Warning
Never upgrade the firmware of a device connected through a USB Hub, including the Hub on the back of OGMA cooled cameras, because it could damage the firmware of the Hub device.
Always connect the device you want to update directly to the computer before running a firmware update.
For added safety, consider removing all other USB devices from your computer while applying a firmware update.
Firmware Files
Identify Your Filter Wheel and Download
There are three circuit versions of the filter wheel. To ensure proper operation, select the correct firmware that matches your circuit version before flashing it. Refer to the following images when checking your filter wheel's internal layout.
Flashing the wrong firmware may cause incorrect positioning or failure to detect filters.
Reflective Sensor
The infrared sensor and emitter are mounted on the same side of the circuit board, using a reflective detection method.
Transmissive Sensor
The infrared emitter and sensor are mounted on opposite sides of the carousel, using a transmissive (through-beam) detection method.
OpenOGMA
This is the green circuit with the OpenOGMA logo.
The files above are compressed archives. You have to extract their content before flashing the firmware.
The Zip files for the reflective and transmissive versions contain:
A video tutorial in MP4 format to guide you through the steps to update the firmware.
A flashing tool named updatefw.exe.
A dynamic library named ogmacam.dll is necessary to communicate with your device.
The actual firmware file that will be flashed has a file extension .icc.
The Zip file for the OpenOGMA version contain:
A flashing executable tool
The actual firmware file with the extension .uf2
After applying a firmware update, it is a good practice to disconnect the USB cable and wait 30 seconds before reconnecting it.
Addressed Issues
Without this update, in some rare instances, the filter wheel may lose track of its position.
