The S4 Open BACnet-N2 Router supports communication with any N2 device on an N2 bus, including direct read, write, override, and release transactions. It enables co-existence with Metasys head ends and facilitates integration of N2 devices into BACnet through automatic discovery and configuration. The router also exposes all points from N2 devices to the new head end, resets devices when operations fail, and provides a cost effective gateway to migrate legacy N2 systems to BACnet over time.
