Protected Paths
be re-arranged in a symmetrical pattern in order to simplify Protected path
configuration.
The numbers shown here correspond to the connector numbers used
during router configuration (but not, in most cases, to the actual silk screen
number on the rear panel itself since the silk screen numbers only run from
“1” to “32.”)
In Jupiter-controlled systems, the Name column in these tables corre-
sponds to the “logical input/output name.” The entries in the number
column correspond to the “physical” input/output number.
The next example applies to existing systems where re-arrangement of
cables in a sequential pattern is not practical or desirable:
Notice that in all cases the primary path I/O numbers are always in the 1-
256 range while the secondary path I/O numbers are always in the 257-512
range.
