NVIRONMENTS
In most live environments you need the ability to quickly and easily switch between
the various live feeds. MXProDV serves this need well because you can view the four
input sources on the Preview screen and easily run transitions from the CURRENT to
the NEXT feed simply by pressing
PLAY
or moving the

ONITORING
MXProDV also serves well for monitoring security cameras. For example, you might
set up four different cameras and train them on areas that require security coverage.
The Preview screen shows small images from each camera. Switch to FULL Preview
(
SHIFT
+3 ) to see larger previews from all cameras. When you want to see a full screen
image of a specific area, simply press the
CUT
button for that camera.

GPI D
EVICE
You can connect a GPI (General Purpose Interface) device to MXProDV. The GPI
device can trigger an event from an external source, such as a push-button switch or
an edit controller with GPI output. A GPI device is especially useful when you are
positioned some distance away from MXProDV but still want to be able to control its
operation.
A GPI pulse causes MXProDV to behave exactly as if the play button were pressed.
Normally, it starts a transition you previously set up. If you are playing back a
Learned sequence (see Chapter 11, Learn Mode), it triggers the next event in the
sequence.
An edit controller or computer that provides a contact closure can also serve as a GPI
triggering device.
WARNING
Do not connect a power source of any kind to the Control GPI input
connector on the MXProDV. Doing so can damage the equipment and void
your warranty.
You can use a remote push-button device to trigger events on MXProDV. If you
already have a GPI device you want to use, refer to “Live Broadcast Configuration”
on page 38 to learn how to connect the device. If you do not have a GPI device but
would like to build one, refer to the instructions in the next section.
