information on the receiver side. The 3 steps depends on the supply voltage. For +U = 3.3 V the steps are as
follows:
Voltage > 1.0 V :
Voltage 0.9 to 1.0 V
Voltage 0.5 to 0.9 V
Voltage < 0.5 V :
13 n/c
14 Output to control a LED (low active) as a function of the transmitters supply voltage
transmitters supply voltage >2.3V:
transmitters supply voltage 2.0 to 2.3V:
transmitters supply voltage <2.0:
15 Antenna
Connection for an antenna ( 173mm wire) or 50Ohm-coaxial cable.
16 Antenna GND Connection for the shield of a 50Ohm-coaxial-cable
4 Operation
For the location of the receiver module, select a place which is not shielded by conducting objects and position the antenna in such a
way that it is not subject to interference from the rest of the circuit and is parallel to the transmitter antenna.
Pay attention to the correct polarity when performing the connections and make sure the technical data are kept within
specifications.
Caution: If the voltage supply exceeds the specified voltage, the electronic components may be destroyed, for example, when
using unregulated voltage sources.
Antenna: The most simple antenna is a wire with a length of 173mm . But you may connect also a 50 Ohm coaxial cable if an antenna
has to be mounted away from the module.
Supply: Connect the positive supply voltage to +U (Pin10) and the negative voltage to GND (Pin11).
Caution: Absolute maximum of supply voltage is 3.6 V.
Higher voltages will damage the module !
Learning transmitters code: Connect shortly the Learn-/Erase input (pin 2) to GND. The LED connected at pin 3 is switched on. Now
activate the desired transmitter until the LED flashes (the first transmitter is programmed). Please repeat the steps for all transmitters to
be used with this receiver.
The Learn mode is stopped automatically after 30 s.
Erasing all transmitter codes: Connect the Learn-/Erase input for at least 5s to GND until the LED starts flashing.
Please refer to the circuit example in the annex.
Input to fix the working frequency
open or +U: Frequency 1 (433.62 MHz)
GND: Frequency 2 (434.22 MHz)
same as output D4 (Pin4)
same as output D4 (Pin4)
positive voltage supply between 2.0 and 3.6 V DC
Ground, 0V DC
the status of a supplied voltage is sent back to the transmitter and may be used for battery
supply is ok – the transmitters LED remains off
:
medium supply – the transmitters LED flashes slowly
:
supply low – transmitters LED flashes quickly
not allowed; for service purposes only
do not connect
LED remains off
LED flashes
LED is on
