RX-4MHCS --------------------------------------------------------------------------------------------------------------------------------------------------- User Manual RX-4MHCS 433.92 MHz OOK (AM) Receiver - 4 output channels Description The mono-stable and bi-stable mode and the open collector outputs make it ideal for telecontrol of appliances like gate door openers, burglar alarm systems and wherever its requested encoding of radio link. Furthermore its able to learn the code of HCS transmitters. Compatible with AUREL keyfobs: HCS-TX- 1/2/3 (OVO), TX1/2/3-HCS-433 (HCS), TX- 2/4/6 M-HCS, TX-12 CH.

Pin 9 shall be connected to the push button for programming the receiver, pin 14 shall be connected to the anode of LED to control that programming has been carried out (output current is internally limited to around 20 mA by a 180 ohm resistor). External antenna shall be connected, by utilizing for example a piece of wire 17 cm long and a surrounding widespread ground plane. Every output of RX-4MHCS is driven by a transistor in open collector configuration, able to bear max current of 100 mA. In stand-by mode transistor is cut off while when triggered is in saturation region. Output can be programmed to work in mono-stable or bi-stable mode, every one independent from the others. In mono-stable mode output is active for all the time the corresponding push button is pressed in the keyfob, releasing the button output switches off. In bi-stable mode output switches its state every time the corresponding push button is pressed in the keyfob (from active to inactive and vice versa). The two operative modes are independent each other, that means its possible to program some outputs as mono-stable and some others as bi-stable. If an inductive load is connected to the output (i.e. a relay) its necessary to prevent voltage transients by putting a diode in parallel to the inductive load. LED anode shall be connected towards the output of the module. In order to enable the receiver to activate its outputs its necessary to store in the RX-4MHCS the keyfobs codes. To carry out this operation its necessary to approach the keyfob to the receiver. By pressing a push button (it doesnt matter which one) of the keyfob during the auto-learning phase, the receiver RX-4MHCS recognises the button pressed and all other channels automatically. Only the keyfobs with HCS encoder shall be recognised by the receiver RX-4MHCS. Keyfobs not programmed or programmed with manufacturer code different from the one used by AUREL would not be recognised. Based on reasonable demand, Aurel is willing to program the receiver RX-4MHCS with specific manufacturer code indicated by the customer. Ground plane The circuit must be double layer. Ground plane must surround at the best the welding area of the receiver. For further info please refer to the user manuals of AURELs receivers.
