MINI RF4 V2: How To Set Up Master/Slave Mode

Introduction

This article will walk you through how to use the Master/Slave function on your Rockville Mini RF4 V2 lights. This feature allows one light to control the rest without using a DMX controller, which is ideal for quick setups or synchronized effects. No technical experience is required, and these steps are easy to follow. You’ll just need two or more Mini RF4 V2 lights powered on and within wireless range.

⚠️Please note: This does not allow for remote control, only manual control using Master Light. Remote control setup instructions for multiple Mini RF4 V2 lights can be found in another article, How To Set Up RF Remote Groups.
