Completely Factory Resetting Evolution

[Chuck - Raymarine - Moderator]

Keith,

Per the ST60 RAI manual, the rudder reference transducer should be interfaced to the autopilot course computer when used within a system featuring autopilot. When so installed, the ST60 RAI would repeat rudder data transmitted to the SeaTalk bus by the autopilot's course computer. The Evolution ACU will ignore all sources of rudder data except for that from an analog rudder reference transducer which has been interfaced to its rudder terminals. Connecting the rudder reference transducer to both the autopilot course computer and the ST60 RAI may result in potentiometer loading of the rudder reference transducer, causing the dithering that you had previously identified.

It appears that data rate of rudder data being bridged from SeaTalk to SeaTalkng via the SeaTalk to SeaTalkng Converter is too slow to permit the ST60 RAI to be of much use as a repeater. A problem report will be logged accordingly to seek correction of this problem within a future SeaTalk to SeaTalkng Converter software update.

Until such a correction is implemented, it is recommended that the SeaTalk Data lead (yellow) of the SeaTalk cable connecting the ST60 Rudder Angle Indicator to the SeaTalk bus be cut to break its data communications with the Raymarine system. The ST60 RAI will continue to be powered the SeaTalk bus (through the red and shield leads of the SeaTalk cable which is joining the ST60 RAI to the SeaTalk bus). The ST60 RAI may then be interfaced to dedicated rudder reference transducer to be installed on the rudder.
