August 2020 – TD 316 OPERATING MANUAL – Motus Wave Sensor 5729
1.7.4 User Maintenance
This group contains sensor settings that normally are not altered by the user. To access most of these properties you
need to send passkey(1000) or with Real-Time Collector use password: 1000. These properties are used to configure
serial port settings, communication to and from sensor in addition to some sensor settings.

Baudrate
ENUM 1
RS232 baudrate: 4800, 9600, 57600, or 115200. Default baudrate
is 115200. The baudrate affects the minimum available Interval
setting.
Flow Control
ENUM 1
RS-232 flow control: ‘None’ or ‘Xon/Xoff’. Default setting is
Xon/Xoff’. To remove the “disturbance” on the receiver, select
None. Be aware that this may also lead to missing characters when
sending commands to the sensor.
Enable Comm
Indicator
ENUM 1
Enable communication sleep (’%’) and communication ready (‘!’)
indicators. After the last communication with the sensor, it normally
outputs a ‘%’ when the
Comm Timeout
time is over. When a
character is sent to the sensor, it outputs a ‘!’ to indicate that it is
ready to communicate.
Comm TimeOut
BOOL 1
Time communication is active (Always On, 10 s, 20 s, 30 s, 1min, 2
min, 5 min, 10 min). A short time means that the sensor is going to
sleep faster after a communication input.
Enable Off-centre
Correction
BOOL 1
Enables the correction of displacement errors due to a sensor
located off the buoys rotational origin. The errors in the vertical
displacement will have impact on the calculated significant wave
height.
Off-centre XYZ
(m)
Float
3
The sensors installation position (X,Y,Z) relative to the rotation
origin of the buoy. Based on this position and the sensors
orientation sampled at 4Hz, the added displacement for the X,Y
and Z component are coherently subtracted to the IMU based
displacement. By activating this function the wave height and the
wave direction are more precisely calculated for a wave sensor
installed off the buoys rotational origin.
