VGA-RCA adapter cable: feature description. Self-closing adapter vga tulip. VGA-RCA adapter cable: description of the Vga 3rca adapter pinout

- Transitioner, which allows you to connect the computer's video with the greatest color TV. Below, we will look at some options for a similar adapter, describe the pluses and minuses of the skin construction, and we will guide you for the sake of making a VGA SCART adapter with your own hands.

First of all, one important clarification: all the instructions are given in the same ker_vnitstv_ presentation “like є”, and leather vicorist їх on your own fear and rizik.

Application of VGA-SCART accessories

In order to understand the function of pointing below the circuits of adapters to VGA SCART, let's look at different types signals, as it is necessary to send from the computer to the TV.

RGB signal

The main signal, which is transmitted over the cable from the computer to the TV, is an RGB signal divided into three warehouses (R-black, G-green, B-blue). to this particular type standard and SCART sockets are more summative (appearance: amplitude 0.7V, opir 75 ohm). To this, you can directly connect all kinds of contacts, without going into the selection of special schemes or outbuildings (we will look at this option later).

Zagalniy provіd

In VGA and SCART roses, a sprig of visnovkіv can be connected from a hard wire (mass), as often they are connected one by one to the middle cable. Їхнє спільне с'єднання allows you to make a new change of lines (especially if there are three RGB lines). The same should be done with the screened cable.

Note: as a matter of fact, the wild drіt is only one, so it’s normal that all contacts, that may be known, are connected at once.

720p/60Hz, 1080p/60Hz...

Audio and video converter

Audio signal

In order to send sound to the TV, you need to take a cable with a standard 3.5 mm PC plug and connect it directly to the SCART socket. You can play both mono and stereo sound, without going into the special outbuildings that schemes. Just be careful not to confuse the audio output with the audio input, the shards at the SCART stink of the order.

Switching signals

As it was thought earlier, SCART input can accept different types of signals. In order for the TV to understand what type of signal is applied to the input, it needs a special contact RGB Blanking (visnovok 16). Yakscho on Danish contact apply a voltage of 0 ... 0.4 V, then the TV will display "Composite signal", i.e. 1 ... 3V, then the signal will be "RGB". The choice of this type of signal is also important for the functioning of the VGA-SCART adapter, and as we have done, it is clear different ways take yoga.

The second visnovok, which can zatsіkavit us - tse Swtch (visnovok 8). Tsey vysnovok appointments for switching to the TV / AV mode. Also, on some televisions, these visnovoks allow you to install the “spivdnance” of the image side:

• TV mode mode – type 0 to 2 V.
• AV mode from 16: 9 - from 5 to 8V.
• AV mode with 4:3 ratio - from 9.5 to 12V.

If you don’t send a signal to this visnovok, the TV will be left behind in the locking station (TV mode), and even to switch to AV mode, we will need to speed up the remote control.

Synchronization signals

Here it is better to start with the power supply of the VGA-SCART adapter. Synchronization of signals in the video card of the computer is strongly affected by the synchronization system, as it is great TV, so it is necessary to go into some cunning, so that you can make them sum up. Vіdminnіst vіzh itself bіshostі schemes VGA-SCART adapters are based on ways to solve the problem.

The computer has a standard VGA which transmits two different signals for synchronization, one vertical (60 Hz) and one horizontal (31 kHz). Obidva signals work normally up to TTL logic and, therefore, may have a peak value, which is more expensive 5V. If you get there, the signals can be either positive or negative, depending on the mode of work and video.

At the same time, the TV needs only one warehouse signal of synchronization with peak values ​​close to 1 ... 3V. Also, the frequency of the horizontal rise is significantly lower, close to 15 kHz (vertical, but in practice it is 50 ... 60 Hz). Nareshti, the signal is guilty of a negative character.

The main problem, which seems to be mystifying, is horizontal synchronization. Choose the scheme of which transformation to complete the task more smoothly. In this case, as a rule, make changes to the very signal signal (video card), vikoristovuyuchi special software security Or you can use VGA modifications (for example, the famous ArcadeVGA), so that you can take 15 kHz directly on the VGA output. Take a look at the food.

Removing the 15kHz sync signal by software

As has already been guessed in the front division, the decisions of the head office with the need for a VGA SCART adapter to remove the horizontal sync signal at 15 kHz. As a rule, the solution is available for changing the account, mainly in the field of software security, customizing the video card personal computer. On the other side, the synchronization signals may be negative, that is. with a constant equal to + 5V, which is straight to zero under the hour of the impulse itself.

Program Soft-15kHz

All software security for Winows XP/Vista, created by a German programmer, allows more in a simple way Select a 15 kHz sync signal of the negative type. Won sum with more video cards and even simpler with most video cards.

The only її nedolіk є those who need an hour to launch operating system the signal from the video card is too low at 31khz, so you can’t get anything until the end Windows takeover. It's easy to download with Soft15khz program: once you're interested, just unpack the rar-archives with the program and run it (installation is not required), then click on "Install 15kHz" and reboot the computer.

(1.4 MiB, vanquished: 2464)

Tse harder software for editing all the parameters of the video card, including the removal of a 15 kHz sync signal. The program is not cost-free, although it can be successful in a smart-cost-free version (the only shortfall in this case is the screensaver's presence, which takes about six seconds at startup). You can download the PowerStrip program from the official site.

Removal of 15 kHz clock signal by hardware

Now let's go back to the development of various VGA SCART adapter schemes, starting from the simplest to the most complicated. Pochnemo, maybe, with the pinning of the VGA and SCART pins:

Basic scheme with composite synchronization (only for ATI RADEON video cards)

• Plusy: Easy to implement, does not require any special components
• Cons: You need 5 and 12V power supply, it works only with ATI Radeon video cards.

Basically there are three RGB lines (VGA pins 1, 2, 3) that are connected to the secondary SCART pins (pins 15, 11, 7). It is also necessary to close the throat of the skin canal (extremely enough one deep throat, but for the yakish screening it is better to use vicorist). For this VGA card (6,7,8) you need 13, 9, 5 SCART.

Qi links are the same in all transition schemes. Dotted brown wire, which is the rear pin 10 VGA and SCART 17 hot wire for the sync signal. Black drіt, scho zv'yazuє screened shell cable both roses. I, on the right side, brown wire, which goes to 13 pin VGA to 20 SCART transmits a warehouse synchronizing signal.

UVAGA: In order for the scheme of the VGA SCART adapter to work, it’s important that the video card supports the mode of the synchronizing signal on the input 13, which sounds like a daily sound in most video cards and only a few video cards, which can lie down to RAM, ATI Danish mode roboti.

Removing the synchronization signal for additional diodes and resistors

• Plusy: Working with any video cards, the activation of the function is boosted by a call signal.
• Cons: Need a living room 12B.

Let's take a look at the transition diagram. In this way, the lines R, G, B are connected in the same way as in the front scheme. The scheme allows you to use a custom video card (which does not generate a composite video signal). Synchronization signals from contacts 13 and 14 VGA are sent to the lancet diode and resistor 330 Ohm, and then transmitted to the original 20-pin Scart.

Switching bipolar transistor for mixing two synchronizing signals safely garna yakist image.

Deputy Vice Chancellor hello dzherel live, voltage 5V taken from live 9 VGA. True, not all video cards of the building can provide this voltage, especially cards of the older generation. Have a blast with everything other models sums with VESA 2.0 are due. In this scheme, the switch 8 is supplied not with 12V (for switching on the AV mode), but with 5V. For the help of the TV set, the mode of switching between the sides will be activated at 5V, the 16:9 switch will be activated instead of 4:3.

Chip adapter 74HC86

• Pros: Vіdmіnna yakіst ta sumіsnіst (working with be-yakim videocards)
• Cons: Without a doubt one of the most folding schemes.

The scheme of the VGA SCART adapter was inspired by the integrated microcircuit 74HC86 (which includes the logical elements “Turn off the ABO”). It is also necessary to have the presence of the old dzherel of life 5V. Signals are sent for additional elements that turn on the ABO, at the output of which a composite signal is output vіdminnoї yakosti. The adapter works with any kind of TV, be safe negative signal at a frequency of 15 kHz.

Tі, hto є volodar є znachny іlkostі іlkostі аvіdio-videoаpаratury, stanovіv vybora: zhobite yоm аbo go to the store і аn adapter, yak konvertovatimé signal different types. As it turns out, although the factory outbuildings are cheap, you can often get along without them. І within the framework of the article, it will be explained how to get a VGA RCA adapter. There will also be vouchers for power supply, which is often set.

What is a VGA RCA adapter

The scheme of this accessory can be folded, but only until the moment you figure it out. Chim є tsey pristriy? Tse adapter from tulips (RCA roses) for analog video output to VGA D-Sub for 15 pins. This attachment can be used to convert a DVD-programmer or a satellite tuner to a multimedia projector. Obviously, for your mind, there is no possibility of working without intermediary for the help of the same type of cable, so it sounds wider in cheap and old accessories.

Who has an idea?

How to implement such an idea? You need a computer cable (type - a twisted pair of classification CAT5/CAT5e) for the purpose of transmitting a video signal. Vikoristovuvatime the same yogo through those that the transmission zdіysnyuєtsya at a distance of fifty meters without wasting power.

For the cob, we need to get three RCA sockets and one D-Sub15 pin (the same plug), as well as a twisted pair cable. The rest of the detail is better to take the screened STP, lower UTP. Ale, such a folding distance, which is indicated on the price. That is why here one can see the nourishment of possibilities, that bazhan. There are no special differences between the elements, but there is one nuance: UTP is better to beat, as the length of the cable is less than 10 meters. If you know more, then you will still know STP better.

Pinning

How to make a pinout for a D-Sub socket on 15 pin? Numbers go zliva to the right:

1 - R-Y (Pr).
2-Y.
3 - B-Y (Pb).
4 - Ground - Brown.
5 - Ground - Wht\Brown.
6 - Ground R-Y (Pr) - Wht\Red.
7 - Ground Y - Wht\Green.
8 - Ground B-Y (Pb) - Wht\Blue.
9 - Not needed.
10 - Ground.
11 - Not needed.
12 - DDC DAT.
13 - Horizontal Synchronization.
14 - Vertical Synchronization.
15 - DDC Clock.

For a VGA RCA adapter cable, we need six pins for fifteen. How to correctly set up the soldering of roses and contacts? Familiarize yourself with this little one and you will understand how and what to work.

So let's wonder what happened. If everything is correctly soldered, then you immediately have an adapter that can feed video to VGA D-Sub to 15 pins of the projector. How can you look like a final product, you can marvel at the photos presented in the article.

Revising

Provid pairs, at the end of which RCA plugs are soldered, will be crimped with heat shrink in order to get more hardness. Zagal at once, you can connect the result of practice and savor it (as everything was soldered, as required). Guys darts, at the end of which there are RCA plugs, can be crimped with heat shrink to get more hardness.

This type of speaker had a satellite tuner with a component video output for 3 RCA in the capacity of a signal jack and a Sanyo multimedia projector, which was not transferred to the same video input. Since at this moment there is no possibility of reconciliation in the practicality of the adapter, which is wiyshov, then we can only respectfully look at the entire structure and reconsider, so that there were no omissions, and everything is soldered as it is designated in the article.

What do you need to understand

It should be noted that the sighting of the adapter can secure the robot and fully functioning add-on, which has a VGA video output, only in that case, it can automatically direct the type of video signal. An indication of this will be the possibility of choosing the mode in which data is transmitted on RGB / YPbPr. On the selection, the strength of the assigned types of signals is positively indicated. Why so?

On the right, in that RGB and HV sync (like, for example, this, which goes from the output of the video card of a personal computer) is converted to RGB, which can sync in the green channel (Y). Vin, in his own line, transforms into a color-variant YPbPr. As a result, it is possible to create visnovoks, that these signals are not one and the same, although they can transmit the same information. It is respectful to remember that, as it looks like a VGA RCA adapter.

Power extension

Based on the data presented by the article, you can assume that the readers may have some food. However, such a topic is not up to date, so such information can be easily known. Mi z'yasuvali, how to get a VGA RCA adapter with a hand. Now we can look at the yoga thoroughly.

What kind of adapters can you work for an additional twisted bet?

• Support VGA - special cables, which can be used with D-Sub 15 pin roses on both ends, with the same input and output, they use the same technology.
• RCA (3xRCA) is used to transmit component video signals. There are three roses on the skin tip. Zastosovuєtsya when working with a DVD-player and TV.
• RCA (D-Sub15pin) was seen troch wide. Here are Y, Pr, Pb components in VGA.
• In order to transmit analog sound, two pairs of stereo signals can be played at the same time (4 RCA roses on the skin end).

What is the Brown-Brown/Wht pair for?

Її you can twist, so that you can transmit a mono audio signal in DVD player, if there is an audio input of the multimedia projector (be aware of which speakers are available). In the protileous type, it is better to cut and insulate a couple more often. Therefore, it is good to think over the aspects and those, like a VGA RCA adapter, can be used.

How to get a Scart VGA adapter?

If there is a new Scart video signal available for the video signal, such an attachment can be installed without problems. For whom to carry out the pinning of contacts in the coming order (on the back of the head):

• 7 - blue;
• 11 - greens;
• 15 - red.

Now land:

• 5 - blue;
• 9 - greens;
• 13 - red.

Otherwise, everything will work as it was described in the article.

Visnovok

What can you say nasamkinets? It is important to consider the presentation of the little one and to show on the details of the thought that you are working. Under the hour of work, take care of the border guard and respect - even if you miss the ground, then the consequences will be summed up and even negative. The result does not have VGA RCA for technology, but the need to bring a new attachment for video production. All the same, everything is connected - the installation of a computer, a projector, a TV set and a bagatioh іnshih fittings will not be a problem at once. Golovnya, it’s necessary to change your mind that all the whiskers come before the necessary departures, and there will be no everyday incidents.

But at the same time, it is possible to destroy the nutrition and profitability of the storage of this adapter. On the right, in that yoga can be bought for 100-150 rubles, but not at a high price. An hour, stained glassing of a self-tapping crossover, I dare to pay more dearly. The only acceptable option is that it’s all the same, and it’s only necessary to build these attachments. From a purely amateur point of view, similar insights can be valuable, as if aiming at work, closely related to inspirations and creations similar outbuildings in the future.

The name HDMI (High Definition Multimedia Interface) literally translates as High Definition Multimedia Interface. A standard HDMI cable has 19 wires. Knowing the cable pinout scheme, you can connect to a new HDMI socket, or you can help by shaving the wire, and replace the sockets. The numbering of the last contacts of the socket is carried out on the right side, and in the upper row there are contacts with unpaired numbers, and in the lower row - with guys.

HDMI is used as an interface for transmitting uncompressed digital video and audio signals high capacity. HDMI interface supports maximum transmission of video and audio signals in such formats as DTS, LPCM, DVD-Audio, Dolby Digital, Super Audio CD, etc. HDMI can provide maximum data transfer speeds of up to 10.2 Gb/s (340 MHz). Wicker interface TMDS protocol.

HDMI sockets (min, micro) and their pinout

• Type "A" - 19 contacts, specification 1.0
• Type "B" - 29 contacts, specification 1.0
• Type "C" - 19 contacts (mini), specification 1.3
• Type "D" - 19 contacts (micro), specification 1.4
• Type "E" - 19 contacts, specification 1.4

Pinout HDMI Type A (19pin)

Pinout HDMI Type B (29pin)

Pinout HDMI Type C mini (19pin)

Pinout HDMI Type D micro (19pin)

Pinout HDMI cable by color

HDMI cable split into 5 groups of 3 lived. And 4 more lived to walk around. Roz'єm will ensure the switching of several groups of screened symmetrical lances for the transmission of digital video signals (screen made of aluminum foil), as well as darts of service data and life.

There is no single color marking lived, and at the skin cable cutter, you can have your own marking. The test instance of the HDMI cable had the same cable.

Pinning the hdmi cable to sound

The sound of modern TVs or set-top boxes sometimes only comes out via HDMI (without loud audio outputs or like headphones, so there is no old audio output). Tom has to think like "vytyagti" beep from eychdimiai nests. For this, you can buy a special audio adapter on Ali (600 rubles) in a small box that draws sound from the HDMI signal and outputs it in analog, looking at two RCA tulip roses, or in digital to optical SPDIF.

HDMI-DVI pinout

Pinout HDMI socket to RCA tulip

Sound with an HDMI-RCA adapter if necessary, or transfer data in video and audio formats. Every lucky cable has a special chip that plays the role of a changer digital signal HDMI for composite video or audio. Let's let the signal go through the rose "tulip" on the TV screen.

To convert a purely digital HDMI signal to an analog one (S-Video, component or composite), you need not just an adapter, but a whole set of attachments that add up to accepting a digital signal, a DAC sprat, a molding machine TV signal, Well, I’ll buy more parts for dribnitsa. It's too foldable to be called simply a transitional person.

The design of the vikonan adapter is like a miniature hardware module with a wire. On one end there is an HDMI connector, and on the other end there are three different-colored tulip roses.

HDMI-VGA adapter pinout

The HDMI-VGA adapter is made up not only from the same dart and sockets. The HDMI-VGA cable is a whole circuit on a microcircuit, soldering it is very difficult - just buy a ready-made adapter (as you can see the sound from such a cable). The price of yoga on Ali is about 700 rubles.

HDMI to HDMI adapter

Do-it-yourself HDMI cable preparation

preparation HDMI cable in the minds of the home is not a problem - just take a piece of dart of the necessary dozhina and the necessary roses. Strip a couple of centimeters from the braiding, remove the insulation from the wires and carefully tint them.

Depending on the fact that roses need to be twisted on the ends of the cable, we choose the pinout scheme and solder it. For example, if you need hdmi plugs on both sides of your mother, the scheme will be like this:

Here is an option for standard size, so i min or micro hdmi.
