I .Accessing special feature dimmer curves using RC4 Enhanced OneTouch (requires firmware version 4.080 / 2.80.x.x or higher)

A. Enhanced OneTouch provides all available dimmer curves starting at channel level 20 (absolute decimal level 20, not 20%)

1. A value of 20 on a channel assigns 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 […]

3. A value of 22 on a channel is the linear dimming curveLinear dimming curveA linear dimming curve is directly proportional to the DMX channel value on a console. If the DMX channel is at 50%, the power being delivered to the light source will be 50%.

4. A value of 30 (not 30%) selects the AC wave generatorAC wave generatorAn AC wave generator creates alternating current (AC) using direct current (DC) electronics and special software.  In RC4 Series 3 dimmers, this is done using two 2 DC dimmers in tandem.  AC power is needed to make a telephone ring, or make EL wire light up.  It is the kind of power that comes from a regular […]

II. Using DMX channel 25 with the AC wave curve

A. Manually set channel at 30 (not 30%) on the console

1. Only 1 channel should be up for this process.  All other channels should be at zero.

2. The channel that is up is the channel that is being assigned.  The level of the channel selects the dimmer curve.

B. Power up the RC4Magic dimmer

1. DMX data must be present for OneTouch to work.  The yellow LED indicates data is present.

C. Using a small tool like a paper clip, push 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 […]

1. The two lights will alternate blinking back and forth, indicating the A and B channels are ganged together and being controlled by the AC wave generator
