1. Equipment installation
(1) Equipment installation and 304 stainless steel rainproof power supply box, with priority given to installing antennas before power on;
(2) Connect the PWR quick connector and press the ON/OFF power button;
(3) The STA green light flashes rapidly and then slowly, indicating normal operation, while the red light flashes indicating interruption of the wireless relay link;
(4) Wireless repeater, wireless rope switch, and wireless host are paired and installed. The pairing program is completed by default before leaving the factory. The device ID is attached to the surface of the product and installed according to the corresponding point table;
2. Matching point table
| Wireless rope switch | Wireless Repeater | Wireless Host | |

| 2 | ID17～ID48 | ID2/ID3 | |
| 3 | ID49～ID76 | ID4/ID5 | |
| 4 | ID77～ID98 | ID6/ID7 | |
| 5 | ID77～ID98 | ID8 |

Power supply instructions
(1) The repeater is powered by two methods: on-site power supply and solar cell power supply
(2) The on-site power supply is the main one, and it will automatically switch to solar power supply after the on-site power outage
(3) Even without sunlight, the battery can provide 200 hours of electricity
(4) The power switching module has been connected and installed before leaving the factory
(5) The air switch is the main switch
(6) The relay light is on for on-site power supply, and off for solar power supply
(7) At that time, when solar energy was used for power supply, the equipment reported the current power supply method and battery level situation
(8) The intelligent gateway is connected to the upper computer through a network cable for data transmission, and the transmission protocol is MODBUS TCP.
