The FC Bus terminal block is a blue, removable, 4-terminal plug that fits into a board-mounted jack. Wire the removable FC bus terminal block plugs on the controller that is on the top row of the stacked connector, and wire the other field controllers in a daisy-chain configuration using 3-wire twisted, shielded cable as shown in Figure 1. See Table 1 for more information.
