Section One - Introduction  
Maxtech’s NX-16 Series network adapt-  
ers are high performance, software configurable  
Ethernet network adapters. Software configura-  
tion provides many advantages over conventional  
hardware configured products, including ease of  
installation, auto-configuration, and convenient  
re-configuration. There is no need to set numerous  
and unfamiliar jumpers when installing or re-  
configuring the network card. The included setup  
program can either automatically select valid I/O  
and IRQ addresses when a conflict is detected, or  
custom-configure the adapter using parameters of  
your choice.  
The NX-16 Series network adapter cards  
are Industry Standard Architecture (ISA) compat-  
ibleproductsandcanbeusedinanyIBMPC/XT/AT  
or other fully compatible computer. The adapters are  
NE-2000 compatible and include a 16KB RAM  
buffer for faster networktransmissionandreception.

2.3 Card Configuration  
The following configuration options are  
available in the SETUP program:  
• Auto Configuration  
• Set Configuration  
The Auto Configuration option allows  
automatic configuration when a Maxtech NX-16  
Series network adapter is installed in the PC. This  
option will select valid I/O and IRQ addresses  
when a conflict is detected with other adapter cards  
installed in your PC.  
The Set Configuration option allows  
selection of operating parameters such as I/O Base  
Address, IRQ selection, Transceiver, and Boot  
ROM Address.  
Thedefaultconfigurationparametersare:

Running the SETUP program  
1. Insert the installation diskette into your  
drive, log on to that drive, and run the  
SETUPprograminthe\DIAGsubdirectory.  
Assuming that your have inserted the dis-  
kette in drive A, you would type the follow-  
ing at the DOS C: drive prompt:  
A: [ENTER]  
\DIAG\SETUP [ENTER]  
2. Select the network adapter that you would  
like to configure (if you have more than one  
adapter installed). Otherwise press the En-  
ter key if you have only one adapter in-  
stalled.  
3. A) Select the Auto Configuration option if  
you would like the program to configure  
your network card for you (if you have two  
or more NX-16 Series adapters installed in  
your PC, you will need to install and config-  
ure the adapters one at a time).  
or  
B) Select the Set Configuration option if  
youwouldliketocustomizetheI/Oaddress,  
IRQ line, or other operating parameters.  
Use the UP or DOWN arrow keys to select  
a value from a list of valid values displayed  
in a selection window. Press F3 to save the  
new setting.  
If the Auto Configuration option does not  
properly configure your adapter then use  
the Set Configuration option to set-up  
your adapter.

2.4 Testing The Adapter  
The SETUP program provides an option  
in its main menu for adapter diagnostics. One or  
more PCs on the network can run the test simulta-  
neously. The Test Adapter option 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 using this option.  
If any test fails, the program notifies you of the  
error and suggests actions to correct the problem.  
Follow the on-screen prompt to start or stop the  
Network Function Test.  
The following suite of tests are available  
through the Test Adapter option:  
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-  
mit/receive tests on the network link  
7. Interrupt Test: Checks Interrupt Line  
8. Network Function: Performs network  
packet transmit/receive tests  
2.5 Boot ROM Installation (optional)  
An empty ROM socket is provided on the  
adapter to accept an optional Remote Boot ROM  
(available from your dealer). The Boot ROM al-  
lows the PC to load the Operating System over the  
network for diskless applications.  
1. Insert the Boot ROM into the socket. Make  
6
 
sure that the notch on the ROM matches  
that on the socket (refer to Figure 2).  
Figure 2  
Align ROM  
and socket  
notches  
2. Configure the adapter using the SETUP  
program to enable the Boot ROM function  
by selecting the appropriate address from  
the Boot ROM Base Address option. Refer  
to Section 2.3 for more information on  
running the SETUP program.  
3. Follow the Remote Boot Workstation in-  
stallation procedure given in your network  
operating system manual (i.e. create a Boot  
Image on the server for Novell networks, or  
start remote booting services on LAN Man-  
ager networks, etc.).  
Section Three - Driver Installation  
Thenetworkoperatingsystem(i.e.Novell,  
LAN Manager, etc.) that you are using requires a  
driver to access the network adapter card. The  
Maxtech NX-16 Series adapters are NE-2000  
compatible and use the NE-2000 driver supplied  
with your network operating system. Drivers for  
most popular network operating systems are also  
included on the installation diskette in separate  
subdirectories. Each directory also includes a  
7
 
README.TXT file describing the driver. Refer to  
the RELEASE.TXT file on the installation diskette  
for more information on the available drivers.  
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  
after reading the following information, contact  
your dealer or vendor for assistance.  
Most adapter failure after installation is  
caused by A) I/O base address and IRQ Line  
conflict, or B) Cable problems.  
4.1 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 system may already use addresses 0300H or  
0320H (example: sound/audio card). Vary the  
settings on your network adapter by running  
SETUP again to eliminate the conflict. Running  
the diagnostic in SETUP will also help to detect  
configuration conflicts.

4.2 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 NX-16 Series network  
adapters support both popular cable schemes used  
in Ethernet networks:  
NX-16T - Supports 10Base-T networks.  
NX-16B - Supports 10Base-2 networks.  
NX-16BT - Supports both 10Base-T and 10Base-  
2 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  
9
 
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 uses 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 then 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 one 50-ohm terminator.
