Cable Description Page

cable description

Want to make sure that you are using the correct cable when connecting to a projector, document camera or computer?  With so many cables and with so many different devices it is important that know the names of the different cables and what their purpose is.  Below you will find an image and a brief description of each of the regularly used cables.  Have a cable that is not listed and you are not sure how to use it?  Feel free to contact Paulina Villalobos or the Information Technology department for help.

VGA Cable (also referred to as a RGB cable)

This cable is what connects your document camera or computer to a projector so that you can display the image.  A VGA cable is necessary only for the image and does not work to transfer sound or data.  On newer computers and on many Apple computers the use of a VGA cable requires a converter or the use of HDMI (see below).  VGA cables come in a variety of colors but most in our district are black with a blue end like the one below.

A VGA cable only fits one way on the VGA Input but can work with or without tightening the two small screws on the side.  It is important to notice that the image on the cable and the input should be the same to recognize a VGA input.

HDMI Cable

The HDMI cable is the upgraded version of the VGA cable.  It is used to transfer a higher quality image but does not transfer sound or data.  Many new computers and monitors come standard with HDMI but most of the current equipment in our district still use VGA.  HDMI cables will only fit in the input one direction.

USB Cable

The USB Cable is the most commonly used cable for transferring data between a computer and another device.  The USB cable is required to be able to scan test documents when using Illuminate.  There are actually two different type of USB cables.  The original has a square end that connects to the device and the rectangular USB end that connects to the computer.  Newer USB 2 cables are slanted on each side and smaller than the original USB cable.  Pictures of both of these cables are below.

iPad Syncing Cables

There are two different versions of the iPad Syncing Cables that are used for both charging and transferring data to an iPhone or iPad.  These cables are not interchangeable.  The larger end was used on older devices while the newer lightening plug is on more current devices.  Be sure to not lose your original cables since extra cables usually have to be ordered for replacement for an aftermarket vendor.

Computer Power Cable

These cords are needed to provide power to most desktop computers and projectors but can be interchanged with other equipment.  They are always black in color and have the angled end like the picture below.  If you computer stops working for any reason it is important to always make sure the power cord is securely attached and plugged into the wall.

Laptop Power Cord

There are many different combinations of the power cords used for laptop computers but they all have both the regular power cord and then a small converter box.  Normally the end that plugs into the computer is small and round.  There are many different sizes of the round plug so be sure not to lose or mix up your cords like this.  Power cords for many document cameras and other technology look similar but will most likely not work with your laptop computer.

Ethernet Cable

Probably the cable that everyone needs but can't be found.  This is the cable that connects from your computer to a port on the wall so that you can access the Internet.  In our district, these cables are almost always bright yellow but sometimes are grey or black.  These are most often described as a large phone cable (although those aren't as common).
