2.4 - Set MAC address, Device Instance, Node-ID
2.4.1 - Setting the MAC address
•
•
•
Note: Never set a BACnet MS/TP MAC Address from 128 to 255.
•
•
• When using Metasys N2 and Modbus/TCP, the A bank of DIP switches is disabled and not used. They should be set to OFF.

2.4.2 - Setting the Device Instance (Node-ID)
•
•
For example:
• Node_Oset default = 50,000
• Device 1 has a Modbus Node-ID of 1, Device 2 has a Modbus Node-ID of 2, Device 3 has a Modbus Node-ID of 3.
•
•
•
•
Note: When setting DIP switches, ensure power to the board is OFF.

•
•
•
•
•
•
•
• Device 1 has a Modbus Node-ID of 1, Device 2 has a Modbus Node-ID of 2, Device 3 has a Modbus Node-ID of 3.
• Device 1 - Device Instance = 20,001
• Device 2 - Device Instance = 20,002
• Device 3 - Device Instance = 20,003
Note: The Modbus Node address + Node_Oset = Device Instance setting
