7.2.8 Digital output commands
Both optocoupler-outputs (see CH.
5.3.3
) can be configured independently of each other with the
commands “D1” or “D2”. Following information can be given out:
•
Precipitation amount (output of impulses, resolution 0.1, 0.01 or 0.005mm)
•
State information (output open/closed or frequencies)
•
Precipitation type (frequencies)
A changing of the frequency and the state or the possible output of precipitation amount is done
always when the internal clock of the sensor changes a minute. When using the output of the
amount it should be respected that because of the preset resolution the possible residual amount
can be given out in the future. We recommend therefore to use a preferably highest possible
resolution (e.g. 0.005mm), if the amount of single precipitation events is of interest.
Additional hints:
•
The parameters 0 and 16 are for testing of the wiring and the external record electronic.
•
Solid precipitation: s
now grains
, snow, soft hail/ice grains, hail
•
Liquid precipitation: all other precipitation types (drizzle and/or rain, sleet [=rain and snow]
and unknown precipitation
