8 questions and answers on remote controls

1. What is a remote control for the gate operator?

Each remote control is simply a radio wave transmitter that sends an encoded signal to a radio card on the receiver that decodes it.

2. What are the ordering options?

The possibilities are almost unlimited! With a remote control we can control our gate motorization, garage door, blinds, roller shutters. You can also open and close windows, turn on the light or sprinklers in the garden.

3. Why do manufacturers offer several types of remote controls?

Remote controls can have different parameters: frequency, radio wave type and code type. In addition, the manufacturer often offers us remote controls in various shapes, colors and sizes.

"Each remote control has 3 important parameters such as: frequency, type of radio waves and type of code.

4. I have an old remote, but I want to buy another one. Can I choose a model I like better?

Not always. We need a remote control and a device that we want to control to use the same frequencies and radio waves. For example, radio remote controls operate on 433 MHz, but they do not work on the same radio waves, so they are not compatible.

"Only remote controls that operate on the same frequency and radio waves are compatible.

5. Which remote control frequency should I choose?

Remote controls for portal drives usually use two standard frequencies - 433 MHz or 868 MHz. In the case of 433 MHz the range of the signal is higher, but it penetrates the walls more easily. It is recommended for remote controls that work with the transmitter behind a particularly thick wall. The frequency of 868 MHz is perfectly made for places where there is a lot of radio interference, the signal quality is superior 433 MHz transmitter.

"Choose the remote frequency that best suits your needs."

6. Can I control devices of different brands with a single remote control?

Yes. However, it is important to remember that not all devices are compatible with each other. If you already have a remote control for your garage door, you do not have to choose the same brand when buying the gate operator. All you need is an additional receiver, compatible with the remote control you already have.

"Motors should not be controlled with remote controls from the same manufacturers - the only requirement is that the remote control and receiver are compatible".

7. What is the difference between a rolling code and a fixed code?

The difference between a rolling code and a fixed code is the signal emitted by a remote control. In the radio system with the fixed code each press of the key causes the same signal to be transmitted. While in the case of the rotary code each press on the key causes the emission of the different signal. The signal changes according to the given algorithm. Using the fixed code causes the same code to be generated and received in the motor control cabinet. This is an unfavorable situation - for example if your neighbors use the remote controls on the same frequency you can open not only your gate but also theirs.

8. What type of code is more reliable?

The rolling code is a much more secure solution. Each time a remote control emits a different signal depending on the algorithm determined. The receiver is programmed in such a way that it foresees a subsequent signal from the transmitter. Each transceiver pair has its own coding algorithm. Devices operating on the 868 MHz frequency use billions of billions of combinations so there is no possibility of code repetition.
