SeatTalk 1 to SeaTalk ng Converter LED Light will not Illuminate after Upgrading

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Keith,

It is quite possible that the SeaTalk to SeaTalkng Converter is not receiving power from the backbone. As such, it is recommended to that the backbone cable connecting the 5-Way Connector to the ST-STng Converter be disconnected and re-seated in the 5-Way Connector. The ST-STng Converter end of the Backbone Cable should then be tested for power using the information found here. If power is present, then the backbone cable should be connected to the ST-STng Converter and the locking collars of the 5-Way Connector and ST-STng Converter be rotated into the locked position to lock the backbone cable in place. Should the problem persist thereafter, then it would be recommended that the ST-STng Converter be sent to Raymarine’s Product Repair Center to be bench tested/serviced.
