Interface circuit for communicating between two data highways

摘要: An interface circuit for use in a data transmission system is designed to be used not only between highway and device but also link highways can commanded enter status which commands sent it on one are modified out as second so that controller the control devices highway, with extension, if desired, third or beyond. To achieve this, has two ports each connection respective of substantially identical highways, means responsive signals received at either port establish different statuses interface. For inter-highway communication, command signal particular form produce other port.
