Parameters Logic high levels should be greater than 2 volts.
Logic low should be less than 1/2 volt.
Step pulses are active low.
Step pulses should be at least 22 microseconds long.
The lines labeled as LinuxCNC inputs or outputs can be disregarded in other systems.
For use with software other than LinuxCNC, make sure your software addresses the correct I/O lines for step and direction as shown below. Sherline is not able to provide assistance for other programs. For help with the LinuxCNC software, see http://www.linuxcnc.org/
We recommend at least an 800 MHz Pentium class computer or faster for use with the frequency mode.
In operation, the power to the motors will be reduced to half current after 3 seconds of inactivity. This can be changed to 1/4 power with a jumper on H1.
