InLine 33380V network card Ethernet 1000 Mbit/s

Four independent Gigabit LAN ports via USB:Ideal for virtualisation, network segmentation or redundant connections – each port can be used independently.
Optimised for professional applications:Supports VLAN tagging, QoS, time synchronisation (IEEE1588) and jumbo frames – ideal for demanding IT infrastructures.
High compatibility & flexibility:Compatible with Windows, Linux and macOS – enables use in a wide range of industrial and server environments.
Plug & Play with intelligent USB technology:The integrated VL820 chip enables reliable data transfer at up to 5 Gb/s via USB 3.2 Gen.1.
Compact form factor & robust design:Fits into any IT environment – ideal for embedded systems, server cabinets or mobile diagnostic tools.

The InLine® USB-A 3.2 Gen.1 to 4x RJ45 Gigabit Ethernet Adapter expands professional IT systems with four full-featured, independent LAN interfaces. Whether for virtualisation, multi-NIC configurations, network segmentation or diagnostic systems, this adapter offers reliable Gigabit Ethernet connectivity in a compact form. Thanks to the USB 3.2 Gen.1 interface with up to 5 Gb/s transfer rate, the four ports can be connected to the host system via a single USB cable – without additional power supply or driver installation under common operating systems.
The integrated Realtek and VIA chipsets guarantee stable, high-performance data transmission and offer professional features such as VLAN tagging (IEEE802.1Q), Quality of Service (IEEE802.1P), precise time synchronisation (IEEE1588v1/v2), flow control and jumbo frame support up to 9 KB. Automatic crossover detection and extensive offload functions ensure additional performance and system relief.
Ideal for servers, industrial PCs, embedded systems or mobile use in maintenance and network diagnostics, this adapter is the perfect tool for IT professionals who depend on flexible, reliable network solutions.

How to use

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.

Recommendations

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.
