Introduction

This document describes the Multi-purpose Serial Data Link (MSDL) card. This card provides multiple interface types with four full-duplex serial I/O ports that can be independently configured for various operations. Peripheral software downloaded to the MSDL controls functionality for each port. Synchronous operation is permitted on all MSDL ports. Port 0 can be configured as an asynchronous Serial Data Interface (SDI).

An MSDL card occupies one network card slot in Large System Networks, or Core Network modules and communicates with the CPU over the CPU bus and with I/O equipment over its serial ports. It can coexist with other cards
