IS200VCMIH2B | New Surplus GE VCMI PCB

Description

Product Introduction (Anti-Template)

When you need both high communication throughput and the latest reliability improvements, the H2B variant delivers on both counts. The IS200VCMIH2B is the revision B variant of the high-throughput VCMI series, combining the enhanced data throughput of the H2 variant with the reliability improvements of the ‘B’ revision. This board handles critical communication between processor modules, I/O modules, and the system bus with higher throughput and improved management.

What does the H2B variant deliver? The H2 offers higher throughput than the H1 variant, and the ‘B’ revision brings improved data throughput stability, enhanced bus management, and updated firmware. Compared to the IS200VCMIH2A, the ‘B’ offers better performance under heavy bus load and improved reliability. This board is a drop-in replacement for the IS200VCMIH2A, with no software changes required.

Frequently Asked Questions (FAQ)

Q: What’s the difference between the H1 and H2 variants?

A: The H2 variant offers higher communication throughput than the H1, making it suitable for applications with more demanding data transfer requirements.

Q: What improvements does the ‘B’ revision have over the ‘A’ for the H2 variant?

A: The ‘B’ revision has enhanced throughput stability, improved bus management, and updated firmware for better performance under heavy bus load and improved reliability.

Q: Can I replace a VCMIH2A board with a VCMIH2B without any changes?

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

Q: Is the VCMIH2B 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 VCMIH2B?

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 enhanced throughput.

Q: How do I verify I’m getting a genuine VCMIH2B?

A: Check component markings against GE documentation. Weigh the board; should be about 354 grams. Look for the GE holographic security label.

Q: Where do I find the official documentation for the VCMIH2B?

A: GE document GEI-100660 series covers the VCMI communication boards. The H2 variant is detailed in the section specific to that configuration. Always cross-reference against your system documentation.
