XTR-8LR-DEC --------------------------------------------------------------------------------------------------------------------------------------------------------------------- User manual TM XTR-8LR-DEC is a transceiver based on LoRa modulation able to guarantee ultra long range communication, high interference immunity , very high sensitivity and very low current consumption. Compared to standard modulation techniques, LoRa improves up to 20 dB the receiver sensitivity, allowing long distances by using low power transmission and very low consumption, inexpensive power supply circuits and reduced dimensions. The receiver XTR-8LR-DEC, to be paired with Aurel transmitter XTR-8LR-DEC or with Aurel keyfob XTR-8LR-4ZN, allows to activate remote loads. Its ideal when it has to activate and control loads at very long distance like, for example, in irrigation or alarms systems applications. The module has 4 open collector outputs and two inputs for setting monostable or bistable output mode. The device manages a cyclic wake up from power down mode and subsequent reception to obtain an average current consumption < 1mA useful for battery power supply application. XTR-8LR-ENC sends an acknowledgment packet (ACK) to the paired transmitter (X TR-8LR-ENC or XTR- 8LR-4ZN) with a secure encrypted RF communication.
