The Radisys EXM10 is an Ethernet interface card engineered for embedded PC systems using the EXM expansion interface standard. It delivers dual Ethernet connectivity through a DB-15 DIX/MAU connector for transceiver cable integration and a BNC connector for thin Ethernet (RG58) cable connections. The module operates on an ISA bus-equivalent electrical architecture, enabling compatibility with standard PC software across DOS and Windows environments.
