Would you connect multiple receivers in the same dish that you can using a multi-switch. With the improved multi-switch, it is possible for even a complete building of satellite-equipped TV. These installations are also often referred to as GSO (Joint Satellite Entertainment) Although this seems very complicated, it is in practice with giant. Some line diagrams how a multi-switch can be connected.
Universal Satellites Automatic Location System (USALS), also known (unofficially) as DiSEqC 1.3, Go X or Go to XX is a satellite motor protocol that automatically creates a list of available satellite positions in a motorised satellite dish setup. It is used in conjunction with the DiSEqC 1.2 protocol. It was developed by STAB, an Italian motor manufacturer, who still make the majority of USALS compatible motors.
DiSEqC is een afkorting voor Digital Satellite Equipment Control. Het is een systeem dat bedacht is door Eutelsat, die nogal eens te horen kregen dat hun Hotbird satellieten alleen met een ingewikkelde draaibare installatie te ontvangen zouden zijn door de mensen die naar Astra (hun grootste concurrent) keken.Je kunt met dit systeem vanuit de satellietontvanger zaken buiten bij de LNB sturen.
