MRA2E – MRA1EENGLISHMRAE_V0Member of: AssociatedCAUTION FOR THE USERAny change or modification of the product is forbidden if not expresslyapproved by the manufacturer1. GENERAL INFORMATIONThese 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 andMultipass Roll family at 433.920 MHz (M/RA1E - M/RA2E).2. ROLLING CODINGThis 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 eachtransmitter), of channel bits associated with the switch of the activated transmitter, and of a part which changes ina pseudo-random manner (rolling code) in accordance with a proprietary Prastel algorithm. The configuration ofthese 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 thelatter upon each transmission. Transmitter recognition occurs only if the transmitted rolling code corresponds tothe 255 configurations subsequent to the last recognised transmission. Realignment and recognition of apreviously memorised transmitter which has overrun the permissible interval (an event which may occur forexample following on an excess of unrecognised transmissions or upon battery replacement) can however bemade by pressing and releasing the transmitter learning button. This procedure permits the system to check forcode correctness, while safeguarding the advantages afforded by the rolling code.3.

VOLTAGE SELECTIONBoth the M/RA2E-M/RA1E receivers can operate at 24V and 12V ac/dc.5. CODE PROGRAMMING AND DELETIONEntry and storage of a new code and deletion of the full code list can be made by acting on key P1, while deletionof 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 beingstored, 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.
MRA2E – MRA1EENGLISHMRAE_V0Member of: Associated• Upon this operation being completed, press P1 again to exit from programming mode. The LED will go off. Inany case, the system will automatically exit from programming mode upon 10 seconds having elapsed sincelast 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 fromprogramming mode after this time has elapsed if no transmission has been made. To re-access programming mode, press P1 again. Deletion of all codes • Press and hold down key P1 until the red LED starts flashing.• Press P1 again within 6 seconds to confirm deletion. Confirmation is signalled by the LED flashing morerapidly. 6. CHANNEL SELECTION AND RELAY OPERATING MODE Set output as desired by means of jumper A (jumper A closed for monostable relay operation and jumper A openfor bistable relay operation). Note: Relay operating mode selection is not contemplated on the M/RA2Ereceiver. 7. ANTENNA CONNECTIONThe receivers may be connected to external antennas of corresponding frequencies by means of the appropriateF-type female connectors.The M/RA1E and M/RA2E receivers can instead be connected to ANT/433SD type antennas, to the wireantenna provided or the like.M/RA1E M/RA2EARelay operating mode selectionBF-type female antenna connectorCMicro-match for memory controlDChannel selection jumperEPlug connector inputACBFIG.1EOutput A 4 3 2 1 (Channel)DBAOutput BOutput A 4 3 2 1 (Channels) FIG.2ECD
