This manual contains interfacing and programming information for
the HP 7470 Plotter and all its interfacing options. The Option 001
plotter is equipped with the RS—232—C/CCITT V.24 Interface. The Option
002 plotter is interfaced through the Hewlett—PackardInterface Bus
(HP—IB) which conforms to ANSI/IEEE 488-1978 specifications. The
Option 003 plotter is equipped with the Hewlett-Packard Interface Loop
for personal computing devices. All interfaces use the Hewlett-Packard
Graphics Language (HP—GL) for control of plotter graphics capabilities.
Unless specifically noted, all information in this manual pertains to all
configurations.
NOTE: All information in this manual for Option 001 plotters applies
equally to RS—232—C and CCITT V.24 interfaces. For purposes of sim­
