IS200UCVDH1A | 24V UCVD VME Bus Controller

Description

Product Introduction (Anti-Template)

Communication is the nervous system of your Mark VIe control—and the UCVD board adds a layer of diagnostic intelligence to that communication backbone. The IS200UCVDH1A is the UCVD (Universal Communication VME Bus with Diagnostics) variant for the Mark VIe system, a controller board designed for high-speed data communication with built-in diagnostic capabilities. This board handles data transfer between system modules while providing real-time health monitoring of the communication paths.

The ‘H1A’ designation indicates a specific variant with the ‘A’ revision. The key differentiator of the UCVD series is its diagnostic features—LED indicators, error logging, and communication status monitoring that help troubleshoot bus issues. The ‘A’ revision brings improved diagnostic accuracy and updated firmware. Compared to the base IS200UCVDH1, the ‘A’ offers better fault detection and reporting. This board is a drop-in replacement for the IS200UCVDH1, with no software changes required.

Key Technical Specifications

Compatible Replacement Models

✅ Drop-in Replacement: IS200UCVDH1 — The base revision without the ‘A’ suffix. Identical pinout, mounting, and software interface. The ‘A’ revision has improved diagnostic accuracy and firmware updates. No software changes required.

⚠️ Software Compatible: IS200UCVBG1A — Similar communication board but without diagnostic features. Verify compatibility with your specific system configuration.

⚠️ Software Compatible: IS200TBCI1A — Not a communication controller. Not suitable.

❌ Hardware Incompatible: IS200TBQGH1A — Excitation termination board. Different application.

Frequently Asked Questions (FAQ)

Q: What is the UCVD board used for in a Mark VIe system?

A: The UCVD provides VME bus communication between system modules with built-in diagnostic capabilities—LED indicators, error logging, and communication status monitoring to help troubleshoot bus issues.

Q: What’s the difference between the UCVB and UCVD boards?

A: The UCVD adds diagnostic features that the UCVB lacks—LED status indicators, error logging, and communication health monitoring. The UCVB is a basic communication board; the UCVD adds diagnostic intelligence.

Q: What improvements does the ‘A’ revision have over the base UCVDH1?

A: The ‘A’ revision has improved diagnostic accuracy and updated firmware for better fault detection and reporting.

Q: Can I replace a UCVDH1 board with a UCVDH1A without any changes?

A: Yes. The ‘A’ is a drop-in replacement. No software changes, no wiring changes, no configuration changes.

Q: Is the UCVD board hot-swappable?

A: We advise against hot-swapping communication controller boards. Interrupting the system bus while the system is live can cause communication errors. Power down the cabinet segment before swapping.

Q: What bench testing should I do before installing a UCVD board?

A: Standard communication controller protocol with diagnostics verification. First, visual inspection. Second, verify continuity on backplane connectors. Third, power up and verify communication with other modules. Fourth, verify diagnostic LED states and error logging functionality.

Q: How do I verify I’m getting a genuine UCVD board?

A: Check component markings against GE documentation. Weigh the board; should be about 355 grams. Look for the GE holographic security label.

Q: Where do I find the official documentation for the UCVDH1A?

A: GE document GEI-100610 series covers the UCVD communication boards. The H1 variant is detailed in the section specific to that configuration. Always cross-reference against your system documentation.
