### 4. Functionality

The ISC-1310FB-MM-SC functions as a serial-to-fiber converter, bridging traditional serial communication lines with modern fiber-optic networks. It enables long-distance, noise-immune data transmission between serial devices such as PLCs, sensors, controllers, and monitoring systems.

How It Works:
- The device receives serial data through its RS-232/422/485 port.
- Data is converted into optical signals and transmitted via the 100Base-FX fiber port.
- On the receiving end, another compatible converter or fiber device converts the optical signal back to serial data.
- DIP switches allow configuration of serial mode (RS-422 or RS-485), termination resistance, and DTE/DCE selection for RS-232.

Use Cases and Applications:
- Industrial automation and control systems
- SCADA and telemetry networks
- Transportation and railway signaling systems
- Power substations and utility monitoring
- Oil, gas, and mining communication infrastructure
- Maritime and offshore communication systems
- Factory floor device networking and remote serial device extension

Compatibility:
- Compatible with Modbus RTU/ASCII protocols and other serial communication standards.
- Works with standard fiber networking equipment supporting 100Base-FX.
