CAUTION FOR THE USER

Any change or modification of the product is forbidden if not expressly

approved by the manufacturer

1. GENERAL INFORMATION

These receivers integrate the functions of standard Multipass and Multipass Roll code receivers and decoders.

They feature a storage capacity of up to 200 different codes generated by transmitters of the Multipass and

Multipass Roll family at 433.920 MHz (M/RA1E - M/RA2E).

2. ROLLING CODING

This type of coding affords extra security as it prevents the risk of code violation by interception or re-

transmission. It is based on the transmission of a batch of bits consisting of a fixed part (which is different for each

transmitter), of channel bits associated with the switch of the activated transmitter, and of a part which changes in

a pseudo-random manner (rolling code) in accordance with a proprietary Prastel algorithm. The configuration of

these latter bits changes unpredictably from one transmission to the following. The receiver memorises by self-

learning the fixed part of the code associated with each transmitter plus the relevant rolling code, updating the

latter upon each transmission. Transmitter recognition occurs only if the transmitted rolling code corresponds to

the 255 configurations subsequent to the last recognised transmission. Realignment and recognition of a

previously memorised transmitter which has overrun the permissible interval (an event which may occur for

example following on an excess of unrecognised transmissions or upon battery replacement) can however be

made by pressing and releasing the transmitter learning button. This procedure permits the system to check for

code correctness, while safeguarding the advantages afforded by the rolling code.

4. VOLTAGE SELECTION

Both the M/RA2E-M/RA1E receivers can operate at 24V and 12V ac/dc.

5. CODE PROGRAMMING AND DELETION

Entry and storage of a new code and deletion of the full code list can be made by acting on key P1, while deletion

of single user codes can be made using the GT/BASER portable terminal.

How to Program

• Power the receiver as specified.

• Press P1. The red LED lights up indicating that programming is in progress.

• Press any of the transmitter’s keys to make a transmission.

• The code will now be entered in the memory. While loading is in progress, LED will flash. Upon code being

stored, the LED stops flashing and becomes fixed. A new code can now be entered.

• Load the codes of all the transmitters by making a transmission with each of them.

In any case, the system will automatically exit from programming mode upon 10 seconds having elapsed since last loading. Codes remain stored even if receiver is powered off. Attention: Make a transmission within 10 seconds after pressing P1 as system will automatically exit from programming mode after this time has elapsed if no transmission has been made.
