Abstract: In order to decrease the cost and reduce dimension, the standard signals of CAMAC bus are analyzed. 6 type bus signals are produced by adopting TTL logic circuit. Hence the simplified design of CAMAC bus control unit is realized.Electro circuit principle and subprogram is introduced in detail. In this control unit, the Bus Control right can be obtained via operating the general I/O interface. Its stability and reliability are proved by application and can be used in module testing and system miniaturizing too.
