1.2 Connect the second module
If you have two modules in the same RS-485 network and both modules have the same address
and baud rate; they will conflict with each other.
Because the factory default setting for each module has the same address and baud rate
(address=01, baud rate=9600), the user must change the “Configuration Setting”. Double click on
the module ID listed in the information window of the 7000 U tility. Reconfigure the address
settings for each module as added to prevent a conflict. For example, to add the second module,
the user must change the address of the first module to 0x02 and then click the button “Setting”
(Figure 1-6).
Figure 1-6. Changing the Configuration Setting.
The configuration setting of the first module is: Address : 0x02 Baudrate : 9600 Checksum :
disable.
The configuration setting of the second module is: (factory default setting)
Address : 0x01 Baudrate : 9600 Checksum : disable
Now the user can connect the second module as in Figure 1-7.
