In Polled Mode the sensor uses the Polled Pingrate setting. In non-polled operation the sensor uses the Interval
1)
property and the Ping Number property to calculate the ping rate. This is an enumerated value. The selectable ping rate
is shown when sending a Help command to the sensor or in the drop-down list shown in Real-Time Collector. The input
has to be written as shown with Hz as unit. This value was not enumerated on software versions prior to version 8.1.27.
On earlier software versions the values where restricted to the same ping rates (written without unit) but not shown as
an enumerated list when sending a Help command or changing the setting in Real-Time Collector.
The fixed heading value here is the angle in degrees between north direction and transducer 1 (clockwise) – Refer
2)
Figure 6-2. When viewing the sensor from the front (label side) transducer 1 is to the left on the rear side. If for example
transducer 1 is 118° clockwise from north, the fixed heading should be set to 118°. The fixed heading is a value
between 0 and 360 (0 and 360 is the same point).
Even though the user should configure the sensor as upward or downward looking, the sensor detects automatically
3)
the orientation when it is in operation. It uses this orientation to calculate the correct North, East and Vertical speeds
and also for the calculation of correct compass heading, pitch and roll. If the sensor detects that it is upside down
(while configured upward looking and surface referred), the surface cell parameters are set to zero and the parameter
status codes returns a "not valid error". If one of the columns is set to surface reference, the column is forced to be
instrument referred. If the sensor is configured to be upside down but measures that it is orientated upward looking, both
surface cell and surface reference will work if enabled. The 'record status' (in the output data) will indicate in the first bit
Enables output of the measured input voltage internally in the sensor.
This is a way to see if the input supply voltage starts dropping.
1
'Off' or 'Output' (in AiCaP Off, Storage or Output+Storage).
Enables output of the measured input current to the sensor. This can
indicate if something is wrong in the internal electronics if it suddenly
1
starts to rise.
5)
'Off' or 'Output' (in AiCaP Off, Storage or Output+Storage).
Outputs the value measured by the air detect circuit. This is a circuit
which detects if the sensor is in air or water.
1
'Off' or 'Output' (in AiCaP Off, Storage or Output+Storage).
Enables output of the speed of sound. If Derived Sound Speed is
enabled, this is the value calculated from the other input settings. (or
1
sensors in AiCaP). If not, it outputs the sound speed setting.
'Off' or 'Output' (in AiCaP Off, Storage or Output+Storage).
Enables depth output. This is the calculated depth, i.e. calculated from
other settings (or sensors in AiCaP).
1
'Off' or 'Output' (in AiCaP Off, Storage or Output+Storage).
Enables salinity output. In AiCaP the sensor can get input from a
Conductivity, Temperature and Pressure Sensor. This enables the
sensor to calculate the salinity. If no sensors are present, it outputs the
1
salinity setting.
6)5)
'Off' or 'Output' (in AiCaP Off, Storage or Output+Storage).
Enables output of calculated density. This is either based on sensor
input (in AiCaP) or fixed settings.
