GPO CONFIGURATION

The AVC module has a general purpose output available on the high-density DB 15 connector which can
be used to signal several conditions to the user. In addition, this output can be configured to be active
high or low. The 7700 frame also has a fault monitoring LED and general-purpose output. The user has
the ability to configure which faults the 7735AVC-LB will assert onto the frame status system. The GPO
configuration menu contains the controls used to configure the GPOs. Sections 7.6.1 to 7.6.3 provide
detailed information regarding each of the menu items.

Controls whether the general-purpose output is active high or low.
Controls the events that will trigger the general-purpose output.
Controls the events that will trigger the Frame Status Fault line and the Fault
Status LED.
This control sets the output level for active state of the general-purpose
output.
NOTE: The output will power up in a high state until the software has had
sufficient time to update the output with the appropriate condition.
This control configures the condition that will cause the general-purpose
output to go to the active state.
The 7700 frame has a global status line that any card can pull active. With
this control, the user can select the condition for the card to cause the line to
go active. Also included on the frame status signal is the card power supply
monitoring. This is derived with hardware and cannot be disabled from the
status signal.
If it is desired to use this feature, the frame status jumper J22 (located near
the card extractor) must also be set to the On position. See section 10.1
The Red Local Fault LED will be On when the global status line is active
regardless of the position of jumper J22.
