1.
GENERAL INFORMATION
The MRBE receiver integrates the functions of receiver and decoder of standard and 'rolling' codes. Its memories, both traditional and rolling
code type, are capable of memorising from up to 1000 different codes generated by transmitters of the MULTIPASS and MULTIPASS Roll
families.
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 P1 on the
receiver.
Programming
•
Power up the receiver correctly.
•
Press button P1: the red led lights up indicating that programming is in progress.
•
Carry out a transmission pressing any transmitter button.
•
The code is inserted into the memory. The led flashes during insertion. At the end the led returns to the non-flashing state, indicating that
a new code may be inserted.
•
Memorise all the transmitters by carrying out a transmission with each one.
•
At the end of the operation press button P1 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.
Total cancellation of codes
•
Hold button P1 pressed until the red led starts flashing.
•
Press button P1 again within 6 seconds to confirm cancellation. Confirmation is indicated by the led flashing with greater frequency.

CHANNEL ADDRESS
Insert the desired channel module series SK/3 in the connector of the desired channel.
E.g. SK/3 = monostable on connector J5 channel 1; SK/3T = timed on connector J4 channel 2; SK/3RB = bistable on connector J3 channel 3
and SK/3 monostable on connector J2 channel 1.
7.
SELECTION OF TYPE OF OUTPUT RELAY
The MRBE receiver's on-board relay may be of a monostable or bistable type depending on the pre-selected module. E.g. SK/3 = monostable;
SK/3T = timed; SK/3B = bistable.
