RF Remote Control and Controller Applications

Wireless remote control devices are utilized to remotely operate various devices from a certain distance. The use of remote controls has become increasingly widespread and ubiquitous. Remote controls are utilized in a myriad of applications, ranging from automatic garage door openers to AC controllers, automatic light controllers, burglar alarms, and many other applications. Most of these controllers operate on the same principles of wireless communication..

Wireless remote controls

Various applications are used for this purpose when it’s about sending information wirelessly. However, Radio Waves and Infrared Waves are the most common. IR remote controls are most widely used in various household appliances. These household appliances generally include AC and TV.

On the other hand, RF remote controls are more popularly used in:

· Door remote controls

· Window remote controls

· Anti-theft alarming systems

· Car remote control, and more.

However, two types of coding are mainly used for wireless remote controls: fixed and learning codes.

What are the various coding modes available for the wireless remote control?

With the invention of intelligent life, people are now using wireless remote-control systems more frequently. The increasing use of wireless remote controllers in multiple applications has become a hot topic.

Different types of wireless remote controllers are available out there. The code mode of a wireless remote control makes it different from others. Currently, three of the most popular wireless remote controller types exist. These types include:

· Fixed code wireless remote controller

· Learning code wireless remote controller

· Rolling code wireless remote controller.

However, this article will mainly focus on the fixed and learning code wireless remote controller. Let’s look at the details below to understand the key differences between learning code and fixed code wireless remote controllers.

So, here we go:

An overview of fixed code wireless remote control

Typically, the fixed code wireless remote controllers adopt 2260 / 2262 / 2264 coding chips. It is always necessary to solder the remote control IC’s coding pins. Therefore, this type of remote controller is generally familiar as a fixed code remote. The data of this remote-control type features 6000 combinations.

On the other hand, the decoding chips of fixed code receivers are 2270 / 2272 / 2294. One fixed code receiver can equip with numerous wireless remote controllers. Fixed code remotes are most commonly used in applications that need a receiver to match different transmitters. These transmitters include lighting control, gate control, rolling shutter control, and others.

Currently, fixed code remote controllers are used in a variety of applications.

· Fixed code remote controllers are common in low-security occasion requirements.

· You can set the new controller to the same code if you want to increase the remote controllers’ numbers. Both new and old remote controllers will work at the same receiver simultaneously.

· In the case of the lost remote controller, you can set the same receiver with the new remote to a separate code.

Definition of a remote control for programming a device

The learning code controller typically uses 1527 / 2240 / 101 chip codes. Before using this type of remote controller, learning the code from the host is vital for the remote controller. You don’t necessarily need to open the shell for encoding. The learning code controller’s data generally have one million combinations. Therefore, the repetition rate in this type of remote controller is very low.

Consequently, it provides enhanced security than fixed code controllers.

MCU can decode the matched receiving chip with an already preset corresponding decoding program. The receiver of the learning code can accommodate 16 different remote controllers. Therefore, the common applications of learning code controllers are where it is essential to match multiple transmitters.

· The most common applications of learning code controllers include rolling shutter control, garage door, lighting control, etc.

· Users need a receiver to learn and store the new controller’s code to increase learning code capacity. Both new and old controllers can work with the receiver simultaneously. Typically, the receiver can store a dozen+ codes.

· In case of a lost controller, the user can delete the old remote’s code from the receiver. The lost remote will no longer connect to the receiver.

What is the difference between learning code and fixed code wireless remote controller?

Let’s look at the key differences between learning and fixed code remote controllers below. These differences will give you a clearer idea of which is better.

So, here we go:

Number of data combinations in learning code and fixed code

Firstly, the number of data combinations both provide is the key differentiator here. Learning code remote controllers can provide about a million data combinations. On the other hand, in the fixed code remote controller, there are about 6000 data combinations only.

Confidentiality and recode rate difference

When it’s to the recode rate, fixed code remote controllers typically have a higher recode rate than learning code remote controls. On the other hand, the confidentiality rate is higher in learning code remote controls. The encryption of fixed code remote controls is relatively lower than learning code controllers.

Different receiving chip parameters’ configuration

Learning code controllers are generally paired with their receiver chip to decode a single chip. The receiver can match with about 16 different remote controllers. On the other hand, a fixed code controller has to pair with a receiver of a 2270 / 2272 / 2294 decoding chip.

However, this receiver can then match dozens of different wireless remote controls.

The application field difference

Learning code remote controls are highly encrypted; therefore, the common applications of learning code are high-security. These applications typically include rolling shutter remote, garage door remote control, smart home controller, etc.

On the other hand, fixed code remotes are common in applications such as road gates, telescope door control, and more.
