scope:

This standard is intended to define the signals, timing and logical organization of the connections from crate controllers and branch drivers to the Branch-highway through a defined 132-way connector. Appendix A defines those features of a crate controller that affect hardware and software interchangeability. This appendix can be used either as the formal specification of a standard CAMAC crate controller Type A1 (CCAI), or as general recommendations intended to promote uniformity between crate controllers. This standard applies generally to nuclear instrumentation and may be utilized also for other applications that require modular electronic instruments units to perform input/output signal transfers for the purpose of digital data processing, normally in association with a form of controller, computer or other automatic data processor.
