4. Product Introduction
The GE VME-7700RC (also referenced as VMIVME-7700RC) is a 6U VMEbus single board computer (SBC) designed for embedded industrial systems that require reliable processing, flexible I/O, and network connectivity. It’s based on an Intel ultra low voltage Celeron processor (400 MHz or 650 MHz) with up to 512 MB of SDRAM, optional 1 GB CompactFlash storage, and dual front-panel Ethernet ports for networked operation.
This SBC integrates a robust VMEbus interface using the Tundra Universe II bridge, a PMC expansion site for additional I/O, and multiple serial/USB ports for field device integration. It is widely deployed in embedded control, test systems, process automation, and legacy VME applications where sustained performance and field-deployable designs are critical.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Board won’t boot or stay powered | No backplane power / wrong VME slot | ✅ High | Verify VME rack 5 V, ±12 V with DC meter | Confirm backplane voltages and slot alignment |
| No BIOS output serial/console | Incorrect console settings / no connection | ⚠️ Medium | Connect RS-232 to PC at correct baud | Confirm BIOS settings; try PS/2 keyboard if available |
| Ethernet LAN not active | Cable or switch mismatch | ⚠️ Medium | Check link LED on RJ45 | Use known good cable and link test |
| PMC site unresponsive | Unsupported PMC card | ⚠️ Medium | Remove/replace PMC card | Use compatible PMC mezzanine per spec |
| System crashes under load | Thermal or power issue | ⚠️ Medium | Check chassis airflow & heat sink seat | Ensure forced cooling and proper seating |
Note: Most SBC faults trace back to rack power issues, backplane misalignment, or peripheral configuration. Verify rack voltages and connectors before suspecting the SBC itself.
6. Frequently Asked Questions (FAQ)
Q1: What exactly is the GE VME-7700RC?
A: It’s a 6U VMEbus single board computer with an Intel ultra low voltage Celeron CPU, dual Ethernet, PMC expansion, and VMEbus interface — used for industrial embedded control or legacy rack systems.
Q2: What environments is this board designed for?
A: It’s intended for embedded and industrial systems where a rugged, low-power SBC is needed in a VME chassis — ranging from automated test rigs to process control frameworks.
Q3: What operating systems can it support?
A: Typical OS support includes VxWorks, QNX, Linux, and legacy RTOS environments on embedded boards. Booting from Ethernet or CompactFlash is common in field deployments.
Q4: Is this module still manufactured?
A: No — it’s a legacy VME SBC originally from GE Fanuc embedded systems and later under Abaco Systems; current supply is mainly new surplus or refurbished stock.
Q5: Why might a system integrator choose this board?
A: For fielded VME installations and legacy support, this SBC provides standard VMEbus services, PCI/PMC extension, network connectivity, and embedded extenders.
Q6: Is there firmware/BIOS support available?
A: Legacy BIOS and boot firmware are stored in reprogrammable memory — confirm version and settings before commissioning. Testing in a lab setup with console access is recommended.
