19.2.3 Feedback Arbitration
The Feedback Arbiter element is similar to the
operation and offers a force input to allow the operator to override an existing assignment. A typical application
would be to create a telephone hybrid selector.
For arbitration applications, such as a transmitter selector, where you need more protection, use the
Arbiter
element. For selector applications which require signalisation but not arbitration – for example, a
transmitter selector within the studio, use the
This element controls the logic of the selector only and not the audio crosspoints.
Up to 16 input signals can be defined, each with its own Enable and Active output. The Feedback Arbiter allows
only one of the 16 outputs to be active at any one time. If an output is active, then a different output can ONLY be
activated by triggering both the Force Enable and Input x control signals - for example, if MF Keys are used for
the control signals, then the operator needs to press both Force Enable plus the Input x MF Key to change the
active output. The Enabled and Active control outputs can be used to signal the state of the arbiter by
illuminating MF Keys.
The following parameters are configured from the 'Tree Definition':
Feedback Arbiter
X – Input
Force enable
The control outputs appear under "Logic -> <GroupName> -> Feedback Arbiter" in the 'Tree Selection' window:
None active
x Active
x Enabled
X Force Enabled

Enable Func
Reference name for the element.
Assigns the MF Key (or control input) which will activate the corresponding output if no
other output is True.
Assigns the MF Key (or control input) which will force the corresponding output to active
and set all other outputs to False.
Note that both the Force enable and X - Input control signals must be true to change the
active output.
True if all inputs are False.
True if the corresponding input is True.
True if either all inputs are False or the corresponding Force enable is True.
True if the corresponding Force enable is True.
