GE VMIVME-7750-746001 VME Single Board Computer Board

• Advanced VMEbus Bridging: Powered by the Tundra Universe II interface chip to ensure stable, high-throughput 64-bit Master/Slave PCI-to-VME bus conversions.

• Solid-State Boot Media: Integrates a secondary IDE interface coupled to a CompactFlash site, allowing full operating system boot operations from solid-state storage.

• Non-Volatile System Memory: Provides 32 Kbytes of battery-backed SRAM that retains critical machine tracking states and variables through total power loss cycles.

• Dual Networking Infrastructure: Features an internal Intel 815E chipset paired with an independent 82559 controller to give two separate RJ-45 ports with remote LAN boot capabilities.

• Mezzanine Card Scalability: Includes an IEEE P1386 compliant 5V PMC slot, allowing system engineers to add custom I/O or communication hardware directly to the front face.

The GE VMIVME-7750-746001 (also cataloged under the assembly tag 350-027750-746001 P) functions as a self-contained IBM PC/AT-compatible computer adapted into a ruggedized VME rack layout. Developed to sustain harsh industrial operating environments where mechanical vibrations or extreme temperature fluctuations would cause standard desktop computers to fail, this single-board computer acts as an processing engine for complex instrumentation and automation frames.

The structural core of the board balances high-speed local processing with efficient backplane communication. While the onboard Intel Pentium III processor runs software stacks, operating systems, and localized math filters, the embedded Universe II bridge handles low-latency VMEbus calls. This allows the card to run as a designated Slot 1 System Controller complete with a programmable arbiter (PRI, SGL, and RRS routing modes supported). If localized memory alignment does not require endian data translation, the card offers an exclusive hardware "Bypass" transfer mode to maximize data transmission across VME backplane windows.

• Distributed Control Systems (DCS): Running as the primary processing core for heavy industrial control layer modules and plant master panels.

• Aerospace and Test Simulations: Processing real-time diagnostic inputs and telemetry variables across military and civil test equipment.

• Power Generation Control: Executing turbine tracking software and balancing auxiliary loops within large power plants.

• Radar and Navigational Arrays: Providing high-speed processing capabilities for legacy maritime and military radar signals.

Q: What is the purpose of the "P" suffix on the 350-027750-746001 P part number? A: The trailing letter generally indicates the specific manufacturing revision, component layout version, or lead-free plating compliance standard implemented by the factory during that specific production run.

Q: Do the front-panel serial ports use standard serial cable pins? A: No. Because space is restricted on the single-slot front panel, the board uses two high-density micro-DB-9 connectors. Standard 9-pin serial cables require an external adapter cable (VMIC Part Number: 360-010050-001).

Q: How does the Watchdog Timer handle a system software hang condition? A: Once enabled by your local software routines, the Watchdog must be continually refreshed within a defined window. If it times out due to a crash, an internal jumper allows you to either force a hard hardware reset, trigger a Non-Maskable Interrupt (NMI), or assert a VMEbus SYSFAIL signal.

Q: Can this board boot over a network if no local CompactFlash card is inserted? A: Yes. The board's BIOS includes embedded BootWare utilities from Lanworks Technologies, allowing the VMIVME-7750 to execute remote network boots via TCP/IP, NetWare, or RPL network structures
