Product CN-8302 - CodeNet-3000-compatible Passive 32-Bit EISA NIC with ST/SMA Connectors

Overview

    The CodeNet-8300/8302 are 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-8300/8302 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-8300/8302 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-8300/8302 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-8300/8302 EISA adapter provides a high performance, fiber optic link to an Ethernet network segment, based upon the IEEE 10BASE FP standard for Passive Fiber Optic Ethernet, 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 net- work. Fiber optic networks provide unparalleled security Workstations can be up to 1000 meters apart using a low cost and "fool proof" CodeStar passive hub in the center of the passive segment.
   CodeNet fiber optic Ethernet networks can be added to, and combined with existing 10BASE-T and coaxial network sections, allowing new network segments to be added as fiber networks for performance, reliability and return on investment.
