If we set the mask to a specific bit to 0 or 1, it means that we expect the fixed value in the block (see eg. PI in Block1). If
even one or more of these masks do not match after T Validation Time, an alarm is generated.
If you specify an X for a bit gen
eric, it means that this bit it’s masked and its value is not considered.
Finally, if you specify a V for a bit, we expect that, in the time specified by the timeout, there has been a change of state .
The length of the mask must be 16 characters. If the length is less will not be accepted if the items are cut higher than
16.
It’s possible to associated with one or more filters to a specific channel, simply by associating the index of the channel to
the Channel Ref required. For example, here the filters tuned to the channel (the no. 2) are the n. 4 and n. 7:
7
You can then bind up to 32 filters to a specific channel, or distribute it freely.
IMPORTANT NOTE
In the following examples the ChanRef = 4 because the tuned station is in this specific case on channel 4.
Where it is different, this has to be changed congruently.
In all the examples that follow for generality do not check a specific PI, clearly programming the block 1 for a specific PI,
the filter also considers the IP than simply the service.
