TCF-142 Series

Serial to Fiber-optic Converter

Quick Installation Guide

Ninth Edition, April 2008

1. Overview

Introduction

TCF-142 series (Rev. 3.1 or later) converters are equipped with a multiple

interface circuit that can handle RS-232, RS-422, and RS-485 serial

interfaces, as well as multi-mode or single-mode fiber. TCF-142

converters are used to extend serial transmission distance 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 must be configured to transmit a

particular serial interface. You cannot transmit both RS-232 and RS-485

signals at the same time.

Why Convert Serial to Fiber?

Fiber communication not only extends the communication distance, but

also provides many advantageous features.

IMMUNITY FROM ELECTRICAL INTERFERENCE: Fiber is not

affected by electromagnetic interference or radio frequency interference.

It provides a clean communication path and is immune to cross-talk.

INSULATION: Optical fiber is an insulator; the glass fiber eliminates the

need for using electric currents as the communication medium.

SECURITY: Fiber cannot be tapped by conventional electric means and

is very difficult to tap into optically.

RELIABILITY & MAINTENANCE: Fiber is immune to adverse

temperature and moisture conditions, does not corrode or lose its signal,

and is not affected by short circuits, power surges, or static electricity.

Reverse Power Protection

The Reverse Power Protection feature provides extra protection against

accidentally connecting the power cables to the wrong terminal. The

converter automatically detects which power wire is positive and which is

negative.

Ring Mode

To allow one half-duplex serial device to communicate with multiple

half-duplex devices connected to a fiber ring, you should configure the

TCF-142 for “ring mode” by setting DIP switch “SW4” to the “On”

position. The Tx port of a particular TCF-142 unit connects to the

neighboring converter’s Rx port on the ring. Note that 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. Users

should ensure that the total fiber

ring length is less than 100 km

when using either single-mode

models (TCF-142-S) or multi-mode

models (TCF-142-M).

ATTENTION

For Fiber Ring Users:

To avoid problems when setting up a fiber ring, each TCF-142 unit

making up the ring must be powered down and set to “Ring mode.” Next,

make sure all cables are connected properly, and then power up all

devices connected to the ring. After

powering up the TCF-142 units, if

the Rx LEDs of the converters are ON continuously, power down and

then power up ONE of the TCF-142 units in the ring to return the

network to normal operation.

NOTE “Ring Mode” can only be used with half-duplex applications

(i.e., RS-485 multi-drop communication).

DIP Switch Selectable Terminator

The TCF-142’s termination resistor is set with a DIP switch located on

the outside of the converter’s casing.

No Configuration Required for Baudrate Settings

The TCF-142 is compatible with any baudrate from 300 bps to 921.6

Kbps. The TCF-142 automatically converts the signal back and forth

between serial (RS-232, RS-422, or RS-485) and fiber, and does not need

to interpret the signal or the baudrate of the transmitting device. For this

reason, the TCF-142 does not have any DIP switches or jumpers for

setting the baudrate.

2. Features

3. Package Checklist

Before installing the TCF-142, verify that the package contains the

following items:

y TCF-142 Fiber Converter

y Quick Installation Guide

y 7-contact terminal block connector

y 3-contact terminal block connector

NOTE: Please notify your sales representative if any of the above items

are missing or damaged.

4. Dimensions and Appearance

TCF-142 fiber converters are easy to set up and use. The serial terminal

block of one of the converters connects to your computer, the serial

terminal block of the other converter connects to your serial device, and

the two converters are connected by fiber cable(s).

NOTE

Electrostatic Discharge Warning!

To protect the product from damage due to electrostatic

discharge, we recommend wearing a grounding device when

handling your TCF-142.
