RC4 S3 Dimmer Mode Selection (firmware v71 and higher)

These instructions apply to all RC4 Series 3 Harmonized Design devices with firmware versions 4.071 / 2-71-x-x or later.  Applicable devices include:

  • RC4Magic Series 3 and RC4Magic-900 DMX2dim, DMX4dim, DMX4dim-500
  • LumenDim4, LumenDimM4
  • W-DIM4, W-DIMm3

Mode selection is a Func+Button feature, and the selected mode is confirmed using Patterns of Two LEDs.  These are described in detail in http://rc4.info/s3-ui-nomenclature/.

  • Func + SetA Restores Factory Defaults.  This clears ALL device parameters including mode, which is restored to Simple DMX Mode.
  • Func + SetB increments to the next mode in the list of modes below.  Incrementing from the last mode returns to the first mode.

Device Mode Indication

When changing mode, the DimA and DimB indicators provide feedback to the user.  This also causes loads connected to these outputs to blink.  Only two indicators are used so that the same indication method can be used on all devices with 2 or more dimmers.  There are 8 modes, indicated by different patterns of DimA/DimB blinks:

DimA
DimB

This is the default mode.  It is the most basic, used for the majority of wireless dimming applications.  Each dimmer is assigned a DMX channel, curve, PWM frequency, and RC4 Digital Persistence time. (RDM control supports individual frequency and persistence settings for each dimmer; RC4MagicPC supports one frequency and persistence setting for all dimmers set to an ISL dimming curve.)

When using RC4 ColorMatchTM to correct and match the color palette of different RGB and RGBW light sources, the initial matching process should be done in this mode, starting with the ColorMatch mode disabled.  ColorMatchTM offsets are disabled (not applied) when the COP blink is single-blip, and enabled (applied and visible) when the COP blink is double-blip.

Cross-Fade -> DimA/B, DimC/D [BAA][Mode 1]

DimA
DimB

The RC4 Cross-Fade Engine uses two DMX control channels for Color Temperature and Level, and translates this information to dimmer levels for warm white and cool white (or any other two sources).  The mix between the two sources sets a proportional color temperature, or mix.   The proportions are maintained throughout the range of levels, ensuring accurate color temperature at any brightness.

Connect warm white source to DimA, and cool white source to DimB.

If using a 4-channel dimmer, a second Cross-Fade pair is also available:  Connect warm white source to DimC, and cool white source to DimD.

Flkr -> DimA/B/C, DMX -> DimD [ABA][Mode 2]

DimA
DimB

The RC4 Wireless Flkr Engine drives DimA, B, and C.

DimD is not controlled by the Flkr engine. Instead, it is directly controlled by the DMX channel assigned for DimD.  Thus, this mode provides a 3-color Flkr effect, and one general purpose dimmer.

Flkr -> DimA/B/C/D [BBA][Mode 3]

DimA
DimB

All 4 dimmers are controlled by the RC4 Wireless Flkr Engine.  This is the most commonly used Flkr Engine mode.

HSL -> DimA/B/C, DMX -> DimD [AAB][Mode 4]

DimA
DimB

The HSL color controller uses three DMX control channels for Hue, Saturation, and Level, and translates this information to dimmer levels for red, green, and blue light sources.  The mix between the three sources sets a proportional color, or mix.   The proportions are maintained throughout the range of levels, ensuring accurate color at any brightness.

Connect red to DimA, green to DimB, and blue to DimC.

In this mode, DimD is not the HSL white channel.  Instead, it is directly controlled by the DMX channel assigned for DimD.  Thus, this mode provides a 3-color HSL engine and one general purpose dimmer.

For best results when using HSL mode with multiple fixtures and light sources, RC4 ColorMatchTM should be used to correct and match color palettes.

HSL -> DimA/B/C/D (RGBW) [BAB][Mode 5]

DimA
DimB

All 4 dimmers are controlled by the HSL engine.  Connect red to DimA, green to DimB, blue to DimC, and white to DimD. The mix between the four sources sets a proportional color, or mix.   The proportions are maintained throughout the range of levels, ensuring accurate color at any brightness.

For best results when using HSL mode with multiple fixtures and light sources, RC4 ColorMatchTM should be used to correct and match color palettes.

Flkr -> HSL -> DimA/B/C (RGB), DMX -> DimD [ABB][Mode 6]

DimA
DimB

The RC4 Wireless Flkr Engine modulates the HSL color controller. The 4th output of the Flkr Engine is not used.

The HSL controller output drives DimA,B, and C for RGB control.  DimD is is directly controlled by the DMX channel assigned to it.

For best results when using HSL mode with multiple fixtures and light sources, RC4 ColorMatchTM should be used to correct and match color palettes.

Flkr -> HSL -> DimA/B/C/D (RGBW) [BBB][Mode 7]

DimA
DimB

The RC4 Wireless Flkr Engine modulates the HSL color controller. The 4th output of the Flkr Engine is not used. The HSL controller output drives all 4 dimmers for RGBW control.

For best results when using HSL mode with multiple fixtures and light sources, RC4 ColorMatchTM should be used to correct and match color palettes.
