Postup zprovoznění pod Linuxem

Z www výrobce se stáhne Open Source driver a pomocí "make && make install" se provede kompilace a instalace. Zavede se vzniklý modul a nechá se "kudzu", aby provedl konfiguraci řadiče.
Pro ovládání je možné použít WEB GUI, GUI nebo CLI aplikace uveřejněné opět u výrobce. V případě použití CLI a RHEL je potřeba doinstalovat "compat-libstdc++-33" jinak aplikace spadne bez varování na ústa.
Detailní informace viz. .PDF soubory u výrobce.
