HP 7475A Plotter w/ BS2
Archiver
Posts: 46,084
I wish to interface my BS2 with my HP 7475A Plotter. I have
connected my BS2's pin 0 to the serial in line of the plotter. I am
trying to send Text to the plotter at 9600 Baud, No parity, 8 Stop
bits. So far, All I can do is get the Error light on the plotter to
flash. heh. So I gurss it is recieving the data. I just don't know
how to program the Plotter to plot simple strings of text. Can
anybody help me out with programming this thing? Thanks.

Some code snippets:
IN INITIALIZE
PA Plot Absolute, Moves are with reference to home (0,0)
PD Pen (Z) Down, If already down, no movement
PR Plot Relative, Moves are with reference to current position
PU Pen (Z) Up, Move to UpPos position
SP Select Pen, May force a Pause.
EXAMPLES
(LOOKS SOMETHING LIKE THIS)
IN; SP 1;PU 0 0;PD 100 100;PD 100 50;PU 0 0;
(DOES THIS)
INITIALIZE
SELECT PEN 1
PEN UP MOVE TO 0 0
PEN DOWN MOVE TO 100 100
PEN DOWN MOVE TO 100 50
PEN UP MOVE TO 0 0

You cannot simply send a text string to the plotter. You must send commands
to the plotter in the HPGL language. This is HPs plotter language. There are
books that describe the HPGL. Do a search and find them on the web.
Hope this helps

Manual" which also comes with the plotter is part number 07475-90002.

don't have the manuals. Call HP; the manuals are pretty "reasonable" in
price, from what I remember. They explain how to control it. You just send
ASCII to it over a serial port. You do have the RS-232 version of the
plotter, right? If you have the HPIB version, your problem is more difficult.
