Fig 1 RS485 physical connection in single application
10.3.1.2 Multi-application
In the real multi-application, the chrysanthemum connection and star connection are commonly used.
Chrysanthemum chain connection is required in the RS485 industrial fieldbus standards. The two
ends are connected to terminal resistors of 120Ω which is shown as figure 2. Figure 3 is the simplified
connection figure and figure 4 is the real application figure.
