Wiring Diagram

7.1 Connection Between Zone Receiver to LEDs

The WiFi-104 defaults to zone NO.1. Slave control defaults to zone NO.1 if no lights are connected. All zones can be used for the same LED types (e.g., single color dimming) or different types (Dimming, CT, RGB, RGBW) per zone.

Connections:

• Zone 1 (DIM): Connects to a single color LED strip.
• Zone 2 (CT): Connects to a nature white/warm white strip.
• Zone 3 (CCT): Connects to a nature white + warm white + cold white strip.
• Zone 4 (RGB): Connects to an RGB strip.
• Zone 5 (RGBW): Connects to an RGBW strip.

The diagrams illustrate the connections between the R4-5A/R4-CC receivers and the respective LED strips, showing power input (5-24Vdc) and output terminals for each color channel (R, G, B, W).

7.2 Direct Connection of Using WiFi-104 as Router

In this setup, the WiFi-104 acts as the central router. It connects to multiple zone receivers (up to 12 zones) directly, forming a star topology. A mobile phone connects to the WiFi-104 to control the system.

7.3 Extra Router Connection

This setup involves using a separate wireless router. The WiFi-104 controller connects to this wireless router, and the router then manages connections to multiple zone receivers (up to 12 zones per controller). This allows for extended range and network integration. Unlimited zone receivers can be installed within the effective range of the system.
