This video demonstrates standard RC4 OneTouch as found in all RC4Magic Series 2, RC4Magic Series 3, LumenDim, and W-DIM devices.  standard OneTouch has been the same in all RC4 dimmers since 2007.

I. Setting a dimmer to use the  ISL slow curveISL slow curveLEDs do not dim linearly: when dimmed to a linear 50%, they appear only slightly less bright than at 100%.  The level must drop to 25% to appear at half brightness.  To make LEDs appear linear, they must be controlled with the Inverse Square Law curve.  All good quality LED dimmers use this technique.  RC4 […]

A. ISL slow is the most commonly used dimmer curve for LEDs.  It provides RC4 Digital Persistence to emulate the thermal rise and fall of a conventional filament bulb.

B. ISL fast  curveISL fast curveLEDs do not dim linearly: when dimmed to a linear 50%, they appear only slightly less bright than at 100%.  The level must drop to 25% to appear at half brightness.  To make LEDs appear linear, they must be controlled with the Inverse Square Law curve.  All good quality LED dimmers use this technique.  RC4 […]

C. RC4 provides numerous dimming curves (see below for a link) for various kinds of loads and applications

II. To assign dimmer A to DMX channel 31

A. Set channel 31 to 30% (absolute decimal level 77)

B. Using a small tool like a paper clip, tap the Set A ButtonSet A ButtonAll RC4 dimmers have Set buttons for each individual dimmer output. The first button is the Set A button. On a 2-channel device these are Set A and Set B buttons. A 4-channel device adds Set C and Set D. The most common use of the Set button is to assign a DMX channel and […]

C. The DimA dimmer output indicator will come on at 30% brightness, indicating the channel assignment is complete

1. If the DimA indicator only comes on while the button is pressed, and it does not stay on, then streaming DMX data is not present.  The channel level from the console (channel 31 at 30% in this case) must be present, since this is the data that OneTouch uses to make the channel assignment.

D. When Set A is pressed, it assigns all 4 dimmers sequentially

1. Dimmer B is now on channel 32

2. Dimmer C is now on channel 33

3. Dimmer D is now on channel 34

4. This is useful when controlling LED tape, or in any case where sequential channels is desired (which is most of the time)

E. Set A is the only set-buttonSet buttonAll RC4 dimmers have a Set button for each individual dimmer output.  On a 2-channel device, these are SetA and SetB.  A 4-channel device adds SetC and SetD. The most common use of the Set button is to assign a DMX channel and dimmer curve to the associated Dim dimmer using RC4 OneTouch; SetA is […]

1. Set B will assign a DMX channel and curve to only Dimmer B

2. Set C will assign a DMX channel and curve to only Dimmer C

3. Set D will assign a DMX channel and curve to only Dimmer D

4. When non-sequential channel assignments are desired, use Set A first, then override the sequential series using Set B, C, and D

IV. Setting dimmer D to channel 10 with non-dim response

A. Set channel 10 to 100% (at full)

B. Using a small tool like a paper clip, tap the Set D ButtonSet D ButtonAll RC4 dimmers have Set buttons for each individual dimmer output. The fourth button is the Set D button. On a 2-channel device these are Set A and Set B buttons. A 4-channel device adds Set C and Set D. The most common use of the Set button is to assign a DMX channel and […]

C. The green Dim D indicator will come on at 100%, indicating the channel assignment is complete

D. The RC4 OneTouch dimmer curve selection chart outlines all available dimmer curve options and the levels that select each of them
