The functionality of the device RCQ3-868 are the following :

- Wireless Switch ( distance >1000meters in open field)

The 4 Output of MODULE A (RL1,RL2,RL3,RL4) corrisponding to the 4 Input of MODULE B (K1,K2,K3,K4), the 4 Output of the MODULE B corrisponding to the 4 Input of the MODULE A. The system can be work in :

- One to One operation (see the picture below) - One to many (1 device transmit and more devices receive)

- Wireless Actuator ( distance >1000meters in open field)
Wireless actuator for home automation, it’s possible use 1 unit as Transmitter (controllable via Rs232 serial interface) and by one or more RX units with the possibility to switch 4 channels in bistable or monostable mode for every RX units.The unit denominated used ad Transmitter can be controlled by a normal PC by a Raspberry device or by an Arduino microcontroller. It is possible to have a "point to point" configuration (No.1 TX unit - No.1 RX unit) or a "point-multipoint" configuration (No. 1 TX unit more RX Unit). It is also possible to monitor the status of the 4 inputs of the remote units S1, S2, S3, S4.

- Wireless Controller ( distance >1000meters in open field)
It’s an 4 channels wireless controller module with pairing function, it’s possible to control and verify the logic state (open or close) of the Remote Module.
