4I66 1
GENERAL
DESCRIPTION
The 4I66 is a stackable PC/104-plus card that combines a 100BaseT Ethernet MAC
with a 4 port switch. The 4I66 makes it easy to connect multiple embedded system cards
without the awkward power or mechanical problems with consumer type Ethernet switches.
The 4 Ethernet ports support autonegotiation allowing connections with half and full
duplex, 10 and 100 BaseT devices plus Auto-MDIX, eliminating the need for crossover
cables.
The Ethernet MAC is a National Semiconductor DP83816 which has drivers
available for most operating systems. The switch has sufficient bandwidth to support full
duplex wire speed connections on all ports.
