keyword=Mux status : not operational
I tried the Mux ( multiplexer ) for about 1 hour with beam which allows to send data from the calorimeter trigger to the proton array VME crate in order to select only the blocks of the proton array corresponding to the incident photon. We tested it yesterday without beam and it seems to operate correctly. Howewer with beam multiplicity and randomness of the events made the read out list to crash pretty quickly. I guess it is a matter of timing and synchronization between the two crates but for now usage in production is impossible.
