TCF-142 overview

  • Three way communication, RS-232, RS-422/485 and optical fibre
  • "Ring" and "Point-to-Point" transmission
  • Extend RS-232/422/485 transmission up to 40km with single-mode and 5km with multi-mode
  • SC and ST type fibre connectors
  • RS-232/422/485 via terminal block
  • Wide 12V to 48V DC power
  • Extended -40°C to +75°C wide operating temperature range (-T models only)
The TCF-142 media converters are equipped with a multiple interface circuit that can handle RS-232 or RS-422/485 serial interfaces and multi-mode or single-mode fiber. TCF-142 converters are used to extend serial transmission up to 5 km (TCF-142-M with multi-mode fibre) or up to 40 km (TCF-142-S with single-mode fibre).

The TCF-142 converters can be configured to convert either RS-232 signals, or RS-422/485 signals, but not both at the same time.

The TCF-142 series can also automatically detect the serial baud rate. This is an extremely convenient feature as even if a device’s baudrate is changed, the signal will still be transmitted through the media converter without any data loss.
