Frequently Asked Questions (FAQ)

1. What is the difference between IS215UCVDH7 and IS215UCVDH7AM?

The AM variant carries two functional revisions: 1A and 2M. The parent H7 board typically carries a single revision. The AM version also includes specific component updates verified during Salem production.

2. Can I use the mouse, keyboard, and monitor ports?

No. GE designates these ports for factory use only. They do not function as standard peripheral interfaces in the field. Use COM1 and COM2 for setup and serial tasks.

3. What do the ten H/L runtime LEDs tell me?

They display numeric error codes. Each H/L combination represents a specific runtime fault. Refer to GEH-6721 manual series for code translation.

4. Is the ISBus Drive LAN port required for operation?

No. Original GE documentation states these ports remain unused. You do not need to connect them. The ethernet port handles all UDH communications.

5. How do I verify conformal coating integrity?

Perform a visual inspection under bright light. The coating should appear uniform and glossy. No bare pads or lifted areas. No flaking or peeling at connector edges.

6. Buying advice: Should I choose the H7AM revision over older UCVD boards?

Yes. The IS215UCVDH7AM includes both revision A and M updates. It is the most current UCVD variant for Mark VI systems. It resolves known issues from early H7 production runs. Always verify your system group compatibility, but this board suits most Mark VI turbine retrofit projects.
