Tone sequence parameter for encoder and decoder
Tone duration (encoder)
The duration of the 1st tone (channel 1..4) is defi ned in the
UGA(1..4)-register 244 at the 1st and
2nd digit.
The duration of the other tones (channel 1..4) is adjustable in the
UGA(1..4)-register
244 at the 3rd and 4th digit
. The values can be confi gured in steps of 5ms and are encoded
to their exact specifi cations. Please refer to the section
Tone chart
for the programming of the
different tone durations. The duration of the fi rst tone may differ from the other tones. For example:
tone duration 1st tone = 1000ms and 2nd to 5th tone = 70ms.
Tone duration (decoder)
Certain tolerances have to be allowed when decoding a tone sequence so that unexact tone
telegrams can be decoded reliably.
The minimal duration of each tone of a tone sequence (channel 1..4) is defi ned in the
UGA(1..4)-
register 241 at the 1st and 2nd digit
. The maximum duration of the 1st tone (channel 1..4) is
adjusted in the
UGA(1..4)-register 242 athe 1st and 2nd digit
. The maximum duration of the
other tones (channel 1..4) is adjustable in the
UGA(1..4)-register 242 athe 3rd and 4th digit
. The
values are selectable in steps of 5ms. The tone sequence and the given tolerance determine the
minimum and maximum tone durations. The recommended tolerance is about +/- 25%. Please
also read section
Tone chart
.
Tone sequence
The tone sequence (channel 1..4) is selected in the
UGA(1..4)-register 240 at the 2nd digit
. See
the following chart.
The duration of a tone is not automatically changed when selecting a tone sequence. If, for example,
there is a change from "ZVEI1" to "CCIR" the tone duration has to be newly defi ned. Please also
read the sections
Tone duration (...).
