S100 No Pilot

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Tom,

The reported issue may result from any of the following conditions:
- old software within the SeaTalk to SeaTalkng Converter or Evolution Autopilot ... update all Raymarine products with the latest available Raymarine product software updates
- the battery level has dropped below that which the S100 may communicate with the autopilot ... replace the S100's batteries with a fresh set of batteries
- the base station has been installed in a location affording it to receive marginal RF signal energy from the S100 ... consider relocating the base station to a location which is closer to the S100 and offers less RF interference between the S100 and the base station
- intermittent SeaTalk or SeaTalkng communications path ... check for proper termination of the SeaTalkng backbone; check that the backbone is power from a single power insertion spur positioned at the approximate midpoint of the backbone's LEN load; check that the SeaTalk bus is being exclusively powered by the SeaTalkng backbone via the SeaTalk to SeaTalkng Converter.
- more than one GPS source present within the backbone ... use the autopilot's or MFD's Data Sources feature to specify which GPS data source will be used by the system.

Should you have addressed the items specified above and should the problem persist, then it would be recommended that the base station and S100 be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
