1 Introduction
GE-2032R is a 32-bit PCI Gigabit Ethernet network interface card. It is designed for use on
computers with 32-bit PCI bus slots. GE-2032R runs in bus master mode, directly
sending/receiving Ethernet packets to/from memory.
The PCI bus master device is an intelligent device that can conduct processing independent of
the bus or other devices. It coordinates the sharing of the bus between the main processor and
target devices. Bus mastering allows a peripheral device to take control of the system bus
instead of only relying on the central processor.
GE-2032R complies with the IEEE 802.3u, IEEE 802.3, IEEE 802.3ab, IEEE802.3x Full
Duplex Flow Control and PCI Local Bus version 2.2, and transmit data to the network at
10/100/1000Mbps. GE-2032R can also operates in full-duplex mode to double the network
speed up to 20/200/2000Mbps when working with a Ethernet/Fast Ethernet/Gigabit Ethernet
Switch. It is the fastest Ethernet design of its kind. GE-2032R provides one RJ-45 port for
connection with 10BASE-T Ethernet/100BASE-TX/1000BASE-TX Gigabit Ethernet network,
and automatically senses the connection type.

Auto-Negotiation Support
GE-2032R is compliant with Nway auto-negotiation standard to automatically run at different
transmission speeds and modes that the connected hub supports. It detects the modes that are
currently running on the device on the other end, and announces its own ability to
automatically configure the highest performance mode possible for this connection.
If supported on both ends of the connection, auto-negotiation process is initiated to negotiate
for one of the following modes:
2000Mbps/FDX
1000Mbps/HDX
200 Mbps/FDX
100 Mbps/HDX
20 Mbps/FDX
10 Mbps/HDX
