The Computer Automated Measurement And Control system is a modular instrumentation and digital interface system defined as a standardized instrumentation system. It features a fully specified data highway together with modular functional units that are completely compatible and that are available from diverse sources. The CAMAC system is used at almost every nuclear physics research laboratory and many industrial sites, primarily for data acquisition but also for remotely programmable trigger & logic applications. Its function is to provide a scheme allowing a wide range of modular instruments to be interfaced to a standardized backplane called a DATAWAY, which is interfaced with a computer. The DATAWAY provides module power & address, control & data bases, and the lines include digital data transfer, strobe signal, addressing & control lines. CAMAC-related software is for Linux systems.
