Another SeaTalk 1 system upgrade.

Bradley,

Your system diagram appears to indicated correctly interfaced equipment. It is recommended that:
- you verify that the X10's SeaTalkng power switch has been configured OFF to prevent a ground loop
- you verify that when Databoxes within the MFD has been configured to display the Heading (not COG) and Rudder data items, that the these items are indeed populated
- you verify that the autopilot control head display's Heading
- you verify that the MFD's Data Source's feature (HOME->SET-UP->SYSTEM SET-UP->SYSTEM SETTINGS->DATA SOURCES) has been configured to specify that the RS125 be used as the system's GPS data source. Alternatively, the MFD's internal GPS may be configured OFF. After doing so, the system should be switched OFF and then ON again to verify that the system is receiving a GPS position FIX from the RS125.

Should the above listed items have been satisfied, then it is recommended that the ST6001 be temporarily disconnected from the D244 SeaTalk Junction Block and it should installed be tested by connecting it directly to the x10's SeaTalk port.
