If several PADA 5100 are cascaded, at the "downstream" cassette (cassette 6
of the example) the station filter (page 29)
must be set to " cascaded ".
Cascading, for example, is used to combine many transport streams each
containing one service to one transport stream.
Example:
"upstream" "downstream"

At setting "cascaded" the assignment of the SIDs is done "statically" (a defined
output SID will be assigned to a defined input SID), so that the SIDs of the serv-
ices at the output of the "downstream" cassette (6) will not change, if the input
signal of one input of the "upstream" cassettes (1…5) is discontinued.
"Static" SID assignment at setting "cascaded"
(for cassette 6 of the example) :
