PoKeys57CNC USB and Ethernet CNC Controller. 

PoKeys57CNC USB and Ethernet CNC Controller Board is a blend between general-purpose PoKeys device and motor controller. The device is targeted primarily for controlling up to 8 STEP/DIR signal-driven motors (stepper motors, servo drives, etc.) in various applications with the addition of powerful PoKeys device features. The device contains dedicated connectors for connections with motor drivers, pendants, (HD44780-compatible) LCD module, etc. In addition, 5 analog inputs with 12-bit resolution are available. The device also features four galvanically-isolated open-collector outputs and isolated 0 to 10 V analog output.

The device runs the PoIL core and is fully compatible with PoBlocks graphical programming software, bringing Programmable Logic Controller to a motor controller board. PoBlocks can be used to simply automate different peripherals and interchange data with other software applications that are using the PoKeys57CNC USB and Ethernet CNC Controller Board device.

PoKeys USB products integrate support for virtual USB keyboard and USB joystick, which can be used to emulate a standard USB keyboard and joystick. Digital input pins can be mapped to the virtual keyboard and joystick keys, while analog inputs can be mapped to virtual joystick axes. The configuration is simple by using our intuitive graphical PoKeys configuration application, where each function can also be tested.

A dedicated PoExtBus/PoNET connector can be used to extend the number of digital outputs for additional 80 outputs in the form of either relay outputs or open-collector outputs. It can also be used to connect various additional peripherals (e.g. PoKeysKBD48CNC pendant) and I2C sensors.

PoKeys57CNC USB and Ethernet CNC Controller Features:

  • Supported by Mach4 and Mach3 PoKeys plugins
  • Compatible with USB 1.1/2.0 HID standard,

  • Dedicated connector for HD44780-based character LCD support (up to 4×20 characters),
  • Dedicated connector for PoPendant1
  • PoExtBus support for adding up to 10 external shift registers (e.g. PoExtBusOC16, PoExtBusRE, etc.),
  • PoNET devises support (48-key CNC keyboard),
  • fail-safe support in case of communication interruption,
  • support for up to 100 sensors, that can be connected to I2C bus, 1-wire bus, or on the general-purpose analog inputs,
  • intuitive and user-friendly software,
  • third-party support via communication DLL library and extensive protocol specification document that allows porting to other systems.

PoKeys57CNC USB and Ethernet CNC Controller Requirements:

  • Ethernet or USB connection between the host computer and PoKeys57CNC device
  • 6-26 V DC power supply with 2.5 W or more. If any additional peripheral is connected to PoKeys57CNC, more power is required.
  • Included software requires Windows 2000/XP/Vista/Windows 7/8/10 with .NET framework 3.5 installed
