Hardware Specifications

Backplane Bus Communication Velocity and Deterministic Networks

• The GE IS215UCVEH2A utilizes a 300 MHz Intel Celeron processor to execute deterministic control loops and preserve backplane bus communication velocity across the VMEbus rack.
• Direct integration with the Mark VI VME backplane enables high-bandwidth data transfers between I/O packs, main processor slots, and network interfaces.
• High I/O density scaling and real-time task synchronization are maintained through dedicated hardware timers and onboard system memory controllers.
• Module firmware flash compatibility ensures synchronized operational sequencing and fault reporting across redundant controller configurations.

Frequently Asked Questions

Q: Can the IS215UCVEH2A controller card be hot-swapped while the VME rack is energized?

A: No, control power to the Mark VI VME rack assembly must be completely de-energized prior to removing or inserting the UCVE controller board to prevent bus disruption and hardware damage.

Q: How is the onboard 32 MB DRAM memory utilized during execution?

A: The onboard DRAM stores real-time control code, system operating variables, and communications buffer queues transferred via the VME backplane.

Field Installation Guidelines

Ensure that main power to the Mark VI rack cabinet is de-energized and locked out before initiating installation. Wear a grounded ESD wrist strap connected to a verified chassis ground point when handling the IS215UCVEH2A card. Slide the card into its assigned slot using the VME card guide tracks until the rear edge connectors align with the backplane. Firmly seat the card by engaging the top and bottom ejector levers simultaneously, then tighten the retaining screws to guarantee mechanical grounding and chassis stability. Reconnect all front-panel network and serial cables before reapplying system power.
