system may already use addresses 0300H or 0320H
(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.
