Search for the connected module(s) again. Note the two modules at

address 0x01 and 0x02 that will be found. See Figure 1-2-3.

Figure 1-2-3. Found two modules at 0x01 and 0x02.

To connect more modules in the same RS-485 network, change the

address to prevent further conflict between modules. For example: change
the address 0x01 of the second module to address 0x03. Now the
configurations of the two modules are as follows:

Module 1: Address:0x02 Baud rate: 9600 Checksum: disabled
Module 2: Address:0x03 Baud rate: 9600 Checksum: disabled

Then connect the third module as in Figure 1-2-4. The configuration of

third module contains the following pre-sets:

Module 3: Address:0x01 Baud rate: 9600 Checksum: disabled

Users can connect several modules one-by-one with the above steps. The

important thing is that the

modules cannot have the same address and baud

rate currently used

in the same RS-485 network.
