Description
🔹 Product Overview
The XYCOM XVME-545 is a legacy VMEbus module designed for use in industrial computer and automation systems based on the VMEbus architecture. It is identified in available hardware listings with part number 70545-002 Rev. 1.1 and the module designation IN12S1B3.
The XVME-545 is intended for installation in a compatible VMEbus chassis and backplane as part of a larger industrial computing or control platform. Xycom XVME systems use standardized VMEbus and I/O architecture concepts for module addressing, identification, status monitoring, interrupt control, and communication between host processors and I/O modules.

🖥️ VMEbus System Integration
The XVME-545 operates as a module within a VMEbus-based industrial computer architecture. A VMEbus system typically consists of a chassis, backplane, host processor or controller, memory, I/O modules, and application-specific interface boards.
Correct operation therefore depends on the complete system configuration rather than the module alone. The VMEbus backplane, slot assignment, addressing configuration, interrupt settings, and associated controller should all be checked before installing a replacement module.
Xycom’s XVME architecture uses standardized mechanisms for module addressing and identification, helping the host processor communicate with installed modules through the VMEbus environment.
🔌 Installation & Backplane Compatibility
XVME modules are designed to be installed in a VMEbus card cage. Installation documentation for the XVME family specifies powering down the VMEbus and associated external supplies before inserting or removing boards and checking relevant jumper configurations before installation.
Recommended procedure:
- Shut down the host system and disconnect applicable power.
- Confirm that the chassis and backplane are compatible with the XVME module.
- Record the existing slot position and jumper configuration.
- Inspect the module and its backplane connectors.
- Align the board with the card-cage guides.
- Carefully seat the module into the backplane connector.
- Verify that the board is fully engaged without excessive insertion force.
- Restore system power.
- Check host-system diagnostics and module recognition.
- Verify normal operation of the associated control or computing application.

🔍 Troubleshooting
Module is not recognized:
Check the board seating, VMEbus backplane, slot assignment, addressing configuration, and jumper settings.
System fails during startup:
Confirm that the module is installed in the correct slot and that all required system boards are present.
Intermittent communication:
Inspect the backplane connectors and board edge contacts for contamination, oxidation, or mechanical damage.
Unexpected system behavior:
Verify module identification, address configuration, interrupt settings, and compatibility with the host processor.
No operation after replacement:
Compare the replacement board’s complete identification, revision, and configuration with the original unit before assuming a hardware failure.
🔧 Maintenance
For long-term storage, place the XVME-545 in an antistatic protective package and keep it in a clean, dry environment.
Recommended practices include:
- Use ESD protection when handling the board.
- Protect the VMEbus connectors from contamination.
- Inspect edge contacts before installation.
- Avoid unnecessary removal and insertion cycles.
- Check jumpers and configuration settings before commissioning.
- Maintain a tested spare for critical legacy systems.
- Record board revisions and system slot assignments.
♻️ Replacement Considerations
The XVME-545 should be matched by complete part identification rather than by the XVME family name alone.
For replacement applications, compare:
- XVME model number
- Board part number
- Revision level
- Module identification
- VMEbus chassis
- Backplane configuration
- Slot assignment
- Jumper configuration
- Host processor compatibility
- Existing system software and configuration
The available XVME-545 identification 70545-002 Rev. 1.1 is especially useful when sourcing a like-for-like replacement.
❓ Frequently Asked Questions
What is the XYCOM XVME-545?
It is a legacy XYCOM VMEbus module designed for integration into compatible VME-based industrial computer and automation systems.
What is 70545-002 Rev. 1.1?
It is an associated part-number and revision reference for the XVME-545 module.
Is the XVME-545 a standalone computer?
No. It is a VMEbus module intended to operate within a compatible chassis, backplane, controller, and system configuration.
Can it be installed in any VME chassis?
Physical VMEbus compatibility does not automatically guarantee functional compatibility. The host system, slot configuration, addressing, jumpers, and software should be verified.
Is it suitable for legacy-system maintenance?
Yes. The XVME-545 is particularly useful when maintaining or restoring older Xycom VMEbus-based industrial equipment.
