2-2 Installation
• If planning to connect the laser engraving system to a computer through the parallel port,
choose a location where the computer will be placed within 6 feet of the machine since this
is the maximum recommended parallel cable length. Included with your system is a high
quality, IEEE1284 compliant, 6-foot parallel printer cable. PLEASE USE THIS CABLE
ONLY. DO NOT SUBSTITUTE IT WITH A LONGER OR LOWER QUALITY CABLE
OTHERWISE FILE TRANSMISSION ERRORS MAY OCCUR.
• If connecting an additional laser system or other printer to the same computer, we
recommend the installation of an additional parallel port into the computer. DO NOT use a
manual A/B type switch box. This creates electrical noise, which can cause an engraving
problem or can damage the laser system and/or the computer’s electronics.
• It is possible to connect your computer to the laser system via the computer’s USB port.
However, to do this, a special USB to Parallel Port adapter cable MUST be purchased. We
recommend only “Belkin” brand converter cables. This cable can be purchased through your
local computer store or purchased via the Internet through Belkin’s web site,
www.belkin.com. Follow the manufacturer’s instructions on how to install the cable.
Electrical Requirements
Please refer to the “INPUT POWER” sticker near the system’s ON/OFF switch and power inlet
for your system’s electrical requirements. Make sure that your electrical outlet is capable of
providing the proper voltage, frequency and amperage that your laser system needs.
Noisy or unstable electricity as well as
voltage spikes can cause interference and
possible damage to the electronics of the
laser system. Connect the laser system to
a dedicated electrical line if this is a
problem in your building.
An IT type of electrical supply is acceptable
if a standard power source is unavailable.
An IT power system is a power distribution
system having no direct connection to
earth, the exposed conductive parts of the
electrical installation being earthed.
Never remove the ground lead to the electrical cord and plug the system
into a non-grounded outlet. This is very dangerous and can lead to a severe,
if not fatal, electrical shock. Always plug the system into a 3 prong grounded
outlet.
