Product Introduction
ROLA serves as a foundational 32-bit VMEbus single board computer for legacy industrial and aerospace applications. This unit is driven by a 25 MHz MC68030 processor and includes 2 MB of base RAM expandable to 16 MB.
Unlike modern SBCs, this module integrates 512 KB of flash memory and dual RS-232C serial ports directly on the board. It supports VxWorks and pSOS real-time operating systems. Verify with OEM datasheet for exact memory and flash configurations.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: We trace source serial numbers against factory records. Visual inspection checks for pin corrosion or PCB scratches.
- Live Functional Test: Power-on self-check runs first. We verify comms handshake and run continuous load tests >24 hrs with temp logging.
- Electrical Parameter Test: Insulation resistance gets tested at 500 V Megger (>10 MΩ required). Ground continuity is mandatory.
- Firmware Verification: Read and record firmware version immediately. Photograph DIP switch and jumper settings before racking.
- Final QC & Packaging: Seal in anti-static bag. Apply QC Passed label with test date and engineer initials.
Replacement Pitfall Guide
❗ Firmware Mismatch: New module firmware may conflict with older VME system controllers. Always check 147Bug monitor and BSP compatibility.
❗ DIP Switch / Jumper Misconfiguration: Factory defaults rarely match field settings. Verify VMEbus system controller selection and memory base address switches.
❗ Terminal / Cable Incompatibility: Pin definitions change between revisions. Check P2 connector wiring carefully if using legacy serial or SCSI peripherals.
❗ Power Supply Mismatch: Calculate total rack power draw. Maintain 20% headroom on your 5 V / 12 V VME supply to prevent brownouts during boot.
❗ ESD Damage: Use anti-static mat and wrist strap. Dry environments increase failure risk during handling.
Keep these in mind and you’ll cut 90% of rework time.
