Universal Laser Systems M-360 Safety, Installation, Operation, And Basic Maintenance Manual page 21

MEMORY CONTROL
The laser system is equipped with 16 Megabytes standard and is expandable to 32 Megabytes to store
downloaded files while the system is powered ON. Eventually the memory will fill up with files that will
need to be deleted to free up space for more files. To delete one file at a time, display the desired file by
using PREVIOUS FILE or NEXT FILE buttons. Use the UP or DOWN arrow button to position the cursor
on the DELETE THE FILE menu item and then press SELECT. Select a CANCEL or YES response to
the ARE YOU SURE question. To completely clear out all files at the same time, position the cursor on
the DELETE ALL FILES option and press SELECT.
DOS POWER SETTINGS
Use this menu selection ONLY if you are printing from a DOS based CAD program that can output pure
HPGL. Here you can assign POWER, SPEED, and PPI to the pen numbers as if you were assigning pen
colors to a flatbed plotter. Since using this menu feature has many limitations, we suggest using only
Windows based software.
PREFERENCES
Options, diagnostic, and maintenance features are found within this menu selection. If you change
anything within this menu, and would like those changes to remain, next time you power ON the system,
make sure you ESCAPE back to the MAIN menu before turning off the laser
OPTIONS
Select this menu to access optional features that your system may have.
ONE FILE MEMORY
Pressing SELECT will toggle the setting ON (ONE FILE MEMORY enabled) and OFF
(MULTIPLE FILE MEMORY enabled). The purpose of ONE FILE MEMORY is to store
only one file in the laser system's memory. Successive file downloads erase the previous
file in memory, avoiding the need to constantly clear the memory or press the NEXT FILE
button. This feature is useful if you only run files only once. However, if you want to
repeat the file that is memory, you may do so as many times as you want providing that
you do not download a new file or power the system off. While this mode is ON, we
recommend that you do not print to the laser system until it has finished processing the
current file, otherwise you may get a "printer timeout" error displayed on your computer.
This is because that while the laser system is running, the parallel port blocks the
incoming file from erasing the file you are running. When the file is finished running or
you PAUSE the file, the port opens and allows the new file to replace the current file. Be
careful when using this feature.
AUTOFOCUS
The SELECT button will toggle this setting ON (AUTOFOCUS enabled) and OFF
(manual focus enabled). Refer to the FOCUSING METHODS section on how to use this
feature.
AIR ASSIST

OPTIONS and ACCESSORIES section of the manual for more information.
DUAL HEAD
Dual Head is also an optional accessory. If you have purchased this option, please refer
to the OPTIONS and ACCESSORIES section of the manual for more information.
