6 Quick-Start Procedure

This quick-start assumes default conditions as shipped.

1. Power up the DLP3010 Light Control EVM by applying an external DC power supply (19-V DC, 3.42 A)

to the J10 connector. The P5V_VIN (D5) and P3P3V_SB (D6) LED will turn on to indicate that 5-V and

3.3-V standby power is applied.

External Power Supply Requirements:

• Nominal output voltage: 19-V DC

• Minimum output current: 3A; Max output current: 3.42 A

• Efficiency level: VI

NOTE: TI recommends using an external power supply that complies with applicable regional safety

standards such as UL, CSA, VDE, CCC, PSE, etc. A DC Power Connector 2.5mm x 5.5mm is being

used on the DLP3010 Light Control EVM Main Board.

NOTE: The system is designed to operate also with an external 12-V DC power supply.

2. Move the SW_ONOFF switch to the ON position to turn the DLP3010 Light Control EVM on. When the

DLP3010 Light Control EVM is turned on, the PROJ_ON LED D3 will turn on.

3. After the DLP3010 Light Control EVM is turned on; the projector will default to displaying a DLP Light

Control splash image.

4. The focus of the image can be adjusted on the optical engine.

Figure 4. Optical Engine with Focus Adjustment

5. Connect USB to the DLP3010 Light Control EVM and open the DLP3010 Display and Light Control

Graphical User Interface (GUI) on your computer. If needed, connect an HDMI source to the EVM and

communicate to the EVM over the GUI software.

6. 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 J11 on the DLP3010 Light Control EVM Main

Board to set Trigger IN/OUT voltage on the EVM. This jumper is required to gain access to the trigger

signals. The jumper is not included by default.

7. 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

SW_ONOFF before disconnecting the power.

There are ten indicator LEDs on the DLP3010 Light Control EVM, and they are defined in Table 2:

7.3 DLP3010 Light Control Trigger Description

(1) Install Jumper J11 to set Trigger IN/OUT voltage on the EVM (Jumper is not included by default). For 3.3-V signal level: Connect

pin 2 and p 3 of J11. For 1.8-V signal level : Connect pin 1 and pin 2 of J11.

(2) See IMPORTANT note below.

For light control applications: Reserved for external trigger signal (Input).

Applicable to Internal Pattern Streaming Mode only.

The 3DR pin on the DLPC3478 can be used as a 3D left or right

reference indicator or as trigger input signal for light control application. A

jumper on J3 has to be installed to determine the use case for this pin.

For display application: Connect pin 1 and pin 2 of J3.

For light control application: Connect pin 2 and pin 3 of J3.

TSTPT_4(2) 7 TSTPT_4_BF Output TRIG_OUT_1 signal.

GPIO_06 3 GPIO_6_BF Output Pattern Ready signal. Applicable to Internal Pattern Streaming Mode only.

GPIO_07 4 GPIO_7_BF Output TRIG_OUT_2_signal.

IMPORTANT: .

The Rev A Display Boards use a level shifter which changes the incoming signal level to

1.8 V. The correct voltage level for the DLP controller is 3.3 V. If EVM does not detect the

input signal correctly, modify the placement of resistors R32 and R35.

• Rotate R35 to disconnect pull-up resistor from the 1.8-V supply.

• Connect free end of R35 to 3.3 V. The 3.3-V connection at R32 can be used.

8 EVM Setup

The DLP3010 Light Control EVM is composed of three parts:

• DLP3010 Light Control main board

• DLP3010 Light Control 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

DLP3010 Light Control GUI, HDMI, audio, and the connector for the DLP3010 Light Control display board.

The main board also contains a switch to turn on the projector in case the DLP3010 Light Control display

board and the engine are connected. Figure 5 shows the main connectors on the main board.

Figure 5. DLP3010 Light Control Main Board

The DLP3010 Light Control Display board has three main connectors: The LED connector, the flex cable

connector, and the main board connector. The main and display board connect together via J5 and J9.

Note that the main board connector J5 on the DLP3010 Light Control Display board is on the bottom,

while the LED and flex cable connectors are on the top as shown in Figure 6.
