Curtiss-Wright / VMETRO DPIO-DO RS-422 Output PMC Module

The Curtiss-Wright/VMETRO DPIO-DO is an RS-422 output PMC (PCI Mezzanine Card) module engineered for high-speed digital parallel I/O in data acquisition and control systems. Delivering up to 100 MBytes/sec, this 32-bit parallel interface card integrates Front Panel Data Port (FPDP) compatibility for direct, high-bandwidth streaming between converters and processing units in industrial and military environments.

Key Features

Front Panel Data Port (FPDP) compatibility with -FI and -FO module versions enables plug-and-play integration into existing parallel data systems

Selectable FIFO configurations (8K or 32K) accommodate varying buffer depth requirements

Dual clock rate support via TTL and PECL differential strobes provides flexibility across legacy and modern system architectures

32-bit parallel data path optimized for large-volume sensor data streaming

Typical Applications Designed for high-speed digital data generation and acquisition workflows, the DPIO-DO facilitates direct transfer of raw sensor data from Analog-to-Digital Converters (ADCs) or Digital-to-Analog Converters (DACs) to processors, memory, or storage subsystems. Particularly suited to applications demanding sustained, high-bandwidth parallel data movement without intermediate protocol translation.

Compatibility & Integration Mounts in standard PMC card slots on PCI or PCI-X carrier boards. FPDP standard compliance allows integration with systems already standardized on this parallel interface protocol. Designed for use with PMC carrier boards such as the SVME/DMV-210. Curtiss-Wright products are engineered for demanding industrial and military operational environments.
