1.7.3 System Configuration
This group is used to control the sensor via properties for configuring communication with logger, sensor setup and
parameter enabling and controlling the output from sensor. Some of the properties are only visible depending on the
mode selected or if the function is enabled or not. These properties will either be grey or not visible at all. The wave
properties are only visible if a license key is set.

Mode
ENUM 1
Sets the sensor operation mode (AiCaP, Smart Sensor Terminal and
AADI Real-Time). AiCaP is not available on the R-version (5400R) of
the sensor. Smart Sensor Terminal is an ASCII output when AADI Real-
Time is XML output.
SC

Low
Enable Sleep BOOL 1
Enables sleep mode in Smart Sensor Terminal and AADI Real-Time
operation to save power (In AiCaP the sensor always tries to sleep
when not busy).
Enable Polled
Mode
BOOL 1
Enables polled mode in Smart Sensor Terminal Mode. When set to ‘no’
(non-polled operation) the sensor will sample at the interval given by the
Interval property. When set to ‘yes’ the sensor will start to do ping
measurements at the selected Polled Pingrate. A Do Sample command
triggers the end calculations and output of data. A Do Output command
can be sent to repeat the output of the last calculated data.
1)
Polled
Pingrate
ENUM 1
Selectable ping rate in Polled mode between 0.1 and 10.0 Hz. The
maximum ping rate is limited by the configuration, i.e. large profile with
many cells gives lower maximum available pingrate.
1)
Default is 1 Hz.
No /
No
Enable Text
BOOL 1
Controls the insertion of descriptive text in Smart Sensor Terminal
mode, i.e. parameter names and units. Can be used to reduce message
size.
No /
Low
Enable
Decimalformat BOOL 1
Controls the use of decimal format in the output string in Smart Sensor
Terminal mode. Default is scientific format (exponential format).
Enable Tilt
Compensation BOOL 1
Tilt compensation is used for correct positioning of the beam cells in
each depth cell. It also compensates the Doppler speed measurements
for variable tilt to calculate correct speed components (North, East and
Vertical). Default enabled.
Enable Fixed
Heading
BOOL 1
Allows the user to deactivate the internal compass and set a fixed
heading value. This can be used if for example the sensor is standing
on a fixed platform where the earth magnetic field is disturbed.
