Figure 6-27 NMEA out
The NMEA “listeners” must be
connected to either TB6 or TB7.
Figure 6-28 NMEA in
The NMEA “talkers” must be
connected to either TB5 (GPS) or
TB11 (Autopilot and other). The IN
ports are non polarized (colour
independent).
Notes !
1. The NMEA input ports are dedicated, i.e. port no. 1 is for
GPS/Plotter data and port no. 2 for other data. Refer to the
NMEA table on page 56 to identify which signals (GPS_Data
and Nav_Data) and corresponding NMEA sentences that
should be connected to TB5 (port 1).
2. As a rule of thumb, the GPS/Chartplotter should be connected
to TB5 (input) and TB6 (output), whilst the autopilot should
be connected to TB11 (input) and TB7 (output).
3. Please observe the following:
− IS15 will read depth on NMEA provided the IS15 depth
sounder is turned off.
− IS15 will read wind speed and angle on NMEA when
there is no wind transducer connected.
− IS15 will not
read water speed and temperature on NMEA
when there is an IS15 Expander (or IS15 Transceiver) in
the system.
4. The output ports (TB6, TB7) are outputting parallel data and
each port can drive two NMEA “listeners”.
