How to correctly select the wireless remote control and a few common errors
Source: | Author:cj36 | Published time: 2017-05-13 | 266 Views | Share:
Wireless remote control for many new people, are not very understanding, that is because they do not understand, often there will be a variety of problems, such as the purchase of a wireless remote control does not match? How far are you remote? Do you have garage doors there, electric door wireless remote control? And so on. For these questions Chen Jie tell you how to correctly select the wireless remote control and a few common errors.

Wireless remote control

Choose a few remote errors common to the remote control:

1. Appearance: one of the common errors, many users in the original wireless remote control to match the new wireless remote control when mistakenly choose a look and the original wireless remote control exactly the same wireless remote control can be used, in fact, if so Match, most of the remote control can not replace the original remote control. In the choice of wireless remote control, select the same brand or four parameters (followed by a detailed wireless remote control selection method), remote appearance is not important.

2. Category: common errors in the second, many users often ask: Do you have a garage door where the wireless remote control? Rolling shutter wireless remote control Retractable door wireless remote control? Electric door remote control Car wireless remote control Alarm wireless remote control In fact, regardless of where the wireless remote control for the field, as long as the wireless remote control of the four parameters corresponding, followed by matching the right way, these wireless remote control can be shared, no need to sub-door wireless remote control and the like. In short, with a wireless remote control, parameter matching and matching method, the wireless remote control can be used in any field: cars, garage doors, shutter doors, curtain doors, roll gate, road gate, alarm, etc. can be used The

3. Distance: common errors of the three, many users often ask: how far you remote control distance? In fact, the wireless remote control distance and receiver module sensitivity is necessarily related to the wireless remote control can not be how far away. In general, the same receiver module, the greater the wireless remote control transmitter power, the farther away, the same wireless remote control, receiver module sensitivity and anti-interference ability, the farther away. Often said 50 meters wireless remote control or 100 meters wireless remote control, usually refers to the wireless remote control of the open distance, refers to the ideal environment, there is no interference environment, and the premise must have a matching receiver or for some with high sensitivity Receiver for the wireless receiver module.

For the above common errors, the correct wireless remote control selection method is as follows:

A, select the wireless remote control the same operating frequency (common frequency such as 433MHz, 315MHz)

B, select the wireless remote control chip model the same

Learning code HS1527, EV1527, HT6P20B and so on

Fixed code HS2260, HS2262, PT2264 and so on

Rolling code HCS301, HCS300, HCS200, etc. (if the HCS class rolling code also need brand consistency)

Docking: With copy remote control, can be used alone function

C, wireless remote control data (encoding) the same

D, wireless remote control waveform minimum pulse width of the same time.

If it is fixed code remote control, but also need to be consistent, if it is learning code, wireless remote control and the previous receiver to the code. If the original wireless remote control is a fixed code or learning code of the wireless remote control, you have no professional knowledge, it is recommended to select the copy wireless remote control. For how to operate the remote control, please refer to the operation of the remote control remote control.

See here, many users have doubts, I do not know my wireless remote control work frequency and coding chip ah! How to do? Please open your wireless remote control shell to see remote control internal circuit board:

A. frequency selection: see the wireless remote control circuit board on the resonator (some people also called crystal) on the figures (315MHZ? 433MHZ? Other 390,418, 430 frequency?), Select the same and the original wireless remote control The frequency can be.

B. Chip selection: IC on the remote control circuit board (2260? 2262? 2264? 1527? 2240?) General IC prefix is different, there may be differences in the oscillation resistance, but the IC suffix must be the same or compatible, such as 2260/2262 / 2264 Several chips are compatible, this is the fixed code is also called welding code (requires the user to self-welding custom coding). If it is 1527 or 2240, which is fixed code (no need to encode the chip factory code), so this type of remote control and the need to accept the motherboard to learn to match the code to use, so often called learning code.

C. wireless remote control data This is not intuitive, and need to copy the machine or equipment to see.

D. pulse width time, that is often said that the oscillation resistance, which is connected with the remote control IC pin connected to a resistance. Fixed code chip 2262/2264 commonly used oscillation resistance: 1.2M (125); 1.5M (155); 2.2M (225); 3.3M (335); 4.7M (475). The oscillation resistors of the learning code chip 1527 are often 180K (184) 270K (274); 330K (334) and the like. Oscillation resistance mismatch may cause the distance to be near, or if the wireless remote control receiver does not operate.

Wireless remote control

After reading the above description, want to give their own home wireless remote control more than a few remote control? Yes, then choose to copy / copy remote control can match, and very simple, just like a key with the same principle. Before choosing to use the copy remote control, first confirm your original remote control of the two important parameters: chip and frequency. All learning code, fixed code can be copied, part of the rolling code and brand can also be copied.

In addition to the above-mentioned copy / copy remote control can be matched, there is a way to others with remote control, the use of YET-9001 copy machine, just the original wireless remote control on the YET-9001 copy machine on Immediately show the four parameters directly, so you at a glance, a word cool. Can copy the original remote control, but also according to your motor brand regeneration of a new wireless remote control out, to solve your wireless remote control lost.
