Diagram: Commissioning protocol / false POSI Pulse generated through noise and
threshold set too low
For this example, the thresholds are set to 100 units. The bit
TRANS_IN_FIELD
is
permanently set. After a successful transponder decoding, initially a correct
POSI
Pulse
is generated. However, as the software does not realize that the transponder
leaves the antenna field, each zero crossing of the difference voltage (not shown in
the diagram) will generate another
POSI Pulse
.
