PCN2000BT Supports both 10Base-2 and

10Base-T 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

must use solid copper conductors and UL codes

CM, CMR, and CMP are required. The computer

on the network 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 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 than 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 50-ohm terminators.
