NOTE
If there are two instances of the same MAC address, it could
result in a network crash. The node offset will allow you to avoid
this situation.
2.4.2.1 Set Node_Offset to Assign Specific Device instances for BACnet
MS/TP and BACnet/IP
• If the Device Instances need to be set for addresses other than 1 to 255, change
the Node-Offset (See Figure 2-2)
• The BACnet Device Instance can range from 1 to 4,194,303.
• BACnet/IP and BACnet MS/TP Addressing: The BACnet device instances will
be set by taking the Node_Offset found in Web Configurator (see Figure 2-2)
and adding it to the value of the A Bank DIP switches. When more than one
device is connected to the ProtoNode, the subsequent BACnet device instances
will be sequential.
• Set the PC address to be on the same subnet as the ProtoNode. See section
5.3 on how to change the IP address. (See Figure 2-2)
• Open the PC browser to default IP address, which will bring you to the FST Web
Configurator for the ProtoNode.
• Change the Node offset to meet the required device instance.
For example:
o Node_Offset = 20000.
o A Bank DIP Switch = 11
o Device 1 Device Instance = 20011
NOTE
The A bank dip switch setting + node offset = device instance
setting.
