1. INTRODUCTION
This chapter introduces some key features of the ZT 8995. It includes a product
definition, a list of product features, a functional block diagram, and a description of
each block. The ZT 97115 software setup and driver package for the ZT 8995 is also
covered. Carefully review this chapter to gain a basic understanding of the capabilities
of the ZT 8995. Unpacking information, as well as installation and setup instructions, are
in Chapter 2, "Getting Started."
ABOUT THE ZT 8995 INTERFACE
The following sections include a product definition for the ZT 8995 and a list of product
features.
Product Definition
The ZT 8995 is an Ethernet Interface for the STD 32 bus and for the STD bus. It
supports 10Base-T as well as Thin Ethernet (Cheapernet, 10BASE2) and Thick
Ethernet (10BASE5) cabling options. For cable configurations, review Appendix B,
"Network Components and Cabling". Additional ZT 8995 support includes extensive
software drivers for several popular network operating systems, a setup program, and
complete diagnostics.
The ZT 8995 conforms to the IEEE 802.3 and Ethernet standards for a 10 Mbps Carrier
Sense Multiple Access/Collision Detection (CSMA/CD) local area network. Local area
networks using twisted-pair, coax, and fiber optic media can be supported. Refer to
Appendix B, "Network Components and Cabling", for more information.
The ZT 8995 comes with a ROM socket and software drivers. Check the ZT 97115
disks for a complete list of supported drivers.
Software packages are also available for TCP/IP support. Department of Defense
TCP/IP software from FTP Software allows remote log-in, file transfer, terminal
emulation, electronic mail, and many other functions. TCP/IP is widely used and is
supported by over 150 vendors, allowing dissimilar computers and operating systems to
communicate.
Boot ROM capability for Novell NetWare V2.0A, V2.1 and later is supported by National
Semiconductor's boot ROM. When the boot ROM is installed on the ZT 8995, the disk
operating system is loaded from the network server. This diskless installation is ideal for
systems in harsh industrial environments where driver installation would normally
require rotating media.
The ZT 8995 is compatible with all Ziatech STD 32 and STD systems. A versatile setup
program allows you to configure the board for the desired I/O address, packet RAM
address, PROM socket address, and interrupt selection.

LAN Interface (DP83905)
The National Semiconductor DP83905 AT/LANTIC provides the interface between the
STD bus and the on-board Local Area Network (LAN) bus The DP83905 also provides
the network interface portion of the LAN bus.
The LAN Bus
The LAN bus consists of the packet RAM and Network Interface. LAN Interface
configuration values are programmed into an external EEPROM when the device is set
up. These values are automatically loaded into on-board registers when the board is
powered up.
Depending on the configuration, the DP83905, with some external help, decodes both
memory and I/O addresses when accessing the on-board PROM socket, RAM, or
Network Interface.
The Network Interface
The Network Interface provided by the DP83905 implements all Media Access Control
(MAC) layer functions for transmission and reception of Ethernet packets, in accordance
with both the IEEE 802.3 standard and pre-IEEE 802.3 standards.
It also contains an internal First In First Out (FIFO) buffer and arbitration logic to control
access to the packet RAM. The DP83905 includes:
•Support for physical, multicast, and broadcast address filtering
•Provision for three levels of loopback
•Implementation of buffer management
The DP83905 provides complete IEEE 802.3 protocol and electronics with the only
exception being the packet RAM.
Serial Interface (DP83905)
The National Semiconductor DP83905 also provides Manchester encoding, decoding,
and collision detection for the Serial Interface. The 83905 includes the following:
•10 Mbps encoding and decoding
•Loopback capability for diagnostics
•Isolation from Ethernet cable
The DP83905 interfaces the ZT 8995 to the Ethernet cable via an external Attachment
Unit Interface (AUI) drop cable, the on-board Transceiver Interface (8392), or twisted-
pair cabling.

1. Introduction
 9
Transceiver Interface (DP8392)
The National Semiconductor (or equivalent) DP8392 Transceiver Interface is used as a
coaxial cable driver/receiver for Thin Ethernet (Cheapernet) applications. The Thin
Ethernet cable can be connected directly to the ZT 8995 without using an external drop
(AUI) cable because the connector is isolated from the Serial Interface (8391) by an
isolation transformers and a DC to DC converter.
Packet RAM Buffer
The packet RAM buffer is 16 Kbytes in length and can be used by either the STD bus
processor or the Network Interface Controller (DP83905). This memory may be placed
on any 8-Kbyte memory address boundary. Compatibility with any memory move
instruction to the Network Interface results in a very efficient dual-ported packet buffer.
User PROM Socket
The ZT 8995 includes a PROM socket that can accommodate 32-, 64-. 128-, or 256-
Kbyte parts where only the top 32Kbyte block is accessible. The PROM can be mapped
into any 8, 16, 32, or 64Kbyte boundary beginning at one of eight software selectable
locations between 0C000h and 0D000h. The PROM can be accessed without
interfering with Ethernet packets being sent or received. You can use the setup program
AUTOSET8.EXE to configure the PROM socket address.
Interrupt Capability
Interrupts are supported by the ZT 8995. Interrupts are software selectable for
backplane signals INTRQ*, INTRQ1*, INTRQ2* (CNTL), INTRQ3*, INTRQ4* and
NMIRQ*. Frontplane interrupts can also be selected through software control across
FP3*, FP5*, FP6* and FP7*. Since IRQx is slot specific, it is always driven out onto the
backplane.
Diagnostic LEDs
The ZT 8995 has separate transmit, receive, and diagnostic LEDs. These LEDs provide
visual indication of network activity. Transmit activity is indicated by a red LED. Receive
activity is indicated by a green LED. A green LED is used to indicate a LINK and red
LEDs are used to indicate POLARITY problems as well as COLLISIONs.
ZT 97115 SOFTWARE DISK
The ZT 97115 software disk included with each ZT 8995 is supplied under license with
National Semiconductor. A variety of software drivers, a setup programs, and extensive
diagnostic programs are included. You can use any or all of the software drivers without
any additional cost or licensing.
