Introduction:

this device, very compact and easy to be installed, has an opto-insulated
output which permits to control any electronic board with a low-voltage input by
almost any remote control in the market transmitting in the range 288÷868.8 MHz
with OOK (AM) or FSK (FM) modulation and good frequency stability (using crystal
or SAW resonators). It implements a power saving system that enables the receiver
only for a short period, in order to reduce the current consumption and the power
dissipated.

Installation:

this device has 5 wires, one of which is used as antenna and should not
be connected anywhere. Two wires, marked as Supply, should be connected to the
power supply 7÷30Vdc or 5÷24Vac. Two wires, marked as Switch+ and Switch-,
should be connected to the input (now called start button) of the existing electronic
board , as shown in Fig. 1.
1. Check the voltage on the start button: it should be in the range 2÷40Vdc. Mark the
positive pole. Do not use this receiver if start button is supplied by alternating
current!
2. Measure the current through the start button: it should be less than 15mAdc.
3. Connect the wires marked as Supply to the 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. Configure the device (frequency, output type, power saving) if needed.
6. Learn one or more remote controls, following the instructions below.

Configuration:

this device is supplied pre-configured to receive at 433.92 MHz,
OOK, and to activate the output for 500ms. To modify this configuration, press
quickly button Prog a number of times corresponding to the parameter to modify:
LED will flash to notify the current value of that parameter. Then, press again button
Prog for the number of times corresponding to the desired value, as specified in the
table. If programming fails, a long flash will be emitted.

Learning remote controls:

press the Prog button twice to enable learning mode: then
press a button on the remote control within 10s to learn it. Every time a new code is
learned, the 10s timeout is reload. Led flashes twice if the code is learned, 3 times if
was already learned, 6 times if memory is full.

Removing remote controls:

press the Prog button 3 times, then press button on
remote controls in the same way as learning procedure. Led flashes 4 times for any
removed code. To blank the whole memory, press the Prog button 10 times, wait for
Led flashing, the press Prog button 3 times.

Learning master remote controls:

press the Prog button 4 times, then press button on
remote control: this remote controls will not activate the output, but can be used to
enable learning procedure without the need to access the receiver and press Prog
button. 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.

Security and safety:

do not use with systems that require a high level of anti-theft
security. Installation should be done by a qualified technician, in a well insulated
enclosure, protected by dust, high humidity, steam and contact with other circuits and
metallic parts. All responsibility, for any damage caused by not complying with the
instructions in this manual, is declined.

Warranty:

the warranty complies with statutory requirements, and cover only defects,
within the product itself, in material and manufacture. Your local stockist should be
contacted in connection with any warranty-related matters. Your warranty entitlements
only apply to the country in which the device was purchased.
