Physical and Electrical Characteristics
Devices are usually connected with a cable assembly consisting of a shielded 24-conductor cable
with both a plug and receptacle at each end. This design enables devices to be connected in either a
linear or a star configuration, or a combination of the two. See Figures C-2 and C-3.
