MR series Receivers
1.
GENERAL DESCRIPTION
The MR receiver integrates the functions of receiver and decoder of standard and 'rolling' codes. It's memory, is capable of memorising
from up to 1000 different codes generated by transmitters of the MPS and XP families. It's possible to link whatever transmitter button to
whatever relay mounted on the receiver.
Intended use of the equipment: radio receiver in garage-door systems.
2.
ROLLING CODIFICATION
The purpose of this codification is to prevent the possibility of violation of the code by capture and retransmission. Rolling code involves
the transmission of a batch of bits consisting of a constant part, different for each transmitter, the channel bits related to the transmitter
switch activated plus a part that varies with each transmission in a pseudo-random manner (rolling code) in accordance with a proprietary
Prastel algorithm. Configuration of these bits varies unpredictably between two consecutive transmissions. The receiver, by self-learning,
memorises the constant part of the code of each transmitter plus the appropriate rolling code and updates the latter at each transmission.
The transmitter is recognised only if it sends a rolling code corresponding to the 255 configurations subsequent to the last recognised
transmission. Nevertheless it allows realignment and recognition of a previously memorised transmitter that has overrun the permitted
interval (e.g. due to an excess of unrecognised transmissions or on replacement of power supply batteries) by pressing and releasing the
transmitter learning button; in this way the correctness of the code is analysed, maintaining the advantages of the variable codification.
RPA Function (Transmitter remote self-learning command).

CODE PROGRAMMING AND CANCELLATION
Operations of inserting a new code into the memory and cancelling the whole list of codes can be carried out using the same button
"ENTER RADIO" on the receiver.
"FREE" programming mode
•
Power up the receiver correctly.
•
Press button "ENTER RADIO": all red leds lights up for 2 sec.
Then only the first led remains on to indicate that first relay is
selected.
•
Select the relay you wish to link to the transmitter pressing
"SET" button repeatedly.
•
Carry out a transmission pressing a transmitter button. Each
button identifies a channel and corresponds to a different
transmission.
•
If led flashes slowly, insertion is running. When done
the led returns in non-flashing state.
•
If a led begins flashing quickly, the channel has already
been programmed and is associated to the flashing led.
Carry out another transmission with the same button to
update the programmation to selected relay.
•
If all red leds flash at the same time, memory is full.
Insertion is not done.
•
Repeat the procedure for all transmitter buttons (channels)
you want to program on the receiver, each time selcting the
desired associated relay.
•
Memorise all the transmitters by carrying out a transmission
with each one.
•
At the end of the operation press button "ENTER RADIO"
again to exit from the procedure. The led goes out. Exit from
the programme comes about automatically in any case 10
seconds after the last memorisation.
•
The codes remain in the memory even if the receiver's power
supply is cut.
