Configurator Passwords
5−19 VM 3000 Installation and Operating Manual
When the level of a panel is raised only temporarily, then re−entry of a password will be required for special commands such
as protect* and lock,* and for front−panel definition of overrides.* It may also be required for executing an Input Sequence.*
For example, Operator Dave can protect the feed to VTR1 (Figure 5−13). No other panel, regardless of password level, could
then be used to change the source:

A more rigorous form of protection is lock, where the output must be deliberately unlocked before changing the source for
a particular destination (Figure 5−14). Only the panel used to lock the output could unlock the output.
