    Configuration controls consist of two switches on the rear panel. These switches determine the power-up default paper size, hard-clip limits, and PI/P2 coordinate values. The switches are common to both HP-IB and RS·232·C interface options. Interface controls establish the conditions under which communication between the plotter and computer will occur.

    The Demonstration Plot/Confidence Test The plotter has a built-in demonstration plot that will run on any size paper. However, the plot is centered only on A-size paper and approxi· mately centered on A4-size paper. Therefore, if the plotter is set for B- or A3-size paper, the plotter will automatically switch to the corresponding smaller paper size before ru�ning the plot.

    If Your System Configuration Is Different From the One Listed . . . There are many variables in computer systems. Often substituting one piece of hardware or software for another can cause communication problems. Therefore, if you're going to make substitutions, be aware that these may affect the operation of the system or the communication verification program.
