4.1.5.6 SDI 12
The SDI 12 type is used by Alpha-Log for the acquisition of sensors with SDI 12 output.
It is associated with the COM5 port (§Fig. 2) of the data logger.
Under further development.
4.1.5.7 Atmospheric pressure
The Atmospheric Pressure type is used by Alpha-Log to acquire the pressure value by the sensor mounted
inside. In the factory setup this measurement is preset.
4.1.5.8 Thermo-hygrometer SNS
The Termo-hygrometer SNS type is used by Alpha-Log for the acquisition of the LSI LASTEM PRTHA0700
sensor.
It is associated with the I
2
C input(2) of the data logger.
This type of input does not require the setting of other parameters.
4.1.5.9 Boschung
The Boshung type is used by Alpha-Log for the acquisition of LSI LASTEM sensors with Boschung protocol.
It is associated with the COM2(4) and COM3 ports (§Fig. 2) of the data logger.
The parameters relating to the Boschung type are the following:
➢ Communication port: it is the serial port where the sensor is connected.
➢ Speed: it is the communication speed of the serial port. Default value 1200 bps.
➢ Parity: it is the parity used in communication with the sensor. Default value None.
➢ Stop bits: it is a parameter used in communication with the sensor. Default value 1.
➢ Timeout: it is the protocol wait time after sending a request. Default value is 5 ms.
➢ Intra-character timeout: it is the intra-character delay used in the data request message sent to the
sensor. Default value 0.
➢ Retries: it is the number of attempts to send the request after a timeout without reply. Default value
2.
