RL70C not communicating with RC631

dkritter,

Based upon the symptoms supplied, I suspect that the problem may be caused one of the following:
- poor electrical connections in the circuit supplying the SeaTalkng backbone
- batteries have deteriorated and are in need of replacement
- the battery capacity supplying the marine electronics either lacks sufficient capacity

It is correspondingly recommended that circuit supplying the SeaTalkng backbone be inspected from the SeaTalkng backbone's power cable through the power distribution panel to the batteries to ensure that all cables are of the appropriate gauge, free of corrosion, and connections are tight. If so, then it is recommended that the batteries be load tested and that you additionally consider additional battery capacity. With the exception of the 12VDC power feed to the SeaTalkng backbone, the diagram appears correct. Your diagram shows the SeaTalkng power insertion at one extreme end of the backbone, whereas our recommendations call for the SeaTalkng power insertion point to be at the approximate mid-point of the backbone's LEN load ... move the power insertion cable to the other side of your SeaTalk to SeaTalkng Converter. That said, it is very unlikely that SeaTalkng power insertion point's location is the source of your problem.
