DIGITAL RADIO CONTROLS WITH ROLLING CODES XRADO

Description
The XRADO 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 XRADO 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 module. 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 XRADO 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.

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 m from each other. It is good practise to posi-
tion 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:
- Both the receivers (Slot-in and Mini) are supplied with their 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 at least 25 seconds
of continuous use (this limits battery consumption).
Receivers
Warning! The receivers must only be powered by a safety power pack. The use of non
safety power packs could provoke damage to the system.
Slot-in receiver cards
(fig. 6)
Warning! The receiver cards must be sufficiently insulated from the parts of the host device
which are powered by the mains.
- The receiver card (printed circuit (CS1034) is inserted directly into an appliance which is
designed to receive and has the following electrical connections:
24V ac/dc between the contacts 3-4
The receiver cards are fitted with two relays, the outputs of which are marked CH1 (normally
open contact) and CH2 (normally open/normally closed contact). The relays CH1 and CH2
can be activated by selecting the functions A-B-C-D and made to correspond with the
transmitter channels CHA, CHB, CHC, CHD by setting the jumpers "J1" situated on the
circuit board (see fig. 6).
Mini receivers
(fig. 7)
- The mini receiver (printed circuit CS1034) is housed in an indoor container and is fitted with
a terminal board with the following electrical connections:
12V ac/dc between the contacts 7-8.
24V ac/dc between the contacts 6-8.
The receiver cards are fitted with two relays, the outputs of which are marked CH1 (normally
open contact) and CH2 (normally open/normally closed contact). The relays CH1 and CH2
can be activated by selecting the functions A-B-C-D and made to correspond with the
transmitter channels CHA, CHB, CHC, CHD by setting the jumpers "J1" situated on the
circuit board (see fig. 7).

Functions
A. Memorising a channel
B. Cancelling a channel (via an associated radio transmitter)
C. Cancelling the entire user memory
Attention! Before memorising the transmitters for the first time remember to cancel the
entire memory content.
A- Memorising a channel (fig. 5)
1. Keep button "P1" 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 "P1" MEMO pressed down until led "L1" starts to flash again
4. Release the button and the LED continues 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
transmitter is activated (point 2) the led will stop flashing. The program will only work again
when button "P1" MEMO has been released.
• If the transmitter 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 activated 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.
B- Cancelling a channel (fig. 5)
1. Keep button "P2" DELETE pressed down and the led "L1" will start to flash rapidly
2. Press the channel on the transmitter which is to be cancelled
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 flash-
ing. The program will only work again when button "P2" 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. 5)
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 turn off meaning that the cancellation procedure has been carried out.
Note: It is only possible to switch from memorising mode to cancelling mode if you haven't
already entered the second part of the memorising procedure (point 4 onwards). Once this part
of the procedure has been reached the entire procedure will have to be completed. If you do
not wish to memorise a code which you have already transmitted wait for 15 seconds, the led
will switch off and the code won't be memorised. When the receiver's memory is almost full
the user search function can take up to 1 second to complete.
