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.
## Technical Specifications
• **Interface:** RS-422 Output, PMC form factor
• **Data Transfer Rate:** Up to 100 MBytes/sec
• **Parallel Data Bus:** 32-bit
• **FIFO Depth:** 8K or 32K options
• **FPDP Clock Support:** Up to 20 MHz (TTL strobe) or up to 40 MHz (PECL differential strobes)
• **Manufacturer:** Curtiss-Wright/VMETRO
## 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.
