The CLEO II gating system uses a subset of the timing modules developed to operate the storage ring. Different gates are generated for the various detector types and fanned-out to the crates. The gate widths and placement relative to beam crossing time are software controllable. An event trigger signal is also fanned-out to the crates to initiate the transfer of data to the raw data buffers. The data acquisition system (DAQ90) receives a copy of this signal so that it can check for the completion of the event read-in. On completion, DAQ90 sends a signal to the trigger system to re-enable it. The CsI electronics have an additional fast clear signal to reset the input integrators after a successful level 1 but a failed level 2.
