TCF-142 Series
RS-232/422/485 to fiber converters
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
The TCF-142 converters can automatically detect the serial baudrate.
This is an extremely convenient feature. Even if a device’s baudrate
The TCF-142 converters 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.
fiber) or up to 40 km (TCF-142-S with single-mode fiber). 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.
is changed, the signal will still be transmitted through the media
converter without any data loss.
Introduction
Ring Operation
Automatic Baudrate Detection
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
handshaking signal.
