RS-485 Network Configuration – BACnet
Figure 29: BACnet Option
Select BACnet, to access the BACnet pull down menus.
Select the BAUD rate to match other devices on the network.
BACnet Device Name can be set to help identify this device and location.
BACnet Device ID ( Incidence #) is a unique number to identifies this device on the network.
Typically, the first part of the number is the same network #, and the last two characters are the same as the Address.
This is not a requirement, but can help in system planning.
