Nlereanya: C25
This manual provides detailed instructions for the installation, operation, and maintenance of the CNC4PC C25 Ethernet Smooth Stepper Terminal Board. The C25 board is designed to interface with a Smooth Stepper (from Warp9) to expand its input and output capabilities for CNC applications.
The C25 Terminal Board is designed for straightforward integration with your Smooth Stepper unit.
The C25 board features integrated sockets that allow it to plug directly onto the Smooth Stepper board. Align the connectors carefully and press firmly to ensure a secure connection. No ribbon cables are required for this primary connection.

The C25 board is designed to draw its operational power directly from the connected Smooth Stepper board. An additional external power supply for the C25 board is not required.
The board provides 34 input and output connections distributed across two ports. These connections are accessible via the blue screw terminals located along the edges of the board. Refer to the silkscreen labels on the board for specific pin assignments (e.g., GND, 5V, 1-17 for Port 1 and Port 2).

All signals on the C25 board are TTL 5VDC, ensuring compatibility with standard automation components. The built-in passive low pass filters on all inputs help to mitigate electrical noise, providing more stable signal integrity.
Once the C25 Terminal Board is securely connected to the Smooth Stepper and your external devices (motors, sensors, etc.) are wired to the appropriate screw terminals, the system is ready for operation. The C25 acts as an interface, extending the I/O capabilities of the Smooth Stepper. Configuration of the specific I/O functions (e.g., assigning pins to specific machine functions) is typically performed within the software controlling your Smooth Stepper (e.g., Mach3, Mach4).
Consult the documentation for your Smooth Stepper and CNC control software for detailed instructions on configuring and utilizing the extended I/O provided by the C25 board.
The C25 Ethernet Smooth Stepper Terminal Board is designed for reliable operation with minimal maintenance. To ensure longevity and proper function:
If you encounter issues with your C25 Terminal Board, consider the following troubleshooting steps:
For advanced troubleshooting or specific wiring diagrams, it may be necessary to consult the data sheets for individual components or contact CNC4PC support.
