Ethernet CNC controller & data I/O board -  PoKeys57ET

PoKeys57ET is an easy-to-use Ethernet device that combines a lot of inputs and outputs. Pokeys57 provides 55 digital I/O (5V tolerant), 7 analog inputs (12-bit).

PoKeys57 can be used as CNC Motion controller or data I/O board. For use as CNC Motion Controller Plugins are available for Marc3 and Marc4. Use with e.g. PoKeysExtBusOC16CNC

All the I/O are controlled by the provided software which allows either to use the graphical user interface or advanced console type interface. The settings can be stored on the device, so no special software is needed on target system.
