Before attempting to upgrade the Flex to the current firmware, please read the following:

  • August 5, 2016 – There is a new update for all Flex models – Wifi, IP, and PoE.  This version of iHelp (4.93) will update Flex devices to a version number ending with -19. The update to version -19 contains no additional features, but fixes a minor bug that would cause the Flex with Flex Link Serial cables to lock up and become non-responsive. See the release notes (WiFi/IP) for more information.
  • If you use DHCP, the IP address may change during the upgrade process. You should make note of it for use in control apps or configuration.
  • If updating the Flex firmware while using Windows connected in Adhoc mode, Windows will not automatically reconnect to the Flex after it reboots, and iHelp will be unable to reconnect to finish the update (upload webpages).  Either reconnect Windows to the Flex Adhoc manually, or connect the Flex to a local network (Infrastructure mode) before starting the firmware update.
  • There is a known issue with updating earlier hardware revisions of the Flex. Before updating, please check the following conditions to ascertain if the Flex is compatible with the current firmware release.
    • If the PCB_PN number is -08 or earlier, the firmware is likely incompatible. iHelp should detect earlier hardware and prevent attempted updates.
    • Details iHelp menu Details PCB-PN top Details PCB-PN
    • Flex units with a gray enclosures likely have the non-compatible hardware.
    • PCB_PN numbers that end with -0A or -0B are compatible. During the update process, the number may change to -10, or -11. This is expected.
    • If the current firmware version ends in -03 this firmware anti-gray-flex.fwupgrade is not compatible with your hardware. Please do not attempt to update the device as it may become unusable. Contact for options if you need an updated firmware.
