GE VMIVME-7750-746 Single Board Computer Module
GE VMIVME-7750-746
GE VMIVME-7750-746 is a high-performance VMEbus Single Board Computer (SBC), which belongs to the powerful VMIC product line under GE Fanuc Automation (now integrated into Emerson). It is specifically designed for demanding real-time control and data acquisition applications. Acting as the “system brain” in automation systems, this product integrates robust computing power, abundant memory, and multiple industrial interfaces into a standard 6U VME board. Based on a high-performance Pentium III processor, GE VMIVME-7750-746 can run real-time operating systems (RTOS) such as VxWorks, LynxOS, or Windows NT Embedded, enabling it to handle complex control algorithms, massive data operations, and high-speed communication tasks. Its core value lies in providing an integrated, rugged, and high-performance solution, making it ideal for use as an embedded controller in fields requiring extremely high reliability and determinism, such as national defense, aerospace, industrial automation, and simulation testing.

Structure and Composition
GE VMIVME-7750-746 adopts a standard 6U VME board design, featuring a highly integrated structure. At the center of the board are the Intel® Pentium® III processor and Intel® 815E system chipset, which form the computing core. A heatsink with a metal clip is installed above the processor to ensure heat dissipation. The front side of the board integrates high-capacity SDRAM memory chips and flash memory chips for storing operating systems and applications. All front-panel I/O interfaces—including two Gigabit Ethernet ports, two serial ports, and USB ports—are provided on the front end of the board, facilitating connections to external devices. The upper area of the board is equipped with one or two PMC expansion sites, which are connected to the host via the PCI bus. This allows users to add additional functions (such as motion control cards, high-speed digital I/O cards, or special communication interface cards) according to specific needs. The P1 and P2 connectors at the bottom of the board are used to insert into the VME chassis backplane, enabling communication and power supply with other modules in the system.
Key Features and Advantages
- Powerful Computing Performance and Integration: At the time of its release, GE VMIVME-7750-746 delivered top-tier processing capabilities, easily handling complex mathematical operations and real-time control tasks. Its highly integrated design condenses the CPU, memory, graphics control, network, and multiple I/O interfaces into a single board, significantly reducing system size and complexity while improving overall reliability.
- Excellent Scalability and Flexibility: Through one or two PMC expansion sites, the functionality of this SBC is greatly extended. Users can select a variety of commercially available PMC modules to customize the system, meeting almost any application requirement—from additional communication protocols to dedicated data acquisition. This modular approach provides unparalleled flexibility and protects long-term investments.
- High Reliability and Ruggedness: The board is designed in accordance with strict industrial standards, using high-quality components and mature manufacturing processes to ensure stable operation under a wide temperature range, vibration, and shock conditions. Its design is suitable for 24/7 continuous operation in mission-critical applications, with an extremely long Mean Time Between Failures (MTBF), making it the cornerstone of building high-availability systems.
Application Fields
GE VMIVME-7750-746 is mainly used in embedded fields with extreme requirements for computing performance and reliability. In the national defense and aerospace sectors, it is applied to real-time data processing and control in radar systems, flight simulators, electronic warfare systems, and test benches. In the industrial automation field, it serves as a high-end real-time controller for complex motion control systems, robot controllers, and data acquisition systems. Additionally, in medical imaging, traffic control, and communication infrastructure, VMIVME-7750-746 is the core computing engine for building powerful, reliable, and scalable embedded platforms.
Installation and Maintenance
Pre-Installation Preparation
Before installing GE VMIVME-7750-746, the power supply of the VME chassis must be turned off and all power cables disconnected. Operators must wear an anti-static wristband strictly. Confirm that there is an available 6U slot in the chassis. Check whether any jumper settings on the board (such as boot device selection) meet the application requirements. If a PMC card is used, install it firmly into the PMC site of the SBC first.
Maintenance Recommendations
Maintenance of the board mainly involves preventive measures. Ensure that the chassis cooling fans work properly and the ventilation is good to prevent dust accumulation. Regularly check whether the board is firmly seated in the slot, especially in vibrating environments. Back up system software and critical data regularly. In case of a fault, the board is usually repaired by replacing the entire unit. Any firmware or BIOS updates should be performed in strict accordance with official guidelines.
