Release notes & downloadShow release notes Hide release notes
Combined Control Box and Lamp Head firmware updates over USB and Bluetooth, a Maximum Power DMX control channel, and fan, NFC, and error display fixes. This update is delivered as a USB upgrade file. See Update Firmware via a USB Flash Drive for the procedure.
New Features
- USB Combined Firmware Upgrade. Added support for upgrading the combined Control Box + Lamp Head firmware over USB. When the USB drive contains both combined and separate firmware files, the combined firmware is upgraded first.
- Bluetooth OTA Combined Firmware Upgrade. Added Bluetooth OTA upgrade support for the combined Control Box + Lamp Head firmware. Upgrading the Control Box firmware on its own is no longer supported.
- Maximum Power on the DMX Control Channel. The DMX control channel now includes a function to set maximum power. The setting is applied even while DMX data is changing dynamically.
Enhancements
- Factory Reset xy Defaults. Changed the factory reset default x and y coordinates from (0.3301, 0.3390) to (0.4234, 0.3989).
- Corrected INT Label. Removed the space between I and N so the brightness label reads INT.
- Corrected xy Label. Removed the space between x and y and set both letters to lowercase on all related entries.
- Merged Version Display. Firmware version and hardware version are now shown on a single page.
- Quieter Error Reporting. When a general error occurs, the pop-up window no longer appears. Instead a warning icon is shown in the title bar, a red dot appears on the error code menu item, and the indicator light remains green on both the Control Box and the Lamp Head.
Bug Fixes
- NFC DMX Configuration. Fixed an issue where the interface refreshed after configuring the DMX profile and DMX address over NFC, but the actual control did not take effect.
- Control Channel Commands and Signal Flash. Fixed an issue where, when using the Control function in Sidus Link Pro, enabling signal flash would flash six times while the control channel itself did not function.
- DMX Fan Smart Mode After Power On. Fixed an issue where the DMX fan Smart mode would not respond after each system power on.
- Fan Mode on Channel Re-Enable. Fixed an issue where re-enabling the fan control channel maintained the current fan mode instead of setting the fan mode from the current DMX fan channel value.
- Fan Smart Mode Temperature Tracking. Fixed an issue where the fan speed in Smart mode did not adjust with temperature changes.
- EH.10 Error Display. Fixed an issue where EH.10 would continuously occupy the top of the screen and prevent switching to other error screens when it occurred alongside other errors.
- Bluetooth CCT and HSIC+ Range Limits. Fixed an issue where, under Bluetooth control in CCT and HSIC+ normal light modes, range limiting was not synchronized with the Control Box interface when processing G/M parameters. Also fixed an issue where image data display could be abnormal on the CCT interface.
- Memory Management. Unified dynamic memory management and fixed an occasional firmware crash when repeatedly plugging and unplugging AC.

Summary of the Updates to STORM XT52 This update must be done on USB. It cannot yet be updated over Sidus Link or Sidus Link Pro.
New Features
- Added coarse and fine adjustment modes for HUE and SAT parameters in HSIC+ mode, with UI switching between adjustment resolutions. Press and hold the Encoder Wheel on a parameter to Change Between Coarse Control with XX% and Fine Control XX.X%.
- Added expanded manual fan mode options, including Smart, Full Speed, High Speed, Medium Speed, Low Speed, and Silent modes.
Improvements
- Added new folder structure for DMX Profiles.
- Improved error detail reporting across multiple error codes, allowing clearer identification of error types directly on the fixture UI.
- Improved DMX and CRMX interface handling so the fixture reliably redirects to the correct DMX Status screen when DMX or CRMX data is detected.
- Improved DMX smooth fade-in and fade-out behavior for more consistent transitions.
- Updated DMX profile naming to align with the latest DMX profile requirements and improve readability.
- Improved real-time UI refresh behavior when changing DMX Profiles or DMX Address after Bluetooth auto-configuration.
- Improved indicator light logic so ignoring a general error restores the indicator light to green when no other errors are present.
- Improved temperature display layout and error presentation on the status interface.
- Improved Silent fan mode behavior, with Silent mode power fixed at 600 W and independent of maximum power settings.
- Improved performance in Sidus Link and Sidus Link Pro for PRO and GO programming, including responsiveness of HSI lighting effects.
- Improved performance of DMX static color mixing, FX lighting effects, and DMX Strobe behavior.
- Improved handling of general and minor error conditions so non-critical errors do not interrupt normal operation.
Bug Fixes
- Fixed Strobe function on DMX Control Channel Profiles.
- Fixed an issue where, after a factory reset and CRMX connection, entering CCT mode would not redirect to the DMX Status screen when CRMX data was present.
- Fixed an issue where CRMX could stop responding after being toggled off and back on.
- Fixed an issue where enabling or disabling DMX signal flashing did not take effect immediately.
- Fixed an issue where the interface did not refresh in real time after modifying DMX Profile or DMX Address following Sidus Link Pro Auto-Patching.
- Fixed an issue where the fixture could enter the control settings interface instead of the Bluetooth reset interface when deleting a device in Sidus Link.
- Fixed an issue where DMX Profile names could display incorrectly after Sidus Link Pro Auto Patching when selecting profiles 101 or higher.
- Fixed an issue where the network cable icon could remain visible after performing a factory reset with a network cable inserted.
- Fixed an issue where DMX zero-brightness data was not consistently honored under certain conditions.
- Fixed fan stall detection timing so fan failure errors are reported correctly after sustained stall conditions.
- Fixed pump error detection behavior to better distinguish pump stall and dry-run conditions.
- Fixed Fresnel behavior so the Fresnel correctly stops when power is off and resumes when power is on.
Known Issue
- DMX Control Channel must be activated for 3 seconds in this version and may produce an additional 3 flashes. This will be fixed in a future version.
