▲Q:I want to install a set of satellite reception equipment, but I do not know what all need?
Answer:A set of satellite reception equipment is composed of a receiver, a dish antenna (commonly known as a pot), a high-frequency head and a coaxial cable connection.
▲Q:Are satellite receivers all the same?
Answer:Satellite receivers can be divided into analog and digital two categories according to the type of received signal, at present basically are digital receivers; according to the reception of the program can be divided into free receivers and conditions of the receiver (commonly known as card machine); conditions of the receiver according to the encryption of the applicable program can be divided into several categories, such as single-system card or dual-system card machine, VIACCESS card or IRDETO card machine, and so on. IRDETO card machine, etc.
▲Q: What is the difference between a free receiver and a card reader?
Answer:This is very simple, a card player has at least one slot where you can insert a card. Moreover, free receivers are usually sold in the home appliance market, while card players are rarely sold publicly.
▲Q: The bigger the pot, the more programs I get?
Answer:It's not wrong to say that for the same type of pot. However, the number of programs is determined by the satellites you are receiving, and with a smaller pot, some of the programs with weaker signals may not be received. If all the programs are already stable, a bigger pot would only be a waste.
Answer:This is a question I would like to know, and there is no answer. If you want to know very much, then ask the satellite program broadcasters to see when they will change the system.
▲Q:How to set the 0/22k switch when I use AeroTech 430XP to receive 146 and 76.5 stars?
Answer:To use two systems to receive 146 and 76.5 with 420, you can set them separately. First enter a system, in the antenna settings, select the two input TONE BURST, at the same time to set the local oscillator to dual local oscillator, respectively, enter the same local oscillator number of the HF head can be. Then set up in another system according to the above method, you can receive the corresponding program when switching systems. With this method, the two antennas and 22K switch connection method is not restricted, the interface is randomly selected.
▲Q: 430 machine suddenly can not receive encrypted programs, only free programs, why?
Answer:Please check if there is something wrong with the card or card slot. In addition, if you are not sure if you have the right type of program, please click the right button of the remote control to see if you can change it back. ▲Q:430 machine remote control does not work how to do?
Answer:Open the remote control shell, the amplifier transistor S8050 EC pole change over (i.e., E-> C, C-> E, the middle of the B-pole is unchanged, it is best to R3 parallel connection of a 2 ohm resistor.
▲Q:Can one antenna be connected to two receivers?
Answer:Yes,you can use double principal oscillator C-band HF head when receiving C-band,otherwise,the two machines can only receive the same polarization program. Satellite TV signals are divided into two ways: vertical plan and horizontal polarization, which are controlled by the receiver by changing the voltage. If two receivers receive programs of different polarizations there will be a conflict and they cannot be viewed properly. With a dual principal oscillator C-head, different polarization methods can be controlled with different principal oscillators. There are two ways to connect two receivers with one antenna; one is to use the power splitter to split the signal into two ways and send it to two machines, and the other is to connect the second machine to the signal output port of the first machine.
▲Q: What is ALLCAM system?
Answer:ALLCAM originally referred to the Multi-System Module, which is compatible with multiple encryption systems at the same time.ALLCAM system combines the functions of the Multi-System Module with the system software of the machine to achieve the purpose of viewing multiple encryption systems at the same time. Currently, ALLCAM system is mostly used in XSAT4X0 series, which can watch more than five encryption system programs with one 877 card.
