Connecting the Interface
The Interface has a Centronics input and an RS422 output.
Centronics interface
The Centronics input of the Interface corresponds in its wiring
and signal characteristics to the input of a parallel printer. This
means that any normal printer cable permitting connection of
the data source with a Centronics printer can be used to
connect the Interface input to the data sender.
