Logical Inputs/Outputs
Inputs and outputs defined on a level of control basis. Each level of
control specifies a number of logical inputs and outputs that exist for that
level. Logical inputs/outputs are the lowest level at which a user can
specify a switch. These are the inputs and outputs that are assigned to
sources and destinations. A logical input or output may consist of physical
inputs/outputs taken from one or more components. (e.g. a NTSC
composite input consists of a single physical matrix input while a RGB
input consists of physical inputs taken from the R, G, and B components.)
Matrix Breakup
The division of a physical matrix into one or more components. Done in
software, matrix breakup allows complex signal types to reside within a
single physical matrix. For example, a video matrix is often broken into R,
G, and B components.
Panel
A user interface enclosed in a box (usually rack mount) with a combination
of alphanumeric displays, push-buttons and LEDs. Panels allow a user to
take switches on the routing system, perform actions such as lock and
protect, and obtain status of the state of the routing switch system. On the
3300, panels communicate to the controller through an RS-485 twisted
pair interface.
