Installation
Transmitters
The SM2 and SM4 transmitters (Fig.1) are ready to use. To check they work
properly, simply press one of the keys and check that the red LED flashes,
indicating transmission.

Contact in receiver output
The outputs are commanded by a relay with a normally open "NO" contact. If a normally closed "NC" type of contact is needed: disconnect the power supply from the
receiver, open the box, first from below as shown in Fig.5a and then from above as shown in Fig.5b, carefully remove the board and work on the welding side of the
receiver as follows:
1. Cut the part of the track at point X (Fig. 6).
2. Join the pads in point Y with a spot of solder (Fig. 6).
Aerial
The receiver requires an ABF or ABFKIT type aerial to work properly; without an aerial, the range is limited to just a few metres. The aerial must be installed as high as possible; if
there are metal or reinforced concrete structures nearby you can install the aerial on top. If the cable supplied with the aerial is too short, use a coaxial cable with 52-Ohm impedance
(e.g. low dispersion RG58); the cable must be no longer than 10m. Connect the central core of the cable to terminal 2 and the earth braid to terminal 1 (in the aerial terminal of
Fig.4). If the aerial is installed in a place that is not connected to earth (masonry structures), the braid terminal can be earthed to provide a larger range of action. The earth point
must, of course, be local and of good quality. If an ABF or ABFKIT aerial cannot be installed, you can get quite good results using the length of wire supplied with the receiver as
the aerial, laying it flat and connecting it to terminal 2.
Programming
In order to allow the receiver to recognise a given transmitter, the code must be memorised. This operation must be repeated whenever a new transmitter is required to
be inserted.
to a maximum of 256 transmitters can be memorised in the receiver. No one transmitter can be cancelled; all the codes must be deleted. To
memorise the transmitter code, chose one of the following two methods:
Modo I. In this case, there is a single memorisation phase for each transmitter; it doesn't matter which button is pressed during this phase. Each transmitter occupies a single
memory section. Each transmitter button activates the corresponding output in the receiver, that is, button 1 activates output 1, button 2 activates output 2, and so on (Fig.7a).
Modo II. Each button of the transmitter can be associated with a particular receiver output, e.g.: button 1 activates output 2, button 3 activates output 1, etc. (Fig.7b). In this
case, the transmitter must be memorised by selecting the required output and pressing the associated button. Naturally, each button can activate just one output while the same
output can be activated by more than one button. One memory section is occupied for each button.
!
During the memorisation phase, any transmitter correctly recognised within the reception range of the radio is memorised. Consider this aspect with
care and remove the aerial if necessary to reduce the capacity of the receiver. The memorising phases must be performed within a certain time limit; please read
and understand the whole procedure before starting. To activate memorisation, press the button and follow the indications of the LED on the receiver box (Fig.2).
Memorising a transmitter in mode I (each button activates the corresponding output in the receiver).
1. Press and hold down the receiver button for at least 3 seconds
2. Release the button when the led lights up
3. Within 10 seconds press any button on the transmitter to memorise for at least 2 seconds
N.B.: If the procedure was memorised correctly, the Led on the receiver will flash 3 times. If there are other transmitters to memorise, repeat step
3 within another 10 seconds, if not, the memorisation phase will finish automatically.
Memorising a transmitter in mode II (each button can be associated with a particular output).
1. Press the button on the receiver a number of times equal to the output required (e.g.: twice for output N° 2)
2. Check that the led flashes for a number of times equal to the selected output. (e.g.: 2 flashes for output N° 2 )
3. Within 10 seconds, press the required button on the transmitter to memorise for at least 2 seconds
N.B.: If the procedure was memorised correctly, the Led on the receiver will flash 3 times. If there are other transmitters to memorise for the
selected output, repeat step 3 within another 10 seconds, if not, the memorisation phase will finish automatically.
Memorising a remote transmitter
It is possible to memorise a new transmitter without using the button. A previously enabled and working remote control is required. The remote
controls are called "NEW" for the one to enter, and "OLD" for the one already memorised. The "NEW" transmitter will "inherit" the same
characteristics as the "OLD" one, therefore, if the "OLD" transmitter was memorised in I the "NEW" one will also be memorised in mode I.
Vice-versa, if the "OLD" one was memorised in mode II, in this case, the correct buttons must be pressed on the two transmitters.
1. On the NEW transmitter: Press the button for at least 5 seconds, then release.
2. On the OLD transmitter: Press and slowly release the button 3 times.
3. On the NEW transmitter: Press and slowly release the button once.
N.B.: if there are other transmitters to memorise, repeat all the above steps for each new transmitter
Deleting all transmitters This procedure cancels all the codes contained in the memory.
1. Press the receiver button and hold it down
2. Wait for the led to light up, for it to switch off and then wait for it to flash 3 times
3. Release the button exactly during the third flash
N.B.: if the procedure was performed correctly, the led will flash 5 times after a few moments.

Receiver
The SMX2 receiver (Fig.2) is for universal use. Box provides the circuit with
essential and effective protection and can be fixed using the adhesive on the
bottom or with screws.
Voltage limits: 18 ÷ 24 V
Voltage limits: 10 ÷ 18 V
Red= Positive, Black= Negative. Position is not important if alternating current is selected
