nators. If the terminators do not measure 50 ohms
+/- 1%, replace the terminator. Measure the coaxial
cable with a 50-ohm terminator 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 network adapters support both popular cable
schemes used in Ethernet networks: 10Base-T
and 10Base-2. The following are the recommended
specifications for proper network cabling.

10Base-T networks use unshielded twisted-pair
cable and 8-pin RJ-45 modular connectors. Use
only 22-26 AWG 2- or 4-pair 100 ohm/ft UTP
(Catagory 3) or better cable. The cable must use
solid copper conductors and UL codes CM, CMR,
and CMP are required. The computer on the net-
work is connected via a star topology (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 conductor 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-connector must be
plugged directly into the network adapter (no cable
is allowed between the T-connector and the
adapter). No more than 30 connections are al-
lowed per segment and the maximum segment
length is 607' (185 m). The cable must be termi-
nated at each end by one 50-ohm terminator.
