Interface card adapter InLine 33380V
The InLine 33380V USB-A 3.2 Gen.1 to 4x RJ45 Gigabit Ethernet adapter provides four independent Gigabit LAN ports via a single USB connection. Designed for professional IT environments, the compact adapter delivers full-featured Ethernet interfaces for virtualization, multi-NIC setups, network segmentation and mobile diagnostics without requiring an external power supply.
Each of the four ports operates independently and supports Gigabit speeds through the integrated VL820 USB controller together with Realtek and VIA chipsets. The adapter is plug & play on common operating systems and offers features expected in professional setups, including VLAN tagging (IEEE802.1Q), Quality of Service (IEEE802.1P), IEEE1588 time synchronization, flow control and jumbo frame support up to 9 KB. It also supports automatic crossover detection, extensive offload functions (NDIS5/6, LSO v1/v2) and energy-efficient operation (IEEE802.3az).
Connect the adapter to a host computer using a USB-A 3.2 Gen.1 port or a compatible USB 2.0/1.1 port. Attach Ethernet cables to the four RJ45 ports; each port will be recognised by the operating system as an independent network interface. No additional power supply is required. On supported systems (Windows, macOS, Linux) the adapter installs automatically or uses native drivers; for specialized server OS versions check vendor driver availability if needed.
For optimal performance, use a USB 3.2 Gen.1 port on the host and shielded Cat5e or higher Ethernet cables. Configure VLAN, QoS and jumbo frame settings on both the adapter and connected switches when deploying in segmented or high-throughput networks. Ensure the host system supports the required offload and checksum features to benefit from reduced CPU load.
