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 6-1).

  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 6-1):
