I. Configuring the DMXpix with the console
A. The console being used in this example is a Zero 88 Fat Frog in wide mode with 48 channels
B. A DMXio transmitter is being used
C. A two channel DMXpix dimmer is being used
D. This process uses Enhanced RC4 OneTouchOneTouchRC4 OneTouch uses DMX channel levels to represent channels and curves, which are then adopted by a dimmer when a single small button is pressed. Back in 1993, James David Smith, chief product designer at RC4 Wireless, envisioned a day when wireless dimmers would be so small that there would be no room for rows […]

1. See RC4 Custom Pixel Profile OneTouch Settings for a complete outline of available parameters.
E. A 300-pixel string of LED tape is being used, but the DMXpix is generating data for 500 pixels on each port (A and B)
1. 500 pixels is 1500 channels
2. 1500 channels is 3 universes
3. This is all handled by the DMXpix
F. Determine the chip type being used on the LED tape
1. In this case it is a Vivid RGB string that uses WS2812 chips
II. Configuring the parameters on the DMXpix
A. Start with all channels on the consoles down, at zero
B. On the channel where you will be starting your keyframe, set the level for the correct string type
1. In this case, we are strarting at DMX channel 1 and using a level of 75% to set WS2812
C. On the next channel (2 in this case) set the keyframeKeyframeKeyframes are a user-definable range of DMX channels used to create visual effects with pixel strings. The keyframe and the replication method are the core elements of patented RC4 Custom Pixel Profiles. A keyframe can use a fraction of a DMX universe and control hundreds of pixel LEDs with live creative control of the entire […]

D. On the next channel (3 in this case) set the groupingGroupingGrouping is one of several parameters in RC4 Custom Pixel Profiles in DMXpix and LumenDimPix pixel drivers. It allows multiple physical pixels to be mapped to one control pixel. This is just one of several ways to control more pixels with fewer channels using patent-pending RC4 technology.

E. On the next channel (4 in this case) set the type of replicationReplicationRC4 Custom Pixel Profiles provide various methods for expanding and extending a keyframe of pixels beyond it’s basic length. These are replication methods. The simplest replication method copies the keyframe end to beginning, over and over again, for the length of the string.

F. 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 […]

III. Changing the color order on the first dimmer channel of the DMXpix
A. On the first channel (1 in this case) on the console, set the chip type again
B. To avoid having to set any of the other parameters again, be sure all other channels are down, at zero
C. Using a small tool like a bent paper clip, tap the Set A button on the LumenDimPix
D. Cycling through the color order is done by tapping the Set A button repeatedly
1. The color that appears on the tape when Set A is tapped indicates the first color of the new color order
2. When you see pixels lit red, you know that is the first color
3. For every first color, there are two possible color orders. In this case it could be red/green/blue or red/blue/green. Raise the 2nd and 3rd channels to confirm it is red/green/blue. If not, continue tapping Set A until red appears again.
IV. Configuring the second dimmer channel
A. All channels must be down
B. In this example, the second dimmer channel starts on DMX channel 25 on the console
1. On channel 25 set the string/ chip type
2. On the next channel (26 in this case), set the keyframe length
3. On the next channell (27 in this case) set the grouping size
4. On the next channell (28 in this case) set the type of replication
C. Using a small tool like a bent paper clip, tap the Set B ButtonSet B ButtonAll RC4 dimmers have Set buttons for each individual dimmer output. The second button is the Set B 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 […]

IV. Changing the color order on the second dimmer channel of the DMXpix
A. Leave all channels as they are, still representing the desired settings
B. Using a small tool like a bent paper clip, tap the Set B button on the DMXpix
C. Cycling through the color order is done by tapping the Set B button repeatedly
D. The entire chain of pixels is now controlled from 24 DMX channels, which are RGB for 8 pixels (8 pixels x 3 colors = 24 DMX channels) which is one row of faders on our Zero 88 demonstration console
1. The keyframe can be any length of pixels from 1 (unison mode) to 170 (1:1 mode).
