Setup Instructions
- Connect to Host Device: Plug the USB-C connector cable of the T'nB adapter into an available USB-C port on your computer, laptop, or smartphone. Ensure your device's USB-C port supports video output (DisplayPort Alternate Mode) for HDMI functionality.
- Connect HDMI Display: Connect an HDMI cable from your monitor or TV to the HDMI port on the T'nB adapter.
- Connect USB Peripherals: Plug your USB devices (e.g., mouse, keyboard, USB drive) into the USB 3.1 port on the adapter.
- Connect Power (Optional): If your host device requires charging or if you are connecting power-intensive USB devices, connect a USB-C power adapter to the USB-C PD2 port on the T'nB adapter. This will provide power passthrough to your host device.

Operating Instructions
Once connected, the T'nB Multiport Type-C Adapter operates automatically. Your operating system should detect the connected display and USB devices.
- HDMI Output: The adapter supports video output up to 4K resolution. You may need to adjust display settings on your computer (e.g., resolution, display mode - extend/duplicate) through your operating system's display preferences.
- USB 3.1 Port: This port provides high-speed data transfer for USB 3.1 compatible devices. It is backward compatible with USB 2.0 devices.
- USB-C Power Delivery (PD2) Port: This port is for power input only. Connect your original USB-C power adapter to this port to charge your host device while using the adapter. It does not support data transfer.
Maintenance
- Keep the adapter clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the adapter to extreme temperatures, humidity, or direct sunlight.
- Do not attempt to disassemble or repair the adapter yourself. This may void the warranty and cause damage.
- Store the adapter in a safe place when not in use to prevent physical damage.
Troubleshooting
- No display on HDMI monitor:
- Ensure your host device's USB-C port supports DisplayPort Alternate Mode (video output). Not all USB-C ports support this feature.
- Check if the HDMI cable is securely connected to both the adapter and the monitor.
- Verify that the monitor is set to the correct input source (e.g., HDMI 1, HDMI 2).
- Try connecting the adapter to a different USB-C port on your host device, if available.
- Restart your computer or host device.
- USB devices are not recognized:
- Ensure the USB device is properly plugged into the USB 3.1 port.
- If it's a high-power USB device, ensure a power adapter is connected to the USB-C PD2 port on the T'nB adapter.
- Try connecting the USB device directly to your computer to confirm it's functional.
- Host device is not charging via USB-C PD port:
- Ensure your USB-C power adapter is connected to the USB-C PD2 port on the T'nB adapter and is functioning correctly.
- Verify that your host device supports USB-C Power Delivery.
- Check the power output of your USB-C power adapter; it should meet or exceed the power requirements of your host device.
