Data Sheet


What is Thunderbolt™ 3?
Thunderbolt™ 3 is the most powerful and faster interface with a data transfer rate of up to 40Gbit/s. Thunderbolt™ 3 uses a Type-C™ form factor connector with can be flip over just like a standard USB-C connector. It can also support single video signals output up to 5K@60 Hz or dual 4K@60Hz video output and provide power delivery (PD) to recharge your laptop up to 100 W. Thunderbolt™ 3 also available to have a daisy chain feature to connect up to 6 devices.
Thunderbolt™ 3 Type-C™ or USB Type-C™?
Thunderbolt™ 3 uses the USB Type-C™ port, but not all devices and cables support Thunderbolt™ 3. This means that a USB Type-C™ device is compatible with the Thunderbolt™ 3 port, but a Thunderbolt™ 3 device is not compatible with a USB Type-C™ port. For this reason, make sure that your devices or notebooks support the Thunderbolt™ 3 standards. Please refer to the manufacturer's description or manual.
Compatibility with host computers?
Your notebook or MacBook® must have at least one Thunderbolt™ 3 port. If you're unsure whether this is the case, check your notebook, MacBook, or PC manual and look for information about the Type-C™ port. Your Type-C™ port on your notebook may be marked with a flash, indicating a Thunderbolt™ 3 Type-C™ port.
Can my notebook be charged via the DockingStation?
Yes, Thunderbolt™ 3 has power delivery support up to 100 watts. This is normally sufficient to charge a notebook. Depending on the DockingStation, for example, the power can only be 60 watts or 80 watts. Check with the manufacturers manual to find out what charging power your notebook needs.
How can I continue working with my closed notebook?
Windows® provides special settings that control how the notebook behaves when the lid closes.• You can make these settings in the power options.• Select Settings – System - Power & sleep.• Select "Additional power settings".• Go to “Choose what closing the lid does".• Select "Do nothing”.To keep the Mac® from shutting down when it's closed, the following actions are necessary:• The MacBook® must be connected to the power supply.• A mouse and keyboard must be connected.• A monitor must be connected.In this case, the MacBook® can also be used when closed.
No network connection via the DockingStation, but via the host computer. What is the problem?
It is possible that the LAN/WLAN is only released for a known MAC address. In this case, the MAC address of the DockingStation and notebooks must be equated, or the passthrough of the MAC address of the notebook must be enabled. You can usually make this setting in the BIOS of your notebook.
Can the notebook be charged via a USB 3.0 port?
No, from the technological point of view this is not possible.
How do I know the MAC address of the DockingSstation?
- Connect the DockingStation to the running Windows® computer and connect the LAN cable, switch the DockingStation on if necessary.
- Right click on the Windows® icon in the lower left corner.
- Select the "Run" field.
- Enter cmd and confirm by pressing OK/ENTER.
- Write ipconfig/all and confirm by pressing the ENTER key.
- The connected network devices with MAC address are now displayed.

- Connect the DockingStation to the running MacOS® computer and connect the LAN cable, switch on the DockingStation if necessary.
- Click on System Report.
- Click on Network.
- Select the appropriate device. The MAC address is displayed below.
Can I use another Thunderbolt 3 cable?
Yes, another cable can be used as long as it is a Thunderbolt™ 3 cable! A USB Type-C™ cable cannot be used!
Why is my notebook not charging even though the DockingStation is connected?
Your notebook does not support Power Delivery or has special charging requirements. Please contact your notebook manufacturer to find out which standard is supported.
The DockingStation is not detected by the notebook or PC?
Check if your system's Thunderbolt™ 3 drivers are up to date.
The displayed image from the DockingStation is jittering or flickering.
• This may occur if the framerate is set incorrectly. Check your system’s settings. For example, if 59 Hz is set, change it to 60 Hz. The same applies to 29 Hz, to be set here to 30 Hz.• If the problem persists, try using a high-quality cable.
When the DockingStation is connected to the Mac, the following message appears: "Thunderbolt accessories cannot be used: Connect the unit to the Thunderbolt port on this Mac". What could be the reason?
-This message could be caused by using the wrong cable. Please check if you are using a Thunderbolt™3 cable (marked with a flash at both ends) and not a normal USB type-C™ cable. If possible, please use the included ICY BOX Thunderbolt™ 3 cable.-The message may also appear if you are using a Thunderbolt™ 3 device with a USB Type-C™ port. Also if a DockingStation, which only supports USB Type-C™, is connected to a Thunderbolt™ 3 port.
The screen flickers on external monitors with my MacBook Pro 16" 2019, what can I do?
If you experience this problem, it can be solved by a firmware update. Please contact our customer support at The screen usually flickers once about every 10 seconds.
The notebook is charged very slowly or is not charged at all.
The DockingStation has two Thunderbolt™ 3 ports, but only one of them can provide enough power to charge your notebook. Please connect your notebook with the Thunderbolt™ 3 cables to the Thunderbolt™ 3 Type-C™ port with the flash and notebook. This port supports up to 85 watts. The second port, which is only marked with the flash, only supports a maximum of 15 watts, which is not enough to charge the notebook.
Can the power supply be deactivated?
No, the charging function of the power supply cannot be deactivated.
Is it possible to connect 3 monitors?
Yes, Windows® 10 supports up to 3 monitors if the notebook screen is switched off instead. On MacOS® up to 2 monitors are supported.
Are 144 Hz resolutions supported?
No, only resolutions up to 60 Hz are supported.
It is not possible to set a 4K resolution at 60 Hz.
First, make sure that the monitor supports this resolution. -Furthermore, when connected via HDMI®, the HDMI® cable must also support 4K 60 Hz (HDMI® 2.0 or higher). When connecting via DisplayPort™, be sure to use the DisplayPort™ standard 1.2 or higher to enable 4K 60 Hz. This applies to monitor and cable as well.
