Figure 9
Diagram: commissioning protocol / disturbed decoding (but still functional)
In the following diagram it is shown how a false set
Threshold for Decoding
or
Threshold for Positioning
can cause erroneous
POSI pulses
.
Figure 10
Diagram: commissioning protocol /POSI-Pulse triggered by noise & too high
Threshold
In this example the thresholds are set to 100 samples. The bit
TRANS_IN_FIELD
is set
constantly. After a successful decoding a correct
POSI pulse
is triggered. As the
software does not know, that the antenna field is left then, each further zero crossing
of the difference sum generates a new
POSI pulse
.
Disturbed decoding (function still available)
POSI-Pulse triggered by noise & too high threshold
