Extend USB cable over 12 meters Troubleshooting


Introduction This article explains how to extend a USB cable away than the standard 5 meters and a Web camera to function properly. I lengthen a cable exceeding 12 meters and get to work properly USB sticks, printers and Wireless USB. To be able to run Web cameras had to use a powered USB hub between the camera USB cable and UTP as these require more power (which is lost by extending the cable) to operate.

The idea came after mounting a surveillance system and know the cost of IP cameras, capture cards, CCTV cameras, etc. The cost of setting up a monitoring system using these cameras is quite high. So I started searching the Internet about the ability extend the distance of a Webcam USB cable without affecting the operation of this for use with ZoneMinder . I found this site (in English) where possible and commented that explain how to do it by cutting a USB extension cable (male connector on one end and female on the other) in half. I decided to make an extension using USB connectors instead of cutting a cable because I read several pages that worked better. Then explain

create a USB extension. Material


necessary
  • UTP Cable USB connector 1 female and 1 male for every wire you wish to extend
  • Cautín and welding tube or sheath
  • shrink (optional) for connecting the cable to the USB connector Black Belt

Procedure:

The cable / USB connector consists of 4 pins, 2 for and 2 for current data. Pin 1 and 4 are used for current and 2 and 3 for the data shown in the following table:
 Pin Name Cable color Description 
1 VCC Red +5 v
2 D-White Data -
3 D + Green Data + 4 GND Black Ground

Considering the above table, what will be done is to weld orange-white wires and Orange UTP cable in the USB connector Pin 1. The white-green on Pin 2, Pin 3 green and the rest (coffee, white, brown, blue and white-blue) on Pin 4. As shown in the following table:
 
PIN USB 1 COLOR white and orange-orange-green
2 white 3 green

4 others (blue, white, blue, brown, white-brown)
If you want to use USB cable cut in half instead of the connectors are soldered wires as follows: UTP USB PIN
 
white 1 red-orange and orange
2 white 3 white-green green green

4
rest white
First cut a piece of shrink sleeve and placed inside each end of the cable. Then separate UTP cables and peel the ends.

then soldered the wires on each USB connector as described above:

Then, put the heat shrink sleeve on the cable is exposed and heated copper to cover it.

proven to work: Once a soldier

connectors connect a Web camera to the newly created and this extension to a computer, but marked a recognized her error. Then I connected a memory USB and this worked well, you can access and copy files in it. Then I tried a printer, a Wireless USB device and a digital camera to download photos. Everything worked fine except the webcam. Then I bought a powered USB hub and place it between the CPU and the extension by dialing the same error when connecting a Web camera. But to place the USB hub between the webcam and the WebCam USB extension worked.

This extension of more than 12 meters working properly I have a USB camera with Zoneminder. In the hub I can connect more cameras, I can even connect any USB device you want.

Conclusions:

Based on the tests we can conclude that the USB cable to extend beyond 5 meters, this is not capable of providing enough voltage to run a webcam. It is therefore necessary to provide electricity somehow. One way is with a powered USB Hub.
