If a Site Director is at Metasys Release 10.0 or later, you must pair all child NxEs also at Metasys Release 10.0 or later with the Site Director. After you pair an NxE with a Site Director, the two devices use unique credentials to authenticate communication between them. You can pair NxEs with a Site Director during a code download. For more information about device pairing, see Pair NxE with Site Director.

Note: Select Do not Pair child devices to choose not to pair during download. For example, you cannot pair child devices if the Site Director is offline. Unpaired NxEs are not able to communicate with a Site Director, but you can use SCT to complete the pairing process at a later time (see Pair NxE with Site Director). You can also pair devices through the Site Management Portal of a Site Director or engine. For more information, refer to the Metasys Site Management Portal Help (LIT-1201793).

To pair NxEs with a Site Director during a code Download, complete the following steps:

  1. In the top username and password fields, enter an administrator account user's credentials for the Site Director, and then click Test Login. If the log in is successful, Login ID is OK appears next to the Test Login button and in the Selected Action column.
  2. If the Selected Action column of the Device table shows Login ID is not OK for any device, complete the following steps:
    1. Select the device.
    2. Enter the username and password for that device's security database, and click Test Login. When the log in is successful, Login ID is OK appears next to the Test Login button, and in the Selected Action column for that device.
    Note: If Pairing not needed is shown in the Selected Action column, then the device is at a release earlier than Metasys Release 10.0, and does not need to be paired.
  3. Click Next.
Important: After you complete the code download, perform an upload for paired devices and the Site Director, and select the option to include security. This practice ensures that the SCT archive contains accurate, up-to-date security details. For more information, see Upload.
