The code is changed for each encoding transmission throughthe use of an encoding algorithm which only the receiver is able to recognise andtherefore decide whether or not the code transmitted corresponds to the originalcode. The code is generated for each channel in the transmitter using the randomarbitrary method with 236 combinations. The generated code is memorised in thereceiver via radio. The receiver is able to memorise 32 different codes in the stand-ard version. During the transfer stage the codes are memorised in a non volatilememory module (93C46 for upto 32 codes) which can be moved to another re-ceiver without having to reprogram it. As this is a system based on dynamic codeseach code is processed individually by the receiver.Important:This is a device which uses a high security encoding system it follows there-fore that if you lose one or more transmitters you will have to reprogram thesystem codes. The transmitted code changes for each command (rolling code).Disturbance during the transmission will disactivate the relay, at this point the relaycan only be activated by first releasing and then pressing the transmitter channelbutton a second time.UseThe S435 radio control allows the remote activation of electrical and electronic ap-pliances with its best use in the following areas: automatic opening systems, alarmsystems, and in all systems which require remote control activation (without wires)using secret codes, in compliance with the safety standards governing the installa-tion of appliances.Transmitter versionsS435 TX2 Miniaturised transmitters 2 ButtonsS435 TX4 Miniaturised transmitters 4 ButtonsS435 TX12 Miniaturised transmitters with switch (12 channels) 4 ButtonsReceiver versionsS435 RXG1CH Slot-in receiver card (up to 32 codes) 1 ChannelReceiver antenna installationNB. Minimum and maximum range of the radio controls. ‘Range’ is intended tomean the working distance, measured in free space, between the receiver andthe transmitter with the antenna installed. The range is therefore closely linkedto the technical characteristics of the system (power and sensibility) and variesaccording to the characteristics of the site in which the system is located.It therefore follows that to obtain the best results from the radio control theinstallation sites for the receiver and the antenna should be carefully chosen.Note: It is not possible to install 2 receivers at a distance of less than 1.5 mt.from each other.AntennaThe installation of the antenna is fundamental, connected to the receiver it representsthe reception point for the radio control.When installing the antenna the following points should be observed:The receiver is supplied with its own antenna which consists of a piece of rigid wire170 mm in length. In alternative it is possible to connect an ANS400 tuned antennausing a coaxial cable RG58 (impedance 50 Ω) with a maximum length of 15 m.The antenna should be positioned out of doors in the highest possible point, visibleand away from metal structures.ReceiversThe receiver consists of a card inserted directly into an appliance which is designedto receive it.NB. It is good practise to position the receiver away from computer systems, alarmsystems and other possible sources of disturbance. (A bad choice of positioningcould compromise the correct performance of the receiver).Generating the user code in the transmitters (fig. 1-6)1) Open the access door (fig.1)2) For the version equipped with a channel block selection switch choose the desiredblock of channels by moving the switch "Y1" (fig.2)3) Press the button "J1"4) While keeping button "J1" pressed down press the button "CH" corresponding tothe required channel which is to be memorised (Led "L1" will start to flash) (fig.4).5) Release the channel button "CH" and the led will carry on flashing (fig.5).6) Release the button "J1", the led will turn off and the transmitter will memorise thelast code which was transmitted (fig.6).7) Repeat points 3-4-5-6 for any successive channels8) To memorise another block of channels move the switch "Y1" to the requiredposition and repeat the operations 3-4-5-6.If a code is not generated it could be due to the fact that the memory is empty andit is therefore impossible to transfer the code to the receiver.DIGITAL RADIO CONTROLS WITH DYNAMIC CODES S435Memorising the user code in the receiver (fig. 9)1) Keep button "P1" pressed down and the led "LD1" will start to flash2) Transmit the channel which is to be memorised, the led will flash rapidly and thechannel will be memorised. Only one code can be inserted at a time. To insert suc-cessive codes repeat steps 1 and 2.If the code is not memorised it could be due to the following:- The memory is full (32 codes already memorised) and the led remains lit. If this isthe case you can only insert a new code after you have first cancelled an existing oneor after wiping the entire memory (see memory cancelling procedure);- The code may already exist in memory;- You have not generated a channel code in the transmitter.Memory cancelling procedureTo cancel a code proceed as follows:1) Keep the button "P2" pressed down and the led "LD1" will flash slowly.2) Transmit the channel which is to be cancelled for at least 3 seconds until the ledstarts to flash quickly then repeat points 1 and 2 for any successive channels.To wipe all the code from memory:3) Keep buttons "P1" and "P2" pressed down simultaneously for at least 5 secondsMemory moduleThis is extractable, furnished with a non volatile EEPROM type memory and containsthe system code. The programmed code is maintained in this module even in theabsence of power.Channel functions for the S435 radio controlsChannel "A" of the transmitter must always correspond to channel "A" of the receiverand so forth for all four of the available channels . Remember that the receiver canonly respond to one signal at a time, it therefore follows that several channels cannotbe activated simultaneously.ReceiverUsing the dip switch "D1" select the desired channel by moving only one of the switchesto the "ON" position. The receiver can decode up to 12 different channels in blocks of3 (A,B,C,D - E,F,G,H - I,L,M,N.) by inserting the jumper "J1" in the right position.TECHNICAL SPECIFICATIONSRECEIVER- reception frequency ............................................... 433,92 Mhz- local oscillation frequency ................................... 433,42 Mhz- local oscillation emission ....................................... <57dBm (<2nW)- intermediate frequency IF ...................................... 500 KHz- antenna impedance in input .................................. 50 Ω- sensitivity (finely tuned signal) ............................... 1 μ V- power supply ........................................................ 24 V dc- Open collector output with maximum load ........... 50 mA- maximum power consumption ............................. 20 mA- operating temperature range ................................. -20°…+60°CTRASMITTERS- carrier frequency .................................................... 433.92 Mhz- carrier frequency tolerance .................................... ±75 Khz- band width ............................................................. >25 Khz- apparent radiated power ....................................... -20…-16dBm (10-20μW)- apparent power harmonic products ...................... <-54 dBm (<4nW)- modulation .............................................................
