Important Notes

  • The Skylight element: LX firmware is delivered in a consolidated file prefixed by “ACC”, e.g. This file contains the firmware for the GT, GX , LX and LT Performance Element products. It cannot be used with any other product.
  • IMPORTANT: Prior to upgrading the firmware on a unit where the History Buckets feature is enabled, certain precautions may need to be taken to prevent a loss of history data during the upgrade.
  • After upgrading to 7.9.1 or 7.9.2, the SCP is no longer able to send files, reporting the following error: Code = 3: URL using bad/illegal format or missing URL. This is due to a syntax change and customer needs to edit the URL after upgrading to 7.9.2 or 7.9.3.
    The URI generic syntax (in RFC 3986) consists of a hierarchical sequence of five components: URI = SCHEME ':' ['//' AUTHORITY] PATH ["?" QUERY] ["#" FRAGMENT]. In this, AUTHORITY = [USER_INFO "@"] HOST [":" PORT]. The AUTHORITY part and the PATH part are isolated by the slash ('/') character if the AUTHORITY exists.
