OPERATION OVERVIEW
Function
Note: For an overview of Dual I/O Module components, refer back to
The Dual I/O Module handles video conversion and dimming of the video outputs, while also providing genlock and
EDID management to the Mac Pro computer. The module also handles DMX512 conversion to Art-Net and Art-Net/
sACN transmission to the computer.
The I/O Module allows the video signal to be easily reconfigured to work with many display devices without the need
for an external scan converter. The module receives two DVI outputs from the computer and uses these two signals
to provide two separate output sections with DVI and HD-SDI preview, and DVI, VGA, and HD-SDI stage outputs. The
two output sections are functionally identical, but are independent so that each can be configured for its own output
requirements.
During operation, the I/O Module can dim the stage outputs to full black so that "inappropriate" content - such as the
Mac desktop or Mbox Designer application windows - will not be displayed on the stage outputs (e.g., when in window
mode).
Notes:
+
The I/O Module's format conversion is purely a change from one signal type to another. During video conversion
there is no change to resolution, scaling, or position. The I/O Module will always output the same resolution and
frequency that the computer is outputting; provided that resolution and frequency are compatible with the output
signal type (see below).
+
The module can blackout or partially dim the video output signals to levels below full brightness. This can be done
from the control console (or Mbox Director), from the Mac computer, or by using the Stage Blackout and/or Preview
Dim switches on the front of the I/O Module.
+
The I/O Module's DVI inputs are single-link, meaning that the maximum resolution of the I/O Module's inputs and
outputs is 1920 x 1200.
+
The DVI outputs on the I/O Module are DVI-D (digital) only and do not have any analog signal.
+
There are only a few possible resolution and frequency combinations that are compatible with conversion to HD-SDI,
so depending on the computer's output resolution/frequency the module may not be able to output a signal.
+
The I/O Module's HD-SDI outputs are 1.5G. Only the following formats are supported for output:
-
SMPTE 259M: NTSC 480i @ 59.94Hz, PAL 576i @ 50Hz
-
SMPTE 292M: 720p @ 59.94/60Hz, 1080i @ 50/59.94/60Hz, 1080p @ 24/25/29.97/30Hz
Note: The I/O Module's HD-SDI does not support output of 720p @ 50Hz.
