The NI 8234 is a high-performance dual Gigabit Ethernet interface for PXI Express/CompactPCI Express based on the Intel 82571EB Gigabit Ethernet controller. It includes two Gigabit Ethernet ports within the single-slot PXI Express module, saving a slot in your PXI/CompactPCI system. By using 1000 Mbit/s Gigabit Ethernet, you gain a substantial performance increase over 100 Mbit/s Fast Ethernet while your system remains completely compatible with 10BASE-T and 100BASE-TX Fast Ethernet networks. The NI 8234 is compatible with Windows Vista/XP/Me/2000/98/NT and LabVIEW Real-Time.
