RGB PIXEL CONTROL MODES
This feature gives the user the ability to adjust the RGB pixel control mode of the device. Individual
pixels may be controlled independently for finer control over the resolution of the device’s light-
ing display. Alternately, multiple individual pixels may be grouped together under a common set of
control channels in order to reduce the number of required control channels. This also reduces the
effective pixel count for each fixture, thereby allowing an increased number of fixtures to be operated
off of the same driver port (see the Driver Output Limitations section). The downside to this is the
reduced resolution of the lighting display.
In each pixel control mode, the first number denotes the number of control groups that LEDs will be
divided into, while the second number denotes the number of individual LEDs that will make up each
control group. Each control group will always occupy 3 DMX channels (for Red, Green, and Blue
control). This means that within each control group, all LEDs will be controlled by the same set of 3
DMX channels.
For example, when operating a Pixel Bar 30IP, selecting 15x2 mode means that the fixture’s LEDs
will be divided into 15 RGB control groups, with each group containing 2 LEDs. See the illustration
below:
In this mode, a total of 45 DMX channels are used: 3 DMX channels (for Red, Green, Blue) per group
multiplied by 15 groups.
If there are not enough unused DMX channels available to accommodate this set-up, one possible
solution is to select a pixel control mode that will decrease the number of control groups. For in-
stance, selecting 10x3 mode will result in the LED display being divided into 10 RGB control groups
each containing 3 LEDs. Therefore, the number of DMX channels required drops to 30: 10 control
groups multiplied by 3 DMX channels (for Red, Green, and Blue) per group. See the illustration be-
low:
Available pixel control modes for each Pixel Bar IP model are shown on the next page.
