Manufacturers of satellite receivers periodically release updates to the software of their equipment, fix errors in it, and improve performance or add some new features.
In order to update the device firmware, you must first download it to a personal computer, and then connect the receiver to a PC and restart the program. A null modem cable is used to connect the computer to the satellite signal receiver. If you do not have such an interface, it can be purchased at computer stores, however, these products are not always there. In any case, you have a choice: look for a ready-made solution or make a null-modem cable yourself. The latter option will cost much less.
