To incorporate an external detector in the S800 trigger logic, the same busy and end-of-event signals are required from its data acquisition system. This is to ensure that no live trigger signal is generated when any of the partners is busy or still processing an event. The 5 signals necessary between the S800 trigger and an external data acquisition system are the following: | To incorporate an external detector in the S800 trigger logic, the same busy and end-of-event signals are required from its data acquisition system.
