Creasol Rec1: short range micro receiver

Introduction

This very small device, only 29x29x10mm, can be used with remote controls like Creasol Multi and Creasol Four to activate gate and garage doors operators, as like as other electronic devices which have one low-voltage input connected to a pushbutton switch.

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, 433.92 MHz, 868.3 MHz or 315 MHz, 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 with time programmed from 250 ms to 15 minutes.

When the proper code is transmitted by the remote control, Creasol Rec1 shorts the supply wires, simulating a pushbutton. The output is opto-insulated: maximum admitted current is 15mA and maximum voltage 40Vdc.

Creasol Rec1 can be used to:

• activate the "start" input of an electronic board used to open/close a gate, garage door, barrier
• activate an electronic device that is already controlled by remote controls operating in strange or dismessed frequency (418 MHz, 306 MHz, and so on...)
• connecting an external relay, it's possible to use it to control an high power output, like courtesy light. The following application note shows how to connect a relay to the Creasol Rec1 output. Please note that relay is not needed to control electronic board inputs!

It's supplied in nice blister with instructions printed in several languages.

Installing instructions

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 boards (typically 12 or 24V ac/dc), and two wires should be connected, in parallel to the existing switch, to the input of the electronic board, as shown in the figure.

1. Check the voltage on the start button: it should be in the range 2÷40Vdc. Mark the positive pole.

2. Measure the current through the start button: it should be less than 15mA.

3. Connect the 2 wires marked as Supply to a power supply: don't care about polarity.

4. Connect the wire Switch+ to the positive pole of the start button, and the wire Switch- to the negative pole of the start button.

5. Initialize a new code on the device, as specified in Fig. 3: turn power OFF, press and hold the Prog button then turn power ON: LED starts flashing slowly. After 10 seconds LED will flash quickly for 5 times, indicating that the new code has been initialized. Release the Prog button.

6. Activate the duplication procedure on the remote control, then press the Prog button on the device to transmit the device to the remote control. Repeat the procedure on other remote controls, or start duplication from the programmed remote control to other empty remote controls.

Creasol Rec1 can be used with almost any remote control duplicator: we suggest to use it with Creasol Four, if only 433.92 MHz frequency is needed, or with Creasol Multi : in the latter case you can control more devices, even if they operates in different frequencies, for example you can use Creasol Multi for

1. your gate, at 418 MHz with Creasol Rec1 at 868.3MHz, on button 1
2. pedestrian gate, with Creasol Lock connected to the electrical lock, at 433.92 MHz, on button 2
3. garage door, at 433.92 MHz, on button 3
4. entrance door, at 868.3 MHz, with Creasol Lock, on button 4

Application note REC1_02: How to connect Creasol Rec1 or UniRec1 to a relay

When the receiver should be connected to a circuit that works at high voltage (230V courtesy light, for example) or high current, a Relay should be connected as shown below.
Please note that Creasol Rec1 or UniRec1 has an opto-insulated output that consists in a NPN transistor, where Switch+ is the collector and Switch- is the emitter.
For this reason, the external relay is not needed when the receiver output should be connected to a low-voltage/low-current input of an electronic board.
