Search for the connected module again. It will find two modules at address 0x01 and 0x02 as
shown in Figure 1-8.
Figure 1-8. Found Two Modules at 0x01 and 0x02.
To connect more modules in the same RS-485 network, you must change the address to prevent
conflict. For example, the user can change the address 0x01 of second module to address 0x03.
Now the module configuration would be as follows:
Module 1: Address:0x02
Baudrate: 9600 Checksum: disabled.
Module 2: Address:0x03 Baudrate: 9600 Checksum: disabled.
Next, connect the third module as shown in Figure 1-9. The configuration of the third module has
the factory setting as follows:
Module 3: Address:0x01
Baudrate: 9600 Checksum: disabled
The user can connect several modules one by one. The important thing is that the modules cannot
have the same address and baud rate concurrently in the same RS-485 network.
