3.1.8.1 Direct Coupling
Direct Coupling connects the subsystem/terminal device
directly to the bus and can only be used in connections
under one foot in length.
Since a Direct Coupled stub provides only limited isolation
in the event of a device (subsystem or terminal) short,
Transformer Coupling is normally the recommended
method of connecting to the bus.
