Dual I/O mode compatibility: The P2 interface supports two jumper configuration modes:

-PMC mode: compatible with MVME2300/2400, connecting PMC slot I/O to P2 backplane, suitable for peripheral backend connection;

-IPMC mode: Compatible with legacy MVME761/MVME712M adapter modules through IPMC761/IPMC712 modules, supporting traditional I/O such as SCSI, parallel ports, and multiple serial ports;

PMC expansion flexibility: Dual PMC slots support custom peripherals (such as dedicated communication cards and acquisition cards), which can be further increased in number with PMCSPAN expansion modules to meet complex I/O requirements;

Multi interface coverage: Native supports dual Ethernet and dual serial ports, and can be expanded to add SCSI, synchronous serial ports, parallel ports, and adapt to various types of peripherals such as industrial sensors, storage devices, and upper computers.

3. Software and ecological compatibility

Firmware and Debugging: Built in mature firmware monitoring program (PPCBug), supports power on self-test, hardware diagnosis, operating system boot, provides debugging tools and fault location functions, simplifies development and maintenance;

Operating system support: Compatible with multiple types of embedded operating systems, including Wind River VxWorks, Green Hills Integrity, Linux (third-party cooperative version), and adaptable to different real-time and functional requirements;

Legacy device compatibility: By using IPMC modules and adapter boards (MVME761/MVME712M), the I/O interfaces of traditional devices can be reused, reducing upgrade costs.

Typical application scenarios
