USB and Ethernet Mach3 motion controller PLCM-E3

[Purelogic R&D]

Sorry still doesn't explain what it does.

Mach3 motion controllers all have similar principles which are due to Mach3 architechture.
It does:
1) receive and buffers trajectory info from Mach3 by USB or Ethernet.
2) Process this info, transforming it to STEP/DIR/ENABLE pulses, generate them on it's "out" pins
3) receive and process signals from "in" pins
You just connect your BOB or multichannel driver to PLCM(using DB25 cable), PLCM to PC.
So, using motion controllers you decrease load on PC's CPU, system become insensitive to Windows interrupts, you get stable impulses on pins(motors rotates more smoothly) and so on.
