RX-4MHCS
433.92 MHz OOK (AM) Receiver - 4 ou pu channels
Descrip ion
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 where er it’s requested
encoding of
radio link. Furthermore it’s able to learn the code of
HCS transmitters.
Compa ible wi h AUREL keyfobs: HCS-TX-
1/2/3 (OVO), TX1/2/3-HCS-433 (HCS), TX-
2/4/6 M-HCS, TX-12 CH.

How o ge s ar ed
The oltage supply to the module (pin 15) shall be 5Vdc. Pin 9 shall be connected to the push button for
programming the recei er, 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.
E ery output of RX-4MHCS is dri en 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, e ery one independent from the others.
In mono-stable mode output is acti e 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 e ery time the corresponding push button is pressed in the
keyfob (from acti e to inacti e and ice ersa). The two operati e modes are independent each other, that
means it’s possible to program some outputs as mono-stable and some others as bi-stable.
If an inducti e load is connected to the output (i.e. a relay) it’s necessary to pre ent oltage transients by
putting a diode in parallel to the inducti e load. LED anode shall be connected towards the output of the
module.
In order to enable the recei er to acti ate its outputs it’s necessary to store in the RX-4MHCS the keyfobs
codes. To carry out this operation it’s necessary to approach the keyfob to the recei er. By pressing a push
button (it doesn’t matter which one) of the keyfob during the auto-learning phase, the recei er RX-4MHCS
recognises the button pressed and all other channels automatically.
Only the keyfobs with HCS encoder shall be recognised by the recei er 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 recei er 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 recei er.
For further info please refer to the user manuals of AUREL’s recei ers.

Programming
How to erase the memory
In order to reset the RX-4MHCS, press the push button connected to pin 9 and release it when LED starts
blinking. Now press again the push button and hold it pressed for around 5 seconds until it switches off
again. As you release the push button the LED blinks 5 times indicating that memory has been erased.
After carrying out the reset, no HCS encoded keyfob shall be recognised and all outputs shall be set up in
mono-stable mode.
Auto-learning procedure
By pressing and soon releasing the programming push button the auto-learning procedure is initiated. LED
blinks quickly for 10 seconds: for this time long, e ery time a push button of a keyfob, located near the RX-
4MHCS, is pressed, such keyfob would be learnt. Programming of RX-4MHCS is confirmed by LED with
steady red light, afterwards it switches off.
When programmed all push buttons of the keyfob are learnt and each of them acti ate the corresponding
output. Outputs will be mono-stable.
It’s possible to repeat this procedure to allow the recei er RX-4MHCS to learn up to 10 keyfobs.
Bi-stable mode programming
To get the bistable output, press and release the programming button, connected to the pin 9.
The LED starts blinking quickly for 10 seconds. Press the programming button again during this time. The
LED changes from blinking to steady light. In the next 10 seconds, when the reference LED is steady, it is
possible to press the button related to the channel you want to change in bistable mode. The recei er
indicates the correct programming of the bistable mode with three LED flashes.
To return the monostable operating mode, repeat the abo e procedure; in this case, correct programming is
indicated by two LED flashes.
Switching the output mode from bistable to monostable can only be done after the recei er has learnt the
transmitter.
