[CA] [CA11] C70 to Axiom 9 Upgrade

Brad,

RF suppression ferrites would not address the reported issue. Raymarine does not recommend installation of VHF radios within 3' of other electronics. However, a VHF radio which is not transmitting or switched OFF should have not impact upon nearby electronics (except devices designed to detect the earth's magnetic field (ex. EV-1 / EV-2 CCU, autopilot fluxgate compass, instrument compass, etc.). Should the vessel feature a hard top and/or the helm be constructed from metal, then GPS signal strength available to helm mounted GPS sensing devices will indeed be reduced. Should the vessel feature a Raystar 125 GPS Sensor, then it would be recommended that a second SeaTalk to SeaTalkng Converter (the VHF NMEA 0183 to STng Converter Kit and SeaTalk to SeaTalkng Converter Kit utilize the very same SeaTalk to SeaTalkng Converter). The second SeaTalk to SeaTalkng Converter would be connected to the first SeaTalk to SeaTalkng Converter via an appropriate length of SeaTalkng Backbone Cable (blue w/black stripe). As the current SeaTalkng / NMEA 2000 backbone is powered if properly installed, then SeaTalkng Power Cable supplied with the second SeaTalk to SeaTalkng Converter Kit will not be used.

The Raystar 125 GPS Sensor's Cable will be spliced to an appropriate length of SeaTalk Cable having a molded press-fit 3-pin plug. To do so,
- the RS125's red and green leads will be spliced to the red lead of the SeaTalk Cable
- the RS125's yellow lead will be spliced to the yellow lead of the SeaTalk Cable
- the RS125's brown & black/bare leads will be spliced to the shield/bare lead of the SeaTalk Cable
The cable assembly's molded press-fit 3-pin plug will be inserted into the socket of a D244 SeaTalk Junction block. The SeaTalk to SeaTalkng Converter Cable's molded press-fit 3-pin plug will also be connected to the aforementioned D244 SeaTalk Junction Block. Finally, SeaTalk to SeaTalkng Converter Cable's yellow plug will be connected to the color coded SeaTalk socket of the second SeaTalk to SeaTalkng Converter.
