TCF-142 series optical-electrical converters can convert serial RS-232 or RS-422/485 signals to optical signals, support point-to-point or optical ring mode, support baud rate auto-detection, anti-current shock/chemical corrosion, and the maximum transmission distance is 40km.
The TCF-142 Series is a serial‑to‑fiber converter that supports point‑to‑point and fiber‑ring modes, extending RS‑232/422/485 transmission distances up to 40 km for single‑mode and 5 km for multimode fiber. It features automatic baud‑rate detection and Moxa’s ADDC® hardware for RS‑485 data‑flow control.
The device is housed in a compact aluminum case, operates from 12‑48 VDC, and includes DIP switches for selecting serial interface, fiber mode, and ring or point‑to‑point operation. Detailed specifications, wiring diagrams, and optional model variants are provided in the manual. This manual is written in Chinese.
