DiSEqC......

DiSEqC is a standard established by the European organization Eutelsat satellites; it was (and still is , because it evolves ) defined in partnership with satellite reception equipment manufacturers (terminals, switches , motors) . From the moment this standard , which can be described as universal , received their approval , it should be not only adopted but above all respected by all ; Unfortunately , as evidenced by our tests with these engines , we are still far away : we are in a situation identical to that which existed at the onset of the DiSEqC switch boxes : we had to buy the right housing with the right receiver

DiSEqC 1.2

Logo 1.2The DiSEqC DiSEqC (Digital Satellite Equipment Control) is a trademark of Eutelsat, but remains an open standard recognized by the industry. This is a bus (digital command signal) carried by the coaxial antenna cable to equipment (switches, motors) which uses the presence of 22 kHz by sending "burst" composed of "words or basic messages "that are the bit" 0 "and" 1 "bit. Each specific command, or "Control Byte" is made up of these basic bits 0 and 1; we only deal with orders Bytes reserved for DiSEqC 1.2 antenna motor. New orders are standardized, more dedicated to the DiSEqC 2.2. Know that the DiSEqC 1.2 is a unidirectional bus, that is to say that for sending the orders only from the terminal to the equipment: it is its weakness. DiSEqC 2.2 allows the same commands but with feedback information: he himself is bidirectional, but its implementation is more difficult and consequently generates higher production costs?.!
