USB to USB Cables

USB or Universal Serial Bus standard was designed in the mid 1990 to replace old standards like serial or parallel ports.  In our days the USB connector can be found in keyboards, printers, digital cameras, flash drives, external hard drives and almost all peripheral digital equipment.

Until now three USB standards were released:
  • USB 1 released in 1996 with speeds of 1.5 Mbps for Low-Bandwidth and 12 Mbps for High-Bandwidth;
  • USB 2.0 release in 2000 is the most used usb port at the moment at supports a maximum speed of 480 Mbps;
  • USB 3.0 released in 2008 in the latest standard who can support speed up to 5Gbps.
There are 7 USB connector types: type A, type B, Mini-A, Mini-B, Micro-A,Micro-B and Micro-AB. Type A and B has 4 pins, Mini and Micro A and B has 5 pin usb pinout.

 Pinout description for main usb connectors:

usb to usb

Micro usb pinout has the same configuration as mini usb. Both will be discussed in particular in other articles on this website.

USB voltage can vary from 4.75V to 5.25V and the amperage is 100 mA for USB 2.0 and 150 mA for USB 3.0. If you want to charge a device or a home build circuit then you must know that for a UBS 2.0 you can draw a maximum of 500 mA or 900 mA for usb 3.0. By using a voltage convertor you can even charge your cell phone or other device who doesn’t require a high power supply source.

USB standard is compatible with almost all other standards. You can buy a rj45 to usb adapter with only a few dollars or you can make one. When building your one usb adapter you have to be very careful with the other standard pinouts like Ethernet pinout or rs232 pinout because you can connect the 5 volt output to the data- or + of  your motherboard usb pinout and do short circuit.

Frequent questions about usb pinout:
  • USB 3.0 have the same pinout of USB 2.0 ?
No, USB pinout for 3.0 standard is different,  it has 9 pins from which two are used as a super speed receivers another two as super speed transmitters and one for GND drain. We will cover the USB 3.0 pinout in other article.
  • What is the iPod pinout ?
Ipods are not equipped with a usb port, they have a 30 pin port and latest models came with an adapter compatible with usb, dvi, hdmi and other standards. Usually Apple devices are equipped with a firewire port or 30 pin port. You can buy an adapter or make it yourself but be careful at the firewire pinout.
  • What is the usb pinout color code?
For USB 2.0: 
Pin 1 – Red-VCC
Pin 2  - White – D-
Pin 3 – Green – D+
Pin 4 – GND – black.
  • USB port not working!
If your USB port is not working you first have to check to see if the device that you are trying to connect works properly and if it does then one of these three problems has occurred: usb card is not connected to the motherboard (to see if this is true you can check the voltage between pin 4 and 1); your usb device needs a software to run (in my computer – device manager check for uninstalled hard drives, usually signaled with a question mark) and the last one you usb port is broken (if you have a desktop pc then you can change the old usb card with a new one and if you have a laptop I recommend a specialist to do that job).

    Ethernet RJ45 pinout connector 10/100Base-T

    Ethernet 10base-T / 100base-TX pinout. Widely used in ethernet network devices. Same connector and pinout for both 10Base-T, 100Base-TX and 1000base-T.

    Nowdays ethernet is a most common networking standard for LAN (local area network) communication, officially standardized by IEEE standard 802.3. Nowdays ethernet runs at 10Mb (10base-T), 100Mb (100Base-T) or 1Gb (1000Base-T) per second. It was originally developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus (old coaxial cable) or star topology (standard UTP cable). Most ethernet networks use unshielded twisted pair (UTP) cable. Category 5 (CAT5) cable widely used, but other variations are available. EIA/TIA specifies RJ-45 connectors - properly called 8P8C - (ISO 8877) for UTP (unshielded twisted pair) cable. (RJ45 refers to a set of connectors beyond the 8P8C standard but the former has replaced the latter in common usage).

    Length of CAT5 cable runs should not exceed 100 meters.

    Please note that it is very important that a single pair be used for pins 1 and 2; 3 and 6, 4 and 5 (if used), 7 and 8 (if used) in any common straight-thru UTP Cat5 network cable. If not, performance will degrade. Also note that TX & RX should be swapped if two computers are connected without switch/hub  and for connecting some devices without MDI-X autosensing (see UTP crossover cable).

    S-Video is commonly used in many consumer TVs, DVD players, video tape recorders, game consoles and almost all TV-out connectors of graphics cards.


    Pin Name Description
    1 GND Ground (Y)
    2 GND Ground (C)
    3 Y Intensity (Luminance)
    4 C Color (Chrominance)


    Notes

    • The luminance (Y; greyscale) signal and modulated chrominance (C; colour) information are carried on separate synchronized signal/ground pairs. This increases bandwidth for the luminance information, subdues the color crosstalk problem and leaves more video information intact, thus having a improved image reproduction compared to composite video.


    Power Supply Connector Pinout ATX 24 Pin

    Changes to ATX standard were made to support 75 watt PCI Express requirements. Most power is now provided on 12 V rails and the power on 3.3 V and 5 V rails was significantly reduced. The standard specifies that two independent 12 V rails (12 V2 for the 4 pin connector and 12 V1 for everything else) with independent overcurrent protection are needed to meet the power requirements.
    New ATX v 2.2 uses new connector, but most motherboards nowdays allow to use an old ATX v 1.x power supply with ATX 20 pin connector - it connects to 24 pin motherboard receptacle.

    18 AWG is recommended for all wires except pin 11, which should be 22 AWG. For 300W configurations 16 AWG is recommended.

    Power Supply Pinout, AT Motherboard

    AT PSU's were used before ATX become to be standard.
    An AT power supply delivers +5 V, +12 V, -5 V and -12 V voltages using two six-pin connectors. A few newer boards used an aditional connector for +3.3 V. Note, that you must install these connectors to the motherboard in a way that the black wires are placed on the center, or your equipment will be damaged.

    Cable connector is Molex 90331.
    The original PC debuted in 1981 and used two cables to connect the PSU (power supply) to the motherboard. The two cables plug side by side into the motherboard connectors. Sometimes they are keyed so they only plug in one way and sometimes they aren't. Even if they're keyed you can insert them the wrong way if you put a little effort into it. You always have to remember to plug them in so the black wires are next to each other.
    In old PCs, almost all of the chips ran directly off of the 5 volt rail. As a result the PSU delivers most of its wattage at 5 volts. There are three or four lines dedicated to the 5 volt rail. The other main rail is 12 volts. That was used primarily to run disk drives, motors, and fans. The two negative rails are bias supplies which only have to provide small amounts of current.

    USB (Universal Serial Bus) dirancang untuk menghubungkan peripheral seperti mouse, keyboard, scanner, kamera digital, printer, hard disk, dan komponen jaringan ke PC. Hal ini telah menjadi metode koneksi standar untuk scanner, kamera digital dan untuk beberapa printer. Lengkap pinout.
      
    Universal Serial Bus (USB) adalah sebuah spesifikasi untuk membangun komunikasi antara perangkat dan sebuah host controller (biasanya komputer pribadi). Sebuah sistem USB terdiri dari pengontrol host dan beberapa perangkat yang terhubung dalam mode seperti pohon menggunakan perangkat hub khusus. Hub dapat mengalir, hingga 5 level. Sampai dengan 127 perangkat dapat dihubungkan ke sebuah host controller tunggal. USB dapat menghubungkan peripheral komputer seperti mouse, keyboard, kamera digital , PDA , ponsel , printer, personal media player , flash drive, GPS , Adapter Jaringan, dan hard drive eksternal . Bagi banyak dari mereka perangkat, USB telah menjadi metode koneksi standar.

    Antarmuka USB ditujukan untuk menghilangkan kebutuhan untuk menambahkan kartu ekspansi ke komputer PCI atau PCI-Express bus, dan meningkatkan plug-and-play kemampuan dengan memungkinkan perangkat untuk menjadi panas bertukar atau ditambahkan ke sistem tanpa reboot komputer.

    USB konektor
    Ada beberapa jenis konektor USB. USB spesifikasi asli Standar-A dan-B Standar colokan rinci dan wadah. Nowdays ada 7 konektor USB dikenal: Standar-A, Standar-B, Mini-A, Mini-B , Micro-A, Micro-AB, Micro-B .

    USB pinout sinyal
    USB adalah serial bus. Ini menggunakan 4 kabel terlindung: dua untuk daya (+5 V & GND) dan dua untuk sinyal diferensial data (diberi label sebagai D + dan D-dalam pinout). NRZI (Non Kembali ke Nol Balikkan) skema pengkodean yang digunakan untuk mengirim data dengan field sync ke host dan menyinkronkan jam penerima. Dalam kabel data USB Data + dan Data-sinyal tersebut dikirimkan pada twisted pair. Tidak perlu terminasi. Half-duplex signaling diferensial membantu untuk memerangi efek kebisingan elektromagnetik pada baris lagi. Berlawanan dengan kepercayaan populer, D + dan D-beroperasi bersama-sama, mereka tidak koneksi simpleks terpisah.

    Transfer USB mode
    Serial bus Univeral mendukung mode Kontrol, Interrupt, Bulk dan Isochronous transfer.

    Transfer USB tarif: Kecepatan Rendah, Full Speed, Hi-speed.
    Bila perangkat baru pertama plugs, tuan rumah dan beban menyebutkan driver perangkat yang diperlukan untuk menjalankannya. Pemuatan driver yang sesuai dilakukan dengan menggunakan PID / VID (Product ID / Vendor ID) kombinasi disediakan oleh perangkat keras yang melekat. Pengendali host USB memiliki spesifikasi sendiri: UHCI (Universal Host Controller Interface), OHCI (Host Controller Interface Terbuka) dengan USB 1.1, EHCI (Host Controller Interface Ditingkatkan) digunakan dengan USB 2.0.

    USB mendukung empat kecepatan data:
    • Kecepatan Rendah (1,5 Mbit per detik) yang banyak digunakan untuk Perangkat Input Manusia (HID) seperti keyboard, m, joystick dan sering tombol pada perangkat kecepatan tinggi seperti printer atau scanner;
    • Full Speed ​​(12 Mbit per detik) yang didukung luas oleh hub USB, mengasumsikan bahwa perangkat membagi bandwidth USB antara mereka dalam dasar pertama datang pertama-melayani - itu mudah untuk kehabisan bandwidth dengan beberapa perangkat;
    • Hi-Speed ​​(480 Mbit per detik) ditambahkan dalam spesifikasi USB 2.0. Tidak semua perangkat USB 2.0 Hi-Speed ​​adalah.
    • SuperSpeed ​​(USB 3.0) kecepatan 4800 Mbit / s (~ 572 MB / s).

    Sebuah perangkat USB harus menunjukkan kecepatan dengan menarik baik D + atau D-garis tinggi sampai 3,3 volt. Ini menarik up resistor pada akhir perangkat juga akan digunakan oleh host atau hub untuk mendeteksi keberadaan perangkat yang terhubung ke port. Tanpa pull up resistor, USB menganggap tidak ada yang terhubung ke bus. Baru USB 3.0 standar, mendukung kecepatan diperpanjang 4.8Gbit per detik.
    Dalam rangka membantu pengguna untuk mengidentifikasi kecepatan maksimum dari perangkat, perangkat USB sering menentukan kecepatan di sampul dengan salah satu dari logo pemasaran USB khusus.

    USB Hi-speed perangkat

    Hi-Speed ​​perangkat harus jatuh kembali ke data rate lebih lambat dari kecepatan penuh ketika dicolokkan ke hub Full Speed. Hi-Speed ​​hub memiliki fungsi khusus yang disebut Penterjemah Transaksi yang mensegregasikan Kendali Kecepatan dan Speed ​​bus lalu lintas rendah dari Hi-Kecepatan lalu lintas.

    USB perangkat bertenaga

    Konektor USB menyediakan kawat 5 volt dari tunggal yang menghubungkan perangkat USB mungkin kekuatan sendiri. Segmen diberikan bus ditentukan untuk memberikan hingga 500 mA. Hal ini sering cukup untuk beberapa perangkat kekuasaan, meskipun anggaran ini harus dibagi di antara semua perangkat hilir hub unpowered. Perangkat bus-powered dapat menggunakan sebanyak kekuatan yang sebagaimana diizinkan oleh port itu terhubung ke.

    Bus-powered hub dapat terus mendistribusikan bus yang disediakan kekuatan untuk perangkat yang terhubung tetapi spesifikasi USB hanya memungkinkan untuk satu tingkat bus-powered perangkat dari bus-powered hub. Hubungan ini melarang dari hub bus-powered hub lain bus-powered. Banyak hub termasuk pasokan listrik eksternal yang akan perangkat kekuasaan terhubung melalui mereka tanpa mengambil daya dari bus. Perangkat yang membutuhkan lebih dari 500 mA atau lebih tinggi dari 5 volt harus menyediakan kekuatan mereka sendiri.

    Ketika perangkat USB (termasuk hub) yang pertama terhubung mereka diinterogasi oleh host controller, yang bertanya setiap persyaratan maksimum daya mereka. Namun, tampaknya bahwa setiap beban terhubung ke port USB dapat diobati oleh sistem operasi sebagai perangkat. Sistem operasi host biasanya melacak kebutuhan daya dari jaringan USB dan dapat memperingatkan operator komputer ketika segmen tertentu membutuhkan daya lebih dari yang tersedia dan mungkin menutup perangkat untuk menjaga konsumsi daya dalam sumber daya yang tersedia.

    Penggunaan daya USB:

    Bus-powered hub: Menggambar Max 100 mA pada kekuasaan dan 500 mA normal.
    Self-powered hub: Menggambar Max 100 mA, harus menyediakan 500 mA untuk setiap port.
    Daya rendah, bus-powered fungsi: Menggambar Max 100 mA.
    Daya tinggi, bus-powered fungsi: Self-powered hub: Menggambar Max 100 mA, harus menyediakan 500 mA untuk setiap port.
    Self-powered fungsi: Menggambar Max 100 mA.
    Suspended perangkat: Max 0,5 mA

    Dedicated modus pengisi daya:

    Sebuah pengisi daya USB sederhana harus singkat 2 baris data bersama-sama. Perangkat kemudian akan tidak mencoba untuk mengirim atau menerima data, tetapi dapat menarik hingga 1.8A, jika pasokan dapat menyediakan itu.
    USB tegangan:

    Tegangan yang diberikan oleh host atau port hub powered antara 4,75 V dan 5,25 V. drop tegangan maksimum untuk bus-powered hub adalah 0,35 V dari host atau hub ke port output hub. Semua fungsi hub dan harus mampu mengirim data konfigurasi pada 4,4 V, tetapi hanya fungsi-fungsi daya rendah harus bekerja pada tegangan ini. Tegangan operasional Normal untuk fungsi adalah 4.75 minimal V.
    Perisai kabel USB:

    Hanya perisai harus terhubung ke Ground di host. Tidak ada perangkat harus terhubung Shield untuk Ground.
    Kabel USB kabel:

    Terlindung:
    Data: 28 AWG twisted pair
    Daya: 28 AWG - 20 AWG non-twisted

    Non-terlindung:
    Data: 28 AWG non-twisted

    v 1.x dengan 20 pin konektor secara luas digunakan di motherboard PC. Digantikan oleh v 2.x dengan 24 pin konektor
    ATX spesifikasi meliputi tidak hanya Power Supply Unit, tetapi juga antarmuka untuk kasus dan motherboard. Selain lama AT standar, ATX 2.0 telah satu baris tegangan ekstra tersedia (3.3V), konektor berlapis rantai ke pin 20-tunggal dan daya pada kawat yang memungkinkan Software untuk mematikan PSU.

    Spesifikasi ATX membutuhkan catu daya untuk memproduksi tiga output utama, 3,3 V (± 0,165 V), 5 V (± 0,25 V) dan 12 V (± 0,60 V). Rendah daya -12 V (± 1,2 V) dan 5 VSB (siaga) (± 0,25 V) pasokan juga diperlukan. Sebuah -5 V output awalnya diperlukan karena disediakan di bus ISA, tetapi menjadi usang dengan penghapusan bus ISA di PC modern dan telah dihapus dalam versi standar ATX.

    Awalnya motherboard ini didukung oleh satu konektor 20-pin. Versi saat ini pasokan listrik 2.x ATX12V menyediakan dua konektor untuk motherboard: konektor 4-pin tambahan menyediakan tenaga tambahan untuk CPU, dan 24-pin ATX utama 2 konektor power supply, perpanjangan dari versi 20-pin asli .

    32-bit bus didefinisikan oleh PCMCIA.
    CardBus, the 32-bit high performance bus mastering architecture for PC Cards, was standardized by the PCMCIA in May 1996. CardBus, 32-bit tinggi kinerja bus menguasai arsitektur untuk Kartu PC, adalah standar oleh PCMCIA di Mei 1996. This bus is targeted to mobile computers. Bus ini ditargetkan untuk komputer mobile. PCI-like 32-bit interface operates at a power-saving 3.3 volts, and cards can include standardized power-management mechanisms. PCI-seperti 32-bit antarmuka beroperasi pada hemat daya 3,3 volt, dan kartu dapat termasuk standar mekanisme manajemen daya. The CardBus interface allows an I/O adapter or a memory module to be added to or removed without disrupting the system"s operation. It adds high bandwidth PCI-based capabilities to the PC Card technology. Antarmuka CardBus memungkinkan adapter I / O atau sebuah modul memori yang akan ditambahkan ke atau dihapus tanpa mengganggu sistem "s operasi. Ia menambahkan bandwidth tinggi berbasis PCI kemampuan untuk teknologi PC Card.
    CardBus PC Cards are attached to their host system through a sturdy 68-pin connector, which is common to all PC Cards. Kartu PC CardBus yang melekat pada sistem host mereka melalui konektor 68-pin kokoh, yang umum untuk semua Kartu PC. (CardBus cards employ a shielding shroud around this connector, to enhance their signal integrity). (Kartu CardBus menggunakan kain kafan perisai sekitar konektor ini, untuk meningkatkan integritas sinyal mereka).
    CardBus cards adopt the well-established PC Card form-factors. Kartu CardBus mengadopsi Kartu PC mapan bentuk-faktor. There are different types of CardBus cards (sizes are TxLxW): Ada berbagai jenis kartu CardBus (ukuran yang TxLxW):
    • Type I: 3.3mm x 85.6mm x 54.0mm Tipe I: 3.3mm x 85.6mm x 54.0mm
    • Type II: 5.0mm x 85.6mm x 54.0mm Tipe II: 5.0mm x 85.6mm x 54.0mm
    • Type III: 10.5mm x 85.6mm x 54.0mm Tipe III: 10.5mm x 85.6mm x 54.0mm
    CardBus provides a 32-bit multiplexed address/data path, which operates at PCI local-bus speeds of up to 33 MHz, yielding a peak bandwidth of 132MB/sec. CardBus menyediakan 32-bit alamat multiplexing / jalur data, yang beroperasi pada bus PCI lokal kecepatan hingga 33 MHz, menghasilkan bandwidth puncak 132MB/sec. CardBus accomplishes this by adopting the synchronous burst-transfer orientation of PCI, as well as a bus protocol, which is essentially identical to that of PCI. CardBus menyelesaikan ini dengan mengadopsi orientasi meledak transfer sinkron dari PCI, serta protokol bus, yang pada dasarnya identik dengan PCI.
