Introduction 5
Introduction
The Eiconcard C2x is an ISA Plug-and-Play (PnP) card that offers
X.25 connectivity through a V.24 serial port at speeds of up to 64
Kbps, and/or through an ISDN BRI port (Eiconcard C21) at speeds
of up to 128 Kbps (over the “D” channel or the “B” channels). The
Eiconcard C2x is typically used for stand-alone or remote LAN
gateways.
Note The Eiconcard C2x 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 17 before installing and using your
adapter.
Hardware Features
The Eiconcard C2x features the following:
The V.24 port, supports full duplex communications over a V.24
interface at speeds of up to 64 Kbps.
The ISDN BRI port supports transfer rates of up to 128 kbps (over
the “D” channel or the “B” channels).
About this Manual
This guide describes how to install the Eiconcard C2x in any
computer with an IBM PC-compatible ISA bus. It covers the
following topics:
• Installing the card and connecting cables.
• Interpreting the status lights on the card.
For instructions on setting up communications protocols and using
applications, consult the documentation provided with your
networking software.

6 Installing the Eiconcard C2x
Installing the Eiconcard C2x
Follow the steps below to install the Eiconcard C2x. If you want the
Eiconcard C2x 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 Install the Eiconcard C2x
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
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 C2x.
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 C2x 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.
3 Test the Eiconcard C2x
The application software purchased with the Eiconcard C2x
contains a test program to verify the card’s integrity. Consult the
documentation supplied with this software for details.
4 Configure the Eiconcard C2x
Before you can use the Eiconcard C2x, you must configure it to work
with your communications software. The documentation which
came with this software contains complete instructions on how to
configure the card.
For information on the LED functionality, see “LED Functionality”
on page 15.
5 Connect to the outside world
You are now ready to connect the Eiconcard C2x to the outside world.
• To set up ISDN connections, consult “Making an ISDN Connec-
tion” on page 8.
• To set up a V.24 connection, consult “Making a V.24 Connection”
on page 13.

8 Making an ISDN Connection
Making an ISDN Connection
Note Only the Eiconcard C21 supports ISDN connections.
After you have installed your Eiconcard C21, connect your ISDN
line.
In Europe and most countries worldwide
In Europe as well as most countries outside of North America and
Japan, your Eiconcard C21 adapter can be connected directly to
your ISDN line using the included cable.
Figure 3. Connecting the ISDN cable.
1Take the cable included with the Eiconcard C21.
2Plug one end into the Eiconcard C21.
3Plug the other end into the ISDN wall jack.
In North America and Others
In North America and some other countries (check with your ISDN
provider), you need an NT1 (network terminating device) to connect
your ISDN line. However, depending on your Eiconcard C21
interface, the NT1 might be integrated into the adapter. Follow the
instructions for your adapter (with U-interface or S/T-interface).
Note North American and Australian Eiconcard C21 S/T users may
need to adjust the Eiconcard C21 termination. Refer to the section
“Termination” on page 11, for more information.

Eiconcard C21 U-interface:
If your Eiconcard C21 has a U-interface, the NT1 is integrated into
the adapter, and you do not need a separate NT1.

2Plug the RJ-45 end into the Eiconcard C21.
3Plug the RJ-11 end into the ISDN wall jack.
Note In North America, many ISDN wall jacks (with a U-interface)
are RJ-11. However, if your ISDN wall jack is RJ-45, you can still
plug the RJ-11 end of the cable into your RJ-45 ISDN wall jack
(there will be some space on both sides of the plug).

Eiconcard C21 S/T-interface:
If your Eiconcard C21 has an S/T-interface, you need a separate NT1.
Note You can order an NT1 from Eicon Networks or from another
supplier.

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 C21 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 C21), 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
If termination is required and your Eiconcard C21 does not have the
built in termination switch, you should have been supplied with a 100
ohm 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 wall jack.

Making a V.24 Connection 13
Making a V.24 Connection
The Eiconcard C21 can make V.24 connections using standard V.24
cables.
