StarTech.com USB Network Adapter, USB 3.2 Gen1 Data Rate, 5V DC Supply Voltage - C21GA-USB-ETHERNET


This USB network adaptor provides wired Ethernet connectivity via a USB Interface for systems requiring a Compact network link. It connects devices to copper Ethernet networks, supporting both legacy and gigabit links while operating from a 5V DC supply. Designed for environments where a direct LAN connection is preferred over wireless, it integrates with standard network infrastructures and supports VLAN tagging for segmented traffic.

Features and Benefits:


• USB 3.2 Gen 1 link for high-throughput data transfer
• Supports 1000BASE-T for gigabit Ethernet performance
• Compatible with 100Base-TX and 10BASE-T networks for flexibility
• VLAN tagging implemented to separate network traffic
• Conforms to RoHS for restricted substances compliance

Applications


• Suitable for integrating automation controllers into wired LANs
• Ideal for electronics test benches requiring stable network access
• Used with industrial PCs to add gigabit LAN capability
• Can be used for configuration of networked electrical devices

What power requirements does it impose on host devices?


It draws its operating power from a 5V DC source supplied through the USB connection, so no external power adaptor is required.

Which Ethernet signalling standards does it handle for link negotiation?


It supports 10BASE-T, 100Base-TX and 1000BASE-T signalling, enabling autonegotiation across those speeds.

How does it assist with network traffic segmentation?


It implements IEEE 802.1q VLAN tagging to mark and segregate frames for organised network separation.

Which standards ensure protocol-level flow control and collision handling?


It adheres to IEEE 802.3x for full-duplex flow control and general IEEE 802.3 family behaviours for wired Ethernet.
