Product Introduction
The GE PCI-5565 is a PCI form factor Reflective Memory interface from the 5565 series. It drives real-time data sharing across up to 256 nodes via fiber-optic ring in simulation, control, and test systems. Seats in standard PCI slots on industrial PCs.
This board hits 174 Mbyte/s peak with onboard SDRAM caching writes for low-latency access. Data broadcasts automatically—no CPU polling needed. Control engineers deploy it for apps demanding sync beyond Ethernet limits, like multi-axis motion or process sims. Confirm PCI bus speed match.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No PWR LED | PCI slot power short | ❌ Low | Probe +5 V / +3.3 V pins at gold fingers with Fluke 115 | Try alternate slot; check host PSU rails |
| LINK LED off | Fiber break or mismatch | ✅ High | Verify ST connectors clean; measure loss <2 dB with power meter | Swap cable; confirm 850 nm multimode |
| No ACT LED | ID conflict or open ring | ✅ High | Inspect rotary switches for unique 1-256 ID; run single-node loopback | Correct ID; power cycle sequence |
| Sync failures | Buffer overrun or noise | ✅ Medium | Dump driver stats for packet errors/FIFO full | Limit burst size; test isolated ring |
| IRQ missing | Bus resource clash | ❌ Low | Check BIOS IRQ assignments; test DMA write/read | Reassign resources; boot minimal config |
| Jitter >500 ns | Excess traffic/nodes | ✅ High | Scope transfer rates against 174 Mbyte/s cap | Cut nodes; shrink packets to 4 bytes |
Grab LED states and driver logs before calling. Cards hold up well—net issues dominate 90% of calls. Support needs photos.

Frequently Asked Questions (FAQ)
Can you hot-swap the PCI-5565?
Negative. Full system shutdown required. Live PCI insert glitches the bus and risks data wipe on the ring.
128 MB or 256 MB version?
PCI-5565 ships configurable—ours test at 128 MB standard. Same performance envelope. Extra buffer if your app floods it.
Surplus means used?
No mileage. Factory-sealed OEM excess, full inbound test. Cheaper without rep markup, same one-year coverage.
Does data persist power off?
Switches hold node ID. SDRAM dumps—volatile memory, reload on boot.
OS and PCI slot needs?
VxWorks, Linux, Windows 2000+. 32/64-bit PCI at 33/66 MHz. Full-height bracket typical.
Firmware flashable?
Yes via GE utilities. We record version post-test—request sheet with serial.
Shipping and return policy?
Stock ships next day. 1-year warranty: test-to-fail replacement. Videos per unit on demand.
Quality Control SOP
Verify GE PCI-5565 sourcing against OEM invoices and seals. Anti-fake serial scan, no PCB scratches or fiber port dings. Visual catches capacitor yellowing early.
Rack into PCI testbed with VxWorks host. Sequence PWR/LINK/ACT on boot, hammer 24-hour stress at 174 Mbyte/s across 4-node fiber loop. API validates reads/writes, interrupt generation. 500 V Megger hits >10 MΩ isolation; ground bond <1 Ω. Fluke 87 logs ripple under max draw.
Capture firmware readout, switch photos. Sign-off QC, ESD shield bag, foam cradle in carton. Dated passed label attached. Test protocol ships; video clips if you supply serial.
Technical Pitfalls & Survival Guide
❗ Duplicate Node IDs
Ring goes dark instantly. Photographed dozens of dead swaps from this. Snap old card switches first, replicate position-for-position.
❗ PCI Bus Speed Clash
66 MHz host on 33 MHz card throttles hard. BIOS logs scream it. Match specs or accept half rates. Lived through upgrade nightmares.
❗ Fiber Mode Mix
Multimode 850 nm expected—single-mode kills TX laser. Clean LC/ST ends obsessively; test continuity end-to-end.
❗ Backplane Power Trip
Full load nears 5 W—stack cards and PSU sags. Sum slot allocation, pad 20%. Underpowered rigs halted tests cold.
❗ ESD Zap
Gold fingers arc static like champs. Dry shop fried one mid-bench. Chassis-ground strap every handle
Check these boxes, field install clocks under 15 minutes. Downtime killer avoided.
