22 VC-Grid Safety and Installation Guide
Calculating the number of DMX channels required
A VC-Grid installation uses the three DMX channels required by each element (individual pixel, module or
group of modules) multiplied by the total number of elements in the installation. For example, an installation
containing fifty VC-Grid 8x8 RGB modules will require:
• 3 DMX channels if the entire installation is controlled as one group,
• 3 channels x 10 groups = 30 DMX channels if the installation is divided into ten groups that are controlled
individually,
• 3 channels x 50 modules = 150 DMX channels if each of the fifty modules is controlled as an individual
group, and
• 3 channels x 50 modules x 64 pixels = 9600 DMX channels if each of the 3200 pixels is controlled
individually (in this example, 19 DMX universes will be required because one DMX universe has 512
channels).
Pixel and module modes
If you set a VC-Grid to pixel mode, each pixel on the module is controlled individually (apart from the
VC-Grid 16x16, where pixels are controlled in groups of four).
If you set a VC-Grid to module mode, all the pixels on the module are controlled together as one group.
The interfaces of RDM-compliant controllers vary depending on the producer, but you should be able to find
the pixel and module mode options in the Settings or Options area of your controller.
Individual and grouped control can be mixed freely in an installation. For example, some VC-Grid modules
can be set up for individual pixel control, other modules can be set up for individual module control, and
other modules can be put into groups for grouped control of multiple modules.
DMX addresses
To prepare an installation for DMX control, you need to set it up using an RDM-compliant DMX controller so
that each individually controlled element (pixel, module or group of modules) will receive instructions from
the controller on its own DMX channels. The DMX address (also known as the control address or start
channel) is the first of these channels. If an element requires more than one DMX channel, it uses the DMX
address channel and the channels immediately above it. For example, if you set a VC-Grid RGB module to
module mode so that you control all its pixels as one group, and if you set it to DMX address 1, it will use
DMX channels 1 - 3. Channel 4 will be available for use as a DMX address for the next device.
If you set a VC-Grid to pixel mode so that you can control individual pixels, its LEDs use DMX addresses
according to a ‘left-to-right, then down’ numbering system (like the reading order of the words on this page).
For example, if one VC-Grid 8x8 RGB module is set to pixel control and set to DMX address 1, each of the
module’s 64 LEDs will use 3 channels, and the module will use DMX channels 1 - 192 (Channel 1 -3 for the
top-left pixel, channels 4 - 6 for the next pixel on the right etc. until it reaches channels 190 - 192 for the last
pixel at the bottom on the right. Channel 193 will be available for use as a DMX address for the next device.
If you set a VC-Grid to module mode so that you control it as one module, it will use three DMX channels as
described above. If you want to create a group of modules that you always control together, give all those
modules the same DMX address. All modules that have the same DMX address will receive the same
instructions and behave identically.
Setting up via RDM
Using an RDM-compliant DMX controller, you can communicate with the VC-Grid modules on the DMX data
link via RDM. You can:
• Retrieve data
• Set the DMX addresses of the groups or pixels on the link
• Set modules to grouped or pixel control modes (see above)
• Apply various setup options.
See the controller’s user manual for details of how to retrieve information from and send commands to the
VC-Grid.
