Group selection (Water temperature input): This parameter
allows you to connect the PI44 to a group of SimNet
instruments. If such a group is not present, the parameter is
unavailable, and fixed to STAND-ALONE. This means that you
can manually select data source from third-party units.
Source (Water temperature input): The PI44 will automatically
read the NMEA inputs to search for available water temperature
sources. If no sources are found, the phrase “(none available)” is
given. If one or more sources are found you may choose
between them. In the example above, the internal echo sounder
transducer is the only source available.
Water temperature offset : This function allows you to enter an
offset value for the temperature sensor.
Water speed input: The PI44 is here configured to receive
water speed information from an external source.
Group selection (Water speed input): This parameter allows
you to connect the PI44 to a group of SimNet instruments. If
such a group is not present, the parameter is unavailable, and
fixed to STAND-ALONE. This means that you can manually
select data source from third-party units.
Source (Water speed input): The PI44 will automatically read
the NMEA inputs to search for available water speed sources. If
no sources are found, the phrase “(none available)” is given. If
one or more sources are found you may choose between them.
In the example above, no sources have been found. To correct
this, you must set up your speed log to provide the current speed
on NMEA format, and connect a serial cable to the PI44
operator station.
LOG speed cal (ibration): The PI44 is preset to receive 19.000
pulses per nautical mile from a paddle wheel speed log.
However, this figure may need to be compensated for known
variances or if an other speed logs is used. The pulse rate is
calculated by the following equation:
(19.000 x Indicated speed) divided by (Actual speed from GPS)
NMEA0183 Ouput : Select any of the telegram formats
provided below, and switch them on or off for output on the
NMEA1 or NMEA2 serial lines. Note that the information can
only be exported if the PI44 can in fact provide the information.
