04INTRODUCTION
1.5 FRONT VIEW
NOTE: There are two LEDs on the bottom of the OWC Thunderbolt 3 Dock near the front,
which are not pictured. Their functionality is described below.
1. Data LED (green) — This LED glows green when the dock has an active data connection to a computer
via the Thunderbolt cable. If the computer is powered off or in sleep mode, this LED will power off.
2. Power LED (blue) — This LED glows blue when the dock receives power. Unlike some Thunderbolt devices,
the Thunderbolt 3 Dock does not power off when disconnected from the computer or when the computer
sleeps. As long as the dock receives power, the blue power LED will remain on.
3. microSD card slot — Accepts microSD media cards.
4. SD card slot — Accepts SD type media cards.
5. Combo audio port (3.5 mm) — Accepts microphones, headphones, and headsets.
6. High-power USB 3.1 Gen 1 port — Connect compatible USB devices via Type-A connector.1
7. USB 3.1 Gen 2 port (Type-C) — Connect compatible USB devices via Type-C connector.
USB HIGH-POWERED PORTS
These USB 3.1 Gen 1 ports are each capable of providing up to 1.5A of power for charging devices such
as the Apple iPad. These ports are otherwise identical to the USB 3.1 Gen 1 ports located on the rear of the dock.

2. S/PDIF Digital Audio port (output only) — Connect S/PDIF device here.
3. Gigabit Ethernet port — Connect an Ethernet cable here to access a wired network.
4. Thunderbolt 3 ports — Connect one port to the Thunderbolt host; you must connect to the
dedicated Power Delivery port (right) to charge the host. Use the extra port to connect up to five
additional Thunderbolt devices, plus a display. Thunderbolt 3 supports DisplayPort 1.2 over USB-C.
See Section 2.2 for display usage notes.
5. Mini DisplayPort — Connect your display here. This connection supports DisplayPort 1.2.
See Section 2.2 for display usage notes.

06CONNECTION & USAGE NOTES
CONNECTION & USAGE NOTES
2.1 CONNECTION
1. Connect the Thunderbolt 3 Dock to power using the included power supply and cable.
2. Connect the dock to a Thunderbolt port on your computer using either one of the Thunderbolt
ports on the dock.
3. Connect other devices to the appropriate ports on the dock. All connected devices will be available
immediately for use on your computer.
2.2 USAGE NOTES
- Mac: To enable support for the Apple Super Drive, Apple USB Keyboard, and charging for iPad 1/2/3
generation devices on the dock’s ‘high-power’ ports, please install the Dock Ejector application for
Mac. This application includes a driver that enables support for these devices and charging functions.
go.owcdigital.com/dockejector
- There is no power switch on the dock. As long as it is connected to power and to a computer, the dock
will function. If the computer powers off or sleeps, the dock will remain powered on, but all other devices
connected through the dock will power off or sleep, as if they were connected directly to the computer.
- The dock and all of its ports support hot-plugging. To ensure no data is lost, always eject or unmount
any connected storage devices from your operating system before disconnecting them from your dock
(or before disconnecting the dock from the host computer).
- The Combo audio port on the front of the dock is analog. The S/PDIF port on the back of the dock
is digital, but it is output only.
- Thunderbolt 3 is backwards compatible with earlier versions of Thunderbolt when using the appropriate
adapter, such as an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter. Use this type of adapter
to connect a Thunderbolt 2 or Thunderbolt device to the Thunderbolt 3 Dock. Note: to avoid operating
at reduced speeds, all Thunderbolt 3 devices should be at the front of the device chain, where TB3 =
Thunderbolt 3, TB2 = Thunderbolt 2 and TB = Thunderbolt (e.g. TB3 Host > TB3 device(s) > TB2 or TB
device via adapter > additional TB2 or TB devices).
- Thunderbolt device chains can support up to six Thunderbolt devices, thus five additional Thunderbolt
devices can be chained to the Thunderbolt 3 Dock. A Thunderbolt 3 display (or a display connected
via a USB-C display adapter) can be added to the end of a Thunderbolt 3 device chain.
- USB ports are bootable only on 2017 and later Macs using macOS 10.12.2 or later.
Thunderbolt and Ethernet are bootable on all Macs with a Thunderbolt port.
- Note that it is possible to connect other types of displays such as HDMI and DisplayPort
to the available Thunderbolt 3 port, so long as you have the appropriate USB-C display adapter
(e.g. you could use a USB-C to HDMI adapter, connected to the Thunderbolt 3 port).
- The Thunderbolt 3 Dock can support a single 5K display running at 60Hz.
- The refresh rates available at 4K will depend on the display connections used. To achieve 4K @ 60Hz
on two displays, one display must be a native USB-C display and the other a native DisplayPort /
Mini DisplayPort display.
- Dual 4K display setups that include a native Thunderbolt 3 display were not available at the time
of this writing. The Apple Digital AV Multiport Adapter and the Apple USB-C VGA Multiport Adapter
are both supported by the Thunderbolt 3 Dock.

07INSTALLATION
2.2 USAGE NOTES (CONTINUED)
PERFORMANCE NOTES
- For the USB Type-A ports on the back of the device, connecting to only one of them will allow for
maximum performance. As you plug in additional USB devices to the other ports, the bandwidth will
be shared among them.
- The USB Type-A port on the front shares bandwidth with the audio port and the media card readers.
For the best performance with this USB port, make sure you are not using the audio port or media
readers at the same time.
- The USB-C port on the front does not share bandwidth with other ports and has a maximum throughput
of ~8Gb/s.
- When working with media cards, it is not possible to use both readers at the same time.

08SUPPORT RESOURCES
3.1 TROUBLESHOOTING
Begin your troubleshooting by verifying that the power cable is connected to the OWC Thunderbolt 3 Dock
and to a power source. If the power cable is connected to a power strip, make sure that the power switch
on the strip is turned on. Next, verify that both ends of the Thunderbolt (USB-C) cable are properly plugged
into the computer and the dock. If the dock is still not working properly, try using a different Thunderbolt
cable or using another Thunderbolt port on the computer or the dock. You can verify if the dock is commu-
nicating with the computer by opening System Information and clicking on the ‘Thunderbolt’ category in the
sidebar. If the dock is seen by the computer but one or more connected devices are not, troubleshoot each
device individually. If problems persist, please contact OWC technical support.
