Product CN-8342B - CodeNet-3000-Compatible Passive 16-Bit ISA NIC with ST/SMA Connectors


Overview

    The CodeNet-8340B and 8342B are Passive Fiber Optic Ethernet Adapters for the Industry Standard Architecture (ISA) bus. These adapters operate in either 8-bit or 16-bit ISA slots or in any EISA slot. The board design allows the adapter to map its on-board RAM directly into the host systemís main memory (shared memory mode), or to use a Base I/O address for network adapter data transfer (NE2000+mode).
    The CodeNet-8340B/8342B ISA adapter provides a high performance, fiber optic link to an Ethernet network segment. The CodeNet PC/AT adapters are used in a high performance, high security, easy to maintain and install 10 Mbps Ethernet passive fiber optic segment. Workstation can be up to 1600 meters apart using low-cost CodeStar passive hub.
    CodeNet fiber optic Ethernet networks can be added to, and combined with existing copper cable based networks, thus allowing Ethernet networks to be expanded and converted to fiber optics anytime.


Features

Connects an IBM PC XT, AT, PS/2-25,30 and compatibles to a CodeNet fiber optic Ethernet LAN.
Dual-ported 16-Kbyte shared memory or Base I/O board access for exceptional performance No DMA channels required.
Software support for popular network operating systems including, Novell NetWare 386, Microsoft LAN Manager (NDIS), Windows for Workgroup, Windows NT, Novellís UnixWare, Solaris 86, IBM OS/2, SCO and Banyan Vines.
Operates in either 8-bit or 16-bit ISA slots or in any EISA slot.
Meets all applicable Ethernet and IEEE 802.3 signaling standards. 10 Mpbs, CSMA/CD.
Computers can be up to 1600 meters apart.
Multiple LED indicators for network troubleshooting.
Fiber Break function detects fiber breakage; enhances data integrity, when used with CodeStar passive hubs.
Switch selectable "Jabber" function protects system against unnecessary downtime.
SQE "Heartbeat" test may be defeated via switch selection, allowing unit to be used with IEEE-802.3 electronic repeaters.
