Lock
A property placed on a destination that prevents all panels and ports from taking a switch on that
destination, including the panel or port that locked it.
Locks may be cleared by any panel or port that has the same requester code and lock priority as
the panel that locked the destination, that has a higher lock priority, or that has a lock priority of 0
(zero).
See also: Lock Priority, Protect.
Lock Priority
A property of panels and ports which allows them to be grouped with other panels or ports for the
purpose of establishing lock and protect authority.
The lower the lock priority number, the higher the priority. Panel lock priorities not explicitly
defined automatically default to “0” which gives absolute authority to clear any lock or protect on
the system.

Logical Input
One or more physical inputs which are switched together as a group.
Logical inputs and outputs are switched level-by-level. Since each level may have more than one
component, switching a single logical input or output may involve switching more than one
physical input or output.
For example, a RGB input signal represents three physical inputs because it is connected to three
input connectors on the routing switcher. However, since all three components (R, G, and B) are
switched together as a level, it is a single logical input.
Logical inputs are numbered sequentially, level-by-level, beginning with 1. Input numbers are
assigned in the same order as the physical inputs to the component(s) of the level. Since a routing
switcher may be configured to have more than one level, it may have more than one logical input
designated as number 1. However, within each level, every logical input will have a unique
number. Logical outputs are numbered in the same manner. Logical input/output numbering is
handled automatically by Win3500Plus as components are configured.
