In an Airbus485 network, in order to establish communication between different controllers it is vital that each node (slave) has its unique address.
Airmaster products allow the user to configure the Airbus485 address - refer to the specific Airmaster product manual for a detailed description on how to configure the Airbus485 address.
Metacentre Master Controllers & Metacentre IO boxes have a fixed Airbus485 address that cannot be configured.
For a list of Metacentre Unit Airbus485 addresses, download the Modbus RTU Airmaster Metacentre manual and refer to page 17 - 2. Metacentre System Network Addresses
