A system can only be successful when the components of various manufacturers function with one another without problems. EUTELSAT manages a library of components from all manufacturers, so that all possible combinations can be adjusted. In addition, all manufacturers of DiSEqC components have a "DiSEqC reference test tool", with which all systems parameters can be tested. In the case of an occurring incompatibility despite these measures, all manufacturers using the protected DiSEqC logo are obligated to correct this on a practical technical level.
