VC-Grid Safety and Installation Guide
If a VC-Grid module is set to individual pixel control (see “Setting modules to grouped or pixel control
modes” on page 19), LEDs are given DMX addresses using a ‘left-to-right, then down’ numbering system
(like the reading order you are using for the words on this page). For example, if one VC-Grid RGB module
is set to pixel control and set to DMX address 1, each of the 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 a VC-Grid module is set to module control (see “Setting modules to grouped or pixel control modes” on
page 19), it can be controlled as an individual module or assigned to a group of modules. To create a group
of modules, give them 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 Martin M-PC™
Using an RDM-compliant DMX controller such as Martin M-PC™, 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
• Apply various setup options.
To use Martin M-PC, connect a PC running this application to the data link using the Martin USB Duo™
USB/DMX interface box.
See Figure 10. Open the
RDM View
window in M-PC and click on the
Scan
button (arrowed bottom left) to
display a list of the RDM-compliant devices on the DMX/RDM data link (in this example, ten VC-Grid RGB
modules are present on the link, and all ten modules are set to DMX address
1
).
Identifying VC-Grids in the installation
To see which VC-Grid module in this list corresponds to which VC-Grid module in the installation, click on
each VC-Grid module in the list once to select it, then click on the
Identify
button at the bottom of the
screen. The VC-Grid in the installation that corresponds to the selected VC-Grid in the list will flash a signal
so that you can identify it.
