Menu D(e)coding
In this menu some parameters which are important for the decoding can be set.
As the transmission of the codes of trovan™ transponders is only ensured by the sim-
ple parity check, two further strategies were implemented:
1.
The highest four bits can be checked for a default value (0 F) at RW transpon-
ders. This value can be fixed here with
and then must be programmed also
correspondingly into the transponders together with the desired code. When the
value is higher than F the check is switched off.
2.
For RO and RW transponders the number can be chosen between 0 and 15 of
codes to be compared with
. Any received code is immediately put out when
entering 0, at 1 a received code is compared etc. with the previously received
code. Note that due to this method, the at highest possible crossing speed sinks
since the necessary duration of a transmission is now (n+1) x 8 ms.
With
you can decide, from which voltage on the code decoding starts in order to
prevent decoding when the signal is too weak.
You can execute a reference transponder test with
. The result can be found in the
system status word (in the status line E) or by entering
in the main menu (in plain
text).
