Make sure that your camera is selected. 

5.

 

Under 

Upload Firmware File,

 click the 

Get From Web

 button, or navigate to 

https://diffractionlimited.com/aluma-fpga-firmware/

 and download the 

latest FPGA firmware for your camera. 

6.

 

Under 

Upload Firmware File

 click the 

Choose File 

…

 button. 

7.

 

Browse to the firmware file you downloaded, and click 

OK

. 

8.

 

Confirm the upload process in any pop-up dialogs. 

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. 

NOTE: 

DL Config ships with a "factory file" that can be used in place of a specified 
firmware in the event of an emergency. If you need to restore your camera's 

firmware using that file, click the 

Use Factory File

 button in DL Config. This file 

is updated with every release of DL Config, and may not be the latest, 
depending on which version of DL Config you have installed.
