The Modbus interface can be used to program an alternative output
variable
instead of the standard display.
In this case, the first line indicates the value and index
while the second line indicates the corresponding unit statically .
The index identifies the display type:
Index 1 = CO
2
content in ppm
Index 2 = air quality (VOC) in %
Index 3 = temperature in °C
Index 4 = relative humidity in % r.H.
By default, the display indicates the following measurements
with the corresponding units cyclically and consecutively:
CO
2
content in ppm, air quality (VOC) in %,
temperature in °C, relative humidity in % r.H.
Backlighting is provided for improved legibility.
The Modbus interface allows the display to be
individually configured, both in the 7 and 14 segment range
and in the dot-matrix range.
