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 (
