VMIVME-7750-466000/350-027750-466000 K
Overview
The Abaco Systems VMIVME-7750-466000/350-027750-466000 K is a high-performance 6U single-slot VMEbus Single-Board Computer (SBC) engineered for industrial control, data acquisition, and mission-critical computing environments. Based on the mature VME (VersaModule Eurocard) bus architecture, it features a rugged, passive-cooled design to ensure reliability in harsh industrial conditions. Though entering the Restricted Production Phase (RPP), this model remains a key solution for applications requiring robust processing and expandability.
Functional Features
(1) High-Performance Processing
Equipped with an Intel Pentium III processor (up to 1.26 GHz), the SBC delivers 32-bit addressing and a 64-bit data bus. Its superscalar architecture supports three instructions per clock cycle, enhanced by dynamic branch prediction, independent instruction/data caches, and MMX™ technology for efficient multitasking and complex algorithm execution.
(2) Enhanced Memory & Storage
- Memory: Up to 512 MB of PC133 SDRAM via a 144-pin SODIMM, with dual-port DRAM connectivity to the VMEbus for optimized data transfer.
- Storage: IDE interface for local drives and bootable flash memory (optional) for system initialization.
(3) Versatile I/O Capabilities
- VMEbus Interface: Compliant with VMEbus Rev. C.1, supporting transparent PCI-to-VMEbus bridging for multi-CPU system control.
- Ethernet: Two Intel controllers (82559 and ICH2-integrated) for 10/100BaseTX connectivity, with remote boot support via Netware, TCP/IP, or RPL.
- Graphics: AGP graphics adapter (815E chipset) supports SVGA resolutions up to 1600×1200×256 colors for industrial visualization.
- Expansion: One PMC site for custom I/O modules (e.g., serial, USB, analog/digital I/O).
(4) Broad OS Compatibility
Supports real-time OS (VxWorks), Linux, and Windows, enabling flexible deployment across industrial automation, communications, and data processing applications.

Working Principle
(1) System Boot Process
Upon power activation, the onboard power management circuit conditions input voltage for components. The processor loads BIOS from reprogrammable flash memory, initializing hardware (memory, timers, I/O) and booting the OS—either from local IDE/storage or remotely via Ethernet using Bootware® technology.
(2) Data Processing Mechanism
The Pentium III processor parses tasks through pre-defined algorithms, interacting with SDRAM for data operations. In industrial setups, it processes real-time sensor data, while the AGP adapter handles graphics-intensive outputs. VMEbus coordinates data transfer with external devices, and Ethernet manages network communication via protocol encapsulation/decapsulation.
(3) Bus Architecture
The transparent PCI-to-VMEbus bridge allows the SBC to function as a system controller or peripheral CPU in multi-processor configurations, ensuring seamless data exchange across the VMEbus ecosystem.
Operation Guide
(1) Pre-installation Preparations
- Compatibility Check: Verify VMEbus slot specifications (electrical parameters, power supply) and ensure alignment with VMIVME-7750-466000/350-027750-466000 K.
- ESD Protection: Use anti-static wristbands and tools; ensure the installation environment is ESD-controlled.
(2) Module Installation
- Open the VME chassis and locate a 6U slot.
- Align the SBC’s VME interface with the slot, insert vertically, and secure with screws.
- Connect power, IDE cables (if applicable), and PMC modules per application requirements.
(3) System Configuration
- Storage & Network: Set up IDE drives or configure remote boot via Ethernet (IP, subnet mask, gateway).
- OS & Drivers: Install the target OS (e.g., Linux) and relevant drivers, ensuring PMC modules are detected and configured.
(4) Troubleshooting
- Boot Issues: Check power connections, flash memory integrity, and BIOS settings for boot order.
- Network Failures: Test Ethernet cables, update network drivers, and verify protocol configurations (e.g., TCP/IP settings).
- I/O Malfunctions: Inspect PMC module installation, update firmware/drivers, or replace faulty components if necessary.
