NMEA INTERFACING WITH GPS PLUS
The two sockets on the rear case of the GPSPlus display
are NMEA input/output connectors for position fixing
instruments, radar sets, autopilots and other devices
requiring NMEA interfacing. The connectors allow bi-
directional data communication using the NMEA 0183 v1.5
protocol. This allows input of positional data (latitude and
longitude) and other position fixer information (e.g. satellite
data) into the GPSPlus display unit for displaying, and
output of control sentences (including waypoint data) to a
position fixer.
In a standard GPSPlus system the GPSPlus
antenna/receiver unit uses the top connector, leaving the
other for connection to a secondary NMEA device (e.g. a
GPS, Loran-C or Decca receiver).
GPS Plus RECEIVER SOCKETS
NMEA input/output to the position fixer receiver has
