Understanding Infrared with Xantech

Infrared technology has many applications in the modern world and chances are, you’ve used this technology most of your life. Xantech is one of the leading names in IR solutions, dealing mainly with the remote control of home electronics. Xantech provides installers and users with the hardware that they need to take control of any infrared-capable A/V or CFL-lighting setup. Infrared control has come a long way since it became the industry standard for wireless television remotes in the early 1980’s, so let’s take a look at what’s changed.

What is Infrared Radiation? 

Don’t let the “radiation” part of the name fool you. Infrared radiation is safe, unlike ultraviolet radiation. It can be emitted from sunlight and even humans in the form of heat. Infrared light is in the invisible portion of the electromagnetic spectrum and is a somewhat longer wavelength than red light, which makes it unseen by the human eye.

Back to the Basics: The Remote-Control System

In order to understand the benefits of Xantech’s IR products, it is important to understand the basics of infrared technology. Specifically, how IR remote controls and infrared radiation work together.

In every remote-control system, there has to be a transmitter and receiver. The transmitter (example: a television remote) sends a signal and the receiver (often located on the front of a device) accepts and interprets the signals from the transmitter. On the transmitter, there is a light emitting diode, otherwise known as an LED, that produces infrared light signals. The receiver contains a photo diode that takes in the infrared light signals and interprets them through the device’s microprocessor to turn the signals into outputs; such as, turning up the volume, changing the channel, turning the power on or off and many more actions. Xantech’s IR emitters and receivers offer a solid reception between devices that allows for endless control from just one remote.

A transmitter with an LED sends infrared signals to a receiver using patterns of flashing IR light. Think of it like Morse code. The transmitter’s LED flashes very quickly, making patterns of small, fast flashes of light. The photo diode picks these up and the microprocessor is able to decode the pattern of light. The microprocessor then tells the device to perform the desired action. Xantech has engineered a way for one transmitter (remote) to communicate with several different A/V and lighting components by having one central receiver that takes those IR inputs and then distributes them to a number of IR transmitters that communicate with each component.

Range 

In early IR applications, there had to be a clear line of sight between the transmitter and receiver. If there was not, the light signal would be incomplete or lost altogether. Xantech has spent years honing their IR technology to provide better versatility and usability. The range of the transmitters and receivers depend upon the strength of the signal coming from the transmitter. The size of the photo diode receiving the signal also affects the range. If the transmitter has multiple LED’s or a particularly strong LED then there will be a more powerful signal. There was an estimated 30-feet of clear-sight range for early IR devices.

With Xantech’s DinkyLink 85/Green and 95/Red Series IR Receiver Kits, users can decide what distance is ideal for them—either way, it’s a lot more than 30-feet. The 85/Green Series receivers offer up to 80-feet of range with standard A/V remotes. These are best for living rooms, family rooms, master bedrooms and anywhere in the general area of the A/V system that is being controlled. The 95/Red Series receivers allow up to 120-feet of range. These are ideal for use in large rooms, large family or kitchen areas, conference rooms and classrooms. Anywhere that requires superior performance and extended range is good for the Red Series. Both series allow for control over nearly any A/V system like TV’s, stereo systems, DVD players and even CFL lighting.

Customization

 Xantech not only offers solutions for different ranges of receivers, but also mounting locations and colors. This offers your customers the maximum amount of customizability for their setup. Options include an in-ceiling mounted peephole-style Micro Link IR Receiver Kit for lighting or projectors, surface-mount DinkyLink Kits for mounting on the top/bottom of TV’s with black, silver and white color options, and Hidden Link CFL/LCD Shelf-Top IR Receiver Kits for discreet installs. The Designer Blink Emitter is an accessory that connects to a Xantech Connecting Block via a 3.5mm mono cable or to the Dinky Link IR Receivers. The Connecting Block acts as a splitter has the ability to send signals to multiple Blink Emitters. Those Blink Emitters then send signals to various A/V components to provide interconnectivity in a multi-unit A/V system. Even if the system is in a cabinet or out of sight on a shelf.

Connecting the Dots

IR technology has grown immensely since its introduction into the consumer electronics industry. Xantech is a prime example of what that growth looks like. Xantech offers IR solutions that give customers superior performance, interconnectivity and reliability that can be lacking in other connectivity and remote-control products.
