MBOX ® STUDIO USER MANUAL 79
The following guideline assumes that you are using a second Ethernet port to output pixel-mapping and that the first
Ethernet port will be set to receive Art-Net to control Mbox.
+ Mbox pixel-mapping now uses the concept of Destinations (Dests) rather than universes. Dests may be numerical
Art-Net universes 0-255, numerical designators (257-999) for KiNET_DMXOUT power supplies, and numerical
designators with a port number (257.1 - 999.99) for KiNET_PORTOUT power supplies.
Note: In order to use the previsualization features and to output data, the "Pixel Map Enable" box on the Mbox Setup
tab must be checked. See
"Setup: Options" on page 38.
Setup
While in Window mode, select the Pixel Map tab at the top of the Mbox window. If there is no current pixel-mapping
file, you will see an empty configuration like the one below. If a pixel-mapping configuration already exists, then click
the New button and choose a name and save location for the new file.
The gridded area to the top left is the pixel-mapping context. This is where you will arrange your fixtures so as to
assign their pixels to various areas of the screen image. The grid lines are colored white every tenth division. The
fixture table to the right of the grid shows fixture patch and destination information. You may select a fixture on either
the grid or in the table; it will become highlighted in both places. Below the context grid you will find various controls
that modify the pixel-mapping setup.
The first step is to define how large your pixel-mapping context should be. Set this by modifying the values in the
boxes labeled "Context Width" and "Context Height." Trying to determine how large to make the context may be
difficult before you place your fixtures, however, it is possible to modify the size of the grid at any time. Each rectangle
on the pixel-mapping context not only represents an area of the screen image – the grid is laid directly over the video
image, which is divided accordingly – but additionally, each grid rectangle relates to one pixel on a patched fixture.
For the purposes of pixel-mapping, the screen image size is the same size as the Fullscreen mode selected on the
