Selection Guide
Use the following criteria to select the correct communication board for your system:
- Step 1 – Identify your control system: Confirm Mark IV (DS3800 series) vs. Mark V/VI
- Step 2 – Check the revision suffix: 1A1A, 1A1B, 1A1C – each may have different hardware features
- Step 3 – Verify slot position: Confirm the board’s designated slot in your turbine control rack
- Step 4 – Confirm communication channel count: Single vs. dual channel requirements
- Step 5 – Check firmware version: Ensure board revision is compatible with your existing firmware baseline
