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.
