This paper describes a MAP (Manufacturing Automation Protocol) based LAN (Local Area Network) node implemented in VME. It provides a high speed communications channel for distributed intelligence systems. The node has a 20 MHz 32 bit processor which executes the software layers of the OSI communications model, and a LAN coprocessor which carries out the lowest level of the OSI functions, including Physical and Medium Access Control layers. The node includes 512{Kappa} bytes of dual ported RAM for use as a shared resource on VME which supports block transfers. A real time multitasking operating system supports all VME and MAP software enabling multiple communication processes and optimization of local resources.
