I have translated the page and left the information as it was in German.
However, I have two DM500 running Gemini 4.70, and the directories listed in the article do not match. The Gemini image does not have a /usr directory. The only writable directory is /var. As such, the oscam binary should be placed in /var/bin, the oscam_cam.sh script should be copied to /var/script, and the configuration files should go to /var/keys.
The script must be updated with the correct path for the binary. Replace /usr/bin/$CAMD_BIN with /var/bin/$CAMD_BIN.
