5 Quick-Start Procedure

This quick-start procedure considers default conditions as shipped.

  1. Power up the DLP LightCrafter Display 471TP EVM by applying an external DC power supply (19-V DC, 4.74A) to the J1 connector.

    External Power Supply Requirements:

    • Nominal Output Voltage: 19 VDC
    • Minimum Output Current: 2.5 A
    • Maximum Output Current: 4.74 A
    • Efficiency Level: VI
    • Connector Barrell Size: 2.5 x 5.5 x 8.25 [ID x OD x L(min)] mm
    • Connector Polarity: Center +
Note:
  • TI recommends using an external power supply that complies with applicable regional safety standards such as UL, CSA, VDE, CCC, and PSE.
  • The P19VIN (D3), PWRGOOD (D5) and POSENSE (D8) LEDs on the Formatter board will turn on to indicate that input and standby powers are applied.
  1. Move SW1 switch to the ON position to turn on the DLP LightCrafter Display 471TP EVM. When the DLP LightCrafter Display 471TP EVM is turned on, the POSENSE (D8) LED will turn off and PROJ_ON LED (D7) will turn on. The HEARTBEAT LED (D8) will start blinking.
  2. After the DLP LightCrafter Display 471TP EVM is turned on, the projector will default to displaying a DLP LightCrafter Display splash image.
  3. The focus of the image can be adjusted manually on the optical engine.

  4. Connect the USB to the DLP LightCrafter Display 471TP EVM and open the latest GUI on your computer. If needed, connect an HDMI source to the EVM and communicate to the EVM via the GUI software.
  5. When turning off the projector, turn off the SW1 switch prior to removing the power cable.
    Note: To avoid potential damage to the DMD, it is recommended to turn off the projector with the SW1 switch before disconnecting the power.

There are eight indicator LEDs on the DLP LightCrafter Display 471TP EVM (Formatter and Front-End boards), and they are defined in Table 5-1.
