|Product CN-8301 - 10Base-FL 32-Bit EISA NIC with ST/SMA Connectors
The CodeNet-8301 is a 32 bit 10BASE-FL Ethernet network
adapters for the Extended Industry Standard Architecture
(EISA) bus. The board is a state-of-the-art bus master design
that uses the host system main memory directly When receiving or transmitting packet data or during buffer management,
the CodeNet-8301 requests the EISA bus from the host system.
Linked-list buffer management maximizes flexible memory
management and provides efficient data packet processing in
system memory by eliminating the need for intermediate copying of packets. The direct placement of data into system memory increases throughput while reducing CPU bus bandwidth
utilization. In fact, the high-speed interruptible DMA design of
the CodeNet-8341 typically consumes less than 5% of the CPU
bus bandwidth. EISA users can take full advantage of the inherent speed and power of i386, i486 and Pentium EISA computers in a fiber optic Ethernet network. For total software
compatibility the CodeNet-8301 supports both EISA (slot specific) and ISA compatible I/O addressing. The ISA mode should
only be used for software compatibility with ISA drivers.
CodeNet-8301 EISA adapter provides a high performance,
fiber optic link to an Ethernet network segment, based upon
the IEEE 10BASE-FL standard. which is backwards compatible
with the earlier Fiber Optic Inter Repeater Link (FOIRL) IEEE
standard. It is completely immune to electromagnetic noise
and no form of cable damage, like short circuits, ground faults,
reflections, or impedance mismatches, can disable the network. Fiber optic networks provide unparalleled security. Workstations can be up to 4 kilometers apart in both point to point
configurations. CodeNet-8301 10BASE-FUFOIRL cards are
compatible with other FOIRL or 10BASE-FL products and can
be used with other manufacturers' concentrators and repeaters.
Connects an EISA computer to any 10BASE-FL or FOIRL Ethernet network.
Bus Master with 32 bit wide data path.
Uses the 33 MB EISA bus transfer rate for maximum throughput.
Software support for popular network software systems, including: Novell NetWare 386, Microsoft LAN Manager (NDIS), Windows for Workgroup, Windows NT, Novell's UnixWare, Solaris 86, IBM's OS/2, SCO and Banyan Vines.
Computers can be more than 2 kilometers (1.2 miles) apart.
Fully compatible with the IEEE 802.3 10BASE-FL and FOIRL standards.
Link Integrity indicator and optical "idle" signal enhance data integrity, simplify problem resolution and allow simple measurements of transmitter power for testing cable links.
Multiple LED indicators for network trouble shooting.
Operates in all computers using the EISA bus.
CodeNet-8301 10BASE-Ft-/FOIRL adapters are compatible with other FOIRL or 10BASE-FL products and can be used with other manufacturers' concentrators and repeaters.
