Differences between the models OPENBOX ® X-730PVR, X-750PVR, X-770CIPVR

At the moment the 700-series model, the following receivers:

Model	Card reader	CI-Interface	Time-Shift	Record on USB-Memory	Color receiver
Openbox X-730PVR	1 piece	no	No	Yes	silver
Openbox X-750PVR	1 piece	no	built-in 1GB memory	Yes	silver
Openbox X-770CIPVR	1 piece	2 pcs	built-in 1GB memory	Yes	black or silver
Openbox X-790CIPVR	1 piece	2 pcs	built-in 1GB memory	Yes	black

When you select the receiver, be aware that an important difference model Openbox X-730PVR is No built-in 1GB memory and hence the regime Time-Shift.

Initially, the model Openbox X-730PVR Time-Shift mode planned to realize when you connect an external USB-drive (Flash, HDD, etc.). Given that the market has a significant number of USB-drives, becomes unstable when the active exchange of data sheet, from the Time-Shift mode in the model Openbox X-730PVR had to give up (all the recording features are left).

 

Which processor built receivers?

All the receivers of the new series are based on modern processors CX2430x company Conexant. The distinctive feature of this series is the high integration and a new 32-bit ARM core with a high operating frequency of 150MHz. Through the integration of QPSK modulator, USB-controller and other modules in a single package, managed to significantly reduce the cost of the finished product.

At the same time, qualitative indicators of audio / video decoders are at a very high level, which allows little or no loss to reproduce the signal.

It must be remembered that the use of the new processor is not yet a success, a very important role played by the software, as well as the circuitry of the receiver. Software, in most cases, is responsible for the functionality of the product, and circuitry - for its quality indicators.
For example, processors Conexant family CX2430x provide excellent output video, but banal savings on components of analog circuits in the design of the receiver, can give a disgusting picture quality when connected to a TV.

In the development of receiver circuitry 700-series involving the best engineers of the industry, and the result of their work can be seen in a crystal clear and crisp images, even on large screens with a diagonal.

 

How to connect your receiver to your TV (LCD / Plasma panels) on the component?

For the highest quality images, it is desirable to use the connection with separate colors (RGB) or component video signal (PbPrY). In the former case, the standard can be considered cable SCART <-> SCART, but the component connection will need a special cable.

Given the relatively small size in the receiver corps of 700-series, on the back panel is not enough space for three full-RCA-connector component video outputs (PbPrY). But the component video output in devices vseravno present, it is implemented on the SCART TV connector.
For component video signals (PbPrY) uses the same DAC, which is issued through the RGB-output (only necessary to activate the appropriate video mode in the menu).

To connect the need to purchase or make yourself cable SCART <-> 3 x RCA.

Receivers are built on the processors of the company Conexant, which, unlike those present in the market of products, have a slightly different architecture of the video decoder. Therefore, the corresponding signals on SCART TV connector in the component mode, the receiver 700-series is somewhat different than bolshinsva other devices.

Fork, inserted in the receiver	Openbox 300/800/7200	Openbox 700-Series	RCA-connectors are included in the TV
	7 - B - Pb 11 - G - Y 15 - R - Pr	7 - B - Pb 11 - G - Pr 15 - R - Y

As is clear from the table, using the component connection receivers 700-series, ponadobtsya only swap connectors Y and Pr. 

 

During the software update is lost electricity and the receiver does not turn

In most cases, the owners of receivers 700 series can use a modern USB-port for software updates, and transfer the settings on your computer. This method provides excellent performance and does not require a computer next to the receiver.
Despite this, already "old" port RS232, can be a vital tool in situations where the receiver is out of order. And the reason of failure may be banal disappearance of electricity at the time the software update via USB-drive.

To work through the RS232 port will need to "Null-modem cable with connectors such as" Female RS-232 ".

Cable can be purchased at the nearest company that sells computers or make yourself at the figure below.

The cable consists of three wires, two of whom are mixed (5-5, 2-3, 3-2).

If you use a laptop computer or simply do not have a computer COM-port, you can buy USB <-> RS-232 adapter, such Viewcon VE42.

Now run the program Porter, ask the mode (Mode - Software) and select the file with the software for our receiver.

The next step, click the Download button and turn on the receiver, to run the horizontal column with information on the percentage completion of the operation.

After the operation, on the front of the receiver will light inscription End, then the receiver will reboot and be ready to receive remote commands.

 

What file system supports drives receiver?

Receivers are compatible with many devices such as USB Mass Storage, but the drives should have a file system type FAT16 or FAT32. NTFS file system and others are not supported receivers.

 

How to properly connect large-capacity drive?

Satellite Receiver is a domestic device, so to integrate it all the possibilities the PC is impossible. Therefore, before you connect a new hard drive, need help computer.

If you drive a small amount, it can be contributed by the Windows XP (Disk Management) to create a partition and format it in FAT32. To create a FAT32 partition larger than 32GB will need special software (Partition Magic ...). But to solve this problem can and other, easier way:

1. Connect the drive to a computer with Windows XP and create a partition but not format it.



2. The next step is to connect the drive to the receiver, go to Menu> Format (USB) and format the drive.



Now the receiver displays the amount of available disk and can be used to record programs.

3. If the first stage of the disk has not been assigned to the letter, it can be done now (In Windows XP for this is the Disk Management utility).



After that, the contents of the disc will be available through normal conductor.

 

In what format you're recording?

Record receivers produced in the format *. TS, but still only one audio track. When the maximum file size for FAT32 (4GB), for automatically breaking receiver recording into multiple files.

All entries can be viewed on a computer or converted into other formats. It also enables the playback of the receiver party video, pre-transformation in TS .*

Receiving signals from multiple satellites on one antenna

Multifeed

Multifeed - a device for receiving signals from multiple satellites on one antenna.

 

The surface of the satellite dish as a mirror reflects the signal from a satellite and focuses it in a certain place called focus.
As quite often happens that a few satellites inetersuyuschimi your programs are far from each other, it becomes possible to assemble the device, which can accommodate some converters next to the focus of the antenna, at the points of focus signals of these satellites

Figure 1 Principle of multifeed

 

Figure 1 shows that the signal from the satellite to a converter in accordance with the laws of reflection. When we set up the antenna on one satellite, you have a converter like the focus of the antenna, and dish, respectively, we look directly at the satellite. There is also a zone and the maximum signal level. But if we have a plate big enough, and the nearby satellites are quite acceptable for the signal power in our area, we can in accordance with a scheme to try to locate close to the main converter by others, and to receive signals from satellites of interest to us. In most cases, you should configure the central LNB on a satellite with the weakest signal. But in each case is to decide separately. For example, in central Europe is the weakest satellite to view the Russian-language television - Amos, but it is usually properties of the edge multifeed. because it is the least interesting of the others taken at multifeed three satellites - Sirius Hotbirda. Asters and is located on the extreme position.

 

To determine the possible signal reception enough to pick up a converter with cables connected to it, to enter into the receiver parameters of the most powerful transpordera, located on the satellite, and gently moving the converter in place to be a secondary focus is to try to catch the signal. It should be guided by such rules: The satellite signal is located to the left of the main will be taken in the area located to the right, if you look at multifeed is behind the plates, as shown in Figure 1, and vice versa. Also the signal from the satellite located above the orbit will be made below, and vice versa. It may be that the converter you will not even look at the center of the plates and rotated around the horizontal axis. After you place niluchshego reception can begin to assemble multifeed, ie attachment for additional converter. There may be various options, depending on in which Ku-band or C signals are transmitted at what distance are from each other converters, etc.

Those who wish to calculate the theoretical location of the converters can use the formula proposed by J. Forfun and published on the forum "Byvaly Maker. There you can clarify for myself and many other strange moments of the construction multifeed

Shift converters in multifeed both horizontally and vertically, can be accurately calculated on the assumption that the angle of incidence equals the angle of reflection:

A = F x sin | a |,

where F - focal length, | a | - module azimuth difference and elevation angles

WARNING !!!!!

To offset antennas in the formula for F must not expose the focal distance, and distance from the converter to the center offset more've seen it here

 
For those who have sufficient access to the antenna, enough empirically to find the best position of the converter at multifeed, moreover, that the specific characteristics of some Chinese dishes especially intended for reception in the C range is often quite different from the characteristics stated in the data sheet, and multifeed calculated by the formula may not provide sufficient reception quality.

Construction multifeed for receiving Russian TV in Western Europe

In Western Siberia, the construction multifeed are complex, as transpordery taken from different satellites are located in the upper Ku-band and in the lower C. The task is complicated not only by the fact that the converters have different sizes and hence have to create their own attachment to them, but so that the configuration of a satellite in C band harder than Ku, since the signal is in this range is more susceptible to a variety of industrial noise, and converters with the range it is important to correctly position the polarizer and the reflector, which is not always an easy task for China's cheap heads

Construction multifeed and recommendations for setup for the reception of television in Western Siberia on information from the website: www.sputnik-tv.com/

To view the channels from satellites Yamal, Ekspess-11, Express-6A, and the LMI must make multifeed. Once assembled, it looks like the photo. Multifeed installed in pryamofokusnuyu dish SVEC, China. The quality on all channels using Receiver Topfild-4000Fi 98-99%.

First, set up a central head on Yamal. It's no big deal, and maximize the signal on all transponders. Then catch the satellite Express 6A, there would have trouble, because the patched on weak transponder most interesting channels.

Ekspress11 caught very easily, because The satellite signal is very powerful, and customize virtually anything not necessary.
With head LMI have the most trouble, because must be very precise position to pick up, not knocking the settings of other heads.





Once you have compiled and configured multifeed need converters to connect to the receiver. For Option 2 to 4 converters used Switches DiSEqC, which switch converters, depending on which channel you choose when watching TV on the receiver. To learn more about the principle of a switch you filter can learn here
 

Connect 4 LNBs to the receiver.

 

With options to connect a larger number of converters can be found here

 

Next in the setup menu receiver to the number or names of satellites aligned with the order to connect the corresponding outputs of the converters to switch. Sometimes it happens that some converters do not work consistently with some types of switches. In this case you should try to connect the other converters, or purchase a higher quality switch, providing a good enough outcome. For example, the German switches "Spaun" practically free from these shortcomings, but their value is high enough.
