Dual I/O Module
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 functions as a "dual" unit since it provides two independent output sections. These sections are noted in
the drawing below as "Server Output 1" and "Server Output 2."
Note: This is intended to be an overview of the Dual I/O module components. For more information regarding module
operation, refer to

Output to Stage
Stage Outputs - The module provides three (3) stage outputs: VGA, DVI, and SDI. The intensity level of these stage
outputs can be mastered by the Camera fixture. The stage output may also be suppressed in the case of a system
crash.
Stage Blackout - When this switch is set to "Yes," the stage outputs will be blacked out. When active, the middle
switch causes the preview outputs to dim in parallel with the stage outputs. The right-hand switch controls the EDID
capture functions of the I/O module.
Preview Outputs - The module provides two (2) preview outputs: DVI and SDI. The preview outputs are for local
monitors and are not affected by the hardware dimmer in the Dual I/O module (controlled by the intensity channel on
the Camera fixture).
Preview Dim - When this switch is set to "Yes," the preview will mimic the stage output.
EDID Capture - This switch is used to read and capture data from any EDID (Extended Display Identification Data)
compliant device.
Genlock In/Out - The Genlock ports are used with the Generator Lock function, which syncs all Mbox Extreme
servers in the system so they will begin drawing frames at the same time. Genlock Input and Output connectors are
provided on both output sections, however, only the top pair of Genlock connectors are active. (Note that the Genlock
Out is not a pass-thru. This output should only be used if the Mbox Extreme server is the master for syncing (rather
than using it as a daisy-chain port).
