4. Functionality

The FTC‑6011 converts serial communication signals (RS‑232/422/485) into optical fiber signals, enabling long‑distance, noise‑immune data transmission. The Auto‑Identify and Auto‑Switch capabilities allow the unit to automatically determine the connected serial protocol without manual configuration. Auto baud detection further simplifies interoperability when devices operate at varying communication speeds.

The device uses SUNIX AHDC/CS™ technology for automatic RS‑485 2‑wire directional control, eliminating the need for software‑based flow control. Fiber transmission significantly enhances immunity to electrical interference, lightning, electromagnetic noise, and ground potential differences.

Primary Use Cases include:
• Industrial automation and control systems
• Remote equipment monitoring
• Factory communication networks
• SCADA systems
• Electrical substations and high‑EMI environments
• Long‑distance industrial serial links (up to 80 km)

5. Components & Accessories

Included Components:
• FTC‑6011 media converter unit
• DIN rail mounting kit
• Wall mount bracket

Connectors:
• Serial: Removable 3‑pin terminal block for RS‑232/422/485
• Power:

6. Installation & Setup

Installation options include DIN rail mounting for control cabinets or wall mounting for fixed infrastructure. The rugged IP30 metal case provides stability and durability in environments with vibration, shocks, or temperature variations.

Setup involves:
• Connecting power through the terminal block or DC jack
• Selecting RS‑422/485 mode through DIP switches
• Connecting the serial interface
• Attaching the appropriate fiber cable (SC multi‑mode or single‑mode)
• Automatic detection of baud rate and RS‑422/485 mode minimizes configuration

No software drivers are required, and the device automatically negotiates direction control for RS‑485.
