C TTC machine interface ( TTCmi ) User Manual

The RD12 TTCmi provides a standard interface between the LHC machine timing which is broadcast from the Prevessin Control Room (PCR) and the TTC distribution systems of the individual LHC experiments. The TTCmi consists of a minicrate (see Fig. 1) containing a number of modules which are configured to suit the requirements of the TTC system of the LHC experiment. The modules are interconnected by Lemo cables on the front panel.
