This document describes the Unitek USB-C Bi-Directional Switch, a versatile device designed to manage USB-C connections for various applications, including data transfer, video output, and power delivery. The manual provides a comprehensive overview of its functions, technical specifications, usage features, and maintenance information.
Function Description
The Unitek USB-C Bi-Directional Switch acts as a central hub for managing USB-C connections, offering both "Two In One Out" and "One In Two Out" functionalities. This means it can either allow two host devices to share one display or enable one host device to switch between two displays or USB-C 10Gbps data ports. The device supports bi-directional switching, allowing users to switch between inputs and outputs seamlessly.
Key functions include:
- USB-C Bi-directional Switching: The core function allows for flexible switching between two input sources to one output, or one input source to two outputs. This is crucial for setups where multiple devices need to share a single peripheral or display, or a single device needs to interact with multiple peripherals.
- DP Alt Mode Bi-directional Switching: The switch supports DisplayPort Alternate Mode, enabling bi-directional switching for video output. This is particularly useful for high-resolution displays, as it supports up to 8K@60Hz resolution transmission. This feature ensures high-quality video output for demanding applications.
- USB PD 100W Transmission: The device supports Power Delivery (PD) up to 100W, allowing for power output lossless switching. This means connected devices can be charged efficiently without interruption during switching, making it ideal for laptops, tablets, and other power-hungry USB-C devices.
- USB 10Gbps Data Transmission: The switch facilitates two-way switching for USB 10Gbps data transmission. This ensures fast and reliable data transfer between connected devices, supporting Thunderbolt peripheral data transmission and PCIe signals. This high-speed data capability is essential for external SSDs, docking stations, and other data-intensive peripherals.
- Key Switching: The device features a physical key for convenient manual switching between the two inputs or two outputs, providing a simple and intuitive user experience.

Status Indication:
- LED Indicators: The switch includes LED indicators to show the current status. A white LED indicates the active input/output. When switching, the corresponding LED lights up, providing visual feedback to the user.
Physical Interfaces:
- Key Switch: A physical button for manual switching.
- Input or Output: USB Type C Female (USB-C 1): A female USB-C port that can function as either an input or an output.
- Input or Output: USB Type C Female (USB-C 2): Another female USB-C port, also capable of functioning as an input or an output.
- Input or Output: USB Type C Male (USB-C): A male USB-C connector, typically used for connecting to the host device or a primary peripheral.
- Power: USB-C Female (DC/5V): A dedicated USB-C female port for power input, ensuring stable operation of the switch and connected devices.
Usage Features
The Unitek USB-C Bi-Directional Switch is designed for ease of use and flexibility in various scenarios.
Two In One Out Mode:
- In this mode, two host devices (e.g., two laptops) can share a single display or peripheral. The user can switch between the two hosts using the key switch on the device. This is ideal for collaborative workspaces or setups where multiple computers need to access the same monitor, keyboard, and mouse (via a connected hub).
- The diagram illustrates two laptops connected to the switch, which then connects to a single display. The DC 5.0V power input ensures stable operation.
One In Two Out Mode:
- This mode allows one host device (e.g., a laptop) to switch between two displays or two USB-C 10Gbps data ports. This is useful for users who need to alternate between different monitors or connect to different sets of peripherals without constantly plugging and unplugging cables.
- The diagram shows a single laptop connected to the switch, which then connects to two different displays or peripherals. The "or" indicators highlight the flexibility of connecting to either display.
Application Scenarios:
- Multi-Device Workstations: Easily switch between a work laptop and a personal laptop sharing a single monitor, keyboard, and mouse.
- Gaming and Streaming Setups: Seamlessly switch between a gaming PC and a streaming PC using the same high-resolution display.
- Presentations: Connect a presenter's laptop to a projector or large display, while also having a backup device ready to switch to.
- Data Management: Switch between different external storage devices or docking stations connected to a single host.
- Content Creation: Utilize multiple monitors for different tasks, switching the primary display as needed.
Ease of Switching:
- The physical key switch provides a tactile and immediate way to change inputs or outputs, eliminating the need for software controls or complex configurations.
- LED indicators clearly show which input/output is currently active, preventing confusion.
Maintenance Features
The Unitek USB-C Bi-Directional Switch is designed for reliability, but proper care and awareness of its capabilities are important for long-term performance.
Troubleshooting 8K@60Hz Resolution:
- If your TV or monitor does not reach 8K@60Hz resolution, ensure that your host device supports DP1.4 alt mode.
- Additionally, verify that your display device supports the HDMI2.1 protocol. These are critical requirements for achieving the maximum advertised resolution.
Troubleshooting Cell Phone/Computer or Tablet Device Connectivity:
- If your cell phone, computer, or tablet device does not connect to the product or output video screen normally, confirm whether the device's Type C port supports video output.
- Some electronic devices' Type C port only supports data and charging functions, not video output. Refer to the product brand's official website for specific device parameters and specifications.
Troubleshooting Slow Reading and Writing Data:
- If you experience slow reading and writing data speeds, ensure that the USB3.2 (10Gbps) standard transmission speed is being utilized.
- If the read/write speed is slow, make sure that the USB port/storage device/data cable connected to the host computer is up to the 10Gbps version.
- In addition, some 10Gbps M.2 hard disk enclosures are not recommended to use a long cable to connect this product, because too long cable will affect the 10Gbps signal transmission. It is recommended to use a 20-30cm cable to connect the M.2 hard disk enclosure to maintain optimal speed.
