Universal multi-frekvens mottagare (kort distans)

Very compact size: 29x29x10mm.
Can be supplied from 5 to 36Vdc and from 7 to 27Vac.
Frequency selected by the user: 433.42, 433.92, 434.15, 434.42, 868.3, 868.5, 868.8, 315*, 288*, 300*, 303*, 306*, 310*, 318*, 330*, 390*, 403.55*, 418* MHz. Frequencies marked with * cannot be used inside UE. The frequency of the remote control must be stable, so it does not work with remote controls without crystal or saw resonator (some bad remote controls operating around 300 MHz)!
OOK (AM) and FSK (FM) modulation is supported: FM with 2 different deviation value, 12,5 and 25 KHz
Works with a wide range of remote controls which transmit fixed or rolling code. See the compatibility table.
Manages different types of remote controls in the same time.
It's possible to learn one or more "master remote controls" that can be use just to enable learning for 10s without the need to access the receiver to press the Prog button.

creRec12_200

This very small device, only 29x29x10mm, can be used with almost any radio remote control in the market which transmit in a frequency between 288 and 868 MHz.

It's very easy to be installed, using only two wires for the power supply and two opto-coupled wires which should be connected in parallel with the electronic board that should be remotely controlled.

The operating frequency, shown in the table, can be simply programmed using the Prog button, as like as the type of output which should be programmed as bistable, hold-to-run and as timer programmed from 250ms to 60 minutes.

In the same receiver it's possible to learn up to 60 different remote controls, even if different brand/model, both fixed and rolling code: the number of remote controls depends by the code complex, so, for example, it's possible to manage 40 KeeLoq rolling code remote controls.

When a known code is transmitted by the remote control, Creasol UniRec1 shorts the switch wires, simulating a pushbutton. The output is opto-insulated: maximum admitted current is 15mA and maximum voltage 40Vdc.

Creasol UniRec1 can be used to:

activate the "start" input of an electronic board used to open/close a gate, garage door, traffic barrier
activate an electronic device that is already controlled by remote controls operating in strange or dismessed frequency (418 MHz, 315 MHz, and so on...)
connecting an external relay, it's possible to use it to control an high power output, like courtesy light.

It's supplied in nice blister with instructions printed in several languages. We can also supply this device with customized instructions.

Installing instructions

creRec1_schema1

This device has 5 wires, one of which is used as antenna and should not be connected anywhere. Two wires should be connected to a power supply, usually provided by the operator board (typically 12 or 24Vac/dc). The remaining two wires should be connected to the input of the electronic board, in parallel to the existing switch (start button), as shown in the figure.

Check the voltage on the start button: it should be in the range 2÷40Vdc. Mark the positive pole.
Measure the current through the start button: it should be less than 15mA.
Connect the 2 wires marked as Supply to a power supply: don't care about polarity.
Connect the wire Switch+ to the positive pole of the start button, and the wire Switch- to the negative pole of the start button.
Configure the frequency you wish to use, pressing Prog button for 5 times: LED shows the current programmed frequency, for example it flashes twice to indicate 433.92 MHz. Then press again Prog button N times, as indicated in the frequency table (for example 3 times for 868.3 MHz)
If the remote controls uses FM modulation, press Prog button 9 times, wait for led flashes, then press Prog button again for 2 or 3 times, to set modulation to FSK 12.5 or 25 KHz. Look at the compatible table below to know how to program this parameter for your remote controls.
Configure the output type, pressing Prog button 6 times: LED flashes to indicate the current configuration. Press Prog button again to set the output type, for example 4 times to set it as 250ms timer.

Learning remote controls

Press the Prog button twice to enable learning mode: then it's possible to press a button on the existing remote control, within 10s, to learn it. Every time a new code is learned, the 10s timeout is reload.

LED flashes 2 times if the remote control has been learned, 3 times if it was already learned, 6 times if memory is full.

Removing remote controls

Press the Prog button 3 times, then it's possible to transmit, within 10s, from the remote control that need to be removed: LED flashes 4 times indicating that the remote control has been removed.

Alternatively, to blank memory (remove all remote controls), press Prog button for 10 times, LED flashes 10 times, then press again Prog button 3 times.

Learning "master" remote controls

Press the Prog button 4 times and follow the same procedure to learn remote controls: in this case it's possible to learn one or more "master" remote control, which can be used only to enable the learning procedure remotely, without the need to press the Prog button. Note that "master" remote controls do NOT activate the receiver output.

To learn new remote controls in this way, put the "master" remote control in trasmission for 1-2 seconds, then start to transmit for 1-2 seconds from the new remote controls: every time a new remote control is learned, the 10s timer is reload to permit successive learnings.
