4.11.5.4 System and Panel Resets
After a red button reset the Supervisor and target panels maintain the mimic/control session.
After a black button reset the Supervisor and target panels mimic/control session is lost.
When a Supervisor Panel is taken off-line from the matrix, the matrix deletes the mimic/control session
and informs the target panel that the session is terminated.
When a Supervisor Panel is brought back on-line it attempts to restore the mimic/control session with
the target panel. If the target panel has become the target for another Supervisor Panel the attempt will
fail.
4.11.6 Configuration Downloads
After a Non-Intrusive or 'Red Reset' configuration download the Supervisor and target panels maintain
the mimic/control session.
4.11.7 Input / Output Level Control
The PD4225 Supervisor Key Panel, with attached PD4203 Level Control Panels, can provide a
combination of input and output level control for the program sources, destinations or other physical
ports. A maximum of 80 separate level controls can be applied to a nominated range of ports. The Level
Control Panels are centred at 0dB and can provide a range of -70dB to +12dB.
It is recommended that the level controls be mapped to a contiguous range of ports, for ease of
operation, and it is also recommended that the program source DAKs are also configured as a
contiguous range. This allows each level control to map physically to the program source Extension
Panel DAK above or below it.
NOTE: The input and output port details that are to be controlled by the PD4225 I/O Level Control
capabilities are factory set on request and can only be modified by Vitec Group Communications.
