Venus DM 400/400A
L−4 CM 4000 Installation and Operating Manual
As an alternative scheme, it is possible to use the same entry in the “Switcher” column (for example, “MAINROUT”) for
all levels, including the data levels (Figure L−4). In this case, the Switcher Input and Switcher Output tables will have columns
for all switcher levels.
Figure L−4.
Name chosen for data router must sort alphabetically before names used
for other switchers (e.g., “M” comes in the alphabet before “O.”

Note: A limitation in the present software requires that the entries in the “Switcher” column for the data router
levels must be the same as or come alphabetically before all other names used in the Switcher column. In Figure
L−4 this rule is satisfied because the entry “MAINROUT” in rows 5 and 6 is the same as the entry in rows 1 through
4, and because the letter “M” in “MAINROUT” comes alphabetically before the letter “O” in “OLDROUT.” This
does not mean that the entries must be in alphabetical order within the table itself.
For a discussion of the ”DM 400 Off Time” entry, see page 5−47.
