Upgrade by Substitution
- Effective and efficient
- Direct replacement of PCAs
- Exact size and mounting
- Use same connectors
- Retain chassis wiring
- Retain Power supplies
- Maintain system layout
- Maintain system familiarity
- Direct replacement of system PC
- Powerful processor

- Joystick and Pilot primary controls panel
- Tooling and secondary controls panel
- Touchscreen simplicity
- Rapid installation
- Pre assembled replacement consoles attach to existing fittings
- Controls by USB connection to PC Hub
- ROV PCA set substituted in a few hours
- Only five working days installation, setup, testing and training
Benefits of Upgrade by Substitution
- Increased reliability by reduction of risk elements
- Control Room – 1000+ pin contact connections reduced to <50
- ROV Control Can – 1000+ pin contact connections reduced to <50
- Survey Can – Ethernet & HD Video Options
- CAN Bus benefits
- Each PCA is a Node on the CAN Bus
- Each PCA Reports Status of outputs
- Each PCA has supply rail monitoring
- Each PCA monitors current drawn on each output channel
- Extensive diagnostic capabilities
- Status messages for PCA health
- Feedback messages confirm output fidelity to surface controls
- Multiple pages
- Supply rail monitoring on every Node
- Output Signal confirmation
- Output current monitoring
- Dropped node awareness
- Ease of expansion & adaptation
- CAN bus connectivity on all nodes
- Customer specified functionality determines number of nodes
- Duplicate board types uniquely addressable
- Modular design allows customer specific interfaces to be incorporated
Upgrade by Substitution
