Figure 9.4 Practical application diagram of chrysanthemum connection
Figure 9.5 shows the start connection diagram. When this connection mode is adopted, the two
devices that are farthest away from each other on the line must be connected with a terminal resistor
(in this figure, the two devices are devices 1# and 15#).
