Fig.9 shows a typical network connection made with barrier strips. When used for termination
resistors, all five wires are attached to the barrier strip and the termination resistor, 120 ohms,
1/4 W connected between NET-H and NET-L. No connections are allowed to the other
terminals.

1.3 Network Cable
Two types of cable are used in the network, heavy cable and light cable. The selection of
cable type for various portions (including the drop cable) of the network depends on the
number of Network loads attached, the length of the network cables, and the location of the
specific cable in the network.
Heavy cable
The heavy cable is five-wire constructed with two individually twisted-shielded pairs
enclosed by an overall shield with a shield drain wire connecting all three shields.
Table 3 shows the wire colors of the heavy cable (10 mm diameter, MAX. 8 A).
