Enter in the field Sensor address the address of the sensor and confirm the
dialogue. The following symbols represent the valid address range of the
SDI 12 protocol: 0-9, A-Z, a-z
New SDI-12 sensors are usually configured for the address 0
by default. Note that a sensor connection is not possible if fur-
ther sensors of the same address are connected. In this case,
disconnect the sensors of the same address. Now connect one
of the sensors individually and change the sensor’s address
using the following setting. Repeat this step until all sensors
have been connected.
Assigning new sensor address
Take the following steps to change the address of a sensor:
1. Enter the current sensor address in the Sensor address field
2. Check the
Assign new address
box
3. Enter the new address to be assigned in the field following Assign new
address
4. Confirm the dialogue
The sensor address is changed automatically and entered in the Sensor
address field of the dialogue.
Note that the address of a sensor is not
changed if
the address is already taken by another
sensor.
The sensor cannot change its address.
Sensor information:
Identification details are queried automatically after creating a sensor.
Sensors must provide their SDI-12 version, manufacturer and precise des-
ignation (sensor model and sensor version). Optionally, a sensor may also
provide a serial number. But this field may also contain other information.
