About Thunderbolt 3
Thunderbolt 3 technology uses the USB-C connector, with bandwidth up to 40Gbps.
It supports USB 3.1, DisplayPort 1.2, PCI Express 3.0, Thunderbolt 2, rst-generation
Thunderbolt, and increased power delivery to connected devices.
Thunderbolt technology supports both video and data throughput. However, it
prioritizes video bandwidth to help ensure seamless display performance. The
performance of the remaining dock functions depends entirely on your display
conguration.
Thunderbolt 3 products must be used with Thunderbolt 3 cables.
About DP alt mode (DisplayPort alternative mode)
DP alt mode is a specication that allows a DisplayPort video signal to transfer over
USB-C. It enables the use of the USB-C interface for DisplayPort signals. Thunderbolt
3 supports the full USB-C standard, including support for DP alt mode. Because the
docking station supports DP alt mode, you can connect Thunderbolt 3 or USB-C based
video devices, cables, or adapters to the secondary Thunderbolt 3 port on the rear of
the docking station.
About USB power delivery 2.0
USB power delivery 2.0 is a specication that allows power (up to 100 watts) to be sent
over a USB-C or Thunderbolt 3 cable that supports the specication.
The TB3DK2DPWUE supports USB power delivery 2.0 prole 1, delivering up to 15
watts of power to each Thunderbolt 3 USB-C port.
Thunderbolt temperature
Due to the high-performance of Thunderbolt technology, Thunderbolt products
sometimes generate more heat than traditional hardware. Therefore, it’s normal for the
docking station to warm up when in use. Placing your laptop on the docking station’s
surface will result in even higher temperatures.
These higher temperatures do not represent a safety hazard to users or to hardware.
About USB 3.0 and USB 3.1 Gen 1
USB 3.0 is also known as USB 3.1 Gen 1. This connectivity standard oers speeds up
to 5Gbps. Any mention of USB 3.0 in this manual or on the StarTech.com website for
TB3DK2DPWUE refers to the 5Gbps USB 3.1 Gen 1 standard. Any mention of USB 3.1
Gen 2 refers to the 10Gbps Gen 2 standard.

About the docking station’s
USB-C (USB Type-C™) ports
Not all USB-C ports support the full functionality of the USB Type-C standard. Some
ports might only provide data transfer, and might not support video (DP alt mode) or
USB power delivery 2.0.
The docking station includes two USB-C ports:
• Front-panel USB-C port: This is not a Thunderbolt 3 port. It’s a USB-C port that lets
you connect peripherals using USB 3.0 (5Gbps) technology. This port supports data
throughput only. The port does not support DP alt mode or USB power delivery
2.0.
• Rear panel Thunderbolt 3 USB-C port(s): These USB-C ports are Thunderbolt 3
ports with a USB-C connector. One port is for connection to a host laptop, while the
second can be used as a Thunderbolt 3 port, or a USB-C port. When used as a USB-C
port, it lets you connect peripherals using USB 3.1 Gen 2 (10Gbps) technology. This
port supports DP alt mode, and USB power delivery 2.0 prole 1, up to 15W.
Note: Either of the Thunderbolt 3 USB-C ports on the docking station can be used to
connect to your host laptop.
About the docking station ports
The USB-A (USB 3.0) port located at the back of the docking station is a standard USB
3.0 throughput port. When the dock is connected to a host laptop, this port provides a
trickle charge to a selection of USB-charged devices.
The front USB-A (USB 3.0) port is compliant with Battery Charging Specication
Revision 1.2 (BC1.2), which means that you can use the port to connect and charge a
device faster than you can using a traditional standard USB 3.0 port.
This front USB 3.0 port can fast-charge a connected device even when the dock isn’t
connected to a host laptop. When the docking station is connected to a host laptop,
the front USB 3.0 port functions as a Charging Downstream Port (CDP), which has
simultaneous charge and sync capabilities.
The provided power adapter must always be connected to the docking station in order
to charge a device using the front-panel USB fast-charge port.

Install the docking station
The docking station is natively supported when connected to a compatible operating
system (see the System requirements section for supported operating systems).
It should automatically detect and install the required drivers once connected to a
Thunderbolt 3 port on your host laptop.
Follow the below sections and steps to properly set up the docking station.
Power the docking station
When the docking station is plugged in and powered, you can use USB power delivery
to power and charge your laptop through its Thunderbolt 3 USB-C port. The docking
station cannot receive power from the host laptop, so the power adapter must always
be connected to the docking station.
The docking station is congured to USB power delivery prole 1, providing
approximately 15 watts to each Thunderbolt 3 port. The rate at which the docking
station charges your laptop depends entirely on how much power the laptop typically
draws using its included power adapter.
1. Select the appropriate power cord for your region and connect it to the power
adapter.
2. Connect the power adapter to an AC electrical outlet and then to the docking
station’s DC IN (power input) port. The docking station should now be receiving
power.
Connect the docking station
1. Connect your external display(s) to the docking station (example, DisplayPort or
Thunderbolt 3 displays).
Note: See the Congure a display device section for dual-display conguration
requirements.
2. Connect your peripherals to the docking station (example, USB devices, RJ 45
network).
3. Connect the provided Thunderbolt 3 cable to a Thunderbolt 3 port on your host
laptop and to one of the Thunderbolt 3 USB-C ports on the docking station.
Note: Either of the Thunderbolt 3 USB-C ports on the docking station can be used to
connect to your host laptop.
Install the drivers
Once the docking station is powered and connected to your host laptop, the required
drivers should automatically install.
You might see a pop-up message requesting permission to allow the docking station
to connect to your computer. If you see this pop-up message, do the following:
