When the Wave Sensor is connected to AiCaP, a list of other
available sensors connected to the SmartGuard/SeaGuard
Datalogger is shown. This makes it possible to get a correct
heading input from another sensor through the datalogger

Heading
Parameter Id
ENUM 1
A list of all available Heading parameters with Deg.M as unit is
shown in the dropdown menu. Also other directions like for
example Current direction from Doppler sensors is shown if
connected to the same logger. Make sure that the correct heading
parameter is selected. Only in AiCaP mode.

Correction
BOOL 1
Enables the use of AiCaP external compass correction for wave
direction calculation. Only in AiCaP mode.
Processing Time
Output
ENUM 1
Configuration of Processing Time Output Off, Storage,
Storage. This is an advanced system output which can be
enabled to give more information when testing the operation of the
sensor. This is the time used for processing all the data from the
last wave integration time. Default is ‘Off’.

FE State
Parameters
Output
ENUM 1
Configuration of FE State Output: Off, Storage, Storage
Two output parameters, FE State and FE Notifications are
controlled by this setting. Default set to Off. The output FE State
parameter is 0 if everything is ok. The FE Notifications parameter
gives information about the last communications with the
coprocessor.
HW State
Parameter output
ENUM 1
Configuration of HW State Output: Off, Storage, Storage
This is an advanced system setting which can be enabled to give
more information about the internal electronic hardware. The output
is 0 if everything is ok. Default set to Off.

1)
Magnetic declination (variation) is the angle between the magnetic north and the true north. This angle varies depending on the
position on the Earth’s surface and also varies over time. Declination is positive when magnetic north is east of true north and
negative when it is to the west (input angle value ±180°). Magnetic declination at the deployment location can be found for i.e. on
http://www.ngdc.noaa.gov/geomag-web/
2)
A generic NMEA compass can be selected. This generic NMEA compass has to be pre-configured; it cannot be configured
through the Motus Wave Sensor. The baud rate of this NMEA compass has to be set to 4800.
3)
The “on” time of the external compass is controlled by the Warm-up Time, the Compass Sample Average Number and the
Compass Sampling Frequency. The on/off duty cycle is also dependent on the Compass Sampling Interval which gives the time
between each start (power on) of the external compass.
4)
The Motus Wave Sensor is also shown in this list. Make sure that an external sensor is selected and not the Wave Sensor itself.
