TCF-142 Series

RS-232/422/485 to fiber converters

Features and Benefits

• Ring and point-to-point transmission

• Extends RS-232/422/485 transmission up to 40 km with single-mode (TCF-

142-S) or 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 for -40 to 75°C environments

Introduction

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, 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

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 handshaking signal.
