Press ENTER again to
initiate Sky Search. The
receiver searches for
satellites in a prescribed
pattern until one is located.
The ALM COLLECT message
appears on the display
when a satellite
has been located and
acquired, and the unit is
collecting an Almanac. DO
NOT turn the unit off until
this message disappears.
lt takes approximately 12-1/2 minutes to locate a satellite and collect
an Almanac. If the signal is interrupted during Sky Search, however,
the unit requires more time to locate a satellite and collect an Almanac.
We recommend that you collect an Almanac before getting under way.
CONNECTING TO AN EXTERNAL DEVICE (NMEA)
The NAV 5000 can interface with various autopilots, plotters, sounders,
and radars through its National Marine Electronics Association (NMEA)
interface. The NAV 5000 supports NMEA standards 0180 and 0183.
The jack on the side of the NAV 5000 provides a connection for both
external power and for NMEA support. The optional Power/NMEA Data
Cable has three receptacles on one end. One receptacle is for the
5-pin AC adapter. Another is an RCA jack for the old-style power
adapters. The third receptacle is to connect to the NMEA device of
your choice. (See illustration on page 2-4.)
NMEA Pin Positlons
To connect the NAV 5000 to NMEA 0180 or 0183 devices you will
have to purchase a 9-pin connector (male DB-9) to mate with the
Power/NMEA Data Cable. They are readily available at any electronics
or marine electronics store. The wires should be soldered into the pins
shown on page 2-14.
