1. GENERAL INFORMATION
The 230 Vac receiver integrates the functions of receiver and decoder of standard and 'rolling' codes. It is equipped with a memory capable of memorising
up to 200 different codes generated by transmitters of the MULTIPASS family, both standard and rolling code.
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

4. 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 (Fig.
1).
Programming
•
Power up the receiver correctly.
•
Press button P1: the red led lights up indicating that programming is in progress.
•
Carry out a transmission by 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.
5. CHANNEL ADDRESS
The M/R1E23O receiver's output relay can be activated by only one of the four channels available, after selecting the channel required by means of the
receiver's JP3 jumpers (Fig. 1), of a transmitter of the MULTIPASS family operating on a frequency of 433.920 MHz.
6. SELECTION OF TYPE OF OUTPUT RELAY
The M/R1E23O receiver's on-board relay may be of a monostable or bistable type depending on how the JP2 jumpers are configured (jumper closed:
monostable functioning; open: bistable).
