Introduction 5
Introduction
The S5x family of Eiconcards are ISA cards that offer X.25
connectivity through one or two (depending on the the Eiconcard
model) high-speed ports (supporting V.24, V.35, or X.21 interfaces)
at speeds of up to 512 Kbps, and/or through an ISDN BRI port
(Eiconcard S51) at speeds of up to 128 kbps (over the “D” channel
or the “B” channels).
Note The Eiconcard S5x also supports protocols such as SDLC,
PPP, and Frame Relay.
All Eiconcards have been tested and found to comply with
the Electromagnetic compatibility, Safety and Network
connection regulations within the European Union, North
America, and other major territories. Read the regulatory
information on page 29 before installing and using your
adapter.
Hardware Features
The Eiconcard S5x features the following:
The High-Speed Interface (HSI) ports, support full duplex
communications over a V.24, V.35, or X.21 interface at speeds of up
to 512 Kbps per port (depending on the type of interface selected).
The ISDN BRI port supports transfer rates of up to 128 kbps (over
the “D” channel or the “B” channels).
Power Consumption
Warning: Check that power supply will not be overloaded. Maximum
power consumption of the board is stated above. The user should
check that the total power drawn by the host computer, the
Eiconcard S5x, and any other peripherals, does not exceed the
capability of the host power supply unit.

6 Installing the Eiconcard S5x
Installing the Eiconcard S5x
Follow the steps below to install the Eiconcard S5x. If you want the
Eiconcard S5x to be available to multiple users on a LAN, install it
in the PC that will function as a gateway for the LAN.
1 Prepare the PC
Turn off the PC and disconnect its power cable. Remove the cover
of the PC according to the instructions that came with it.
2 Prepare the Eiconcard
Prepare the Eiconcard S5x by selecting its I/O address and
communications interface.
a) Set the I/O address. The default I/O address is 380h. You only
need to change this setting if another card already installed in
the PC uses an I/O address in the range 380h to 387h. To
change the I/O address, follow the instructions in “Setting the
I/O Address”on page 22, then continue with Step 1(b) below.
b) Select the interface. The default setting enables the V.24 and
V.35 interfaces; to use these interfaces, continue with Step 2
below. To enable the X.21 interface instead, follow the
instructions in “Selecting an Interface”on page 24, then
continue with Step 3.
3 Install the Eiconcard S5x
a) Drain static electricity from your body by touching the metal
chassis (the unpainted metal at the back of your PC).
b) Locate a slot in your PC that has the same bus type as your
adapter.
If your PC has both ISA and PCI slots, the ISA slots are longer,
as shown.
Figure 1. Locating a PCI slot
PCI slots
metal plates
ISA slots

Installing the Eiconcard S5x 7
c) If there is a metal plate at the end of the slot, remove it and keep
the screw.
d) Firmly insert the adapter into the selected slot.
To avoid damaging your hardware, insert the adapter
only into a slot with the same bus type as the adapter.
Inserting the adapter into any other type of slot can
damage your adapter, your PC, or both.
Figure 2. Inserting the Eiconcard S5x.
e) Fasten the adapter with the screw (to ensure that the adapter
is properly secured and grounded to the PC’s chassis).
f) Replace the cover of your PC as described in your PC’s
manual.
g) Reconnect the power cable.
Note Although the Eiconcard S5x can be installed in any available
ISA expansion slot (unless the PC’s documentation specifies
otherwise), it is recommended that you install the card in a 16-bit
slot to take advantage of the higher IRQs and memory-address
locations available only through 16-bit slots.
4 Set the interrupt request level and memory segment address
These parameters are set using the Eicon Networks networking
software that you purchased with the Eiconcard S5x. Consult the
documentation included with the networking software for
instructions on how to configure the Eiconcard.
To determine the correct interrupt request level and memory
segment address values to use, follow the instructions in “Software
Configuration”on page 25, then continue with Step 5.

5 Test the Eiconcard S5x
The application software purchased with the Eiconcard S5x
contains a test program to verify the card’s integrity. Consult the
documentation supplied with this software for details.
6 Connect to the outside world
You are now ready to connect the Eiconcard S5x to the outside
world.
•To set up ISDN connections, consult “Making an ISDN Connec-
tion”on page 9.
•To set up an HSI connection, consult “Making an HSI Connec-
tion”on page 13.

Making an ISDN Connection 9
Making an ISDN Connection
Note Only the Eiconcard S51 supports ISDN connections.
After you have installed your Eiconcard S51, connect your ISDN
line.
•If you plan to use an Eicon Networks NT1, see “Connecting to
an Eicon Networks NT1,”below.
•If you plan to use a third party NT1 or if you are installing the
Eiconcard S51 outside of North America, see “Making an HSI
Connection”on page 13.
Connecting to an Eicon Networks NT1
To connect to an Eicon Networks NT1, plug one end of the Interface
Cable for ISDN NT1 into the DIN-4 port on the Eiconcard S51; plug
the other end into the DIN-4 port on the NT1. Figure 3 shows how
to make these connections.

10 Connecting to a Third Party NT1
Connecting to a Third Party NT1
To connect to a third party NT1, you must use the ISDN S/T Cable.
This cable includes interface circuitry which is not normally provided
by the third party NT1 (but which is provided by Eicon’s NT1).
Plug the ISDN S/T Cable into the DIN-4 port on the card as
illustrated in Figure 4.
•In North America and Australia, you may need to insert the
RJ-45 plug into the terminating resistor, and then insert the
terminating resistor into the S/T connector. The next section,
“Termination,”explains when to use the terminating resistor.
•In the rest of the world, insert the RJ-45 plug directly into the S/T
connector. Do not install the terminating resistor.
Plug the other end of the RJ-45 cable into the S/T port on your NT1.
Figure 4 shows how the ISDN S/T Cable, the terminating resistor
(when required), and the RJ-45 plug connect together.
Figure 4. Connecting the ISDN S/T Cable
The interface cable contains fully passive components and does not
affect the energy consumption or other specifications of the
Eiconcard. This passive interface is required to ensure regulatory
compliance and guarantee proper functionality.

Termination 11
Termination
This section applies to S/T interface users in Australia and North
America, and provides instructions to help set up termination
scenarios. Termination requirements vary according to: the number
of devices connected to the NT1; and the distance between the
devices and the NT1.
For users who require termination, the Eiconcard S51 S/T has been
shipped with a separate terminating resistor. For information on how
to install the terminating resistor, see “Installing a Terminating
Resistor”on page 12.
How do I determine the termination value?
Single ISDN Device
If the NT1 is connected to a single ISDN device (e.g.
Eiconcard S51), follow the instructions below.
75 meters or more
If the connection spans 75 meters (250 feet) or more, connect the
100 ohm terminating resistor included with the ISDN cable. Set the
NT1 to provide 100 ohms of resistance. Consult the manual
provided with the external NT1 for more detailed instructions.
Note Some NT1s do not support connections over 75 meters (250
feet). Check your user documentation to determine the distance
supported.
75 meters or less
If the connection spans less than 75 meters (250 feet), set the NT1
to 50 ohms of resistance, and do not connect the terminating
resistor. Consult the manual provided with the external NT1 for more
detailed instructions.

12 Termination
Multiple ISDN Devices
If the NT1 is connected to more than one ISDN device, follow the
procedures below.
75 meters or more
If the connection spans 75 meters (250 feet) or more, both end
devices on the ISDN bus must be set to 100 ohm termination. If the
Eiconcard is one of the end devices, connect the 100 ohm
terminating resistor included with the ISDN cable. Consult the
manuals provided with the other ISDN devices and NT1 for more
details.
Note Some NT1s do not support connections over 75 meters (250
feet). Check your user documentation to determine the distance
supported
75 meters or less
If the connection spans less than 75 meters (250 feet), set the NT1
to 50 ohms of resistance, and do not connect the terminating
resistor. Set the other ISDN devices to no termination. Consult the
manuals provided with the NT1 and other ISDN devices for more
detailed instructions.
Installing a Terminating Resistor
The terminating resistor is installed by inserting the RJ-45 end of
the ISDN cable into the terminating resistor, and then inserting the
terminating resistor into the ISDN S/T cable (see, “Connecting the
ISDN S/T Cable”on page 10.

Making an HSI Connection 13
Making an HSI Connection
The Eiconcard S5x can connect as a DTE to devices such as Data
Service Units (DSUs) which support one of the following interfaces:
V.24, V.35, or X.21. It can also connect directly to a host computer,
or back-to-back to another Eiconcard. Each HSI port is configured
independently
Table 1 lists the most common connections supported by the HSI
port, and specifies the part number of the required Eicon Networks
cable. For information on making your own cables, see “Interface
Specifications”on page 14.
Table 1. Standard Interface Cables
When you make connections through a null-modem cable—for
example, to a DTE or to the HSI port on another Eiconcard—one
card must be set to internal clocking, and the other to external
clocking.
Consult the documentation which came with your networking
software for more information about port configuration.

Cable Construction Information 15
Cable Construction Information
If you plan to construct your own HSI cables, be sure to observe the
guidelines given below.
Wire Gauge, Grounding, and Pairing
•Use 26 or 24 AWG wire. Contacts should be 30 microinch gold
flash.
•The cable must be grounded both by a drain wire connected to
pin 1 on both sides (pin A on the type M connector) and by the
braid. Both the drain wire and the braid must be connected to
the connector case and shell at each end of the cable. The braid
must be connected through its full circumference.
•Unused wires must be connected to the cable shield at one end.
•Use an anti-EMI shield.
•Important. Wires identified by a rectangle under the heading
“Twisted pair”must be installed as a twisted pair. If you do not
install twisted pairs correctly, the cable will not work.
Type of Connectors
The HSI port accepts a 26-pin, 3-row male connector. The types of
connectors used on the interface-specific end of the cable are as
follows:
