LINK R4 is a device that integrates a transceiver operating at 868.3MHz with LoRaTM modulation and is capable of ensuring communications at very
long distance, high immunity to interference, high sensitivity and low power consumption.
The device, combined with the MARCONI LINK T4 decoder board or the MARCONI XTR-8LR-4ZN remote control, allows remote loads to be activated
and is ideal for very long distance (8km at sight) activation and control applications such as irrigation systems, alarms.
Below are the connections:
Functioning
The LINK R4 device, in order to limit the average consumption <1mA, autonomously manages an on/off cycle with appropriate duty-cycle. During the
period when it is receiving, it checks whether a valid transmission is in progress and if so, it remains in continuous reception for the time required for
decoding.
LINK R4 must always be paired with one or more LINK T4 or LINK T4 TELECOMMAND via the learning procedure described below. The
decoder can learn up to 48 encoders. When a valid packet transmitted by a learned encoder with a greater counter value (see encoder manual) is
decoded, within a window of 512, than the last one received, the corresponding
output CH1-4 is activated (relay closed). To select the operating mode of the outputs,
it’s necessary to set the dip switch as the table below:
MONO = the output is active for the duration of the pressing of the transmitter button
LATCH = the output changes state (active/disabled) to every pressing of the transmit-
ter button
MONO ½ = the output is active for ½ sec from the moment the transmitter button is pressed
To limit consumption it is possible to turn off the led POWER ON by switching the jumper J1 to the OFF position.
Self learning for transmitters
1. Press the button on the RF module and then release it.
2. The led on the RF module flashes for 10 sec: within this amount of time press any button of the transmitter. Once the learning is complete the led
lights steady for 1 sec.
3. The outputs are automatically associated to the buttons of the transmitters (ex. key 1 TX with output 1 RX, etc…)
Manual learning for transmitters
(possible only if all the outputs are set as impulsive i.e. SET 1 = SET 2 = HIGH)
1. Press the button on the RF module and then release it.
2. The led on the RF module flashes for 10 sec.
3. Press again within 10 sec. the button on the RF module. The led lights steadily.
4. Press again the button on the RF module to select the output 1 (the led flashes once), press again the button to select the output 2 (the led flashes
twice) and so on.
5. Once chosen the desired output, press the button of the remote to associate. The led flashes a number of times as the output number.
From this moment the selected output works as impulsive. Repeat the described procedure for further associations.
