Moxa TCF-142-S-ST Serial TCF-142-S-ST

RS-232/422/485 to optical fiber media converters
The TCF-142 media converter is 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 fiber) or up to 40 km (TCF-142-S with single-mode fiber). The TCF-142 can be configured to convert either RS-232 signals, or RS-422/485 signals, but not both at the same time.

Automatic Baudrate Detection
The TCF-142 can automatically detect the serial baudrate. This is an extremely convenient feature. Even if a device�s baudrate is changed, the signal will still be transmitted through the media converter without any data loss.

Ring Operation
The TCF-142 can be used to connect serial devices to a fiber ring. To form the ring, connect the Tx port of one TCF-142 to the Rx port of a neighboring converter. Once the ring is set up, simply use the DIP switches to configure the TCF-142 converters for �ring mode.� When one node transmits a signal, the signal travels around the ring until it returns back to the transmitting unit, which then blocks the signal. With the TCF-142, you can set up fiber rings that have a total circumference of up to 100 km.

Automatic Data Direction Control (ADDC�)
ADDC� is a patented hardware data flow solution developed by Moxa to handle RS-485 data direction control. ADDC� senses and controls RS-485 data direction automatically, making it unnecessary to use the hand shaking signal.
