Three front panel security lockout modes (Executive modes) — If a matrix switcher
is installed in an open area, where operation by unauthorized personnel may be a problem,
either of two security lockout modes can be implemented (the third mode is unlocked).
When a front panel locked mode is enabled, a special button combination or SIS command
is required to unlock the front panel controller and make the front panel fully operational.
I/O grouping — Allows the matrix to be virtually divided into smaller sub-switchers,
making installation and control easier. I/O grouping limits the selection of inputs and outputs
to members of the same group. I/O grouping allows specific outputs, such as those
designated for a specific purpose, to be grouped together.
Power — The matrix switchers’ 100 VAC to 240 VAC, internal power supply(s) provides
worldwide power compatibility.
Primary and redundant power supplies (Matrix sizes 2412 and larger only)—
Includes two internal 100 VAC to 240 VAC, 50/60 Hz, switching power supplies, which
provide worldwide power compatibility.
The power supply circuitry is configured to automatically switch over from the primary
supply to the hot redundant supply in the case of a failure.
The hot redundant power supply means high reliability for the system and no loss of
functionality should the primary supply fail; the redundant power supply immediately
assumes the load.
Power supply status LEDs (Matrix sizes 2412 and larger only)— Front panel LEDs
indicate the status of the primary and redundant power supplies.
