Description of user configurable properties
The
Node Description
property is a user defined text that describes the sensor or the location of the sensor.
The
Mode
property is used to set the sensor operation mode of the sensor. Set the
mode
property to
AiCaP, Smart
Sensor Terminal, AADI Real-Time, Smart Sensor Terminal FW2
to enable the different sensor operations.
Note! The
mode
Smart Sensor Terminal FW2
brings the sensor into an operation mode with output string that is compatible
with AADI framework 2
.
‘
AiCaP
’
sensors will be set to RS-232 operation if configured to RS-422 communication
interface. An R-sensor will be set to RS-422 operation if configured to AiCaP or RS-232 communication interface.
Set the
Enable Text
to
Yes
for the sensor to output a detailed text string (including the output parameter name and
engineering unit names) with the measurements, or
No
to output the measured values without the descriptive text.
Set the
Enable Decimalformat
to
Yes
to output the measured values in decimal format. Set the property to
No
(default) to output the values in exponential format (higher resolution in the output parameter value). Example of
decimal format: the presented value is e.g.
0.0025
. Example of exponential format: the presented value is e.g.
2.500000E-03
.
Set the
Enable Sleep
to
Yes
(default) for the sensor to go to sleep between recordings, or
No
for the sensor to stay
continuously switched
on
between recordings (consumes more power).
Note! After receiving input at the RS-232 or RS-422 interface or as
Polled
input,
Comm TimeOut
will decide when the
sensor is allowed to re-enter sleep mode. In
AiCaP
mode the sensor will always enter sleep mode between
recordings/calculations. Setting
No
is not recommended for battery operation as the current drain will rise by up to
9mA continuous. The accuracy of the temperature readings will also be reduced and may not meet published
accuracy specification with this setting due to internal self-heating.
The
Interval
property describes the output interval in seconds (stand-alone sensor). The value must be a float
between 1 and 15300. The sensor provides a set of measured/calculated data for every output interval. When
configured to
non-polled
mode the sensor can be used in systems with one-way communication. In
Polled
operation
the sensor will present data only on request (the internal interval timer is disabled). In
AiCaP
mode the interval is
controlled by the SeaGuard or SmartGuard instrument (minimum 2 seconds).
Note! For 5218/5218R Wave and Tide sensor with pressure series and/or spectrum enabled, the interval will
automatically be extended to 1 min if the interval setting is less than 60 seconds.
The
Vertical Position
property is a user defined value that describes the sensor installation depth. The information is
not used in calculation of parameters.
Set the
Enable Temperature
and
Enable Rawdata
to
Yes
to include these parameters in the output string. The raw
data readings are values directly from the 24 bit ADC.
The
Comm TimeOut
property controls how long the sensor will wait for the next command before it shuts down the
transceiver (indicated by the communication sleep indicator ‘
%
’
). In this time period the sensor is not allowed to
enter communication sleep. If set to
Always On
, the sensor will not need a wakeup character and is always ready to
read incoming commands. This setting will not allow the sensor to enter communication sleep, and is not
recommended for battery operation. In
AiCaP
mode the setting is overridden to 1 minute when configured using the
RS232 line.
