What to do if instrument data is unavailable on Raymarine Marine Equipment displays?

If instrument, engine, or other system data isn't showing on any Raymarine Marine Equipment displays, start by checking the data bus wiring and connections to ensure they are properly connected. Also, verify the overall integrity of the data bus wiring. Confirm that the source of the missing data, such as an ST70 instrument or engine interface, is operational. Check the power to the SeaTalk bus. If these steps don't resolve the issue, there may be a software mismatch and you should contact Raymarine technical support.
