When watching satellite TV, the signal is received from one of the satellites. It goes to the converter, from which it is transmitted to the satellite receiver. If for any reason the user wants to receive a high-quality signal from several satellites, he must use a separate converter for each of them. However, only one of them can be connected to the receiver at the same time. DiSEqC is a switch that is connected between the converter and the receiver. He connects the converter from the desired satellite to view his programs.

For work, a coaxial cable is used. The signal, the converter supply voltage, and also the control tone signal are transmitted through it. The protocol provides for several levels of use, which are arranged hierarchically. If the device supports one of them, then it will also ensure the use of all downstream ones. Several versions of the standard are used, the most common of which is DiSEqC 1.0. This device contains a microcontroller and specialized software inside. These switches allow you to receive signals from multiple satellites using a single antenna.This increases the freedom of choice when watching programs.
How it works
The device is connected to a satellite receiver and several converters. Usually two or 4 satellite signal receivers are connected to DiSEqC. After connecting, the receiver is set up. When using more complex connection schemes, you can significantly increase the number of connected converters.
How the disk works [/ caption] The figure shows one of the options for such a connection. Converters are directly connected to two DiSEqC 1.0. These devices are connected to DiSEqC 1.1. Thus, the receiver can be connected to eight converters. When connecting the converter, ensure that the cable length does not exceed 3 m. Otherwise, the quality of the signal received by the receiver will deteriorate. During the connection procedure, you must turn off the power of the receiver in order to avoid the risk of damage.
What types of DiSEqC switches are on the market
DiSEqC 1.0 is the most common form. Such devices can be simultaneously connected to four satellite receivers.
Dysic 1.0 [/ caption] Using DiSEqC 1.1 allows increasing the number of connected devices to 16. This device can be directly connected to converters or work with other switches. It allows the connection of four DiSEqC 1.0 converters, each of which works with 4 converters.

It is used to accurately position the antenna to the broadcasting satellite. The switch can directly connect the converters. Some DiSEqC 1.2 models do not provide the ability to work with other converters.
There is DiSEqC 2.X, which provides the ability to receive confirmation when executing commands. In this way, the switch can obtain additional information about the devices associated with it.
The DiSEqC 3.X standard has the ability to conduct a dialogue with peripheral devices. This opportunity has not yet been fully exploited. In the future, it is planned to provide automatic configuration in this way.
How to connect correctly
Next, we will talk about connecting DiSEqC 1.0 to Amos, Hotbird and Astra satellites. After installing the antenna, it is necessary to ensure that the converters receive signals from the corresponding satellites. Then it is necessary to connect each converter to the corresponding DiSEqC connector.
DiSEqC connectors [/ caption] When the receiver is off, connect to the switch using a cable. To do this, use the appropriate DiSEqC connector. Then the receiver is turned on. Now you need to configure. For this, the receiver is connected to the corresponding connector of the television receiver. After turning on the TV, you need to go to the receiver settings. The parameter setting for the mentioned satellites will be shown. When the settings open, in the menu that appears, go to the “TV Channel Manager” section. Next, you need to go to the “Installation” subsection. Next, you need to do the following.
In the DiSEqC line, put the fraction 1/4. In it, the numerator is the number of the connector where the corresponding converter was connected, and the denominator is equal to the number of available connectors. Shown here are the parameters for the Astra satellite. Next, Hotbird is configured, the cable from which is connected to the second port.
The DiSEqC parameter will be 2/4. The Amos satellite was connected to port 3.
Here the corresponding parameter is 3/4. After the settings are completed, the user can start watching TV programs. The setup procedure for different receivers is similar, but the details may differ. The characteristics of the received signal are shown at the bottom of the settings screen. The level and quality are shown as a percentage. After the input has been completed, you need to save the settings made. To do this, just press the “Menu” key. If more complex switch wiring diagrams are used, then the denominator of the fraction will indicate the total number of available connectors. If over time the owner buys a new receiver or updates its firmware, then the setup will need to be done again.

How to choose a dysik
Before purchasing DiSEqC, you need to decide what you plan to use it for. Depending on how many converters must be connected, choose the type of device and wiring diagram. When buying, you need to choose a reliable manufacturer. For example, for this you can focus on the most famous brands. The earliest models could only connect to two converters. Now this number of connectors is considered insufficient. The most commonly used DiSEqC 1.0, which is designed to work with four devices. There are options with six or eight outputs. Since the differences in price are insignificant, it is better to purchase the latter. It should be borne in mind that the switch can be located on the street. In this case, it must be well protected from moisture in case of bad weather.When working with several satellites, you must pay for paid channels. Without this, there will only be access to free.

Possible connection problems
DiSEqC application allows simultaneous access to several satellites. However, sometimes after connecting through this switch, the signal completely or partially disappears. This may be due to the following problems:
- The most likely cause may be poor reception. Therefore it is important to check the accuracy of the antenna alignment. Make sure that it is correctly positioned and that there are no obstacles in the signal path.
- In some cases, the reason may be that the cable is not inserted neatly. To check this you will need to check every connection.
- Sometimes problems with reception can occur due to the fact that the user forgot to pay for paid channels. In this case, you need to check the balance and enter the required amount for payment.
- If the antenna has been in use for a long time, and the DiSEqC is installed outside, then we cannot exclude the possibility that it could have suffered from bad weather.

Questions and answers
Question: “If a user has purchased a satellite dish and wants to receive signals from two satellites, can he not buy a second one for this?”Answer: “With the help of multifeed, you can tune the antenna to two or more satellites. The number of converters used must match the number of broadcast satellites. Each of them is connected to a DiSEqC device, and through it to a satellite receiver. Then the reception of the channels must be set up. ” Question: “What to do if several satellites are connected, but the signal received from them is of insufficient quality?” Answer: “In this case, you need to do one of two things: make a more precise tuning for each of them, or increase the size of the antenna. In some cases, it is necessary to remove an obstacle in the signal path. For example, if it is obscured by a tree, then the satellite dish should be located in a different place. ”
