Use the BACnet/SC Management feature that is part of Metasys UI or Johnson Controls System Configuration Tool (JCT) to manage your certificates.

The Importing Signing Certificate action is primarily used if there is a change to the CA that has signed certificates for an existing site. Before you import any certificates signed by the new CA, you first need to add the new CA to all devices on the site so that the devices can trust communicating with any devices that have been switched to use the new CA.
Note: Importing the signing certificate first is optional, if you are adding certificates to devices that are currently talking BACnet/IP, because none of the devices are talking BACnet/SC yet. The step to import the operational certificate automatically adds the CA first, if it is not already present on the device.

To import the signing certificate from the BACnet/SC Management window, complete the following steps:

  1. Click the Devices tab, if it is not already open.
  2. Select one or more devices that you want to import a signing certificate for.
    Note: You can select a maximum of 50 devices at a time.
  3. Click ACTIONS > Import Signing Certificate.
  4. Click Choose File and go to the .pem file that you want to import.
  5. Confirm that the file is from a trusted source and click IMPORT AND APPLY.
