4.1 Физикалык байланыш
- USB кабелин туташтыруу: Insert the USB Type-B end of the provided USB 3.1 cable into the USB 3.1 Gen 1 port on the adapter. Connect the USB Type-A end to an available USB 3.1 (or 3.0/2.0) port on your computer.

4.1-сүрөт: USB 3.1 Gen 1 Type-B port for host connection.
- Ethernet кабелин туташтыруу: Connect a standard RJ45 Ethernet cable from your network router, switch, or wall jack to the RJ45 port on the adapter.

4.2-сүрөт: RJ45 Gigabit Ethernet port with LINK/ACT and SPEED LEDs.
4.2 Драйверди орнотуу
For Windows operating systems, the adapter is designed for "Plug and Go" functionality, meaning drivers typically install automatically upon connection. For Linux and Mac OS X, built-in drivers are often available, or specific drivers may be required depending on your system version. Refer to the Coolgear website for the latest driver information if automatic installation does not occur.
4.3 Mounting Kit Installation (Optional)
The included mounting kit allows for secure installation of the adapter. The adapter slides into the bracket, which can then be affixed to a surface using screws or other appropriate fasteners. This is particularly useful for industrial or fixed installations.

4.3-сүрөт: Adapter shown with its detachable mounting bracket.
5. Операция
Once connected and drivers are installed, the adapter will automatically establish a network connection. Observe the LED indicators on the RJ45 port for status:
- LINK/ACT LED:
- Катуу жашыл: Indicates a successful network link.
- Кыпкызыл жашыл: Indicates network activity (data transmission).
- SPEED LED:
- Катуу янтарь: Indicates a 100 Mbps connection.
- Катуу жашыл: Indicates a 1000 Mbps (Gigabit) connection.
- Өчүк: Indicates a 10 Mbps connection.
- PWR LED: (Located near USB port)
- Катуу жашыл: Түзмөк күйгүзүлгөнүн көрсөтөт.
