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.
