Appendix E-4: BACnet: Setting Network_Number for more than one ProtoNode
on Subnet
For both BACnet MS/TP and BACnet/IP, if more than one ProtoNode is connected to the same
subnet, they must be assigned unique Network_Number values.
On the main Configuration Parameters screen, update the Network Number with the
network_nr field and click the Submit button. The default value is 50.
