S2/SHS Problem

[Chuck - Raymarine - Moderator]

Q1: Has something changed to invalidate my initial design?
A2: You earlier diagram did not include the wireless autopilot controller's base station. Unlike the software of the E-Series Classic MFDs, the SeaTalk to SeaTalkng Converter's software has continued to be updated, making it the most complete and effective device for bridging data, especially that from autopilot products, from SeaTalk to SeaTalkng. Accordingly, the E-Series Classic MFD would be treated as a device having only a SeaTalkng port rather than both a SeaTalk and SeaTalkng port. Hence, the it was directed that the MFD be disconnected from the SeaTalk bus.

Q2: Is buying the SeaTalk to SeaTalkng Converter the only solution, or just a best practice?
A1: See the response to Q1.

Q3: Are there other solutions short of buying this additional equipment that "may" work, subject to testing?
A3: While other methods, such as that you have suggested, may support most functions, they are not supported, as they are incomplete solutions. The correct method of interfacing these products is as has been covered within these last two responses.
