Pixel Driver Pixel Grouping (RC4MagicPC Software/DMXpix)

I. RC4 Custom Pixel Profiles handle 3 parameters

A.  grouping allows multiple physical pixels to be mapped to one control pixel

1. Grouping is achieved using the console or software; in this example, we are using RC4MagicPC Software

II. One to one (1:1) pixel control

A. Click on the DMXpix tab on the RC4MagicPC Software

1. Select DMX 1:1, which sets sequence length is set at 170 (one entire DMX universe), and group size is 1 (1 physical pixel for each control pixel)

2. Pixel Driver A is set to DMX start channel 1.

3. Pixel Driver B is set to DMX start channel 256.

4. Pixel Driver A and Driver B are configured with the same sequence length/ group size numbers

5. Click ‘send pix settings to all units’ button

B. Click on the Virtual TX tab to check this ratio

1. In this example the top row of faders start at DMX channel 1. When raised, the first channel is red in the first pixel of pixel string A, the second channel is green in that same pixel, and the third channel blue

2. The bottom row of faders start at DMX channel 256. , When raised, the first channel is red in the first pixel of pixel string B, the second channel is green in that same pixel, and the third channel blue

3. When done, click ‘all off’ to bring all faders to zero

III. One to two (1:2) pixel control

A. Click on the DMXpix tab

1. Sequence length is set at 170, which is one DMX Universe

2. Group size is 2

a. This means that each pixel on the DMX controller controls two pixels, side by side, on the pixel tape.

3. Pixel Driver A and Driver B are configured with the same sequence length/ group size numbers

4. Grouping is the only value that has changed

5. The visual effect displayed on the pixel string will now become twice as wide

6. Click ‘send pix settings to all units’ button

B. Click on the Virtual TX tab to check this ratio

1. On the top row of faders, when raised, the first channel is red for two pixels, second channel is green for two pixels, and so on.

2. Likewise on the bottom row of faders, when raised, the first channel is red for two pixels, second channel is green for two pixels, and so on.

3. When done, click ‘all off’ button to return all faders to zero

III. Different pixel groups on each pixel string

A. Click on the DMXpix tab

B. On Pixel Driver A

1. Sequence length is set at 170, which is one DMX Universe

2. Group size is 9

a. This means that each pixel on the DMX console will control a row of 9 pixels on the pixel string.

C. On Pixel Driver B

1. Sequence length is set at 170, which is one DMX Universe

2. Group size is 4

a. This means that each pixel on the DMX console will control a row of 4 pixels on the pixel string.

3. Click ‘send pix settings to all units’ button

D. Click on the Virtual TX tab to check this ratio

1. On the top faders, when raised, the first channel is red for 9 pixels side by side, the next channel is green for those 9 pixels, and so on

2. On the top faders, when raised, the first channel is red for 4 pixels side by side, the next channel is green for those 4 pixels, and so on

3. When done, click ‘all off’ button to return all faders to zero

IV. If you have multiple pixels performing in the same area, you might want an equivalent color spread in a physical space

A. The grouping function allows users to create matching color lengths, even if the physical pixel sizes of two strips is different, or the pixels are different distances apart

V. Unison mode enables all pixels to be the same color

A. On the DMXpix Tab, select Unison; it is located under the DMX 1:1 listing.

1. Choose Unison on both Pixel Driver A and Pixel Driver B

2. Click ‘send pix setting to all units’ button

3. All 500 pixels are now configured to respond together

B. Click on the Virtual TX tab to check this ratio

1. Click the ‘all off’ button

2. On the top faders, when raised, the first channel turns all the Driver A  pixels red; the second channel turns all pixels green and the third channel turns all pixels blue

3. On the bottom faders, when raised, the first channel turns all the Driver B pixels red; the second channel turns all pixels green and the third channel turns all pixels blue

4. Unison mode allows all pixels to be a single color using only three channels

a. It is a time saver when a designer is uncertain if they want a single color for all pixels, or single pixel control, or anything in between

VI. The Grouping function enables the use of fewer channels along a longer length of tape.
