5 Quick-Start Procedure
This quick-start assumes default conditions as shipped.
1. Power up the DLP LightCrafter™ Display 3010 EVM by applying an external DC power supply (5 V
DC, 3.0 A) to the J12 connector. Note: Use an AC-DC switching power supply which accepts 50-60Hz
100-240 VAC inputs, and outputs a nominal 5 VDC at maximum 3 A output current. The PWRON
(D16) and SYSPWR (D15) LED will turn on to indicate that 5 V power is applied
2. Move the SW_ONOFF switch to the ON position to turn the DLP LightCrafter Display 3010 EVM on.
When the LightCrafter Display 3010 EVM is turned on, the PROJ_ON LED will turn on.
3. After the DLP LightCrafter Display 3010 EVM is turned on; the projector will default to displaying a DLP
LightCrafter Display splash image.
4. The focus of the image can be adjusted on the optical engine.

5. Connect USB to the LightCrafter™ Display 3010 EVM and open the GUI on your Computer. If needed
connect a HDMI source to the EVM and communicate to the EVM over the GUI software.
6. When turning off the projector, turn off the SW_ONOFF switch prior to removing power cable. Note: To
avoid potential damage to the DMD it is recommended to turn off the projector with the SW_ONOFF
before disconnecting the power.
7. There are ten indicator LEDs on the DLP LightCrafter Display 3010 EVM (Table 2):

7 EVM Setup
The DLP LightCrafter Display 3010 EVM is composed of three parts:
• Main board
• DLP LightCrafter Display board
• Engine with LED connection and Flex cable
The main board contains the connector for the power supply, a USB connector to communicate to the
DLP LightCrafter™ Display software, HDMI, audio and the connector for the DLP LightCrafter™Display
board. The main board also contains a switch to turn on the projector in case the DLP LightCrafter™
Display board and the engine are connected. Figure 5 shows the main connectors on the main board.
Figure 5. DLP LightCrafter Display main board
The DLP LightCrafter™ Display board has three main connectors: the LED connector, the Flex cable
connector, and the main board connector. To connect the main board to the DLP LightCrafter™ Display
board, refer to Figure 6. Note that the main board connector on the DLP LightCrafter™ Display board is
on the bottom while the LED and Flex cable connectors are on the top.
