MINI RF4 V2: How To Set Up & Use

Introduction

This article provides a detailed step-by-step guide to setting up your Rockville Mini RF4 V2 light(s). This incredibly compact, but powerful light is great for a wide array of events and color washing applications; providing customizable lighting effects that can be controlled wirelessly from anywhere in the room using an RF remote, DMX controller or WiFi-enabled app. This guide covers physical setup, control modes and wireless configurations for various lighting effects. The setup processes covered here are designed to be simple, even for users with no technical experience. For our lighting pros and those looking for more advanced control, a Rockville Wireless DMX Controller(or DMX Transmitter) can be used for full (512 channel) DMX control.

Requirements:
✅Rockville Mini RF4 V2 (available in black or white)
✅Included RF Remote (optional; for remote control)
✅Rockville Wireless DMX Controller (optional; for DMX control)
✅Rockville Par-Control App on Mobile Device (optional; for App control)
✅Rockville LC70 or Similar Lighting Clamp (optional; for mounting)

Setup Guide

A.) Mounting & Positioning

Positioning the Light with the Bracket:
The built-in bracket allows you to adjust the light’s angle for wall washing, up-lighting or stage lighting.

• Adjusting the Bracket for Positioning in Any Location
  1. Loosen the side knobs to adjust the angle.
  2. Tilt the light to the desired position.
  3. Tighten the knobs to lock it in place.
• Wall Washing Setup
  • Use the bracket to angle the light for wall washing.
  • Position the light a few inches from the wall for even illumination.
  • For a more intense effect, position the light closer to the wall.
• Lighting a DJ Facade
  • Position the Mini RF4 V2 at the base of a DJ facade and angle it upwards.
  • For full and even illumination of your facade, use one light per panel.

Positioning the Light with the Feet:
The Mini RF4 V2 's built-in feet allow for stable placement on the floor, against a wall or inside a totem stand.

• Wall Washing / Up-Lighting
  • Place the light directly against a wall or DJ facade with the feet down for a strong upward beam.
  • Works well for accent lighting on walls, drapes or event backdrops.
• Totem Stand Placement
  The feet also allow the Mini RF4 V2 to fit securely inside a totem stand to create a glowing effect inside.
  1. Lift the scrim of your totem stand.
  2. Place the Mini RF4 V2 inside, facing upwards.
  3. Set your desired color or mode on the light.
  4. Lower the scrim back down.

Mounting to a Truss (or Speaker Stand Pole) Using the Bracket and Clamp:
If you want to mount the Mini RF4 V2 to a lighting truss, beam or speaker stand pole you’ll need a lighting clamp like the Rockville LC70.

• Attaching a Lighting Clamp
  1. Take the clamp and remove the bolt.
  2. Locate the mounting hole on the bracket and insert the bolt through it.
  3. Align the screw hole on the outside of the clamp with the threads from the bolt.
  4. Secure the clamp onto the bracket by tightening the bolt.
• Placing & Adjusting the Light on a Truss, Beam or Speaker Stand Pole
  1. Loosen the clamps butterfly screw until wider than truss / beam/ pole diameter.
  2. Position the clamp on your truss, beam or speaker stand pole.
  3. Tighten the butterfly screw to lock the light in place.
  4. Adjust the angle of the light to direct the beam where needed.

  3. Use the remote to control each group independently by switching RF groups (e.g., red for RF1, green for RF2).
• Test the Setup:
  1. Power on the light(s) and test each mode (e.g., color, jump, fade, sound) using the remote.
  2. Verify battery life and charge if needed.
  3. Adjust angles or reposition for desired lighting effects (e.g., wall washing, truss lighting).
  4. Ensure each light responds correctly to remote functions and sound to ensure optimal effect.

Troubleshooting & FAQs

Light does not turn on:
✅Confirm that light has not gotten wet.
✅Check the battery life indicator; charge if red or orange.
✅Ensure the power button is able to be pressed in fully (not jammed / debree wedged).

Remote not controlling the light: 
✅Confirm the light is in RF mode and set to slave mode.
✅Verify the remote and light are on the same RF group (e.g., RF1 with red flash).
✅Check the remote’s battery and replace it if needed.

How many Slave lights can I control with one Master?
✅Up to 25 Slave lights can be wirelessly linked to a single Master.

Can I sync my other Rockville lights with my Mini RF4 V2s in Master/Slave Mode
✅Normally Master/Slave Mode only works with lights of the same exact model. However the Rockville Mini IR-series can be linked with the Mini RF-Series because they have the same DMX response. 
✅No lights of other models or brands can be linked using Master/Slave. You may want to consider using a DMX controller to sync any lights with DMX capabilities.

Slave lights not following master: 
✅Verify all lights are on the same wireless ID (e.g., red).
✅Ensure master mode on the master light set to on, and on slave lights is set to off.
✅Check that slave lights are in DMX address/slave mode with a flashing wireless ID icon.

How many lights can I connect with a DMX Controller?
✅25 lights can be wirelessly linked directly to a Rockville Wireless DMX Controller or Transmitter.
✅25 more lights can be linked to another Rockville Wireless DMX Transmitter connected to same DMX output.

DMX controller not working: 
✅Ensure the controller (or transmitter) and light are set to the same Wireless ID (e.g., red).
✅Confirm light(s) set to the correct DMX Address and Channel Mode.
✅Check that the correct DMX scanner / fixture (e.g., Scanner 1) is enabled on the controller.

Sound mode not responding:
✅Increase sensitivity setting; Press the Enter button once in sound mode, then use the Up button to set to 9.
✅Ensure ambient sound is loud enough or test with louder audio.

App not connecting: 
✅Confirm the light is in app group mode and note the WiFi code.
✅Connect your phone to the light’s WiFi network using the code.
✅Ensure the Rockville Par-Control App is installed and updated.
