PoKeys57CNCdb25 is an USB CNC controller replacing LPT (parallel port)
There are a lot of older CNC controllers with only LPT (parallel port) based control signals input connector. PoKeys57CNC is an USB CNC controller replacing LPT port. Moreover it allows a quick migration from LPT to USB CNC controller replacing LPT. Although small, the device is adjustable and as such requires no complex knowledge on device programming.
PoKeys57CNCdb25 can control up to 4 STEP/DIR signal driven motors (stepper motors, servo drives, etc.) in various applications. The device features 12 digital outputs and 5 digital inputs in total. Four of the digital outputs can be configured to operate as PWM (pulse-width modulated) output.
Features of LPT CNC controller
- Compatible with USB 1.1/2.0 HID standard,
- standard USB keyboard simulation (with triggering support for up/down keys),
- 12 digital outputs (8 are used for step/direction output signals)
- 5 digital inputs with pull-up resistors
- high performance 4-axis 125 kHz pulse engine,
- up to 4 high-speed fully configurable PWM outputs (25MHz PWM timer)
- fail-safe support in case of communication interruption,
- intuitive and user-friendly software,
- third-party support via communication DLL library and extensive protocol specification document that allows porting to other systems.
PoKeys USB products integrate support for virtual USB keyboard and USB joystick. Emulation of the standard USB keyboard is integrated. Digital input pins can be mapped to virtual keyboard and joystick keys. Configuration is simple by using our intuitive graphical PoKeys configuration application. Above all each function can also be tested.
- USB connection between host computer and PoKeys57CNCdb25 device
- Included software requires Windows 2000/XP/Vista/Windows 7/8/10 with .NET framework 3.5 installed

Support for PoBlocks graphical programming software
Third-party application developers that are adding the support for PoKeys devices, are encouraged to use the supplied communication DLL that can be simply used in the different .NET framework based applications and various other programming languages that provide support for ActiveX interface. There is even an open-source cross-platform C library available at https://bitbucket.org/mbosnak/pokeyslib.
For developers who wants to communicate with PoKeys directly, extensive documentation about device communication protocol is avaiable for download free of charge from on product webpage.
