This manual covers the setup, configuration, and firmware upgrade procedures for the CNC4PC M1 Modbus Serial Server and its expansion boards.
The CNC4PC M1 is a flexible, FPGA-based Modbus Serial Server designed for industrial environments. It supports 32 inputs and 32 outputs, including discrete, analog, and encoder inputs, and allows for the use of various expansion boards to customize I/O requirements. The system features status LEDs and supports RS232/RS485 communications with upgradeable firmware accessible via HyperTerminal.
| Inputs/Outputs | 32 inputs and 32 outputs |
|---|---|
| Analog Inputs | Up to 8 |
| Encoder Inputs | Up to 6 |
| Default Modbus Address | 1 |
| Default Baud Rate | 115,200 |
| Encoder Counter Range | 65,536 steps |
The default Modbus address for the board is 1, but it can be changed via the configuration menu.
Place the core board in an expansion board, connect a serial cable to the computer, and press 'U' in HyperTerminal to update.
The discrete I/Os on the expansion boards take +5vdc ttl signals.
