X-CAD 2000
==========
Thank you for purchasing X-CAD 2000. This file contains some general
notes and additional information that we were not able to include in
the manual, before its printing.
Making directory assignments manually
=====================================
If you wish to make the directory assignments, for X-CAD 2000,
manually, or you have an unusual system set up, you should add the
following to your StartupII or User-Startup file.
ASSIGN MENUS: <drive>XCAD2000/MENUS
ASSIGN XCAD20003DPMODS: <drive>XCAD2000/PMODS
ASSIGN XCAD20003DHANDLERS: <drive>XCAD2000/HANDLERS
ASSIGN DRAWINGS: <drive>XCAD2000/DRAWINGS
ASSIGN XSDATA: <drive>XCAD2000/XSDATA
ASSIGN XSFONTS: <drive>XCAD2000/XSFONTS
ASSIGN XSLOVLY: <drive>XCAD2000/XSLOVLY
ASSIGN XSMODS: <drive>XCAD2000/XSMODS
ASSIGN XSPOVLY: <drive>XCAD2000/XSPOVLY
ASSIGN SYMBOLS: <drive>XCAD2000/SYMBOLS
ASSIGN XCAD20003D: <drive>XCAD2000
Where <drive> is your hard-disk path name. e.g. "DH0:", "SYS:CAD/" or
"JH1:"
HPGL Plotter - Tricks & Tips
----------------------------
Most Hewlett Packard plotters use the serial interface. Unfortunately,
both Hewlett Packard plotters and Amigas sometimes have "unusual"
aspects in their serial communications. The following are various
tricks and tips that X-CAD users, with HPGL plotters, have passed onto
us, over the years. You will find that almost all Hewlett Packard
plotters, using a serial interface, will require some form of
initialisation before use with X-CAD. Naturally, this does not
normally apply to plotters using the parallel interface.
HP7475A Plotter
---------------
The HP7475A requires Xon/Xoff handshaking which is not used in its
default mode. In order to activate the handshaking, the following
escape sequence must be loaded into the plotter. This can be done by
sending a file to the plotter to initialise it. This file can be
created as follows:
COPY * to ram:HPXON
<ESC>.M;10;10;13:<RETURN>
<ESC>.N;19:<RETURN>
<ESC>.180;;17:<RETURN><CTRL\>
COPY ram:HPXON to s:HPXON
Note - The symbol <ESC> refers to the escape key. The symbol <RETURN>
refers to the return key. The symbol <CTRL\> refers to the keystroke
produced by holding down the CTRL key and hitting the (\) backslash
key.
Set your plotter for 9600 Baud. 8 data bits. 1 stop bit. No parity.
Run thew preferences tool and set the Amiga for custom/generic printer
and serial port output. Go into change serail to match the Amiga to
the plotter. Set handshaking to XON/XOFF and save the preferences. To
use the HPXON file in your Startup-Sequence add the following line
before the LOADWB command:
COPY s:HPXON to ser:
Initialisation using Amiga BASIC
--------------------------------
Another way of creating the necessary initialization file is to use
Amiga BASIC, or a similar program language. A program to do the same
as the above in Amiga BASIC would look like this:
REM ********************************
REM set up program for hpgl plotters
REM by Tim Gathercole - 8/6/92
REM ********************************
OPEN "RAM:HPSETUP" FOR OUTPUT AS #1
PRINT #1, CHR$(27);
PRINT #1,".(;";
PRINT #1,CHR$(27);
PRINT #1,".";
PRINT #1,"I81;;17:";
PRINT #1,CHR$(27);
PRINT #1,".N;19:"
CLOSE #1
The above has the advantage of being able to be re-written so that the
output file goes directly to the serial port. This can be done by
substituting "SER:" for "RAM:HPSETUP", in the program. This will
enable initialisation to be carried out by clicking on an icon. We
have found that most Hewlett Packard plotters will work correctly if
the above initialisation file is used. A compiled copy of both
versions of this program are in the utilities draw. However, for those
who prefer to write their own initiation file, further details, on
other plotters are provided below.
HP7448 Colour Pro Plotter
-------------------------
To use XON/XOFF with the above plotter you will have to create a small
initiation file. This file can be created as follows:
If your plotter has an add-on buffer use the following:
COPY * to ram:HPXON
<ESC>.P1:<ESC>.T1900;74:<ESC>.@1900<RETURN><CTRL\>
COPY ram:HPXON to s:HPXON
If your plotter does not have a buffer use the following:
COPY * to ram:HPXON
<ESC>.P1:<RETURN><CTRL\>
COPY ram:HPXON to s:HPXON
Note - The symbol <ESC> refers to the escape key. The symbol <RETURN>
refers to the return key. The symbol <CTRL\> refers to the keystroke
produced by holding down the CTRL key and hitting the (\) backslash
key.
Set your plotter for 9600 Baud. 8 data bits. 1 stop bit. No parity.
Run thew preferences tool and set the Amiga for custom/generic printer
and serial port output. Go into change serail to match the Amiga to
the plotter. Set handshaking to XON/XOFF and save the preferences. To
use the HPXON file in your Startup-Sequence add the following line
before the LOADWB command:
COPY s:HPXON to ser:
Pausing Plotters
----------------
If using a large data buffer between your Amiga and plotter, then by
creating a file containing the following HPGL commands and sending it
to the plotter before sending a second plot to the buffer, it will be
possible to store more than one drawing in the buffer.
SP;
EC;
PG;
EC1:
DE;
This series of commands should put the plotter into pause mode.
An Amiga BASIC program to create a file containing these commands,
would look like this:
REM ********************************
REM Pause program for hpgl plotters
REM by Tim Gathercole - 8/6/92
REM ********************************
OPEN "RAM:HPPAUSE" FOR OUTPUT AS #1
PRINT #1,"SP;EC;PG;EC1:DE;"
CLOSE #1
Again this output file can be sent directly to the serial port by
substituting "SER:" for "RAM:HPPAUSE", in the program.
HP7570A DraftPro
----------------
COPY * to ram:HPXON
<ESC>.M;10;10;13:<RETURN>
<ESC>.N;19:<RETURN>
<ESC>.I80;;17:<RETURN><CTRL\>
COPY ram:HPXON to s:HPXON
Note - The symbol <ESC> refers to the escape key. The symbol <RETURN>
refers to the return key. The symbol <CTRL\> refers to the keystroke
produced by holding down the CTRL key and hitting the (\) backslash
key.
Set your plotter for 9600 Baud. 8 data bits. 1 stop bit. No parity.
Run thew preferences tool and set the Amiga for custom/generic printer
and serial port output. Go into change serail to match the Amiga to
the plotter. Set handshaking to XON/XOFF and save the preferences. To
use the HPXON file in your Startup-Sequence add the following line
before the LOADWB command:
COPY s:HPXON to ser:

General Note
------------
The above pieces of information have been passed onto us by our users.
However, we cannot guarantee that they will work with all models of
Hewlett Packard plotter, or even up dated versions of the plotters
mentioned.
