DLP LightCrafter 4500 Module Overview
1.2 What is in the LightCrafter 4500 EVM?
The DLP LightCrafter 4500 module consists of two subsystems:
• Light engine – includes the optics; red, green, and blue LEDs; and the 912 × 1140 diamond pixel 0.45inch WXGA DMD, heat sinks, and fan. The light engine produces approximately 150 lumens at 15-W
LED power consumption.
• Driver board – includes the LED driver circuits, DLPC350 DMD controller, power-management circuits,
DVI-to-RGB conversion with the TFP401, and a 32-MB flash storage

1.2.1 Light Engine
iView Limited developed the IPD 1231 light engine for the DLP LightCrafter 4500. As shown in Figure 1-2,
the light engine includes:
• DLP4500FQE DMD
• DMD heat sink
• Red, green, and blue LEDs
• Focus control
• Projection lens
The iView Light Engine is mounted on top of a large thermal plate to cool the module. The DLP4500 DMD
is mounted vertically between the DMD heat sink and the light engine. On the opposite side to the DMD,
the red and green LEDs are mounted between a thermal plate and the light engine. The blue LED is
mounted between a thermal plate and the light engine, next to the projection lens. An LED heat sink is
mounted behind the red and green LED thermal plate and thermally connected to the blue LED thermal
plate. A fan forces air across the LED heat sink to cool the LEDs.
The light engine, not including the LED heat sinks, has a length of 90.5 mm, width of 73.7 mm, and height
of 23.6 mm.

912 columns by 1140 rows with the diamond pixel array geometry and configuration (see Figure 1-3 and
Figure 1-4). Due to the diamond pixel configuration, the array produces smooth diagonal lines, with jagged
vertical and horizontal lines, as shown in Figure 1-5. Two options exist to produce the vertical and
horizontal lines: use every row or column, or use every other row or column. When every row or column is
used, a more thick line is projected. When every other row or column is used, a more faint line is
projected.

1.5 DLP LightCrafter 4500 Jumpers
The DLP LightCrafter 4500 has jumper options to disable the onboard LED driver, control voltages of the
LED signals to an external board, and control the trigger input and output voltages. This section lists all
the jumpers on the DLP LightCrafter 4500 driver board. Figure 1-9 depicts the locations of these jumpers.
These jumpers require a 2-mm jumper, like Sullins Connector Solutions®SPN02SYBN-RC, Digi-Key part
number S3404-ND.
DLP LightCrafter 4500 Jumpers

This action is needed only if the DLP LightCrafter 4500 firmware becomes corrupted and must be
reprogrammed through the JTAG boundary scan or USB. The graphical user interface (GUI) firmware
upgrade process places the DLPC350 in bootloader mode through software commands and does not
need the jumper.
• J19: Device address select
– Jump across header to set I2C address to 0x3A and USB device serial number to LCR2.
– Do not populate jumper to set I2C address to 0x34 and USB device serial number to LCR2.
• J23: Hold in reset. Jump across header to drive and hold reset line low. Jumping across this header is
equivalent to pressing and holding the reset switch.
• J28: DLPC350 LED signals voltage selection. This jumper must be populated when bypassing the
onboard LED driver and using an external LED driver.
– Jump across pins 1 to 2 to set the DLPC350 LED enables and PWM signals to 3.3 V.
– Jump across pins 3 to 4 to set the DLPC350 LED enables and PWM signals to 1.8 V.
• J30: DLPC350 LED driver disable. This jumper must be populated when bypassing the onboard LED
driver and using an external LED driver.
– Jump across header to disable the onboard LED driver and turn off all LEDs, regardless of the DLP
LightCrafter 4500 video mode.
– Do not populate this header for normal operation using the onboard LED driver.
1.6 Dimensions
The DLP LightCrafter 4500 optical engine is mounted on top of a thermal plate to provide passive cooling
to the module. A heat sink and fan provide active cooling to the LEDs. The DLP4500, 0.45-in. DMD, is
vertically mounted at the end of the optical engine and attached with a flex cable to the driver board that
lies on top of the light engine. The dimensions of the DLP LightCrafter 4500 are of 98 mm long, 121.6 mm
wide, and 47.7 mm tall. Figure 1-12 shows DLP LightCrafter 4500 dimensions.

This chapter details the steps to power up the DLP LightCrafter 4500 and connect to a PC.
2.1 Power-up the DLP LightCrafter 4500
The DLP LightCrafter 4500 is ready to use, out of the box. Steps 1 through 5 show how to power, display
an image, and connect the device to a PC.
1. Connect a 12-V DC power supply to the power supply connector (connector 2 in Figure 1-8).
2. An LED on the bottom of the LightCrafter 4500 board, next to the flex cable lights up green. The fan
starts, stops, and then restarts while the DLPC350 is booting. After 5 to 10 seconds, the DLPC350
bootloads and displays a screen with the DLP and LightCrafter 4500 logo. The D4 LED on top of the
LightCrafter 4500 board flashes on and off green. If the board shuts down after briefly turning on the
display, the power supply current rating might be too low.
3. To display video, connect a DVI source to the mini-HDMI connector (connector 20 in Figure 1-8).
4. Control the DLP LightCrafter 4500 with the free GUI software (available to download from
http://www.ti.com/dlplightcrafter4500).
5. After installing the software on the computer, connect the PC to the DLP LightCrafter 4500 using a
USB to mini-USB cable (connector 4 in Figure 1-8). The first time the cable is connected on a PC, the
DLP LightCrafter 4500 emulates a USB composite device with human-interface device (HID) class. No
drivers are required because these drivers are natively handled by all operating systems.
