四、Operating Manual
4.1 Product description
OPR305 series module are made for structured light projection, they can project
several 2D build in test patterns and programmable 1D 1bit or 8bit patterns.
Attention: OPR305 series module are different from TI DLP3010EVM-LC,
some functions of TI GUI will not be supported. The firmware of DLP3010EVM-LC
can not work on our system. Please use the firmwares from our website.

Please use DLP3010LC with OPR305 series module.
4.4 Operating instructions
4.4.1 drivers install
Once first attached OPR305 series module to PC, some drivers will
automatically installed on your PC.
4.4.2 connection of OPR305 series module
Use a USB A to USB typeC cable connect OPR305 series module to PC, connect
the module to 12V power source, and then open DLP3010LC.exe . If the connection
is correct, you will see EVM Status;Test Pattern Generator on the lower left side of
GUI window. Click once one more on the green button will disconnect the module.
Click on the “get” button will get some information of the module.
4.4.3 Lens adjustment and fixation
As the figure below, there two objects on the lens can be adjusted. Focusing
knob and locking screw. Adjusting the focusing knob to make the screen more clearly,
and then lock up the locking screw to fix the lens.

4.5 software Operating instructions
OPR305 series module are made for high speed structure light projection, in this
case, the patterns will preinstalled into flash onboard, and operating in “internal
patterns” mode.
4.5.1 pattern sets set up
Patterns sets are set up for putting several similar patterns into one place, and
then they could use one parameter setting.
The max patterns number can be placed in one pattern set is listing below:
1D Pattern Type Max # of Patterns
8-bits vertical patterns 6
8-bits horizontal patterns 8
1-bits vertical patterns 51
1-bits horizontal patterns 64
Click “light control” tab
Click “internal patterns”
On the the Pattern Sets page, user can add or delete pattern sets and add or delete
patterns to and from each pattern set. Apreview window on the right shows the pattern
selected. Click Next on the bottom-right or any of the tab (Pattern Order or Pattern
Control) on the left to continue.

11
4.5.2 add 1d pattern
Tips:1d pattern stands for patterns that have grayscale varies only in one
direction.
GUI supports only PNG and BMP format.
The resolution of DLP3010 is 1280 x 720, user should add pattern just one pixel line.
For horizontal pattern sets, please add 1 x 720 pattern.
For vertical pattern sets, please add 1280 x 1 pattern.
If patterns added correctly, you will see pattern showed on the right side. User can
only add 1bit or 8bit pattern in pattern sets. 24bit colour pattern is not supported.

12
4.5.3 pattern’s timing setting
OPR305 series have only blue light source, in illumination setting, user can only
set to B.
Exposure time stands for module projecting time, pre-exposure dark time and
pose-exposure dark time are set for module to prepare, they can not be too short. If the
timing user sets are not supported, a window will show up to tell user which part need
to change when user click the “Program and load” button.
You will see more information in 《DLP3010EVM-LC Firmware Release Notes》
After timing setting, click “Program and load” button to program all the patterns
into flash.

13
4.5.4 pattern control
On the Pattern Control page, users can configure the trigger out, trigger in and
pattern ready signals and to control the display of patterns in internal pattern mode.
This page requires the EVM to be connected to the GUI in order to work.
Configure the triggers and pattern ready signal as required and click Set. To view
the current configuration of these signals, click Get. After all the configurations are
set, the user can select and control how to run these patterns:
run once, run continuously, pause, step, stop, reset
In trigger in mode, module project only one pattern when receive one trigger
signal.
The configuration take effect after click “set” button, but will lost after
disconnect the power source. If user wish to storage the configuration, could make a
batch file, and program it into a firmware, and then write it in flash.

14
4.6 LED brightness adjustment
4.6.1 LED switch
On display tab intellibright page, user could enable blue LED and adjust the
brightness of light source. Check enable and press set button to turn on the light
source. Move the current block and then press set button to set a new brightness.
Attention: user can not enable red LED and green LED.
4.6.2 Light source current adjustment under 4A
OPR305 series module have the max light source current of 5A. It is much
higher then the GUI presented. GUI programmed for TI DLP3010EVM-LC, the
current on GUI is not the same on our module.
In DLP system, there is a 10bit register storage the brightness message. It can be
adjusted from 0 to 1023. 0 stands for 0A, and 1023 stands for 6A on our module.
When operating OPR305 series module, user should not configure the current more
than 5A(850). In this GUI, when user move the block to the right side, and current
said 2500mA, in fact the number written into register is 700 about 4.2A on OPR305
module. The brightness is much higher than DLP3010EVM-LC, but still not the max
brightness of out module, to reach 5A (850) current, user could set it in advanced
mode.

15
①Connect OPR305 series module to PC with USB type C cable, and power up
the module. If connection is correct, user can click advanced button to get into
advanced mode.
②Click connection button to connect module in advanced mode.

16
③In illumination tab, there is a rgb led current window. Press get button to get
current number of the light source.
④Check “blue led enable” and type in a number between 0 to 850 and then
press set button to set a new brightness.
User can not check “red led enable” and ”green led enable”.

17
After user press “set” button, the new number will written into module, then
press “get” button will get the new number.
4.7 making batch file
Batch file is used for storage custom configurations into flash, so user could not
set the same configurations every time after powering up the module.
The way to make batch file will be show below, the batch file users make can not
be used directly, please contact Bopixel’s engineer to help you finish the batch file, so
you can compile it into your firmware.
①Connect OPR305 series module to PC with USB type C cable, and power up
the module. And press advanced button, to start the advanced mode.

18
②After starting the advanced mode, it will automatically connect to module.
③Click “batch command” on the left side, you will see all the commands are
listing below.
