[CA] [CA11] upgrading Raymarine system

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum skidston,

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.

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.

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.

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.

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.

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
