chartplotter Display)
Connect the NMEA IN + and NMEA IN – signals from the chartplotter display to
the NMEA OUT + (blue) and NMEA OUT – (brown) wires, respectively, from the
radio. An example of how to make the connections using a suitable connector
block is shown in the following drawing. For specific instructions how to connect
your particular display, please refer to the handbook that came with that device.
