[CA] [CA11] upgrading Raymarine system

[skidston]

Thank you Chuck. I responded to you after the * below and modified the attached diagram. Please review and comment.

Please note that a powered and properly terminated SeaTalkng / NMEA 2000 backbone features only two SeaTalkng Termination Plugs. One SeaTalkng Termination Plug will be installed within each of the backbone's two unoccupied backbone sockets found at the two opposite ends of the backbone.
*Noted, I made several changes including only 2 terminals.

A SeaTalk to SeaTalkng Converter will not be used within the system which you are building. The GA150's cable will be connected directly to the coaxial GPS antenna socket located on the MFD's Power/interface panel.
*Noted on both accounts. Moved GPS to connect to FD and removed the converter and replaced with Ts

The SeaTalkng T-Piece, SeaTalkng 5-Way Connectors, and iTC-5 will be daisy chained to one another via appropriate lengths of SeaTalkng backbone Cable.
*Noted, based on changes above and this comment these are now daisy chained

It is recommended that the SeaTalkng / NMEA 2000 backbone be powered from a dedicated, switched 12VDC power circuit which will be connected to a SeaTalkng Power Cable. The SeaTalkng Power Cable will be connected to a spur (white) socket which will be located at the approximate midpoint of the backbone's LEN load.
*Noted, I added 12vdc power and will use the existing switch with power relay

At the time of this response, it is recommended that a standard VHF antenna be used with the AIS700 rather than an antenna which has been tuned specifically for use with an AIS transceiver.
*Potential problem - the Shakespeare 5396-AIS Galaxy Little Giant AIS/VHF Antenna is already mounted at the top of the mast with LMR400 Ultraflex coax. I know I may not get some lower VHF channels. Any other problems?

Each p70S, the EV-1 CCU, the ACU400, each i70S, and the AIS700 will each be interfaced to a spur socket within the backbone via an appropriate length of SeaTalkng Spur Cable. The Axiom Pro RV MFD will be interfaced to a spur socket within the backbone via any of the following options:
- A06045 / 15.7in (0.4m) SeaTalkng Spur to DeviceNet (F)
- A06075 / 39.4in (1.0m) SeaTalkng Spur to DeviceNet (F)
- A06082 DeviceNet (F) to SeaTalkng (M) Adapter and an appropriate length of SeaTalkng Spur Cable
*Noted, I believe each device comes with the version of the noted cables that I can connect to the back bone.
