Before refitting the cover lid, the sensor unit must be configured in accordance
with the setup instructions provided in the following sections.
5.3.3 Set Address Switch (SW100)
Each sensor must have a unique address on the network. The address is set by
means of a DIP switch (SW100).
Only switch positions 1 through 6 are used, giving valid address settings from 1
to 64. The illustration below shows address 5. The address switch uses binary
coding to calculate the required address.
Example: to set the sensor to address number 5: set switch 1 (binary 1) ON and
switch 3 (binary 4) ON (4 + 1 = 5).
5.3.4 Set Sensor Comms Mode (SW101)
The sensor offers two communications (comms) modes: ASCII and RTU. The
Comms mode is set by means of a DIP switch (SW101).
