Creasol UniRec1: universal multi-frequency receiver, 1 channel

Universal receivers

This is a small universal receiver, only 41x31x11mm, that can be used with almost any radio remote control in the market which transmit in a frequency between 224 MHz and 868 MHz, AM and FM, fixed and rolling codes.

Also, it can receive in one or two different programmable frequencies, even with different modulations.

When a valid code is received, it activates an optoisolator that let the current flow from Switch+ to Switch- wire: it's designed to control an electronic board (gate opener, for example) with a low voltage (40Vdc max) pushbutton input.

It's very easy to be installed:

connect the two wires marked as "Supply" to the power supply
connect Switch+ wire to the positive terminal of the pushbutton input
connect Switch- wire to the negative terminal of the pushbutton input

Use a common tester to measure voltage on the input terminal blocks of the controlled electronic board, to assure that voltage is lower than 40Vdc and current is less than 50mA.

Note: in case that the electronic board pushbutton input uses alternate current, you have to choose UniRec12 receiver (that is able to control 1 DC input + 1 AC/DC input) or UniRec2 receiver (that uses 2 relays, so it can control two AC/DC/110/230V input/output).

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 or timer from 250ms to 60 minutes.

In the same receiver it's possible to learn up to 1000 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 600 KeeLoq rolling code remote controls.

When a known code is transmitted by the remote control, Creasol UniRec1 shorts the SW wires, simulating a pushbutton. The output is opto-isolated: maximum admitted current is 50mA and maximum voltage 40Vdc.

In case that new remote controls are needed, we suggest to use our FourST (433.92MHz only) or MultiST (433.92 and 868.3 MHz) remote controls: long range, very stable, light-weight and soft-touch!

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...)
enhance the number and type of remote controls that can be used with a gate or garage door opener, by using different brand of existing remote controls even if they transmit in different frequencies
activate a switch/pushbutton input even in electronic boards that originally did not include a wireless control, using almost any remote control in the market.

Installing this receiver it's possible to:

open your garage door using both original remote controls and new remote controls, even if they transmit in different frequency/modulation;
use the remote control associated to the home garage door to open also the holiday garage door and pedestrian gate (using Creasol UniLock receiver, in this case);
add a wireless control to an electronic board with a lowvoltage pushbutton switch.

The product is made in Europe, provided in a nice transparent resealable recyclable clamshell, with instructions printed in several languages.

Features

Permits to control, by a wireless radio remote control, an electronic board with a low voltage DC input, 40Vmax, 50mA max
Very compact size: 41x31x11mm
Can be supplied from 7 to 36Vdc and from 7 to 27Vac. Uses a DC/DC converter to get a low power consumption and dissipation
Already have 5 wires, 20cm long, for easy wiring:
- 1 antenna wire, that should be cut to 17cm (for 433-434MHz) or 8cm (for 868MHz), and should stay flat, horizontal or vertical
- 2 supply wires, that should be connected to 7-36Vdc or 7-27Vac: don't care about polarity
- 2 output wires, positive and negative (polarity is important)
Frequency selected by the user: 433.42, 433.92, 434.15, 434.42, 868.3, 868.5, 868.8, 315^*, 224.500*, 224.750*, 270*, 280*, 284*, 286*, 287*, 288*, 289*, 290*, 292*, 300^*, 302*, 303^*, 306^*, 310^*, 318^*, 330^*, 340*, 390^*, 403.55^*, 418^* MHz. Frequencies marked with ^* cannot be used inside EU. 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 values, 12 and 24 KHz; AM with standard and narrow bandwidth (higher sensitivity)
Twin frequency receiver: the user can select a single receiving frequency (for example only 433.92MHz OOK or 868.8MHz FSK), or two frequencies/modulations (for example both 433.92 MHz OOK and 868.8 MHz FSK, or both 868MHz OOK and 315MHz OOK, or any combination of frequencies/modulations).
Works with a wide range of remote controls which transmit fixed or rolling code. See the compatibility table below.
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 programming/learning for 10s without the need to access the receiver to press the Prog button. In this way it's sufficient to push the button on the "master remote control", then push button on one or more new transmitters (fixed or rolling code) to automatically program them to the receiver.
