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
