The sensor bus terminal block is a brown, removable, 4-terminal plug that fits into a board-mounted jack.
Wire the removable sensor bus terminal block plugs on the lower port of the dual stacked connector to the controller, and other sensor bus devices in a daisy-chain configuration using a 4-wire twisted, shielded cable as shown in the following figure. See Table 1 for more information.
