### 4. Functionality

The ISC‑1310FB‑SS‑SC functions as a serial‑to‑fiber media converter, bridging legacy serial communication devices with modern fiber‑optic networks. It converts electrical serial signals (RS‑232/422/485) into optical signals for transmission over long distances, mitigating electromagnetic interference and signal degradation.

Operation:
- The device automatically detects the serial interface type and baud rate.
- Data received on the serial port is converted to optical signals and transmitted via the SC single‑mode fiber port.
- The reverse process occurs for data received from the fiber link.
- DIP switches allow manual configuration of interface mode, termination, and DTE/DCE roles.

Use Cases & Applications:
- Industrial automation and control systems
- SCADA and telemetry networks
- Transportation and railway signaling
- Power substations and utility monitoring
- Oil, gas, and mining communication systems
- Remote serial device connectivity over long distances

Compatibility:
- Compatible with standard RS‑232, RS‑422, and RS‑485 devices such as PLCs, sensors, controllers, and HMIs.
- Supports Modbus RTU/ASCII communication over serial and fiber links.
- Integrates seamlessly with ORing’s industrial Ethernet and serial networking solutions.

### 6. Installation & Setup

Mounting Options:
- DIN‑Rail Installation:
1. Attach the DIN‑rail kit to the back of the converter using screws.
2. Slide the unit onto the DIN‑rail until it clicks securely.
- Wall‑Mount Installation:

- RS‑232 pin assignments (DB9):
- Pin 1: DCD
- Pin 2: RXD
- Pin 3: TXD
- Pin 4: DTR
- Pin 5: SG (Signal Ground)
- Pin 6: DSR
- Pin 7: RTS
- Pin 8: CTS
- Pin 9: RI

- RS‑422/485 (Green): Serial link active and data transmitting

Safety Considerations:
- Ensure adequate airflow around the device to prevent overheating.
- Avoid mechanical stress or uneven loading when mounted on DIN‑rail.
- Verify that the power supply circuit is not overloaded.
