In addition to enabling the use of Mach4 with any modern PC that lacks a parallel port or runs a 64-bit version of Windows, the Ethernet SmoothStepper provides a more reliable and robust communication path between your PC and CNC electronics.
It solves or greatly reduces most potential Windows-related communication issues by providing a dedicated real-time DSP (digital signal processor) to handle the precise timing of step and direction signals.
The Ethernet SmoothStepper does not require any special software drivers, simply utilizing the standard ethernet driver provided by your operating system, and supports up to (3) 25 pin ports worth of IO (simulating 3 parallel ports).
The DB25 to LPH26 ribbon cable option allows the Ethernet SmoothStepper to plug directly into all-in-one motor drivers like the MX4660 or G540.
The LPH26 ribbon cable option includes the appropriate cables for breakout boards with a 26-pin header, like the PMDX-126.
