I. Setting DimC (the third dimmer) to 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%.

A. The channel should be set at 70% to indicate the linear curve

B. In this example, it is being done on channel 10

C. Recap: Set Channel 10 (the channel) to 70% (to select the linear curve).

D. Using a small tool like a bent 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 […]

E. The dimmer should remain on, at 70% brightness, after pressing the button.  If not, then streaming DMX data is not present.

II. Move DMX channel 10 up and down on the console to test

III. The DimC LED indicator will show the dimmer level (it is directly connected to the dimmer itself)

IV. If any channel lower than channel 10 was up, the dimmer will assume that channel, rather than 10.  The first channel that is above 15% will be assigned to the dimmer
