This video introduces the wiring relationship between the dimming module and the smart hotel wall panel.
The wall panel is used by the guest, but the actual dimming output is handled by the dimming module or controller.
The panel communicates with the guest room control system through RS485.
The dimming module receives commands and adjusts the brightness of the connected lighting circuit.
Each output channel must correspond to one lighting circuit or one dimmable driver group.
The strong-current wiring and the communication wiring should be separated clearly.
The RS485 bus connects the wall panel, RCU, gateway controller, or dimming module according to the project design.
A and B communication wires must be connected consistently on every device.
If A and B are reversed, the device may not communicate correctly.
The load output from the dimming module connects to the dimmable power supply or dimmable lamp.
The wiring table should show which channel controls each light.
The wall panel button label should also match the actual light name.
Engineering Notes
| Item | Recommendation |
|---|---|
| Communication | Use RS485 bus communication for stable hotel guest room control. |
| Control Logic | Map each wall panel button to the correct circuit, dimming channel, and scene mode. |
| Project Stage | Confirm drawings, wiring, and device selection before site installation. |
FAQ
Why use RS485 for hotel guest rooms?
RS485 is stable, wired, and suitable for multi-room engineering projects.
Can the panel labels be customized?
Yes. Labels such as Reading, Sleep, Master Off, Curtain, Bathroom, and scene names can be customized.
Does this replace the original video audio?
No. The final video keeps the original audio and adds English subtitles only.
