NMEA INPUT 1
Configures the NMEA input 1.
MESSAGES NMEA INP. (Input) 1
Selects the NMEA sentences to receive.
Settings: HDT
Enables the input to receive true heading data from the
$--HDT sentence.
Selecting this option lets the system ignore heading data
from the satellite PCB in favour of the external data.
HDT (true heading) may be read from any source which
meets or exceeds the performance specifications of the sat-
ellite PCB’s heading output. Using external heading from a
gyrocompass will improve the accuracy at which the ves-
sel’s velocity over ground is resolved into the longitudinal
and transverse ground speeds.
Note If HDT is configured at NMEA INPUT 1 and NMEA INPUT 2,
the HDT setting at NMEA INPUT 2 is automatically deactivated.
ROT
Enables the input to receive rate of turn data from the
$--ROT sentence.
Selecting this option lets the system ignore rate of turn data
from the satellite PCB in favour of the external data.
ROT (rate of turn) may be read from any source which meets
or exceeds the performance specifications of the satellite
PCB’s rate outputs.
Note If ROT is configured at NMEA INPUT 1 and NMEA INPUT 2,
the ROT setting at NMEA INPUT 2 is automatically deactivated.
ACK
Remote alert acknowledgement is received through the
$--ACK sentence.
ACN
Remote alert acknowledgement is received through the
$--ACN sentence.
DDC
Dimming commands are read from the $--DDC sentence.
Note If DDC is configured at NMEA INPUT 1 and NMEA INPUT 2,
the DDC setting at NMEA INPUT 2 is automatically deactivated.
PPLAI
Dimming commands are read from the proprietary $PPLAI
sentence.
Note If PPLAI is configured at NMEA INPUT 1 and NMEA INPUT 2,
the PPLAI setting at NMEA INPUT 2 is automatically deactivated.
