The “PORTS” submenu
Two ports are provided on the right side of the system for interface with a computer, a
serial and a parallel port. Only one port can be used at a time. To activate a port,
select “PORTS” from this menu and one of the following sub menus will appear:
Or
The menu that appears indicates the currently active port on the laser system. To
switch to the other port press the “SELECT” key. In order to use the “SERIAL” port the
communication settings
MUST match those of the computer. Refer to the computer’s
hardware and software manuals for details on setting up the computer’s serial port.
If using the “SERIAL” port, select the fastest possible “BAUD RATE” for communication
since this effects how quickly the computer can send files to the laser system. For
“BAUD RATES” of “9600” and above, set the number of “STOP BITS” on the computer
to a higher value than the number of “STOP BITS” selected on the laser engraving
machine. For example if the number of “STOP BITS” on the laser engraving system is
set to “1”, then set the computer’s stop bits to “1.5” or “2”.
“PARITY” of the laser system and the computer
MUST match exactly and the choices
are “ODD”, “EVEN”, or “NONE”. Pressing the “SELECT” key while the cursor is on
“PARITY” will toggle through these choices.
