Description

Product Description

GE VMER-64 is a 64-bit VMEbus single – board computer (SBC) built on the MIPS R4000 processor, tailored for real – time industrial control and high – speed data processing in GE’s VME – based automation systems. GE VMER-64 supports VME64 standards, integrating a floating – point unit, memory management unit, and cache for low – latency data handling in process control and monitoring applications. GE VMER-64 accommodates up to two single – width PMC modules (or one double – width) via its VME – to – PCI bridge (UNIVERSE CA91C142), enabling seamless expansion for I/O, communication, or specialized processing. GE VMER-64 adheres to IEEE P1386 and IEEE 1014 Rev.D, ensuring compatibility with legacy and modern VMEbus systems, ideal for retrofits in power generation and manufacturing. GE VMER-64 operates from – 40°C to +70°C, with industrial – grade PCB coating to withstand vibration, humidity, and electrical noise in harsh settings. GE VMER-64 includes a watchdog timer, serial port, and interrupt controller, delivering robust fault monitoring for critical applications like turbine control and factory automation.

Selection Suggestions and Precautions

Selection Suggestions

  • Choose GE VMER-64 for VMEbus systems needing 64-bit real – time processing, PMC expansion, and VME – PCI connectivity.
  • Opt for it in energy, manufacturing, or heavy industry applications requiring wide – temperature operation and legacy VME compatibility.

Precautions

  • Ensure VMEbus voltage (5V DC) is stable to protect GE VMER-64’s MIPS R4000 processor and memory circuits.
  • Use shielded cables for PMC I/O to reduce noise interference with GE VMER-64’s data transfer.
  • Match PMC modules to IEEE P1386 specs to avoid compatibility issues with GE VMER-64’s expansion slots.
  • Inspect LED indicators regularly to quickly spot VMEbus access/interrupt faults affecting GE VMER-64.
  • Do not hot – swap GE VMER-64; power down the VME chassis before installation/removal to prevent bus damage.
