Newport 860-C2 motion controller. Tested with actuators, partially functional, and in good physical condition.

There is an issue with the channel 1(2) velocity / step size adjustment for reverse direction. It appears as if the zero-point is shifted and, for the lower half of the range, actuators actually move on the opposite (forward) direction. Repair or use as-is.

The 860-C2 is a 2-axis motion controller designed to drive both the 860A-1616 series low speed actuators (860A-025, 05, 05MM, 1, 2, and 4), as well as the 860A-1624 series high speed actuators (860A-1HS and 2HS). The 860-C2 will also drive the RSX and RSA motorized rotary stages. Two axes may be controlled simultaneously, in either RUN or JOG mode.

Up to four motion devices can be hooked up to the controller, certain pairs of them can be controlled simultaneously (see user manual for details). Computer interface is via parallel port.
