(Translated from German) The unit number of the plotter is 6. First of all you can address it like a printer: open 1,6 print#1, "hello!" CLOSE 1 The plotter draws then the letters (is again and again fascinating!). The meaning of the secondary address with the open instruction: 0: Pressures (default value, see above) 1: Plotten 2: Color select 3: Character size select 4: Indication rotation select 5: Line mode (e.g. dashed) select 6: Selection upper and lower case printing capability 7: Plotter RESET A plot program should keep several logical files with the different necessary secondary addresses open at the same time. The coordinate system: Horizontal (from on the left of to the right) the x axis is vertical, the y axis. The x axis goes from 0 to 479 (is 96mm). The y axis is programmable for values between -998 and +998. Plotting: print#1, "[instruction]",X,Y Values for [ instruction ]: H: To the absolute zero (0,0) induce (X and Y do not indicate here!) I: Specify relative zero point on current position (X and Y do not indicate here!) M: To the position X,Y induce, relative to the absolute zero, pin raised D: To the position X,Y induce, relative to the absolute zero, pin on the paper R: To the position X,Y induce, relative to the relative zero point, pin raised J: To the position X,Y induce, relative to the relative zero point, pin on the paper Example square: open 1,6,1 print#1, "M",50,0 print#1, "D",50,150 print#1, "D",200,150 print#1, "D",200,0 print#1, "D",50,0 CLOSE 1 Color selection: open 2,6,2 print#2, more [color number ] 0: Black 1: Blue 2: Green 3: Red In the manual it is said that the pins must be naturally inserted into the correct mounting plates; -) Character size: open 3,6,3 print # 3, [Big] 0: 80 indication/line 1: 40 indication/line (default) 2: 20 indication/line 3: 10 indication/line Indication rotation: open 4,6,4 print#4, [Rotation ] 0: Horizontal (default) 1: 90 degrees to the right turned Line type: open 5,6,5 print#5, [ line type ] 0: Pulled through (default) 1 to 15: Interrupted, the more largely the number, the longer the individual sections Character set: open 6,6,6 print#6, [ character set ] 0: Normally: Capital letter/shifted: Small letter 1: Normally: Small letter/shifted: Capital letter RESET: open 7,6,7 print#7 All values (e.g. character size, line type) are stopped to the default values and the memory of the plotter is cleared. I hope, been sufficient for the beginning. Otherwise I can only say: To try goes studying over. I am e.g. not safe me whether the y-values rise upward or downward. Here a contradiction is in the manual.
