4 What is in the DLP4710 Light Control EVM ?
The DLP 4710 Light Control (Figure 2) consists of three subsystems:
1. Optical module includes the optics, red, green, and blue LEDs, and a 1920 x 1080 (1080p) DMD
capable of 600 lumens out-of-the-box.
2. DLP driver includes the DLP chipset comprising of the DLPC3479 controller and DLPA3005 PMIC/LED
driver. It includes a header to access Trigger IN/OUT signals for camera capture and other system
controls.
3. System front end includes MSP430, ITE HDMI receiver, USB-Serial Bridge Controller and several
connectors for external inputs (such as HDMI and USB).

5 Optical Module
The optical module in the EVM is developed by Young Optics and is production ready. The optical module
consists of the following components:
• 0.47-inch 1080p DMD (DLP4710)
• OSRAM P1W red, green and blue LED
• This optical module interfaces with the EVM using DMD pin mapping Option 2. Please refer to the
DLPC3479 datasheet for more information about the DMD interface.

6 Quick-Start Procedure
This quick-start assumes that the EVM default conditions are as shipped.
1. Power up the DLP4710 Light Control EVM by applying an external DC power supply (19 V DC, 4.74 A)
to PWR_IN connector (J28).
External Power Supply Requirements:
• Nom Output Voltage: 19 VDC
• Max Output Current: 4.74 A
• Efficiency Level: V
NOTE: TI recommends using an external power supply that complies with applicable regional safety
standards such as UL, CSA, VDE, CCC, PSE, etc.
2. Move SW28 (PS_ON/OFF) slide switch to the ON position.
LEDs D43 (+3.3V) and D57 (INTZ) light up to indicate 19 V power is applied.
3. Push ON/OFF switch SW21 to turn on the DLP4710 Light Control EVM.
LEDs D36 (SYS_ON-OFF), D33 (M_IRQ) and D34 (S_IRQ) light up to indicate that the DLP4710 Light
Control EVM is turned on.
4. After the DLP4710 Light Control EVM is turned on, a DLP Light Control splash image will be projected.
5. The focus and zoom of the image can be adjusted on the optical module (Figure 3).

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 Section 6 before disconnecting the power.
There are eleven LED indicators on the DLP4710 Light Control EVM (Table 2):
