User can change hardware MAC address thousands of times

Supports Full Duplex flow control (IEEE 802.3x)

Fully compliant with IEEE 802.3, IEEE 802.3u

Hotplug support


Our lowest-priced ExpressCard adapter, the SD341 is a 10/100 Mbps Ethernet plug-and-play adapter. Firmware allows the user to program the physical MAC address thousands of times. Utilizes the latest chipset technology and provides easy installation. Automatic sensing connects to the network with a RJ-45 connector at the highest negotiable speed. With SD adapters, your computer will turn into a highly-configurable workstation or server.
