PRODUCT DESCRIPTION

SMXI and SMXIS are 4-channel radio receivers for control units equipped
with SM-type connector. The peculiarity of compatible transmitters is that the
identification code is different for each transmitter. Therefore, in order to allow
the receiver to recognise a determined transmitter, the recognition code must
be memorised. This operation must repeated for each transmitter required to
communicate with the control unit.
Notes:
– Up to a maximum of 256 transmitters can be memorised in the receiver . No
one transmitter can be cancelled; all the codes must be deleted
– For more advanced functions use the appropriate programming unit .
TABLE B1 - Mode I memorising (All buttons are memorised on the related receiver output)
01. Press and hold down the receiver button for at least 3 seconds
02. Release the button when the Led lights up
03. Push, for at least 2 seconds, any of the buttons of the transmitter to be memorised within 10 seconds
Note – 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. The memorisation phase finishes if no new codes are received
for 10 seconds .
TABLE B2 - Mode II memorising (A specific receiver output can be associated to each button)
01. Press and release the receiver button as many times as the number of the desired output (Once for output No. 1,
twice for output No. 2)
02. Check that the LED emits the same number of flashes as the desired output, repeated over 10 seconds in regular
intervals (1 flash if output No. 1, 2 flashes if output No. 2)
03. Within 10 seconds press the desired button on the transmitter to be memorised, holding it down for at least 2 seconds.
Note – 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. The memorisation phase finishes if no new codes are received
for 10 seconds .

INSTALLING THE 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 50-Ohm impedance (e.g. low dispersion RG58), the cable
must be no longer than 10 m.
If the aerial is installed in a place that is not connected to earth (masonry struc-
tures), the braid's 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.

MEMORISING A REMOTE CONTROL
WARNING – When the memorisation phase is activated, any tran smitter
correctly recognised within the reception range of the radio is memo-
rised. Consider this aspect with care and remove the aerial if necessary
to reduce the capacity of the receiver.

The receiver features 4 outputs, all available on the underlying connector. To
find out which function is performed by each output, see chapter 6.1.
During the transmitter code memorisation phase, one of these two options may
be chosen:
Mode I - Table B1: Each transmitter button activates the corresponding out-
put in the receiver, that is, button 1 activates output 1, button 2 activates out-
put 2, and so on. In this case there is a single memorisation phase for each
transmitter; during this phase, it doesn't matter which button is pressed and
just one memory sector is occupied.
Mode II - Table B2: Each transmitter button can be associated with a particu-
lar output in the receiver, e.g., button 1 activates output 2, button 2 activates
output 1, and so on. In this case, the transmitter must be memorised, pressing
the required button, for each output to activate. 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.
The procedures for memorising the remote controls must be performed within
a certain time limit; please read and understand the whole procedure before
starting.
In order to carry out the following procedure, it is necessary to use the button
located on the box of the radio receiver (reference A, Fig. 1a), and the corre-
sponding LED (reference B, Fig. 1a) to the left of the button.
