PROTEL EASYTRAX version 2.06
(c) 1990 PROTEL TECHNOLOGY PTY LTD
Corrections/updates to Reference Manual
Installation notes:
(see Installation guide, beginning of page 11 of
the manual)
Disk organization
Easytrax is now delivered on four (rather than
three) 360K floppy disks. The disk called 'Drivers'
contains the current set of graphics drivers and
some of the Print/Plot drivers that did not fit on
the 'Plot' diskette.
Running Easytrax using two floppy disk drives
(supercedes procedures, described on page 14-15)
To start the program
Insert the Edit disk into drive A;
Insert the Library disk into drive B;
From the DOS prompt, type PATH B: then press
RETURN;
Type EASYEDIT then press RETURN to start the
program;
Once Easyedit is running you can remove the Edit
disk and use drive A for loading and saving your
workfiles. You can set the current path back to
drive A using the Files/Path command from within
Easyedit. Before you Quit Easyedit, you should
always re-set the File/Path command back to B: so
that the EASYEDIT.DFT file is saved in the same
volume as the EASYEDIT.OVR file. A description of
the .DFT file is provided on page 22 of the manual.
New graphics drivers
Since publication of the supplement have added new
drivers for the ATI VGA Wonder card and the
Paradise EGA480 card. The drivers are labelled
WOND800.DRV (800x600), WOND1024 (1024x768, Revision
5 cards only) and PEGA480 (640x480). There are a
number of cards that use the PEGA480 chipset.
Memory management
If memory is a problem, make sure that your
operating system is as 'bare' as possible - disable
network software and any TSRs (other than EMS/Mouse
drivers), etc. If memory is still a problem you may
need to consider additional EMS.
Repeat Placement with metric grids
If you are using the Repeat Placement
feature with some fractional metric
grids, the Offsets applied to repeats
can result in some unexpected
placements. This is because the metric
value must be rounded off to two decimal
places. For example the default 25 mil
imperial grid is equal to approx .625
mm, rounded-off to .63 mm by Autotrax.
If you attempt a repeat placement of a
row of pads, this rounding-off will
result in a cumulative error in spacing
as successive pads are placed. The
solution is to use even multiples of the
current snap grid as offsets OR to work
on a 'natural' grid pitch, i.e. .5 mm or
.6 mm OR to stay on the imperial grid,
rather than switching to metric prior to
repeat placement.
Easyplot - version 2.06
New Features
Roland 1000 Series plotters
A new plot driver has been added for these popular
plotter models (DXY 1100, 1200, 1300, etc).
It is called ROLAND RD-GL I.
This supersedes the information in the manual.
However, you should make sure that all
communications parameters are matched between the
program and the plotter.
Improved Path Handling in Easyplot
When you select the Setup/(Plotter, Printer or
PostScript)/Type, to choose a driver, a window
opens allowing you to specify the directory. The
default directory is now always the Easyplot home
directory.
Naming of output files:
The name of the current .PCB file is automatically
applied to output files, as when plotting to a
filename (rather than directly to a port).
PostScript printing
The following PostScript options are supported
by the current version of the Easyplot
program:
PS300A4 A4 sheet 300 dpi resolution
PS300A3 A3 sheet 300 dpi resolution
PS400A4 A4 sheet 400 dpi resolution
PS600A4 A4 sheet 600 dpi resolution
PS1200A4 A4 sheet 1200 dpi resolution
PS1200A3 A3 sheet 1200 dpi resolution
PSLINOA4 A4 sheet 1270 dpi Linotronic
PSLINOA3 A3 sheet 1270 dpi Linotronic
PS300B5 B5 sheet 300 dpi resolution
PS300LT US letter 300 dpi resolution
PS300LE US legal 300 dpi resolution
