RFSIA08 RFSOB08 is an 8-channel bidirectional remote control switch with feedback based on LORA, no configuration required, as long as the transceiver ''Frequency and ID'' settings are consistent, it can be controlled. With feedback function, the LED indicator on the transmitter will indicate the switch status of the receiver.

Transceiver feature:
Three frequency versions: 433M 868M 915M
Based on Low Power LoRa Transceiver LLCC68
Transmitting power 22dBm
Receiving sensitivity -123dBm
Transmission distance up to 2000 meters in open area
Bidirectional Remote Control Switch with Feedback Indication
All Parameter setting by dip switch(Frequency/ID/Mode)
Four working modes:Non-locking Self-locking Inter-locking Delay 5 seconds

How to use RFSIA08 RFSOB08:
1 Install antennas on the transceivers
2 Use wires to lead out the COM port of the transmitter (RFSIA08) (can be ignored)
3 Connect the DC 12V power supply to the transceivers
4 Check whether the status of the transceiver's DIP switches is consistent (it is recommended to turn all OFF for the first use)
5 Short the COM and IN1-8 of the transceiver to control the 8 relays of the receiver.

Note:
1 The transmitter and transceiver must be used together and cannot be used separately
2 The frequency and ID of the transmitter and transceiver must be the same to communicate
3 The transmitter and transceiver must use the same frequency, otherwise they cannot communicate.
