Firmware Files
Identify Your Filter Wheel and Download
There are two circuit versions of the filter wheel. To ensure proper operation, ensure that you select the correct firmware that matches your circuit version before flashing it. Refer to the following images for reference 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.
These files above are compressed archives. You have to extract their content before flashing the firmware.
Every archive contains:
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 with file extension .icc.
After applying a firmware update, it is a good practice to disconnect the USB cable and wait 30 seconds before reconnecting it again.
Addressed Issues
Without this update, in some rare instances, the filter wheel may lose track of its position.
