Chapter 7 Setting The Interface Functions
This chapter describes how to connect your plotter to your computer.
Setting the Parallel Interface
§ To use the Centronics-compatible parallel interface, connect the plotter’s parallel connector to
the computer’s parallel port by cable.
§ Next, simply set the command mode plus the programmable resolution (when GP-GL command
is selected), or origin (when HP-GL command is selected),
For instructions on setting the functions, see Selecting the Command Mode and Setting the
Programmable Resolution.
CAUTION: The interface cable should be no longer than two meters.
NOTE: For the specifications of your plotter’s parallel interface, see Centronics-Compatible
Parallel Interface.
Setting the Serial Interface
§ To enable prompt compatibility with multiple software applications, you can register three
different groups of interface settings (RS-1, RS-2, and RS-3) in the plotter’s memory.
§ The desired group of RS-232C interface settings can be loaded from the control panel.
§ Incorrectly set interface conditions can cause the plotter to malfunction.
§ Be sure to set the plotter’s interface conditions to match those of your computer and the target
software application.
NOTE: For the specifications of your plotter’s serial interface, see RS-232C Serial Interface.
