adapters are a
family of third-generation Ethernet adapters. This family
includes the 32-bit bus master Peripheral Component
Interconnect (PCI)10 Mbps Ethernet network adapter, which
conforms to the PCI 2.1 specification. This guide contains
installation and diagnostic information about the following
PCI adapters:
■
3C590-COMBO (RJ-45, BNC, AUI connectors)
■
3C590-TPO (RJ-45 connector)
The two adapters are functionally identical; they differ only in
the layout of the components on each board and the type of
media supported on the backplates, as shown in Figure 1-1.
The name “3C590 PCI adapter” is used in this guide to refer
to both EtherLink III 10 Mbps PCI adapters unless otherwise
specified.
The bus master driver supplied with this adapter is
compatible with the Fast EtherLink 10/100BASE-T PCI
adapter. The bus master drivers shipped on the 3C59X
EtherDisk diskette are compatible with the 3C59X family of
adapters; they are not backward-compatible with the 3C5X9
family of EtherLink III adapters.
The 3C590 PCI adapter connects your PCI-compliant personal
computer to an Ethernet network wired with IEEE 802.3
standard 10BASE2 or 10BASE5 coaxial cable, or 10BASE-T
twisted-pair cable. The cable specification for each adapter
type is shown in Table 1-1.
