from the manufacturer’s technical support:
1. Connect the fan cartridge module to any source using a Mini-USB cable.
The fan cartridge module opens a flash drive.
2. Copy the
MODFAN.pfw
file onto the fan cartridge module without deleting the old one first (copy and overwrite).

The fan cartridge module starts automatically with the new firmware.
8.3.4 Updating the Firmware of Analog Add-on Modules
Analog audio add-on modules cannot be field-updated via Mini-USB interface or matrix. They need to be factory
programmed. However, a firmware update is usually not necessary. If you have any questions about updating add-on
modules, please contact the manufacturer's technical support.
