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.

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.

www.ti.com

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.

Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms.

No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
