– Key Features
• Modular slot installation in Radisys EXM-compatible chassis
• Configurable interrupt and address mapping eliminates port conflicts
• Third-party add-in card support (motion controllers, SERIPLEX, SERCOS, LonWorks interfaces)
• Software-configurable port settings via EXM bus architecture
– Typical Applications
Legacy serial/parallel device integration in industrial control systems. Printer and scanner connectivity in embedded environments. Multi-protocol expansion for real-time embedded platforms requiring deterministic communication.
– Compatibility & Integration
Designed for installation in EXM slots within Radisys EMC chassis. Compatible with embedded PC systems supporting EXM expansion interfaces. Supports third-party software configurations. Proper address and IRQ assignment prevents conflicts with existing system ports.
