RFSIA08 RFSOB08 is a wireless remote control switch with feedback function, 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.

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.
