Trigger Distribution
As described in § 3.4, the OR of all the enabled trigger sources, synchronized with the internal
clock, becomes the common trigger of the board that is fed in parallel to all channels,
consequently provoking the capture of an event. By default, only the Software Trigger and the
External Trigger participate in the common acquisition trigger (refer to the red path on top of Fig.
3.10).
A Trigger Out signal is also generated on the relevant front panel GPO connector (NIM or TTL),
and allows to extend the trigger signal to other boards. Thanks to its configurability (see Fig.
3.10), GPO can propagate out:
- the OR of all the enabled trigger sources (only the Software Trigger is provided by default, as
in the red path of Fig. 3.10);
- the OR, AND or MAJORITY exclusively of the channel trigger requests

The registers involved in the GPO programming are:
- Register address 0x8110;
- Register address 0x811C.
