DepthEngine T100 User Manual
1. General Description
The purpose of this user manual is to familiarize DepthEngine T100 module users with the
software, including the basic operation of TOF GUI, setting of parameters, import and export data,
various display and control elements.

2. Hardware Introduction
To explain more clearly about the hardware of DepthEngine T100 module, we opened the front
cover, which is a 850nm infrared light filter. Make sure there is no obstacles near the VCSEL when
in use, or it may shield the light.

Figure1. Components of the DepthEngine T100 module

2.1 VCSEL
As we can see in Figure1, there is one VCSEL as the illumination light source. Compared with led,
it has the advantage of uniform light, which can also provide a better measurement in image
edge. The VCSEL device is designed at Class 1 during normal operation. However, we still
recommend users do not look direct into the VCSEL when it is working.

2.2 USB Interface
This module use USB Type-C as the communication and power interface. Actually, it’s an USB 2.0
slave device. Considering that the working current of this module can up to 1A, we recommend
users plug this module to USB3.0 host device(Typically USB2.0 can provide 500mA current while
USB 3.0 can provide up to 1000mA).

3. Installation and setup
3.1 VCP Driver Install
If host system is windows10, this step can be skipped.
If host system is windows 7/8, then choose the corresponding driver shown as below.

Figure2. VCP driver list
After VCP driver is installed, then connect the DepthEngine T100 module to windows PC with USB
Type-C cable. The device manager can show this module name in ports list(The port number
maybe different). See in Figure3.

4. GUI Functionality
4.1 Overview
The TOF GUI is free installation and support hot plug. It consists of two windows: The control
window Figure4 and the display window FIgure5. The control window is used to set parameters,
choose the way of displaying the camera images and to log data. It can auto detect DepthEngine
T100 module after device plugged in.

Figure4. Control window

Figure5. Display window
Most of the functions are self-explaining and are not described herein.

4.2 Operating mode and display setting

Displays connected device type.
The text box in left window can show some
information of the device when click
start button.
Show chip temperature.
DRNU_LUT: Choose whether to use the DRNU
calibration data or not.
HDR: Only depth and point cloud mode can
use HDR. User should disable HDR before
change to amplitude and grayscale mode.

Figure6. Display setting

4.2.1 Min Amplitude
When the amplitude of one pixel is lower than this, the distance of that pixel will not be
calculated.

4.2.2 Integration Time
Range 0 - 4000us. The longer the integration time, the farther the measurement distance. At the
same time, frame rate will decrease for heat and safety consideration.

4.2.3 HDR 2nd
Range 2000 - 4000us. Only when HDR box is checked can this parameter be set. Meanwhile, the
range of integration time(used as HDR 1st ) is changed to 0 - 2000us.

4.2.3 Frame Mode
Change to another frame type.

4.2.3.1 Depth
When left-click the depth image, the depth value of that point will show on text box. The same
with amplitude and gray-scale frame mode. See in Figure7.

Figure7. Show depth value
When pixel is over exposure or low amplitude, the distance can not be calculated. It will show NA
on text box.

4.2.3.2 Point Cloud
Use left mouse button to rotate the image.
Use mouse wheel to zoom in and zoom out the image.
Use control + left mouse button to move the image.

Figure8. Show point cloud

4.2.4 Log Data
Click this button to save image and data. It can be found in /TOF_GUI/log/1013_40_689. The
name of this directory is consist by machine ID, wafter ID and chip ID. See in Figure9.

Figure9. Log data
In text file , it records total 160x60 values. In depth mode, the meaning of this values explained as
below:
Pixel value logged

Meaning

Value < 30000

Normal, Depth = Value/2 (unit: mm)

Value = 65300

Low amplitude, Depth = NA

Value = 65400

Over exposure, Depth = NA

Value = 65500

ADC overflow, Depth = NA
Figure10. Value meaning

4.2.5 Update Firmware
To get the best performance of this device, users can update its firmware when new update is
available. This can be checked in https://github.com/DepthEngine/. After new firmware is
downloaded to local disk. Click the update button, the device will enter bootloader mode. If
users want to cancel update at this time, just close the update firmware window. The device will
come back to working mode. Choose the directory where the firmware is located. Then click send
button, the firmware will be downloaded to device. After finished, the device will come back to
working mode automatically. Users need to repress start button. See in Figure 11.
