New Reversible USB Connectors Will Carry High Resolution 4K Video & Audio

The upcoming USB cable’s high-powered abilities, but now audio and video have joined the mix. Working alongside the USB 3.0 Promoter Group, the Video Electronics Standards Association (VESA) has leveraged a Display-Port “Alt Mode” to sort full audio/video on monitors with resolutions of 4K and above with the Type-C connector technology. What’s more, with the help of an adapter or converter cable, the new standard causbn be made to play nice with regular Display – Port, HDMI, DVI and VGA Jacks on existing displays. To wrangle video and sound, the alternate mode leverages a couple of the Type-C connector’s so-called Super-Speed lanes to deliver the goods to that external monitor — leaving the others to data transfers alongside that 100 watts of power. Of course, Display-Port tech has been available in Thunderbolt cables/jacks for some time, but the new USB kit looks to be “a single-cable solution” that’s sure to clean up that mess of wires under your desk.

USB Connector Type – C

It was announced in April and the connector was supposed to be finalized and revealed in July, but nothing has been heard from it every since.

Type-C connector and the USB 3.1 standard is the technology I’m most interested and excited about right now, followed by H.265, Wigig, SATA Express, DDR4 and super efficient, yet powerful ARM and Intel CPUs.
It’s supposed to be:

  • About the size of microUSB
  • Reversible and sturdy like Lightning
  • Nice click to it and tapered around the corners, like Lightning
  • Same plugs on both ends

If it’s really as they promised and takes off, it could replace USB Type-A, B, mini and micro, the hideous USB 3.0 micro-B.

USB 3.1 delivers 100W, so the connector could be adopted to power laptops, a universal charger. It’d also allow for much slimmer Ultrabooks and Laptops.

It could become THE connector and finally replace mini and micro USB to charge and connect various electronics; be it cameras, mice, keyboards, dashcams, even to charge quadcopters and other RC.

Next USB Connector Will Be Thinner, Reversible | Type-C connector USB 3.1

As mobile devices get increasingly slimmer, so too will their corresponding USB connectors. 



Development for the next-generation USB connector, called the Type-C, is underway and will be thinner and sleeker than current USB 3.0 cables (pictured above), according to the USB 3.1 Promoter Group, which is made up of industry heavy hitters including Microsoft, Hewlett-Packard and Intel.

To pack the powerful punch of the USB 3.1 standard, which can move data at 10 gigabits per second, into a smaller cable, it will closely resemble the USB 2.0 Micro-B. But it has a few advantages over existing models: Specifically, it’s reversible, meaning users no longer need to worry about plug orientation. The plug design is similar to Apple’s Lightning cables and will take away one of USB’s main frustrations. The downside is that the new cables won’t work with existing connectors. 

The Type-C connector is built on existing USB 3.1 and USB 2.0 technologies and will have scalable power capabilities, meaning it will be able to charge a wide range of gadgets. But it has a few advantages over existing models: Specifically, it’s reversible, meaning users no longer need to worry about plug orientation.

“While USB technology is well established as the favored choice for connecting and powering devices, we recognize the need to develop a new connector to meet evolving design trends in terms of size and usability,” said Brad Saunders, USB 3.0 Promoter Group Chairman, in a statement. “The new Type-C connector will fit well with the market’s direction and affords an opportunity to lay a foundation for future versions of USB.”

The organization said the Type-C connector will be completed by mid-2014.

RS232 Standard

  • It is a standard of the interface between a DTE and DCE.
  • Originally issued in 1962 as the RSA-232 standard.
  • It has been revised many times.
  • Now the most recent version is known as EIA-232-D, that is it comes from the Electrical Industries Association (EIA), Standard number 232, revision D.
  • It defines mechanical, electrical & functional characteristics of the interface.
  • It is a 25-wire cable terminated at one end with a male  connector and at the other end of a female connector.
  • Male connector at the end of DTE and female connector at the end of DCE.
  • The D-type connector may be a 25 pin or 9 pin connector.

DTE (Data terminal equipment) is any device that acts as a source or destination of binary data. Eg: Computer, printer etc. DCE is the intermediary device between the DTEs. DTEs do not often communicate directly with one another. So DCEs are necessary.

DCE (Data circuit terminating equipment) are the devices that transmits or receives data in the form of analog or digital signal through the network. Eg: Modems. DTEs  generates digital data and passes it to the DCE; DCE Converts the data to a form acceptable by the communication link And sends the signal to another DCE. The second DCE takes the Signal, convert it to a form usable by its DTE & delivers it.
