一、 Precautions
Please read all instruments before use, otherwise the product
may be damaged.
1) The optical module is in the device and the circuit board is exposed, so do not
drop it from a height.
2) This device contains high-precision optical components, so please do not
disassemble without authorization.
3) The module is powered by 12V power supply. A 12V, 10A or higher current
adapter is suitable. Otherwise, it may cause the adapter to overcurrent and power off
when the brightness is increased.
4) DMD flat cable connector has a limited service life, so it is not allowed to unplug
the cable without authorization.
5) It is strictly forbidden to Unplugging the DMD flat cable when the module is
power on condition. This will damage the DMD.

四、 Instruction
4.1 Product Description
This module is mainly for structured light application. It can project 2D
chessboard patterns and 1D 1bit and 8bit structured light patterns. The functions of
ordinary projectors have been simplified and cannot be used.
Please note: Since this module functions have been cut down compared to the TI
official module, not all of the functions of the official GUI can be realized. In addition,
the TI official firmware is not suitable for this module, so please use our firmware.
Specific instructions can refer to the TI official document “DLP Display and
Light Control EVM GUI Tool User Guide (Rev. A)”. Other differences from TI
official DLP3010EVM are explained below.
4.2 Software and Documents
4.2.1 Software
Control software GUI: https://www.ti.com/tool/cn/DLPDLC-GUI
Firmware: The firmware of OPR407 series DLP4710LC module is not
compatible with the TI official one. Please use our company firmware and the
compression package will be send to customers after purchasing our products.
API: DLPC34XX-API

The DMD used by OPR407 series DLP module is DLP4710LC, so please select
the DLP4710LC version software.
4.3.2 Others
Please install other softwares as needed. This document does not describe in
detail.
4.4 Hardware connection
4.4.1 Driver Installation
When connecting for the first time, the driver will be automatically installed on
the Internet. The completion of the installation is prompted as following.

4.5 GUI Instruction
4.5.1 Connect module to computer
Connect the power plug to the power connector J10, and the plug model is
43645-0200. The load current of the power supply wire should be more than 10A, and
18AWG or higher wire is recommended. The supply voltage is 12V, and supply
current is 10A. The maximum power of the high-power version of DLP4710LC is
100W. If the power supply is insufficient, the module will shut down automatically.
Use USB Type-C cable to connect computer and DLP4710LC module.
Please use our GUI installation package, or download the latest vision from TI
website. Download address: https://www.ti.com.cn/tool/cn/DLP4710EVM-LC. Note:
The GUI downloaded from the official website may be incompatible with our module
and causes problems.
After connecting the module to the computer and the power supply, open the
GUI software.
Check if the connection button at the bottom left has a green symbol. If not, click
the text in the red box in the above figure, and it will become the green checkmark,

13
which means connection is normal.
Click the "Get" button to check the drivers and firmware information. It is
recommended to click this button after module is power on.
4.5.2 "Display" mode to test patterns and images
The "patterns and images" tab in "Display" mode is projection control for the

14
build-in test images.
"Test patterns" is about the build-in test patterns for DLPC chips, which do not
change with firmware changes. The options under "pattern" can control the projection
patterns, and "foreground" and "background" can set the foreground and background
colors. After the settings are completed, click the "Set" button to project.
The "splash image" is about the images to be projected. They vary with different
firmwares. Customers can change them according to their needs. For the modification
method, please refer to the "Make Firmware" section. Select the image needed and
click "Set" button to project.

15
Under the "Video and color" tap, "Video information" is for the external input
signal projection. This function need customers to develop video signal decoder to
realize.
"Color temperature" is to adjust color temperature. Not recommended for
customers.
"Display settings" tap is for the image transformation and distortion correction.
Not recommended for customers.

16
The options under the "IntelliBright" tap are for intelligent brightness
optimization. Not recommended for customers.
The parameters under the "LED current" tap are to adjust the light brightness
manually. Selecting the different colors’ enable boxes can turn on the related LED
light. Click "set" button to confirm. However this function will reset when the
projection pattern option is set, and doesn’t work at the "internal patterns" mode.
Dragging the pointer on the bar under different colors and clicking "Set" button
can change the brightness. The relation between the current and the pointer position
on the bar varies at different module because of different light sources. So please note
that the values displayed in the boxes are not the real values. One module values
cannot be used as the references for another modules. To acquire the available values,
the advanced control mode is needed, which will be introduced in the later section.

17
4.5.3 "light control" mode to customize stripe patterns
In "Light control" mode, the functions under "external patterns" label need
external video signal decoder to realize. This part need to be developed by customers.
Our product does not support following function.
"Internal patterns" tap is the setting of the customized structured light projection.

18
GUI supports 1 bitmap and 8 bitmap. Please pay attention to matching of image
bits and vertical/ horizontal direction when adding patterns. If the added stripes do not
match the options, the projected stripes will be wrong. Stripe image formats are
available in BMP or PNG.
To add horizontal stripes to the projected image, you need to select a single
vertical stripe, that is, a 1x1080 resolution image.
Similarly, to add vertical stripes to the projection image, you need to select a
single horizontal stripe image, that is, a 1920x1 resolution image.
