Using the DLP4710EVM-LC Light Control Evaluation Module
6. Connect USB to the DLP4710 Light Control EVM and open the DLP4710 Display and Light Control
Graphical User Interface (DLPDLC-GUI) on your computer. If needed, connect an HDMI source to the
EVM and provide external video input.
Note: When providing HDMI input from an external source for Light Control applications, ensure that
the external source provides input of resolution 1080p (1920x1080). Some laptops/desktops provide
720p (1280x720) resolution input by default, which can result in broken images in External Pattern
Streaming mode, as only 1080p resolution is supported in Light Control modes.
7. Via the GUI the EVM can be set to Video Display Mode or Light Control Modes. Refer to the GUI
user's guide for further description.
Note: Install Jumper J7 on the DLP4710 Light Control EVM to set the needed Trigger IN/OUT voltage
on the EVM.
8. When turning off the projector, push ON/OFF switch (SW21) and then move slide switch (SW28) to the
OFF position prior to removing the power cable.
CAUTION
To avoid potential damage to the DMD, be sure to turn off the projector using
the sequence listed in
before disconnecting the power.
There are eleven LED indicators on the DLP4710 Light Control EVM (
