GE VMIVME-7452

The GE VMIVME-7452 is a high-performance VMEbus Single Board Computer (SBC) under the portfolio of GE Fanuc Automation (a business unit of General Electric). Specifically engineered for demanding real-time industrial control and data acquisition applications, it serves as the "system brain"—a core component in automation systems.

Built around a high-performance Intel Pentium III processor, the GE VMIVME-7452 integrates robust computing power, abundant memory, multiple industrial interfaces, and one PMC (PCI Mezzanine Card) expansion site onto a standard 6U VME board. It supports real-time operating systems (RTOS) such as VxWorks, LynxOS, and Windows NT Embedded, enabling it to handle complex control algorithms, massive data operations, and high-speed communication tasks.

Its core value lies in delivering an integrated, rugged, and high-performance embedded solution. It is ideally suited for use as a main controller in fields with extreme requirements for reliability, determinism, and harsh environment adaptability—including defense, aerospace, industrial automation, and simulation testing.

Product Specifications

• Product Model: VMIVME-7452
• Manufacturer: General Electric (GE) / VMIC
• Product Type: VMEbus Single Board Computer (SBC)
• Processor: Intel® Pentium® III Processor (up to 1.26+ GHz)
• System Chipset: Intel® 815E
• Memory: On-board integrated 512 MB SDRAM (expandable via SO-DIMM)
• On-board Flash Memory: 64 MB solid-state drive (for storing operating systems and applications)
• Graphics Controller: Integrated Intel® 815 Graphics
• Interfaces: 2x 10/100 Ethernet (RJ45), 2x Serial (RS-232), 2x USB 1.1, PS/2 Keyboard/Mouse, EIDE, Floppy
• Expansion Bus: 1 PMC (PCI Mezzanine Card) expansion site
• VMEbus Interface: Master controller, supporting A32/A24/A16, D32/D16/D08 (EO) addressing
• Power Consumption: +5 V @ 5.0A (typical), +3.3 V @ 3.5A, +12 V @ 0.3A, -12 V @ 0.1A
• Operating Temperature: 0°C to +55°C (suitable for control cabinet environments)

• At the center of the board are the Intel® Pentium® III processor and Intel® 815E system chipset, forming the computing core. A heatsink with a metal clip is mounted above the processor to ensure effective heat dissipation.
• The front side of the board integrates high-capacity SDRAM memory modules and flash memory chips (for storing operating systems and applications).
• All front-panel I/O interfaces—including two 100-Mbps Ethernet ports, two serial ports, and USB ports—are located on the front edge of the board, facilitating easy connection to external devices.
• The upper area of the board houses one PMC expansion site, which connects to the host via the PCI bus. This allows users to add additional functions (e.g., motion control cards, high-speed digital I/O cards, or special communication interface cards) based on specific requirements.
• The P1 and P2 connectors at the bottom of the board are used for inserting into the VME chassis backplane, enabling communication with other system modules and power supply.

 Key Features and Advantages

Powerful Computing Performance and Integration

Excellent Scalability and Flexibility

High Reliability and Ruggedness

Application Fields

• Defense and Aerospace: It is employed in radar systems, flight simulators, electronic warfare systems, and test benches for real-time data processing and control.
• Industrial Automation: As a high-end real-time controller, it supports complex motion control systems, robot controllers, and data acquisition systems.
• Other Fields: In medical imaging, traffic control, and communication infrastructure, the VMIVME-7452 serves as the core computing engine for building powerful, reliable, and scalable embedded platforms.

6. Installation and Maintenance

 Pre-Installation Preparation

1. Turn off the power of the VME chassis and disconnect all power cables.
2. Operators must wear an anti-static wristband strictly to prevent electrostatic damage.
3. Confirm that there is an available 6U slot in the chassis.
4. Check if the jumper settings on the board (e.g., boot device selection) meet application requirements.
5. If a PMC card is used, install it firmly into the PMC site of the SBC first.

Maintenance Recommendations

1. Ensure the chassis cooling fans operate normally and the ventilation is unobstructed to prevent dust accumulation.
2. Regularly check if the board is securely seated in the slot, especially in vibrating environments.
3. Perform regular backups of system software and critical data.
4. In case of a fault, the board is usually repaired by replacing the entire unit.
5. Any firmware or BIOS updates must be performed in strict accordance with official guidelines.
