GE VMIVME‑7750‑746000 VME Single Board Computer Module

Technical Specifications: Processor: Intel Pentium III processor, 133MHz front‑side bus, 512KB L2 cache System Memory: Up to 512MB PC‑133 SDRAM via SODIMM socket Non‑Volatile Memory: 512KB NVRAM for critical data retention Storage Interface: IDE interface, supports CompactFlash bootable storage Graphics Controller: Integrated AGP SVGA controller, maximum resolution 1600×1200 Communication Interface: Dual 10/100Mbps Ethernet, multiple RS‑232/RS‑422 serial ports Expansion Slot: One PMC expansion site for additional functional mezzanine card Bus Protocol: VME64 backplane bus protocol Operating Power Supply: +5VDC, +12VDC, ‑12VDC from VME backplane Operating Temperature: 0°C to +55°C Storage Temperature: ‑50°C to +85°C Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard 6U single‑slot VME Eurocard form factor Certifications: CE, UL, industrial EMC compliance standards

Functional Features: Provides powerful embedded computing capability for VME‑bus system master control. Transparent PCI‑to‑VME bridge supports system controller and peripheral CPU working mode. Complete self‑diagnosis for processor, memory, power supply and on‑board peripheral circuits.

Application Scenarios: Main control unit for VME‑bus industrial automation rack. Real‑time simulation and hardware‑in‑loop test system. Data acquisition and processing system for power plant equipment. Complex process control system for petrochemical industry. Distributed industrial embedded computing platform.

Structural Characteristics: Standard 6U single‑slot plug‑in VME module mechanical structure. Front‑panel LED indicators for power, fault, network and running status. Front‑panel external interfaces including Ethernet, serial port, VGA and keyboard‑mouse port.

Working Principle: VME‑bus data signal is transmitted to module through backplane golden‑finger connector. On‑board processor completes logic calculation, data analysis and bus resource scheduling. PCI‑VME bridge realizes data interaction between local peripheral and VME backplane bus.

Installation Requirements: Insert module into designated slot of standard 6U dual P1/P2 VME rack. When acting as system controller, install to slot 1 of chassis. Strictly implement cabinet grounding according to system technical specification. Separate power cables and signal cables inside cabinet to reduce signal crosstalk.
