User Manual
GPO Setup
This GPO Setup menu is used to tally Crosspoint based, Bus based and User BIT functions.
The default setup state allows the user to tally GPO’s 121 to 256 which are the physical and
internal GPO’s and are comprised of:
GPO 121 to GPO 132 and GPO 133 to GPO 144 are the physical Ref Fin GPO’s, again at the rear
of the mainframe. These GPO’s are system setup dependant; GPO 121 to GPO 132 Ref Fin A,
GPO 133 to GPO 144 Ref Fin B.
GPO 145 to GPO 256 are Internal GPO’s (but the configuration could be GPO 133 to GPO 256 if
only 1 Ref Fin is fitted).
The Internal GPO’s are used to trigger internal function such as Macro’s or any internal function
that can be switched On or Off.
This menu allows the user to trigger a GPO or GPI when for example a crosspoint is setup to
trigger a GPO, or an Aux is setup to trigger a Bus tally.
Touch the attacher below the GPO table and the parameters will change allowing the user to
setup a GPO trigger.
For a crosspoint tally for example, use the GPO Select parameter to the required GPO, use the
Crosspoint parameter to select the crosspoint that will trigger the GPO, and then select the
Crosspoint Tally. In the GPO Enables button area of the menu, press the {GPO} button and
each crosspoint trigger will only trigger a GPO, or touch the {Xpt Now} button, then when the
selected crosspoint button (as shown in the menu above) is pressed the GPO will be triggered.
Note: Touch the popup selector (blue square) in the Crosspoint parameter
and a greater selection of GPO trigger options will be displayed.
