TCF-142 SERIES: RS232/422/485 Serial-to-Fiber Converters

TCF-142 media converters are equipped with a multi-interface circuit that can handle RS-232 or RS-422/485 serial interfaces and single-mode or multi-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). TCF-142 converters can be configured to convert either RS-232 signals or RS-422/485 signals, but not both simultaneously.

### Automatic Baudrate Detection

TCF-142 converters can automatically detect the serial baudrate, which 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

TCF-142 converters can be used to connect serial devices to a fiber optic ring. To form the ring, connect the Tx port of one TCF-142 to the Rx port of an adjacent converter. Once the ring is configured, simply use the DIP switches to set the TCF-142 converters to ring mode. When a node transmits a signal, it travels along the ring until it returns to the transmitting unit, which then blocks it. With the TCF-142, you can configure fiber rings with a total circumference of up to 100 km.

### Automatic Data Direction Control

Automatic Data Direction Control (ADDC) is a hardware data flow solution developed by Moxa to manage RS-485 data direction. ADDC automatically detects and controls the RS-485 data direction, eliminating the need for handshaking signals.
