The RadiSys EXP-BP2 is an L-shaped subplane module that provides essential signal routing and connectivity within VMEbus embedded systems. It interfaces with the VMEbus backplane via a P2 connector and supports a processor and up to two EXM (Expansion Module) units through dedicated connectors designated as EXM slot 0 (lower) and slot 1 (upper). The module integrates peripheral expansion capability into demanding industrial computing and embedded applications.

– Typical Applications
The EXP-BP2 serves industrial control systems, embedded PCs, and VMEbus-based computing platforms requiring integrated mass storage connectivity. It enables systems to expand processor capability through modular peripheral attachment in space-constrained form factors.
– Compatibility & Integration
Designed for RadiSys VMEbus embedded systems including the EPC-8A platform. Interfaces with EXM expansion cards that bridge to storage modules such as the EXP-FDM and EXP-MS/MX units. Mass storage configurations using this subplane support MS-DOS environments. Third-party support and lifecycle supply available through authorized suppliers.
