GE IS215UCVDH5AN UCVD VME Control Video Display Board

Product Overview

The GE IS215UCVDH5AN, also cataloged as the IS215UCVD VME Control Video Display Board, operates as a dedicated hardware component for display interfacing and control data processing within the GE Mark VI Speedtronic turbine control system.

Hardware Specifications

Backplane Bus Communication and Firmware Flash Compatibility

The IS215UCVDH5AN utilizes the VMEbus protocol for deterministic backplane communication, maintaining synchronization with Mark VI control processors. Firmware flash compatibility is constrained to revisions explicitly validated in GEH-6421 documentation; mismatched firmware may result in boot failure or communication lockout. Processor-to-backplane data exchange operates at fixed timing cycles aligned with the Mark VI system scan rate.

Frequently Asked Questions

Q: Can the IS215UCVDH5AN be hot-swapped in a live VME rack?

A: No. Backplane power must be removed prior to insertion or removal to prevent electrical stress on the board’s bus interface circuitry.

Q: Does the DH5AN suffix alter firmware requirements compared to earlier revisions?

A: Yes. Each suffix may correspond to specific BIOS and FPGA configurations; verify against the installed Mark VI rack firmware version before replacement.

Q: What is the maximum backplane current load for this module?

A: Typical consumption is under 3 A at 5 VDC from the VME backplane supply.

Field Installation Guidelines

Install the IS215UCVDH5AN into an approved Mark VI VME rack slot as defined in the system mechanical layout. Ensure all guide rails are free of debris prior to insertion. Apply even pressure along the board edges during mating with the backplane connector to avoid pin deformation. Secure the front panel screws to maintain EMI shielding integrity. Verify that the rack cooling airflow path remains unobstructed after installation.
