Abstract:
A modular bus interface for use in a bus data analyzer, the modular bus interface comprising:an expansion card, the expansion card providing an interface to the bus data analyzer;a link layer module mounted on the expansion card, the link layer module including a link layer device for implementing a test bus;a physical layer module including a physical layer device for implementing the test bus, at least one test bus connector, and a memory device for storing physical layer device identification data; anda releasable connector, the releasable connector providing electrical and mechanical connection between the link layer module and the physical layer module, the releasable connector providing:i) connection for data and control signals between the physical layer device and the link layer device;ii) connection for power to the physical layer device; andiii) connection between the memory device and the link layer device;and wherein the releasable connector allows the physical layer module to be removed and replaced with another physical layer module as needed to test different test bus implementations.
