SBIG Camera Firmware Updates

Updating your Camera’s Firmware

We release firmware updates to the Aluma, Aluma AC, STC, and StarChaser series cameras and guiders which can contain: bug-fixes, improvements, optimizations, and new features. We advise updating the DL Imaging suite simultaneously. You can update your FPGA firmware via the DL Config application as follows:

  1. Install the latest version of DL Config – this will also update your camera drivers
  2. Power up your camera and connect to the computer (USB recommended), but make sure it is not connected to MaxIm DL or other control software
  3. Download the latest firmware revision (below)
  4. Go to Start Menu / DL Config Utility and run the DL Config Utility
  5. Make sure your camera is selected
  6. Click the Firmware button
  7. Click the Browse button to locate the firmware file you downloaded
  8. Click Upload and confirm
  9. Wait until the process is completed.  Do not interrupt the process or it will revert to old firmware
  10. When complete, power down the camera and power it up again

For details on how to update your camera’s Wireless firmware, please review this document.

NOTE: Original Equipment Manufacturers with customized camera firmware should contact us for assistance. The firmware presented here is not for OEM use and is intended for end-users of standard product.

NOTE:  Users of SBIG STF, STX, and STXL series cameras should instead use the SBIG Driver Checker.
