IS200UCVBG1A | 24V UCVB Communication Module

Description

Product Introduction (Anti-Template)

The brains of a Mark VIe system don’t work without the bus that connects them—and this board is a key part of that communication backbone. The IS200UCVBG1A is the UCVB (Universal Communication VME Bus) variant for the Mark VIe system, a controller board designed for high-speed data communication between system modules. This board handles the data transfer between processor modules, I/O modules, and other system components.

The ‘G1A’ designation indicates a specific variant with the ‘A’ revision. The UCVB is a critical component in the Mark VIe architecture, providing the bus interface that enables coordinated control. The ‘A’ revision brings improved communication reliability and updated firmware. Compared to the base IS200UCVBG1, the ‘A’ offers better data throughput stability. This board is a drop-in replacement for the IS200UCVBG1, with no software changes required.

⚠️ Software Compatible: IS200UCVCH1A — Different UCV variant. Verify compatibility with your specific system configuration before substituting.

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

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

Frequently Asked Questions (FAQ)

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

A: The UCVB provides the VME bus communication interface between Mark VIe system modules, enabling data transfer between processor modules, I/O modules, and other system components. It’s a critical part of the system communication backbone.

Q: What improvements does the ‘A’ revision have over the base UCVBG1?

A: The ‘A’ revision has improved communication reliability and better data throughput stability. Firmware updates may also be included.

Q: Can I replace a UCVBG1 board with a UCVBG1A without any changes?

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

Q: Is the UCVB 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 UCVB board?

A: Standard communication controller protocol. First, visual inspection. Second, verify continuity on backplane connectors. Third, power up and verify communication with other modules. Fourth, run diagnostic tests to verify data throughput.

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

A: Check component markings against GE documentation. Weigh the board; should be about 350 grams. Look for the GE holographic security label.

Q: Where do I find the official documentation for the UCVBG1A?

A: GE document GEI-100600 series covers the UCVB communication boards. The G1 variant is detailed in the section specific to that configuration. Always cross-reference against your system documentation.
