The VME-based data acquisition system designed for physics experiments involving measurements of several hundreds of parameters is described. The equipment has been tested in the experiments with the He, He, Ne, and S beams at the ACCULINNA fragment separator () in the energy range of 20-35 MeV/nucleon. The system is composed of the RIO-3 processor module, which is used to read the VME bus, communicate with the CAMAC and FASTBUS crates, and transmit data to the personal computer; the TRIVA-5 master trigger module; standard analog-to-digital, charge-to-digital, and time-to-digital converters from CAEN (V785, V792, and V775 models); and related software. This data acquisition system is faster (by a factor of 10) than a CAMAC-based system and is capable of operating with new types of electronic modules, e.g., with digitizers. [ABSTRACT FROM AUTHOR]
