Dip-Switches

Switch Function Description
S1 Parity Controls whether parity gerneration and checking will occure for data transmission. If set to “0” no parity generation or checking will occure. If set to “1” parity generation and checking will be odd or even depending uppon the setting of the S2 switch.
S2 Odd/Even Set parity to odd or even. “1” establishes odd parity; “0” establishes even parity.
D/Y Programmed Position D is used if plotter is directly connected to a computer. The plotter will respond to all HP-GL and escape sequence instruction, expect the ESC.) or ESC.Z plotter “off” instructions.
    Position Y is used when the plotter is connected between a terminal and a computer. In this state the plotter will pass informatio between the terminal and computer; but only respond to a plotter “on”, ESC.( or ESC.Y instruction. After receipt of a plotter “on” instruction, the plotter will respond to all HP-GL and escape sequence instructions.
US/MET US or Metric This switch in compination with A3/A4 switch select one of four paper sizes whith the appropriate sized hard-clip limits and default P1/P2 coordinate values. The positions of the US/MET and A3/A4 switches are checked only when power is first turned on, or when a front-panel reset is invoked using ENTER+VIEW pushbuttons.
A3/A4 Paper Size This switch is used in combination with US/MET switch to select the default paper size. After power is turned on, paper size can be toggled between A and B or A4 and A3 size using the front-panel ENTER+SIZE push button.
B1-B4 Baud Rate These four switches are used to select a baude rate which correspond with your computer’s data transmission rate. When set to “external”, the baud rate is generated by an external clock connection pin 17 of the RS-232-C/CCITT V.24 connector.

Software Setup

Linux

Setup the serialport with the following command where XXX is the name of your device e.g. USB0.

# stty 9600 parodd parenb crtscts -F /dev/ttyXXX

You can then plot any *.hpgl, *.hgl or *.plt file with

# cat world.plt > /dev/ttyXXX
