Aux Buses
Aux Bus Overview
The Aux GPI Override setting data is part of the User Config data, and may be saved to and
loaded from the User Config file the saved file will be displayed in the User Config file Enables
list called Aux Override.
The above menu displays a scrollable table of the override setting for each of the GPIs available.
The controls allow the user to edit each of the following settings for any of the GPIs.
Aux Override - this displays the state of aux override, enabled for the specific GPI (enable On
or Off)
GPI - this is the GPI that triggers the override
GPI State - the state of the GPI at which the override function will be active (High or Low)
Aux Bus - the aux bus that the GPI will override
Crosspoint - the crosspoint that the selected Aux Bus will be set to during the override.
If the Aux Override value is set to Off then the GPI State, Aux Bus and Crosspoint setting are
greyed out. The state of Aux GPI overrides is indicated in a column to the right of the
Crosspoint column, shown in the menu below. If aux override is enabled for the specific aux
bus, then a Green square is displayed. If an override is active on the specific Aux Bus, then an
Orange square is displayed.
Overview of Aux Override Active States
When an Aux GPI Override is activated by the external equipment controlling the GPI state, the
crosspoint of the selected aux bus is changed to the “override crosspoint” state. When the GPI
is deactivated the crosspoint of the selected Aux Bus returns to its original state.
If there is more than one override set to act on the Grass Valleye aux bus, and one of those
overrides is activated whilst another is already active then, the previous override will be
deactivated and the new override will take over. When the last override to be activated is
released then the aux bus will revert to its previous crosspoint state.
If the Crosspoint setting is changed whilst an override is active, then the original override will
drop out and the Aux Bus will go to the new crosspoint setting.
If the Override Crosspoint setting is changed whist the override is active, the crosspoint on the
overridden Aux Bus will change to the new value. When the override is deactivated the aux bus
will revert to its previous crosspoint setting.
