The VME162PA-344SE-2G is based on the Motorola MVME162PA-344SE architecture and features a 32 MHz MC68040 processor, 16 MB ECC SDRAM, battery-backed SRAM, integrated Ethernet, SCSI, and dual IndustryPack interfaces for modular expansion.
Product Introduction
The GE VME162PA-344SE-2G is a rugged 6U VMEbus embedded processor board derived from the Motorola MVME162PA family. It combines a 32-bit Motorola MC68040 processor with ECC-protected memory and integrated communications to deliver deterministic performance for demanding industrial and embedded control applications. The board is widely used in legacy automation systems, military electronics, transportation, and scientific instrumentation.
The module integrates SCSI, Ethernet, and IndustryPack expansion while supporting standard VMEbus architectures, making it suitable for real-time operating systems such as VxWorks and OS-9. Its modular design allows system integrators to add application-specific I/O while maintaining long-term platform reliability.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance | Quick Check | Recommendation |
|---|---|---|---|---|
| Board does not boot | Missing VME backplane power | ✅ High | Measure +5 V and ±12 V supply rails | Verify chassis power before replacing the board |
| No Ethernet communication | Network cable or interface fault | ✅ High | Check Ethernet link LEDs and network settings | Verify cable and interface configuration |
| SCSI device not detected | SCSI termination or cable issue | ✅ High | Inspect SCSI ID and termination | Correct SCSI configuration |
| Memory errors | Faulty SDRAM or memory corruption | ✅ High | Run board diagnostics | Verify memory integrity |
| VMEbus communication failure | Backplane connector or slot issue | ✅ High | Inspect VME connectors and slot assignment | Reseat the board and verify backplane operation |
| Unexpected watchdog reset | Software or power instability | ⚠️ Medium | Review system logs and monitor supply voltage | Check RTOS configuration and power quality |
Field Tip: Most MVME162PA failures are caused by VME backplane power issues, aging electrolytic capacitors, SCSI configuration problems, or connector oxidation rather than CPU failure. Before replacing the VME162PA-344SE-2G, verify the chassis power rails, inspect VME connectors, confirm SCSI termination, and review boot diagnostics.
