Using The Plotter In A Terminal-Only Environment - HP 7470A Interfacing And Programming Manual

Using the Plotter in a Terminal-only Environment
Installation
The 7470 plotter can be directly connected to a terminal if a specially
constructed, user-supplied cable that swaps lines 2 and 3 is used. While
there is no computer in this configuration, the terminal usually has
some "intelligence." When the terminal and plotter are connected using
this special cable, the terminal may be used to send instructions to the
plotter. A diagram of the terminal-only environment and a picture
showing the rear-panel connection follow.
