Range
It is very difficult to specify a range due to the influence of various factors. Based on practical
tests, it is possible to provide guideline values. These can be clearly exceeded or fallen
below depending on the actual application:
The range depends on the following:
– Data rate set (default setting: 125 kbps)
– Antenna cable length
– Antenna used
