5、 designers as well as systems engineers, and is limited to interface characteristics - physical, functional, and electrical. This standard does not describe the input/output (YO) of any equipment. By specifying functional interface requirements, this standard does not specify the specific interface
6、type requirements for any system application; rather it describes functional characteristics of the interface signals. Appendix A provides information regarding interconnection requirements of this standard. Appendix A contains the general philosophy of the U0 interfaces as specified in this standar
7、d. Appendix B contains special requirements associated with CP-642AE3 and CP-789 computers. Appendix C provides design guidance for Type E interface including: burst transfer mode, error detection, and conformance tests. For the Type K interface, appendix D defines the Type K interface command set.
8、Appendix E provides design guidance for Type K interface. iii Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-l397C(SH) 1 June 1995 .
