Scope

This standard is applicable to nuclear instruments, and can also be used in other occasions that require the use of modular electronic equipment for signal input and output transmission to complete digital data processing. Such equipment is generally combined with control devices, computers or other automatic data processors. use together. For nuclear instrumentation and control systems, multi-chassis systems of other configurations may also be used. In detail: a. This standard applies to a system consisting of several CAMAC chassis or CAMAC compatible chassis (each chassis has a chassis controller and some modules) connected to each other by bit-parallel branch information roads. b. This standard applies to word-serial transfers between up to seven chassis and a branch drive that contain parallel transfers of not more than 24 bits as a word. c. This standard does not involve the internal structure of the branch driver of the chassis controller and the physical properties of the sub-district and information highway. It only stipulates the compatibility between the various parts of the system and the compatibility with the A1 chassis controller. those aspects of the relationship. Any equipment or system that can be said to comply with the CAMAC Branch Information Highway specification must comply with all mandatory provisions of this standard (except Appendix A). Any equipment made into a CAMAC plug-in must also comply with the regulations that must be followed in GB 5691-85. Any device claimed to be compliant with the Type A1 CAMAC chassis controller specification must comply with all mandatory provisions in Appendix A of this standard. The equipment connected to the information highway need not be fully compliant with this standard, nor must it be made into a CAMAC plug-in, but must at least be compatible with all specific operations of the branch information highway and chassis controllers specified in this standard without interfering with them
