Replacing all electronics

Randy,

The following items will need to be corrected within your diagram:
- An E22158 SeaTalk to SeaTalkng Converter will need to be installed as a component within your SeaTalkng Backbone to accommodate the legacy devices within your system having a SeaTalk communications interface (i.e. the ST60 Instrument listed within your diagram
- The ST60 Instrument will not be connected to the i70 as is shown within your diagram. Instead, it will be interfaced to the yellow SeaTalk socket of the aforementioned SeaTalk to SeaTalkng Converter
- The 12VDC power insertion point for the SeaTalkng backbone should be located at the approximate mid-point of the SeaTalkng backbone's LEN load.
- Should the iTC-5 be located at the end of the SeaTalkng backbone as shown within your diagram, then a SeaTalkng Termination Plug will need to be installed within the unused blue backbone socket of the iTC-5.
- The SeaTalkng backbone may not be interfaced to the HS5 RayNet Network Switch as is shown within your diagram. Instead, the system's Data Master MFD (i.e. that which will always be switched ON when the system is in use, will be interfaced as a spur to the SeaTalkng backbone. Also, as your concept of operation calls for operation of either MFD while other MFD is switched OFF, then each MFD will need to function as the system's Data Master MFD. Correspondingly, each MFD will need to be interfaced as a spur to the SeaTalkng backbone.
