Greg,

Q1. Would it be better/any different for me to insert power to the backbone at one of the 5 way blocks ? One block I planned to place a meter cable away from the ITC-5, the other a meter cable from the MFD/displays. Don't have another midpoint really.
A1. When locating the power insertion point, the length of the backbone is not of consideration. Instead, it it the backbone's LEN loading which is of concern. When determining the midpoint of the backbone's LEN load, please refer to the previously referenced FAQ for LEN loading of each device. In a smaller backbone (i.e. the number of devices within the backbone) it is less important the the power insertion point be so located. It is possible to use the spur socket of a T-Piece, 5-Way Connector, iTC-5, or SeaTalk to SeaTalkng Converter to serve as the backbone's power insertion point.
