Data Sheet
Included Components
• Driver box with 4 motor cables
• 3.7 amp, 24 volt power supply with cord
• 25-pin parallel cable
• 2 CD set with Linux/EMC2, utilities and
instructions
• Two spare fuses
Minimum Computer Requirements
In order to install and run a Linux based system from the
CD's provided it is recommended the computer have at
least the following minimum specifications:
• Processor speed: 800 MHz or faster (Pentium III
class or equivalent processor)
• RAM: 512 Mb (Sherline provides 1 Gb)
• Hard Drive: 20 Gb or larger
• 25-pin parallel port (printer port)*
• Laptop computers are not recommended

Disclaimer
Because programs are constantly evolving, Sherline
cannot guarantee that any computer other than the ones
we build and test specifically to run Linux and EMC2
will work with this driver box and software, even if
it meets the requirements set forth above and on the
LinuxCNC web site. In cases where the driver box does
not perform properly with a computer you supply, your
least expensive choice in the long run may be simply
to purchase a computer from Sherline that is designed
specifically to run this operating system and program. In
order to save money, some companies producing single-
board computers do not provide the necessary drivers
to run Linux/EMC2. Sherline cannot be responsible for
analyzing problems with operation of this driver box
when used with a non-Sherline computer.
*NOTE: A 25-wire parallel port is required because
EMC2 is designed to be capable of running up to six
axes simultaneously. Even though the Sherline driver
box only uses four of those axes at one time, a 2-wire
serial USB port cannot transmit data to multiple axes
fast enough for glitch-free CNC operation.

CAUTION! When unplugging axis and motor cables, always grip
the plastic connector. Do not pull on the wires themselves.
