Abstract

This article describes the Network Control System (NCS) Standard Computer Interface hardware, including the interface cable, the line drivers, line receivers and line terminating network. It describes in considerable detail the timing specifications for the interface timing control signals for continuous data transfer as well as for asynchronous byte transfer. A set of control logic which complies with these timing specifications has been designed for and successfully checked out in connection with the Star Switch Controller (SSC). This control logic, which includes synchronization and noise filter operations, is described in detail. Transfer rates for variable cable lengths are listed.
