Detailed Answer
Industrial remote controls prevent cross-interference mainly through three technologies: pairing (binding a transmitter and receiver with a unique code), frequency-hopping spread spectrum (FHSS, with different units using different hopping sequences), and independent channels (433/470MHz multi-channel division). LDER uses one-key pairing + FHSS, and XINGJIA supports adaptive frequency hopping, so even dozens of units working on the same site will not interfere with each other. Code conflicts can cause false actuation, so in multi-unit factories every set of equipment must be paired independently.
| Pairing | Unique binding |
| FHSS | Hopping sequence isolation |
| Channels | Multi-channel division |
Note:When multiple units share a site, each set must be paired independently.
