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:
- Install the latest version of DL Config – this will also update your camera drivers
- 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
- Download the latest firmware revision (below)
- Go to Start Menu / DL Config Utility and run the DL Config Utility
- Make sure your camera is selected
- Click the Firmware button
- Click the Browse button to locate the firmware file you downloaded
- Click Upload and confirm
- Wait until the process is completed. Do not interrupt the process or it will revert to old firmware
- 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.

Aluma Firmware Revision 20
Revision 20 - 2019/10/29
+ Status LED now defaults to "ON" in Aluma firmware, pursuant to changes in revision 18.
Aluma Firmware Revision 4
Revision 4 - 2019/10/29
