Abstract
A data monitoring system includes a display unit for communicating with an operation that has characteristics which are to be monitored, a recording unit located remotely from the environment of the monitored operation, and a local area network interconnect circuit for connecting the display and recording units. The local area network circuit allows multiple display units to be connected to a single pair of electrical conductors. Each display unit has at least one dual microcomputer configuration interconnected by a shared dual port random access memory. A third microcomputer is located in the recording unit for communicating over the local area network circuit with one of the microcomputers in the display unit.
