DIGITAL RADIO CONTROLS WITH DYNAMIC CODES 433RC
Description
The 433RC Radio control system in "AM" consists of one or more transmitters and one or
more receivers which can be combined to meet the specific needs of the system.
The 433RC system uses a highly reliable encoding system guaranteed by the use of
dynamic codes. The code is changed for each encoding transmission through the use of
an encoding algorithm which only the receiver is able to recognise and therefore decide
whether or not the code transmitted corresponds to the original code. The generated code
is memorised in the receiver via radio. The receiver is able to memorise up to 300 different
codes. During the transfer stage the codes are memorised in a non volatile memory mod-
ule. As this is a system based on dynamic codes each code is processed individually by
the receiver.
Important
The transmitted code changes for each command (rolling code). If disturbance interrupts
the transmission, the receiver will wait for a different code, the relay can then only be
activated by first releasing and then pressing the transmitter channel button again.
Use
The 433RC radio control allows the remote activation of electrical and electronic appliances
with its best use in the following areas: automatic opening systems, alarm systems, and in
all systems which require remote control activation (without wires) using secret codes.

Receiver versions
Slot-in receiver card
Adaptor for outdoor installation
Memory module
This is extractable, furnished with a non volatile EEPROM type memory and contains the
transmitter codes and allows you to memorise up to 300 codes (300 channel buttons). The
programmed codes are maintained in this module even in the absence of power.
Receiver antenna installation
Minimum and maximum range of the radio controls. 'Range' is intended to mean the working
distance, measured in free space, between the receiver and the transmitter with the
antenna installed. The range is therefore closely linked to the technical characteristics of
the system (power and sensibility) and varies according to the characteristics of the site in
which the system is located. It therefore follows that to obtain the best results from the radio
control the receiver and antenna installation sites should be carefully chosen.
It is not possible to install 2 receivers at a distance of less than 1.5 mt. from each other.
It is good practise to position the receiver away from computer systems, alarm systems
and other possible sources of disturbance. (A bad choice of positioning could
compromise the performance of the receiver).
Antenna
The installation of the antenna is fundamental, connected to the receiver it represents the
reception point for the radio control.
When installing the antenna the following points should be observed:
- The slot-in receiver card is supplied with its own antenna which consists of a piece of rigid
wire 170 mm in length.
- As an alternative it is possible to connect a tuned antenna using a coaxial cable RG58
(impedance 50Ω) with a maximum length of 15 m. The antenna should be positioned out
of doors in the highest possible point, visible and away from metal structures.
Transmitters
The transmitter is pre-coded and is fitted with an integrated circuit which is programmed
in the factory with a unique identification number. All the code parameters are contained in
this integrated circuit (external memory modules are not required) thus making code
management more reliable and the system more secure.
The transmitter has an automatic shut down mechanism which cuts in after 25 seconds of
continuous use (this limits battery consumption).
Receivers
The receiver could be:
- a card inserted directly into an appliance which is designed to receive it.
- in a case (card + adaptor) fitted with a terminal board for outdoor use.
Channel 1 of the slot-in receiver card is an "open collector" while channel 2 is a NO-C contact
(binding posts 1-2 fig.5 det. "C1"; contacts 7-8 on the Molex connector)
In the outdoor version (fitted in a case) channel 1 is a NO-NC-C contact (binding posts 1-
2-3) and channel 2 is NO-C contact (binding posts 4-5): these contacts are available on the
adaptor card (fig.5).
The two channels can be selected using the jumper "S1" fig.5 and it is possible to associate
the two functions CH1 and CH2 with one of the four (max) buttons on the transmitter (see
fig. 3). The receiver has an incorporated 433 MHz RF module "R1" which is soldered to the
card.
Status led "L1"
Flashing rapidly: cancelling a single user
Flashing slowly: memorising a single user
Continuously lit: memory full
Functions
A. Memorising a channel
B. Cancelling a channel (via an associated radiocontrol)
C. Cancelling the entire user memory
D. Memorising ulterior channels via radio (without having to open the box in which
the receiver is housed)
ATTENTION! Before memorising the transmitters for the first time remember to cancel
the entire memory content.
CODE Nr.
L292.02
This product has been tried and tested in the manufacturer's laboratory,
during the installation of the product follow the supplied indications
carefully.
A- Memorising a channel (fig. 4a)
1) Keep button "P2" MEMO pressed down and the led "L1" will start to flash slowly
2) Press the channel on the transmitter which is to be memorised
3) Keep button "P2" MEMO pressed down until led "L1" starts to flash again
4) Release the button and the led continue to flash
5) Press the channel on the transmitter which is to be memorised again (same transmitter,
same channel. If the channel or the transmitter is different you will not be able to
memorise the channel.
6) End of the memory procedure. Led "L1" will remain lit for 2 seconds meaning that the
channel has been correctly memorised.
• It is not possible to memorise a user code that is already in memory: In this case when
the radiocontrol is activated (point 2) the led will stop flashing. The program will only work
again when button "P2" MEMO has been released.
• If the radiocontrol is not activated a second time within fifteen seconds the program will
automatically leave the memory mode without memorising a new user code.
• If a new user code is activated the first time and a different channel (with an already
memorised user code) is actived the second time, the program will automatically leave
the memory mode (because the two codes do not correspond) and the channel present
in the second transmission will be activated.
Note:Once you have entered the second part of the memorising procedure (point 4
onwards) you will have to complete the entire procedure. If you do not wish to memorise a
code which you have already transmitted wait for fifteen seconds without doing anything,
the led will switch off and the code will not be memorised. When the receiver's memory is
almost full the user search function can take upto one second to complete.
2 Buttons
4 Buttons
B- Cancelling a channel (fig. 4a)
1) Keep button "P1" DELETE pressed down and the led "L1" will start to flash rapidly
2) Press the channel on the transmitter which is to be cancelled
2 Channels
3) Led "L1" will remain lit for 2 seconds meaning that the channel has been cancelled.
Note: If the user which is to be cancelled is not found in the memory, the led will stop flashing
and will work again when button "P1" has been released.
If the button is released before a channel is activated the program will automatically leave
the memorising or cancelling mode.
C- Cancelling the entire user memory (fig. 4a)
1) Keep buttons (P1+P2) pressed down simultaneously for more than 4 seconds
2) Led "L1" will remain lit for the period of time required for the program to cancel all the
codes (about 8 seconds)
3) Led "L1" will then turn off meaning that the cancellation procedure has been carried out.
D- Memorising ulterior channels via radio (fig. 4b)
• Memorisation can be activated by radio (without opening the receiver container) if
jumper "J2" has been inserted (fig. 5).
1) Make sure that the jumper "J2" has been inserted in receiver.
2) Using a transmitter, in which at least one channel button "A,B,C or D" has already been
memorised in the receiver, press the button "MR" as shown in figure "4b".
Note: all the receivers within range when the channel button is pressed (and which have
at least one of the transmitter channel buttons memorised) will activate their signal
buzzer "B1" (fig. 5).
3) Press one of the channel buttons on the transmitter. The receivers which do not contain
that channel code will sound a five-second long "beep" and will then disactivate. The
receivers which contain the channel code will sound a one-second long "beep" and will
enter the programming mode.
4) Press one of the channel buttons on the transmitter which you wish to memorise; the
receiver will sound 2 "beeps" of half a second each after which the receiver will be ready
to receive another code.
5) To leave the programming mode wait for 3 seconds without pressing any buttons. The
receiver will sound a five-second long "beep" and will then exit the programming mode.
• When the memory is entirely occupied the buzzer will sound 10 rapid "beeps" and will
automatically leave the "programming via radio" mode. Led "L1" will remain lit on the
receiver. The same signal is given each time you try to enter "programming via radio"
when the memory is full.
