Use the BACnet/SC Management feature that is part of Metasys UI or JCT to set the communication mode.

To set the communication mode from the BACnet/SC Management window, complete the following steps:

  1. Wait about 30 seconds after the certificate import before you set the communication mode.
  2. Click the Devices tab, if it is not already open.
  3. Select one or more devices that you want to set the BACnet/IP communication mode for.
  4. Click ACTIONS > Set BACnet IP Communication Mode.
  5. Choose a mode for the selected devices and click APPLY.
Note: Setting the BACnet/IP communication mode can disrupt communication on your site and devices may go offline briefly. Expect some downtime when you set the BACnet/IP communication mode for your devices.
Note: It is best practice to first turn on Dual SC and IP Mode on targeted supervisory devices, then turn on Secure Connect Only Mode on equipment controllers. You can then optionally change supervisory devices to Secure Connect Only Mode if all devices that they interact with also communicate with Secure Connect Only.
The following table outlines the different communication modes.

Modes Definition Supported devices
Secure Connect Only Mode BACnet Secure Connect (BACnet/SC) is an addendum to the BACnet protocol. BACnet/SC is a secure, encrypted datalink layer for IP infrastructures.

Ethernet IP Only Mode BACnet/IP is a BACnet protocol that is used for installations where Ethernet cabling with a high-speed, industry standard open communication protocol is required and where BACnet/SC is not yet supported.

Dual SC and IP Mode Devices set to this mode can communicate through BACnet/SC to devices that support BACnet/SC and they can communicate through BACnet/IP to devices that support BACnet/IP only. OAS, NAE85, LCS85, SNE, SNC, and NAE55xx-3x
