LSI Lastem data logger configuration
The DNB146 sensor is configured to work with both analog and digital outputs. Configure the type of sensor
output based on the data logger in use.

The analog inputs available are 4, so it is necessary to exclude a measurement.
4.1
Use of analog outputs
To use the sensor with analog outputs, start the 3DOM program and proceed as follows:
➢
Open the current configuration of the data logger.
➢
Add the
DNB146 An
sensor from the sensor library.
➢
Then, for each measurement:
o
In the
General
tab, if you use multiple sensors of the same type, customize the name of the
measures to distinguish them from each other.
o
In the
Elaborations
tab, choose the desired elaborations.
➢
Save the configuration and send it to the data logger.
4.2
Use of digital output
To use the sensor with analog outputs, start the 3DOM program and proceed as follows:
➢
Open the current configuration of the data logger.
➢
Add the
DNB146 Dig
sensor from the sensor library. If the data logger in use is Alpha-Log, you will
be asked to set the Modbus as input type and the communication parameters of the serial port
where the sensor will be connected.
➢
Then, for each measurement:
o
In the
General
tab, if you use multiple sensors of the same type, customize the name of the
measures to distinguish them from each other.
o
In the
Elaborations
tab, choose the desired elaborations.
➢
If the data logger in use is E-Log, set the Modbus protocol and the communication parameters of
the sensor in the serial line 2 of the data logger.
➢
Save the configuration and send it to the data logger.
