PCMCIA Ethernet adapter will not allow
incorrect insertion. Insert the Ethernet
adapter gently but firmly into the slot until
it stops.
4. Insert the 10Base-T (or 10Base-2/10Base-
T) Media Coupler into the adapter. One end
of this coupler has a special spring-action
connector which fits into the PCMCIA
Ethernet adapter. To insert or remove the
spring-action connector, squeeze the lock-
ing arms on either side of the connector.
This connector is keyed and will not allow
incorrect insertion (refer to Figure 1-A or 1-
B).
5. Attach the network cable to your Media
Coupler. Use either UTP cable for 10Base-
Tnetworksorthincoaxialcablefor10Base-
2 networks. Refer to Section Five for de-
tailed cable information.
2.3 PCMCIA Device Driver Installation
Before any network driver or software is
loaded, you must first install a PCMCIA device
driver for the PCMCIA Ethernet adapter. Your
computer should already provide support for
PCMCIA products via special programs on the
utility diskette shipped with the COMPUTER
(known as Socket Service/Card Service). Execute
the Socket/Card Service programs according to
specific instructions supplied by the computer’s
manual. If your computer DOES NOT provide
support for PCMCIA products, contact your com-
puter vendor for information on availability of
Socket/Card Services. You will now install the
PCMCIA Ethernet device driver from the supplied
4
driver diskette. Consult the README file on the
driver diskette for specific instructions on how to
install the driver.
Note: If you are unable to obtain Socket
Service and Card Service from your computer
manufacturer, you may still be able to use the
PCMCIA Ethernet adapter with the included
PCMCIA device driver. Consult the README
file to determine if your computer is supported in
this configuration and for instructions on how to
proceed.
The PCMCIA Ethernet adapter uses the
memory region D400-D7FF to read Ethernet ID
and other information from on-board flash ROM.
Please be certain that this memory region is ex-
cluded from usage by other programs, including
memory managers. Memory management is a
component of Microsoft DOS and Windows and is
used extensively. If you are running a Microsoft
memory manager, make sure that the x=D400-
D7FF
parameter
appears
in
the
Device=EMM386.EXE entry in your
CONFIG.SYS.
Example:
DEVICE=EMM386.EXE NOEMS X=D400-D7FF
Since Socket Service and Card Service
generally require 4-8 KB of contiguous space in
the Upper Memory Blocks, we recommend using
the following entry:
Example:
DEVICE=EMM386.EXE NOEMS X=D000-DFFF
If
you
do
not
have
a
DEVICE=EMM386.EXE entry in your
5
CONFIG.SYS, add the above example to your
CONFIG.SYS by using a text editor.
Consult your memory manager's manual
for the appropriate exclusion parameter if you are
not using the Microsoft memory manager.
The PCMCIA device driver allows selec-
tion of operating parameters such as I/O Base
Address and IRQ selection. The recommended
adapter configuration parameters are:
I/O Address: 0300H
IRQ Line: 5
2.4 Testing The Adapter
It is not necessary to test the PCMCIA
Ethernet adapter. However, if you encounter prob-
lems with your network connection, run the diag-
nostic program provided on the driver diskette.
The diagnostic program runs several tests and the
results are indicated by either PASS or FAIL.
Make sure that the network cable is attached (and
properly terminated if using a BNC connection) to
the adapter when running this program. If any test
fails, the program notifies you of the error and
suggestsactionstocorrecttheproblem.Followthe
on-screen prompt to start or stop the Network
Function Test.
The following suite of tests are available
through the diagnostic program:
1. Configuration Test: Identifies the host PC
2. I/O Test: Tests configured I/O port
3. ID Test: Verifies the adapter’s node ID
4. RAM Test: Checks on-board RAM
5. Internal Loop back Test: Performs trans-
mit/receive tests within the controller
6. External Loop back Test: Performs trans-
6
mit/receive tests on the network link
7. Interrupt Test: Checks Interrupt Line
8. Network Function: Performs network
packet transmit/receive tests
Section Three - Network Driver
Installation
The supplied network drivers allow the
Ethernet adapter to work with various network
operatingsystems(i.e.,NovellNetware, Microsoft
LAN Manager, etc.). Drivers for most popular
network operating systems are included in the
driver diskette in separate subdirectories. Each
directory also includes a README.TXT file de-
scribing the driver. Refer to the RELEASE.TXT
file on the driver diskette for more information on
the available drivers.
Note: Consult the README file in the
ROOT directory of the driver diskette for addi-
tional information on installation of these net-
work drivers for your particular network operat-
ing system.
Section Four - Troubleshooting
This section describes some of the com-
mon problems you may encounter while using
your network adapter. When troubleshooting, you
should make sure that the network you are con-
nected to is functioning. If you suspect that the
adapter is malfunctioning, replace it with another
adapter which is known to function properly. Also
try the adapter in another computer. This can
indicate whether the adapter or computer causes
the problem. If you can not resolve your difficulty
7
after reading the following information, contact
your dealer or vendor for assistance.
Most adapter failure after installation is
causedby:A)IncorrectlyinstalledPCMCIAdriver,
B)Not excluding memory address D400-D7FF
when using a memory manager, C)I/O base ad-
dress and IRQ Line conflict, or D)Cable problems.
4.1 Incorrectly Installed PCMCIA Driver
The included PCMCIA driver runs as a
Card Service Client and should only be loaded
after the Socket and Card Services are loaded. Be
certain that the CONFIG.SYS file contains DE-
VICE= entries in this order.
4.2 Not Excluding Memory Address D400-
D7FF
The PCMCIA Ethernet adapter uses the
memory region D400-D7FF to read Ethernet ID
andotherinformationfromon-boardflashROM.
This memory region must be excluded from
usage by other programs, including memory
managers. If you are running Microsoft's memory
manager, make sure that the x=D400-D7FF or
x=D000-DFFF parameter appears in the
Device=EMM386.EXE entry in your
CONFIG.SYS. Refer to Section 2.3 for detailed
information.
4.3 I/O Base Address and IRQ Conflict
Make sure that the I/O address and IRQ
used by the adapter is not already in use by
another device in your PC. If your PC has built-in
serial ports then you will not be able to use IRQ 4
(COM1) or IRQ 3 (COM2). Other adapters in your
8
systemmayalreadyuseaddresses0300Hor0320H
(example: sound/audio card). Vary the settings on
your network adapter by running the PCMCIA
device driver with different I/O port addresses and
IRQs to eliminate the conflict. Running the diag-
nostic program will also help to detect configura-
tion conflicts.
4.4 Cable Problems
A) Observe the green Link Status LED if
you are using a 10Base-T network. Turn on the
computer. Connect the network cable and observe
the green LINK LED. If the LED is ON, then the
system is connected. Otherwise check for a proper
RJ-45 connection.
B) Make sure the coaxial cable is prop-
erly terminated if you are using a 10Base-2
network. Each end of a coaxial segment must be
properly terminated with a 50-ohm terminator.
You may use a simple ohm meter to determine if
the cable is functioning properly. Disconnect all
nodes on the network and measure the resistance
of the terminators. If the terminators do not mea-
sure 50 ohms +/- 1%, replace the terminator.
Measure the coaxial cable with a 50-ohm termina-
tor attached to one end. The total resistance of the
cable plus the terminator should be no more than
a few ohms more than the terminator alone.
Section Five - Cable Information
The Maxtech PCN2000 Series PCMCIA
Ethernet adapters support both popular cable
schemes used in Ethernet networks:
PCN2000T
Supports 10Base-T network.
9
PCN2000BT Supports both 10Base-2 and
10Base-T networks.
10Base-T networks use unshielded
twisted-pair cable and 8-pin RJ-45 modular con-
nectors. Use only 22-26 AWG 2-pair 100 ohm/ft.
UTP with two to three twists per foot. The cable
must use solid copper conductors and UL codes
CM, CMR, and CMP are required. The computer
onthenetworkisconnectedviaastartopology(i.e.
each node is connected to a HUB, not to each
other). Maximum cable length is 300' (100 m).
10Base-2 networks use a single conduc-
tor coaxial cable and BNC connectors. Use only
RG-58A/U or RG-58C/U coaxial cables. Each
network node is connected to the coaxial cable via
a T-connector (included). The minimum distance
between T-connectors is 1.6' (0.5m). The T-con-
nector must be plugged directly into the network
adapter (no cable is allowed between the T-con-
nector and the adapter). No more than 30 connec-
tions are allowed per segment and the maximum
segment length is 607' (185 m). The cable must be
terminated at each end by 50-ohm terminators.
