Can I make the JCI Metasys N2 bus run faster?

The JCI design of the N2 bus is fixed at 9600 Bd. We have to live with that. It can’t be changed.

So, the problem becomes how do we accommodate BACnet IP or OPC transactions coming in at Ethernet speeds?

  • Transparent Caching and BACnet COV support improve efficiency

  • Validating the N2 bus, repairing any installation problems, and removing sources of electrical interference improve performance

  • Breaking the N2 bus into smaller segments distributes the load. Each segment may come into a separate Downstream N2 Interface on a N2 Router or each one come into a separate N2 Router

  • Poll rates may need to be adjusted to frequencies more realistic for the capabilities of the N2 bus
