The N2 bus and N2 devices were not developed with the BACnet concept of a Priority Array. Therefore, each N2 command is executed as soon as it is presented to the N2 bus and is recognized by the target device.

However, BACnet expects devices to honor the Priority Array concept so the BACnet-N2 Router acts as a proxy for the N2 devices and emulates a Prority Array for them.

From the standpoint of a BACnet client or device wanting to talk to a N2 device via the BACnet-N2 Router it can utilize all features of a BACnet Priority Array.
