Chapter 4 – Commissioning
In the following diagrams examples for registered data are shown:
Figure 6
Diagram: commissioning protocol / low interference; sum voltage over track
In the diagram the sum voltage over the track is shown. The noise (interference) level is lo-
cated at 50 samples, the signal at 950. The decoding of the transponder is faultless, as also
shown in the following picture.
Figure 7
Diagram: commissioning protocol / undisturbed decoding of the transponder
When crossing a transponder the sum voltage rises. After exceeding the
Threshold for De-
coding
the bit
TRANS_IN_FIELD
is set. After 4 x 8 ms ( = four data points) is transponder
code is decoded. The duration depends on the settings made under
Number of Equal Codes
in the submenu
Time & Code
. In this example
2
is chosen, that means that the input code
is compared with the two precedent codes.
