DUAL I/O MODULE
Operation Overview
Note: For an overview of Dual I/O module components, refer back to
The function of the Dual I/O module is to provide video conversion, final dimming of the video signal, and to send
EDID information to the Mac computer. The module also handles DMX512 and Art-Net input for the computer.
The module receives two DVI outputs from the computer and uses these two signals to provide two separate output
sections with DVI and SDI preview, and DVI, VGA (RGBHV) and SDI (HD & SD) stage outputs. The two output sections
are functionally identical, but are completely independent so that each can be configured for its own output
requirements. 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.
During operation, the I/O module can suppress the stage output so that "inappropriate" content - such as the Mac
desktop or Mbox Designer application frame - will not be displayed on the stage output (e.g., when in Window mode).
I/O module settings can be configured using the Mbox Setup tab as covered in
Notes:
+
During video conversion there is no change to resolution, scaling, or position, as it is purely a format change from
one signal to another.
+
There are fewer possible resolutions for SDI, so sometimes the module may not be able to output a signal.
+
The module can do a complete blackout or dim the RGB to levels below full output. This can be done by dimming
at the control console, from the Mac computer, or by using the STAGE BLACKOUT switch.
