19.2.3 Feedback Arbitration
The
Feedback Arbiter
element is similar to the
. It is a one out of sixteen switch but is simpler in
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
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
Reference name for the element.
X – Input
Assigns the MF Key (or control input) which will activate the corresponding output if no
other output is True.
Force enable
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.
The control outputs appear under “Logic -> <GroupName> -> Feedback Arbiter” in the 'Tree Selection' window:
None active
True if all inputs are False.
x Active
True if the corresponding input is True.
x Enabled
True if either all inputs are False or the corresponding
Force enable
is True.
X Force Enabled
True if the corresponding
Force enable
is True.
