User Manual
FAQ
What operating systems does this USB Ethernet adapter support?
The adapter provides native compatibility with Windows 7 and newer versions, Windows Server editions, macOS 10.14+, Linux Kernel 2.6.25+ (Long-Term Support versions only), and Chrome OS. Most modern operating systems recognize the device automatically without requiring driver installation, though a driver CD is included for systems that need it.
Can both Ethernet ports operate simultaneously at full Gigabit speed?
Yes, both RJ-45 ports support simultaneous Gigabit Ethernet operation at up to 1000 Mbps each. The USB 3.0 interface provides sufficient bandwidth (5 Gbps) to handle both ports at maximum capacity along with the USB pass-through port, ensuring no performance bottlenecks during concurrent network usage.
Does this adapter require external power or is it bus-powered?
The adapter is completely bus-powered through the USB 3.0 connection, drawing all necessary power directly from the host device. This eliminates the need for external power supplies or adapters, making deployment simpler and more portable. The design complies with USB power specifications for reliable operation.
What is the purpose of the USB 3.0 pass-through port?
The USB 3.0 pass-through port allows you to connect another USB device (such as a flash drive, external hard drive, or peripheral) while using the Ethernet functionality. This enables device chaining without requiring an additional USB hub or occupying another host port, effectively expanding connectivity options from a single USB connection.
What enterprise networking features does this adapter include?
Beyond basic connectivity, the adapter supports Wake-on-LAN for remote power management of connected systems and VLAN tagging for network segmentation in managed switch environments. These features make it suitable for business and IT deployments where advanced network configuration and remote administration capabilities are required.
How does the Auto MDIX feature work with this Ethernet adapter?
Auto MDIX (Automatic Medium-Dependent Interface Crossover) automatically detects whether a straight-through or crossover Ethernet cable is connected and configures the port accordingly. This eliminates the need for specific cable types, allowing you to use any standard Ethernet cable for connection to switches, routers, or other network devices without manual configuration.
