VME Backplane and Control Processing
The IS415UCVGH1A operates as a VMEbus controller within the Mark VI/Mark VIe architecture. It uses the VME64 backplane to exchange control and I/O data with installed modules. The Intel Celeron processor executes the QNX-based control environment, while the SDRAM provides working memory for runtime processing.
The two 10/100BaseTX Ethernet interfaces support external network communication. In addition, the RS-232 port provides a local interface for diagnostic and setup functions. The VGA and PS/2 interfaces support local maintenance access where the system configuration permits.
GE Mark VI control hardware uses defined backplane communication paths for rack-level data exchange. Therefore, installation must match the controller type, rack configuration, and system software requirements.
Frequently Asked Questions
Q: What backplane interface does the IS415UCVGH1A use?

A: The supplied specifications identify an Intel Ultra Low Voltage Celeron 650 MHz processor and a QNX real-time operating system.
Q: Does the card provide Ethernet communication?
A: Yes. The supplied specifications list two 10/100BaseTX Ethernet ports for network communication.
Field Installation Guidelines
Install the IS415UCVGH1A in the designated 6U VME rack position and secure the card using the rack’s mechanical retention hardware.
Before insertion, isolate the rack power and verify the backplane connector condition. Align the board with the correct card guides and avoid applying lateral force to the VME connector.
Verify the VME rack configuration, controller position, and installed firmware or system software requirements before commissioning. Connect Ethernet and serial cables according to the cabinet wiring plan.
Keep Ethernet, serial, and video cables separated from high-current switching conductors where practical. Maintain cabinet grounding and shielding practices specified by the Mark VI or Mark VIe system documentation.
After installation, verify the +5 VDC backplane supply, board startup status, Ethernet link status, and controller communication before placing the control system into normal operation.
