Auxiliarity modules for the SUMMA serial highway

A modulus of the SK-137 sorter-coder of demands and a modulus of the U-port adapter designed for expansion of opportunities and application of the SUMMA serial highway are described. The SK-137 modulus exercises sorting and priority coding of service request. Twelve commands of the frame channel implemented by the sorter-coder are given. The SK-137 modulus may be applied in systems for experimental data collection and processing as well as in automated systems of radiation control. The AM-190 adapter modulus ensures operability of the SUMMA serial highway on an auxiliary communication channel under the noise conditions at large distances between the frames. The modulator exercises data signal multiplexing and produces a phase-modulated signal coming to the linear transducer and transformer. The modulus of the adapter is successfully used in the system of interpanel data exchange of the automated systems for beam diagnostics and extraction as well as the radiation control system
