### 4. Functionality
The NF116 functions as a serial port expansion interface, converting a single high-density connection from a Rayon PCI multiport card into 16 independent RS232 ports. Each port operates as a standard COM interface, supporting asynchronous serial communication for data acquisition, industrial control, POS systems, and communication servers.
Operation Principle:
- The NF116 connects to a host PCI card (e.g., P640NU) via an A640 cable.
- The built-in 16C554 UART controller manages data buffering and transmission for each port.
- Each port supports full-duplex RS232 communication with hardware and software flow control.
- Multiple NF116 boxes can be daisy-chained to expand total port count up to 64 per system.
Typical Applications:
- Industrial automation and process control systems
- Data acquisition and instrumentation networks
- POS and retail terminal clusters
- Serial device servers and communication hubs
- Laboratory and test equipment interfacing
- Legacy system integration requiring multiple COM ports
