Chapter Plotter Operation Introduction In this chapter you will learn about programming languages, the functions of each control and indicator, the plotter's coordinate system, and how to rotate the coordinate system. You will also learn how to load pens and paper and hQw to determine that the plotter is functional.

A program is an organized set of instructions that tells your computer and plotter to accomplish certain tasks. They consist of English words that are usually followed by numeric parameters. These statements describe their graphics plotting function and instruct the computer to send HP-GL instructions to the plotter.
One AGL statement often performs a task that would require several HP-GL instructions to perform. X-axis and the fifth positive grid line along the Yaxis. These coordinate values are used as parameters in HP-GL instructions to move the pen to any given point in the plotting area. Refer to Rotating the Coordinate System in this chapter. NOTE: The power-up default input window is coincident with the hard clip limits.
The size of the input window can be changed using the HP. GL instruction, lW, to programmatically limit the pen's motion. -. PI IDEFAULT) HAAO-CUP LIMITS (OEFAUL T) P2.

X and Y) or isotropic (equal in X and Y) and each axis can have a different n umber of user units.

VUB (user units), With this system, AGL programs can produce plots within any area defined by PI and P2 without modifications to the program. Refer to your HP computer documentation for the information you need to program in AGL.
Setting the Scaling Points The locations of scaling points PI and P2 can be changed manually from the front panel or programmatically with the Hp G L instruction I P. Refer to the Interfacing and Programming Manual for instructions on how to set the scaling points programmatically. Preparing Equal-Sized Plots Squeezing the Scaling Area P lIP2 When a frame is established within the plotting area, and then Pl!P2 PI is moved so that intersects the hardclip limits, a new frame is established at the point of intersection This feature is illus trated as follows: PlIP2 DETAIL A.

The rotate function can be manually invoked from the front panel, ENTER + FAST using the button combination, or programmatically, using the HPGL instruction, RO. The only difference is the rotated locations Ll (O, O OAIGIN) r - -.
The input window can be expanded to the hard clip limits and PI and P2 can be defaulted to the rotated default coor dinate values using the HP-GL instructions, IW and lP, without parameters. Whether invoked manually or programmatically, the physical size and location of the hard-clip limits are not affected by the rotate function. 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 RS232C interface options.
Interface controls establish the conditions under which communication between the plotter and computer will occur.

describe these procedures and include instructions for choosing the correct pen and medium combinations. Choosing the Correct Pen and Medium To obtain plots of the highest quality, it is important to use pens and media that matched to your application. Two types of liber-tip pens recommended: one for plotter paper and one for transparency film. Loading the Pens and the Carousel Loading the Plotting Medium The plotter is designed to be used with HP paper and pens.
Use of other paper may cause poor line quality. For best results, order papers listed under Accessories Available. To load paper, proceed as follows: Set the switches o n the rear panel to the approp.

Loading AI A4 Size Paper Loading BI A3 Size Paper Turning On the Power The plotter performs an initialization cycle when ac power is applied.
The initialization cycle sets all plotter functions to their default condi tions (conditions assumed by the plotter in the absence of an actual instruction). After power-up initialization is completed, the first pen select command will cause the carousel to be initialized. The pen select command can be invoked programmatically with an HpGL command or manually with pushbuttons. Carousel initialization consists of backing the carousel around to its stop before it is advanced the position that corresponds with the pen select command.

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 runing the plot. pt'ratiol1 G R A P H I C S I M P R O V E S C O M M U N I C A T I O N::;; t'1 ' SALES REVENUE D I STR I B U T I O N.'

Next, refer to either Chapter 9 or 10 in the HP 7475A Interfacing and Programming Manual (depending on which interface you're using) to get a better understanding of how information is sent and received by the plotter. 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.
