It is easy to see that if the logical levels in the Jupiter system consist of small routers with few outputs per logical level, more
of these levels can be controlled by a single VM 3000. However, if the Jupiter system consists of larger routers, fewer of these
levels can be controlled by a single VM 3000, and the system’s router control must be “broken up,” or distributed among
multiple VM 3000s.
In this worst−case scenario, all Saturn Internal levels may be ignored. These levels are controlled directly by the Saturn Pro-
cessors, and not by VM 3000 boards.
Versions of Jupiter prior to 5.1.0 will not handle edit sets which have more than 64 levels. Should you attempt to edit such
a set, the Jupiter Configurator (editor) will detect the error in the Switcher Description table and will not run correctly. Another
symptom is that the Configurator will not exit properly. (If you mistakenly do edit a set with more than 64 levels with a pre
5.1.0 version of Jupiter, terminate the Configurator, delete the invalid set from the YourJupiterDirectory\Config directory,
delete the YourJupiterDirectory\Config\ics_conf file, and re−execute the Configurator.)
CP 38xx Control Panel
If you intend to control more than 32 levels from a CP 3830P or more than 64 levels from other CP 38xx panels, a control
panel firmware upgrade will need to be ordered from the factory.
