Method, see the description below for details) 1. Jog: Insert the black jumper on the receiver on the two pins A+L, which means all 8 channels are jog. <Function literal translation: Press and hold the remote control button to work, and release it to stop!> 2. Self-locking: Insert the black jumper on the receiver into the two pins B+L, which means all 8 channels are self-locking. <Function literal translation: the receiver is turned on and off by the same button on the remote control After finishing up, press the remote control buttons in turn, the first button is on, the second button is off, the third button is on, the fourth button is off, and so on!> 3. Interlock: Hang the three pins of the black jumper A, B, and C on the receiver, that is, all 8 channels are interlocked. <Function literal translation: Press the A button on the remote control to open the B button for off or the A button for Close the B button to open. If the remote control has multiple buttons, it will learn which button is on, and all other buttons are off!> 4. 1-4 channels jog. 5-8 channels self-locking: insert the black jumper on the receiver into the two pins of C+L. 5. 1-4 self-locking. 5-8 interlocking: insert the black jumper on the receiver into the two pins A+L and B+L. 6. 1-4 way jog. 5-5 way interlock: insert the black jumper on the receiver into the two pins B+L and C+L. 7. 1-2 way jog. 3-6 way self-locking. 7-8 way interlocking: insert the black jumper on the receiver on the two pins A+L and C+L. 8. 1-2 way jog. 3-6 way self-locking. 7-8 way interlocking: insert the black jumper on the receiver into the two pins A+L and B+L and C+L. can. 9. If the remote control is replaced with 16 keys, the 1-15 keys of the remote control each correspond to a relay, and the 16th key is the total key function by default. Add or delete the remote control instructions 1. Learning: Press the learning button on the receiving board once the green light is on and release it, then long press any key on the remote control to learn, the green light After the light flashes quickly, it indicates that the learning of all keys of the remote control is automatically completed, and the remote control can control operations. 2. The 2262, 2260, 1527 chip equivalent frequency fixed code learning code wireless remote control that can learn more than 20 different address codes; 3. Clear code: long press the key switch for more than 5 seconds, the green light will flash and then go out, indicating that the clear code is successful. 1 x Remote Control Relay Switch 1 x Remote Control Relay Switch Board
