A Building Automation or monitoring device that has Native BACNet capability does not require any additional module, gateway or driver to communicate to other devices with the BACNet communication protocol. The ability to communicate via BACNet is built-in and the device should be able to communicate immediately when connected to a network with other BACNet devices. A device that is not native BACNet will require a gateway device, BACNet interface card or another module that will allow it to communicate with other BACNet devices in a network.
