THE MODULAR RANGE INTERFACE (MODRI) DATA ACQUISITION CAPABILITIES AND STRATEGIES

Abstract

The Modular Range Interface (ModRI) is a reliable networked data acquisition system used to acquire and disseminate dissimilar data. ModRI’s purpose is to connect TSPI systems to a central computer network. The modular hardware design consists of an SBC, COTS network interfaces, and other COTS interfaces in a VME form factor. The modular software design uses C++ and OO patterns running under an RTOS. Current capabilities of ModRI include acquisition of Ethernet, PCM data, RS-422/232 serial data, and IRIG-B time. Future strategies might include stand-alone data acquisition, acquisition of digital video, and migration to other architectures and operating systems.
