BACnet/SC Node

The hub relays all messages to the network devices. All BACnet/SC-enabled devices besides the hub are nodes and are required to make a connection to the primary hub. To do so, they have to provide proper digital certificates to the hub (and the hub to the devices). Once the hub authenticates the devices, they can send messages through the hub, using encrypted payloads. There is a limit to how many nodes can connect to a hub-capable device.
