The Abaco Systems VMIVME-7750-656000, also cataloged as the VMIVME-7750 6U VMEbus Single Board Computer, operates as a dedicated hardware component for real-time computational execution and high-speed data processing within VME64 industrial and defense control platforms. Powered by an Intel Pentium III processor architecture and utilizing a Tundra Universe II bridge, this single-slot board interfaces directly with the backplane to execute VMEbus master/slave operations, high-density I/O routing, and graphics processing without requiring external CPU expansion cards.

The Abaco Systems VMIVME-7750-656000 relies on the Tundra Universe II PCI-to-VMEbus bridge to achieve deterministic backplane bus communication velocity across VME64 backplanes. Internal registers handle DMA transfers and direct memory mapping, minimizing latency when communicating with secondary I/O modules, reflective memory cards, or safety-critical controllers. Strict firmware flash compatibility ensures stable low-level system initialization (BIOS execution) across real-time operating systems including VxWorks, QNX, Linux, and Windows, maintaining timing synchronization during continuous operational cycles.
Q: Does the board support hot-swapping inside an active VME chassis?
A: No, standard VMEbus architecture requires complete removal of backplane power (+5 VDC, +12 VDC, -12 VDC) prior to inserting or extracting the board. Attempting to seat or unseat the module during active backplane operation risks electrical damage to the gold-plated DIN connectors and PCI-to-VME bridging silicon.
Q: How is primary system boot configured if no external hard drive is connected?
A: System boot relies on the onboard Type II CompactFlash socket or network booting via the 10/100 Mbps Fast Ethernet port. System engineers configure the BIOS boot priority sequence using a connected PS/2 keyboard and SVGA display monitor during post-assembly power-on.
Inspect the 6U VMEbus backplane card edge connectors and verify that all PIN connections are clean and free of physical debris before mounting. Power down the VME enclosure completely and disconnect incoming main power feeders to ensure zero voltage on the backplane rails.
Slide the board smoothly into the target slot along the chassis card guides until the dual ejector handles engage the upper and lower rails. Apply firm, steady pressure on both handles simultaneously to seat the DIN connectors securely into the backplane. Tighten the top and bottom front panel retaining screws using a standard flathead screwdriver to ensure positive ground contact with the chassis frame and to prevent vibration-induced dislodgement. Connect shielded Category 5e cables for Ethernet communications, keeping signal cabling isolated from high-voltage AC lines or heavy inductive motor loads inside the cabinet.
