GPO CONFIGURATION

The CEM module has two general purpose outputs available on the DB-9 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 also has the ability
to configure which faults the CEM will assert onto the frame status system. The GPO configuration menu
contains the controls used to configure the GPOs. Sections 7.9.1 to 7.9.3 give detailed information about
each of the menu items.

Controls whether the general-purpose output is active high or low.
Controls what events will trigger the general-purpose output.
Controls what events 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 what condition 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, you can select the condition for the card to cause the line to go active.
Also included on the frame status signal is 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 J3 (located near the
card extractor) must also be set to the On position. See section 9.2
The Red Local Fault LED will be On when the global status line is active
regardless of the position of jumper J3.
