Pinout of HDMI cable and connector, pinout diagram. VGA-RCA adapter cable: description and purpose Tulip to component adapter

Those who own a significant amount of audio and video equipment are faced with a choice: make it yourself or purchase an adapter from the store that will convert signals of different types. Needless to say, factory devices cost a lot, but you can often do without them. And within the article we will talk about how to make a VGA to RCA adapter. Frequently asked questions will also be answered.

What is a VGA RCA adapter

The circuit of this device may seem complicated, but only until you understand it. What is this device? This is an adapter from tulips (RCA connectors) of analog video output to VGA D-Sub for 15 pins. The device reviewed here can be used to connect a DVD player or satellite tuner to a multimedia projector. Of course, provided that it is not possible to work directly using the same type of cable, which is usually common in cheap or outdated devices.

What is the idea?

How to implement such an idea? You need a computer cable (twisted pair type CAT5/CAT5e) designed to transmit video signals. We will use it because the transmission is carried out over a distance of fifty meters without loss of quality.

First, we need to acquire three RCA connectors and one D-Sub15 pin (this is a plug), as well as a twisted pair cable. The last part is better to use shielded STP than UTP. But this one is more difficult to get, which affects the price. Therefore, the issue of possibilities and desires is considered here. There is no particular difference between the elements, but there is one nuance: it is better to use UTP if the cable length is less than 10 meters. If the distance is greater, then it would still be better to find STP.

For the VGA RCA adapter cable we need six pins out of the fifteen presented. How to properly wire connectors and contacts? Check out this picture and you will understand how and what to do.

So let's see what happened. If everything was soldered correctly, then you now have an adapter that can supply a video signal to VGA D-Sub on the 15 pins of the projector. You can see approximately what the final product should look like in the photographs presented in the article.

Examination

It would be useful to heat-shrink the wires of pairs, at the ends of which RCA plugs are soldered, to obtain greater rigidity. In general, now you can connect the result of your work and enjoy it (if everything was soldered together as needed). Paired wires, at the ends of which RCA plugs are attached, can be crimped with heat shrink to obtain greater rigidity.

In this case, we used a satellite tuner with a 3 RCA component video output as a signal source and a Sanyo multimedia projector, which did not have a separate video input of the same type. If at the moment it is not possible to verify the functionality of the resulting adapter, then you can only carefully inspect the entire structure and make sure that there were no omissions, and everything is soldered as indicated in the article.

What you need to understand

You should be aware that the adapter in question can ensure the operation and full functioning of a device that has a VGA video input only if it can automatically detect the type of incoming video signal. An indicator of this will be the ability to select the mode in which data will be transmitted to RGB/YPbPr. Usage will be positively impacted by sending these types of signals. Why is that?

The fact is that RGB and HV.sync (for example, data coming from the output of a personal computer’s video card) are converted to RGB, which has sync pulses in the green channel (Y). It, in turn, turns into the color-difference YPbPr. And as a result, we can conclude that these signals are not the same thing, although they can convey the same information. Therefore, carefully study what a VGA RCA adapter looks like.

FAQ

Based on the data presented in the article, it can be assumed that readers have some questions. However, this is not the first time such a topic has been raised, so such information can be found without difficulty. We found out how to make a VGA RCA adapter with your own hands. Now let's look at its possible improvements.

What adapters can be made using twisted pair?

VGA extenders are special cables that have D-Sub 15 pin connectors on both ends, while their input and output use the same technology.
RCA (3xRCA) is used to transmit component video signals. There are three connectors at each end. Used when working with a DVD player and TV.
RCA (D-Sub15pin) was discussed a little higher. Here are the components Y, Pr, Pb in VGA.
To transmit analog audio, two pairs of stereo signals can be used simultaneously (4 RCA connectors at each end).

Why is a free Brown-Brown/Wht pair needed?

It can be used to transmit mono audio from a DVD player when there is an audio input on a multimedia projector (assuming it has speakers). Otherwise, it would be better to cut this pair and insulate it. Therefore, you should carefully consider the aspects and how the VGA RCA adapter will be used.

How can I make a Scart VGA adapter?

If the video source has a full Scart video output, then such a device can be made without problems. To do this, pinout the contacts is carried out as follows (outputs first):

7 - blue;
11 - green;
15 - red.

Now the ground:

5 - blue;
9 - green;
13 - red.

Otherwise, everything is done as previously described in the article.

Conclusion

Any final words? Carefully study the presented drawings and mentally imagine in detail what and how you will do. During work, exercise extreme caution and attentiveness - after all, if you miss the grounding, the consequences will be quite sad and very negative. The result is not VGA RCA for equipment, but the need to buy a new device for video playback. But if everything works out, then connecting a computer, projector, TV and many other devices will not be a problem now. The main thing is to make sure that all the pins are connected to the correct outputs, and no incidents will happen.

But at the same time, we can raise the question of the profitability of assembling this adapter. The fact is that you can buy it for 100-150 rubles, which is not a high price. Time spent creating an adapter on your own will end up costing more in the long run. The only acceptable option is if everything is already there, and you just need to make this device. From a purely amateur point of view, such experience can be valuable if one has an eye on work closely related to the restoration and creation of similar devices in the future.

You will need

Internet, very old video card with support for tv-out over d-sub, d-sub m connector, rca connector, 75 Ohm coaxial cable, soldering accessories

Instructions

On the Internet you will find a ready-made vga tulip connector, but unfortunately, even if you buy it, it will not work. To transmit a composite signal from a computer, it is necessary to support this type of signal standard. Until 2000, video cards with support for TV-out over d-sub were produced. That is, indeed, you could use a vga tulip TV adapter for such a video card. However, after 2000, the signal transmission standard was changed, and video cards no longer transmitted a composite signal. Thus, if you make a vga tulip adapter or buy a ready-made one and try to use it on a modern video card, the adapter will not work under any circumstances.

If you still need to output the signal from the vga output of a modern video card through the composite input to the TV (yellow video tulip), then the only way to do this is to purchase a special converter device. It transcodes the signal between different standards. The cost of this converter varies from 10 to 20 US dollars. This is a rather complex device, so only a professional can assemble it independently.

If you are the happy owner of an ancient video card (manufactured before 2000) that supports TV-out over d-sub, for example from Matrox, you can try making a vga tulip adapter yourself. To do this, you need a wiring diagram for the rca and d-sub connectors or “pinout”.

Prepare vga connectors and tulip for soldering. Open the protective case, apply flux to the required contact pads in accordance with the pinout. Take a piece of cable of the required length, strip the ends, and tin them.

Be sure to place the connector housings onto the cable before soldering it to the connectors. Solder the inner core of the cable to the center pad of the tulip connector and to pin number 3 of the vga connector. Solder the cable shield conductor (braid) to the other pin of the tulip connector and to pin number 8 of the vga connector on the other side of the cable.

Assemble the connectors at both ends of the cable. The adapter is ready. You can try connecting your TV to your computer.

Video on the topic

note

Pay special attention to setting the signal format, resolution and dehertz. Start with the lowest values. The TV may not recognize the video signal with most combinations of these settings, so try different options.

Helpful advice

The easiest way to connect a TV to a computer is a video card with a separate TV-out, tulip or s-video.

You can also use a converter.

Perhaps another way to connect your computer to your TV will suit you, for example:
- connection with a vga vga cable, if the TV has a vga input. Some modern TV models are equipped with a special adapter for connecting vga;
- connection via vga s-video adapter. This connection is possible on some models of ATI Radeon video cards, for example, the 3000 series, and special settings for the video card driver. The TV must also have an s-video input;
- connection via vga YPbPr adapter. The same as in the previous paragraph, but the TV must have a YPbPr component input (three non-yellow tulips);
- connection via vga SCART adapter. The same as in the previous paragraph, but the TV must have a SCART input (comb).

The VGA-RCA adapter cable is used to connect audio and video devices. For example, you can use it to connect a DVD player or a satellite tuner that has an analog component video output to a multimedia projector with a component video input. Quite often, users of household equipment are faced with a choice: buy a VGA-RCA adapter (or extension cord) or make it yourself. This is due to the fact that the cost of long original cables from leading manufacturers is quite high. And the monetary and labor costs for making such a device yourself are very small. In this article we will look at what a VGA-RCA adapter is, as well as its pinout. With this information, you will be able to make the mentioned cable yourself.

Description and pinout

To make the subject of our conversation, it is recommended to use (as a conductor) a CAT5 twisted pair computer cable (it is better to use a shielded one), since it is capable of transmitting a video signal without loss of quality over a distance of up to 50 meters. The VGA-RCA adapter contains three RCA-tulip type connectors (male or female, depending on the purpose) and a D-Sub connector (15-pin).

Pinout of the D-Sub connector for this adapter:

the first is signal red;
the second is signal green;
the third is signal blue;
the sixth is the land of red;
the seventh is the land of green;
the eighth is the land of blue;
Pins 4, 5, 9, 10, 11, 12, 13, 14, 15 are not used.

Thus, the VGA-3 RCA adapter requires only six pins. If you are using a twisted pair cable, then use colored pairs of wires to wire each cable. For greater rigidity, it is recommended to crimp the ends on which the RCA connectors are soldered with heat-shrinkable casing. That, in fact, is the whole description. The resulting RCA-VGA adapter supplies a component video signal to the VGA input.

Application

Very often they try to use a VGA-RCA adapter to supply a component video signal to a computer monitor. However, this cannot be done; the adapter will not work. This is due to the fact that the computer monitor does not receive the color difference component signals produced by the DVD player, but rather the RGB component. To ensure the functionality of such a connection, the use of a special transcoder is required.

Conclusion

The described method of making an adapter can be used for other similar products: 3 x RCA - 3 x RCA, VGA to VGA extension cables, etc. For example, you can make an adapter for an S-Video or Scart cable, the most important thing is to use the correct pinout these connectors. The use of twisted pair makes such adapters and extension cords very cheap to produce. If you need a short adapter, you can use an unshielded cable, this will further reduce your costs. And if you need an extension cord of 10 meters or more, then it is better to take a twisted pair cable with a copper screen. This will ensure high quality of the transmitted component video signal. It’s better not to skimp on this element, because no one will like watching a movie while “snow” or stripes appear on the screen, distorting the picture. It’s better to do it well once than to redo it and eliminate shortcomings.

Master's answer:

Today, many are interested in the issue of creating a vga tulip adapter on their own. The idea of connecting a TV to a computer appealed to many owners of such equipment. Moreover, it was precisely this interest that gave rise to a large number of speculations.

To connect a TV to a computer, you will need the Internet, an old model of video card with support for tv-out over d-sub, a 75 Ohm coaxial cable, an RCA connector, a d-sub m connector and a set of soldering accessories.

Of course, you can find a ready-made vga tulip connector on the Internet, but it will not work at all. In order for a composite signal to be sent from the computer to the TV, the video card must support the specified type of signal standard. Those video cards that manufacturers produced before 2000 were characterized by support for tv-out over d-sub. If you had such a video card, you could connect your TV using a vga tulip adapter. However, after 2000, there were changes in signal transmission standards, and the video card stopped transmitting a composite signal. In other words, if you make a vga tulip adapter yourself or buy a ready-made one, it will absolutely not work when used on a modern video card.

If you want to output a signal from the vga output of a modern video card model via the composite input to a TV (usually indicated in yellow), you need to take care of purchasing a special converter device. Thanks to this device, the signal is recoded between different standards. This converter costs between 10-20 US dollars. This device has a complex configuration, so self-assembly is only possible for a professional.

If you have an old model of video card (manufactured before 2000) that is capable of supporting tv-out over d-sub (this was produced by Matrox), you can try to make an adapter yourself. In this case, you will have to use the connection diagram of the d-sub and rca connectors or “pinout”.

The tulip and vga connectors must be prepared for soldering. To do this, remove the protective housing, apply flux to the required contact pads, and follow the pinout instructions. After this, a piece of cable of the required length needs to be stripped of the ends and tinned.

Before soldering the cable to the connectors, you must place the connector housings on it. It is necessary to solder the inner core of the cable to the central contact pad of the tulip connector, and the other end to pin No. 3 of the vga connector. Then the braid, or shielding conductor of the cable, is soldered to the other pin of the tulip connector, and on the other side - to pin No. 8 of the vga connector.

Then the connectors are assembled at both ends of the cable, after which your adapter is fully usable. Now through testing the connection of the TV to the home computer.

note

Particular attention should be paid to setting the resolution, signal format and dehertz. They always start with their lowest values. Since the TV may not detect the video signal in most combinations of settings, you should try different options.

Useful tips

Conclusion

Hi all. For a very long time, I had an old seventeen-inch monitor lying on the roof, which was covered in dust. It lay there for a long time, exactly until I accidentally came across an article about a signal converter from RCA (popularly “tulip”) to VGA. There, the author of the article connected the monitor to a satellite tuner, and used computer speakers instead of speakers.

I also decided to do the same trick with my old monitor, so to speak, to give it a second life as a TV in the kitchen. After ordering, namely 18 days later, I received the package by mail.

The device itself was packaged very well, namely wrapped in a bunch of layers of bubble wrap.

Having reached the contents, we have the following configuration:

Converter
power unit
VGA to VGA cable
RCA to RCA cable
S-video to S-video cable
Instructions in English.

Converter equipment

As you can see, the package is not small; all the necessary cords are already included.

I was very surprised by the coating of the converter housing itself. It is covered with soft touch, which feels a little like a rubber coating. It is thanks to him that the case is much less susceptible to any mechanical damage, and is so pleasant to the touch.

After the purchase, I received an unpleasant surprise from my old monitor. After lying on the roof, it refused to turn on, so for demonstration I connected the converter to another, now Led, monitor.

Everything connects very easily. Cable from the monitor, plug into the connector VGAOUT, plug the cable from the tuner or DVD into the connector VideoIN. The power supply is in the socket, and its output is in the connector 5 vPower. After this everything starts working.

Example of work

On my monitor, a perfect picture immediately appeared, even taking into account that the signal comes through an analog RCA cable. The converter has a menu that allows you to adjust some parameters, such as brightness, image offset, but I didn’t touch anything there. We only used the mode button, which is responsible for switching the screen extension, selecting the desired extension specifically for my monitor.

If you decide to make yourself the same TV from a monitor, I recommend this particular adapter, since its quality of work is at the highest level.

I bought Here. The seller is very good, sent the goods on the second day.

Thanks everyone for watching.

PS. The old monitor was repaired; there was a crack on the TDKS.
