Description
Moxa TCF-142-M-ST-T RS-232/422/485 to Fiber Optic Converter, ST Multi-mode,-40 to 75, TCF-142 Series, Wall Mount
Moxa TCF-142-M-ST – RS-232/422/485 to Fiber Optic Converter. ST Multi-mode.
“Ring” and “Point- to-Point” transmission
Extends RS-232/422/485 transmission up to:
• 40 km with single-mode—TCF-142-S
• 5 km with multi-mode—TCF-142-M
Decreases signal interference
Protects against electrical interference and chemical corrosion
Supports baudrates up to 921.6 kbps
Wide temperature models available (-40 to 75°C)
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 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.
Automatic Baudrate Detection
The TCF-142 converters 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 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.
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.
