Readout system for CMS RPC Muon Trigger

This paper presents readout for RPC based muon trigger system, part of CMS experiment on LHC collider at CERN (Geneva). All RPC data used to perform trigger algorithm are collected on RPC trigger boards of and send to general CMS data acquisition system. Zero suppression used to transfer data from detector to control room is used to decrease the amount the links and data to be stored.
