Setting The Address - Interflex IF-800/W02 Manual

8 Setting the Address

An address must be set for identification.
Address setting for the connection to a terminal controller or an access manager:
It is common practice to assign the first slave terminal on each RS485 BUS to address 1, the second to
address 2, and so on.
Address setting for the connection to a master terminal:
It is common practice to assign the first slave terminal to address 2, the second to address 3, and so on.
Before making the settings, check the BUS address section of the higher-ranking device, such as, e.g., a
master terminal. You can do so by using a remote program, e.g. Telnet, and entering the OC command "cfg".
Furthermore, please check if the address of the terminal already exists on this BUS. It is not allowed to
assign identical addresses to one RS485 BUS.
Switch off the power supply prior to changing an address.
