Safety Precautions

The following general safety precautions must be observed during all
phases of operation of this equipment. Failure to comply with these
precautions or with specific warnings elsewhere in this manual violates
safety standards of design, manufacture, and intended use of the
equipment. Interphase Corporation assumes no liability for the user’s
failure to comply with these requirements. As the user of the product,
you must observe all stated warnings and safety precautions in order to
safely operate the equipment in your environment.

Do Not Substitute Parts or Modify Equipment

Because of the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification of the
equipment. Contact your local Interphase representative for service and
repair to ensure that safety features are maintained.

Ground the Instrument

To minimize shock hazard, the equipment chassis and enclosure must be
connected to an electrical ground. The power cable must either be
plugged into an approved three-contact electrical outlet or used with a
three-contact to two-contact adapter, with the grounding wire (green)
firmly connected to an electrical ground (safety ground) at the power
outlet.

Do Not Operate in an Explosive Atmosphere

Do not operate the equipment in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment
constitutes a definite safety hazard.

Keep away from Live Circuits

Do not install or replace the component with power cables connected.
Under certain conditions, dangerous voltages may exist even with the
power cable removed. To avoid injuries, always disconnect power and
discharge circuits before touching them.

Telephone Lines Unsafe Voltages

As unsafe voltages (Telecommunication Network Voltages) exist on
ISDN lines, safety precautions must be taken to prevent contact with any
dangerous area of the system.

WARNING

■ The network cable(s) must remain disconnected from

the telecommunications system until the card has
been installed in the system.

■ The installation of the card in the host system must be

done in a way that ensures at least 2mm of air gap
between the Printed Circuit Board (PCB) card and any
other components in the host system, so that the
unsafe area remains located only on the card.

Telephone Wiring Warnings

Never install telephone wiring during a lightning storm. Never install
telephone jacks in wet locations unless the jack is specifically designed
for wet locations. Never touch non-isolated telephone wires or terminals
unless the telephone line has been disconnected at the network interface.
Any intervention on the card or in its proximity should be made with the
telephone connector unplugged.

Observe Dangerous Procedure Warnings

Warnings precede potentially dangerous procedures throughout this
manual. Instructions contained in the warnings must be followed. You
should also employ all other safety precautions which you deem
necessary for the operation of the equipment in your operating
environment.

WARNING

This equipment generates, uses, and can radiate
electromagnetic energy. It may cause or be susceptible to
electromagnetic interference (EMI) if not installed and
used in a cabinet with adequate EMI protection.

1Introduction

Adapter Overview

The Interphase iSPAN-Serial WAN adapter is a single-slot,
Peripheral Component Interconnect (PCI) add-on board for
PCI-based PCs, servers, and workstations. The adapter
provides a fast pathway to enterprise communication server
applications. It is a smart adapter that connects systems to a
Serial Line interface through a single, high-speed synchronous
communication port.

Figure 1-1. iSPAN-Serial WAN Adapter

iSPAN Serial WAN Adapter Users Guide 1

Hardware Overview

The modular adapter architecture includes a CPU motherboard
and a WAN daughtercard.

The CPU motherboard is powered by an IBM PowerPC
403GA 32-bit RISC processor, combined with a 32-bit/33­MHz PCI interface. The processor allows full support of
communication protocols, reducing host CPU usage.

The WAN daughtercard handles various communication
protocols at up to 2 megabits per second (Mbps). The
daughtercard supports the following serial interface types with
automatic recognition:

• V.24/V.28

• V.35

• X.21/V.11

NOTE

The iSPAN-Serial WAN adapter is referred to internally as
the 5535-1P-SR adapter. You might see both names used
in the Users Guide and the software dialog boxes to refer
to the adapter.

TM

Hardware Overview

Following are the standard hardware features of the adapter:

• Short PCI form factor (174.63 x 106.68 mm)

• PCI 2.1-compliant master/target bus interface

• Compliance to industry standards and specifications

(FCC part 15 Class A, IEC950)

• 32-bit RISC processor PowerPC

• 32-bit local bus at 33-MHz

2 Interphase Corporation

TM

403 GA @ 33 MHz

• 4 MB dual port DRAM memory and 128 KB Flash

EEPROM

• Synchronous serial line with DB25 female connector

(for serial WAN connection only)

• V24/V28, V35, or X21/V11 electrical interface

• Full plug-and-play installation

Software Overview

The software included with the adapter runs under Windows
NT 4.0 operating systems. It supports up to four iSPAN-Serial
WAN adapters installed in a system.

Two software packages are available: the NDIS package and
SNA Server Link Services package. The software is available
on two CD-ROMs, one for each package.

Software Packages

Chapter 1: Introduction

You can install the NDIS software package, the SNA Server
Link Services software package, or both software packages,
depending on your system needs. Both packages include the
Base driver.

Base Driver

The Base driver is the basic driver required to support the
adapter. It is delivered as a standard product with both the
NDIS driver and SNA Server Link Services.

The Base driver software files include the following utilities:

• The WAN Adapters Setup utility enables you to manage

adapter firmware and hardware.

iSPAN Serial WAN Adapter Users Guide 3

Software Overview

NDIS Driver

The NDIS driver emulates a LAN adapter. It enables
transportation and routing of TCP/IP and IPX/SPX protocols
over WAN serial lines, using X.25, PPP, or Frame Relay
protocols.

Along with the Base driver and NDIS driver, the NDIS
software package also includes the following utilities:

Using the NDIS Driver Setup utility, you can configure as
many as four NDIS logical adapters in a Windows NT system.
(A logical adapter represents a unique configuration of
connections to be handled by the NDIS driver.) As a result, the
NDIS driver can connect to four different IP and/or IPX
networks seamlessly. However, the driver needs to be installed
only once.

• The Synwatch utility enables you to track connections

and data traffic on the Serial port.

• The NDIS Driver Setup utility enables you to set up

logical adapters for NDIS communications.

• The NDIS Driver Log records NDIS driver events. It

enables you to view the events in the NDIS Driver Log
dialog box or the Windows NT Event Viewer.

Overview

The iSPAN-Serial WAN adapter can be connected as data
terminal equipment (DTE) to a communication device such as
a modem, data service unit (DSU), host computer, or another
serial adapter. The communication device enables connection
to the Public Switched Telephone Network (PSTN), a leased
line, an X.25 network, or a Frame Relay network. The iSPAN-
Serial WAN adapter can also be connected as data
communications equipment (DCE) to another serial adapter in
a back-to-back configuration.

Through its DB25 connector, the iSPAN-Serial WAN adapter
can be connected to any communication device that provides a
V.24, V.35, or V.11 interface. Each interface type requires a
specific cable. The adapter detects the cable connected to its
DB25 connector and automatically configures itself to the
appropriate interface.

This chapter provides the information about the following:

• iSPAN-Serial WAN adapter connector and DB25
pinout

• V.24 interface connection

• V.35 interface

• V.11 interface

• Back-to-back configuration

• Summary of steps to connect the adapter to the network

DB25 Connector

CAUTION

Incorrectly wired or installed cabling is the most common
cause of communications problems for wide area
networks. Interphase recommends that you work with a
qualified cable installer for assistance with your cabling
requirements.

DB25 Connector

The iSPAN-Serial WAN adapter connector uses a DB25
pinout. The DB25 pin signals vary according to the interface
selected. This external link is a Low Voltage Directory (LVD)
according to safety standard IEC950.

CAUTION

The adapter’s DB25 female connector is for serial WAN
connections only. Take care not to connect it to a parallel
device. (Parallel ports also use DB25 connectors.)
Connecting it to a parallel device may result in damage to
both the adapter and the parallel device.

4Installing the

NDIS Software Package

Overview

The NDIS driver enables the iSPAN-Serial WAN adapter to
emulate a LAN adapter. It supports the transportation of
TCP/IP and IPX/SPX protocols over WAN serial lines. The

NDIS driver enables the adapter to connect simultaneously to

TCP/IP and IPX/SPX LANs over dedicated leased lines or
through Frame Relay or X.25 networks. It is available for PPP,
X.25, and Frame Relay data protocols.

This chapter explains how to install the NDIS software on
Microsoft Windows NT 4.0 systems. Use this process to install
the Base driver, Base driver utilities, NDIS driver, and NDIS
driver utilities. This chapter also explains how to remove NDIS
and Base driver software, if required.

After installation, you can create up to four NDIS driver
configurations (referred to as logical adapters) on the server
for LAN connections. This multi-driver capability on the
server side enables remote users to connect to the server
through different networks simultaneously over serial lines.
NDIS driver connections provide remote access to services
typically available to LAN-connected users, such as file- and
print-sharing, database access, and messaging.

4

To install the NDIS software, follow these basic steps:

1. Verify that your system meets minimum requirements.

2. Install the Base driver and NDIS driver, with

accompanying software.

3. Set up WAN properties.

5 Setting Up the NDIS

Overview

You can create up to four NDIS driver configurations for
connecting the iSPAN-Serial WAN adapter to IP and/or IPX
networks. This capability allows the adapter to emulate a LAN
adapter and connect with up to four IP and IPX networks
simultaneously. The driver transports TCP/IP and IPX/SPX
protocols over the following types of connections:

• PPP, X.25, and Frame Relay point-to-point connections

• X.25 and Frame Relay point-to-multipoint connections

Each NDIS driver connection configuration is referred to as a
logical adapter. Logical adapters specify adapter properties,
network protocol properties, channels, and channel properties
to use for WAN network connections.

During the NDIS driver installation, one logical adapter is
automatically created and assigned a unique adapter identifier.
You can use the NDIS Driver Setup utility to change the
logical adapter’s default network and channel properties. In
addition, you can use the Windows NT Network Control Panel
to create up to three additional logical adapters, and then use
the NDIS Driver Setup utility to set up properties for the
logical adapters.
