Overview

Introduction

TCF-142 series 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

odels (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.

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 50 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.

Features

•“Ring” or “Point to Point” transmission

•Extend RS-232/422/485 transmission distance:

up to 40 km with single-mode—TCF-142-S Series

up to 5 km with multi-mode—TCF-142-M Series

•Compact size

•Decrease signal interference

•Protect against electronic degradation and chemical corrosion

•Supports baudrates up to 921.6 kbps

•Extended operating temperature from -40 to 75°C (for “T” models)

Package Checklist

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

following items:

•1 TCF-142 media converter

•Power jack to 3-pin terminal block adaptor

•Stick-on pads

•Quick installation guide (printed)

•Warranty card

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

are missing or damaged.

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.

Wiring Examples

Connecting the Power Supply

Before using the TCF-142, first connect the DC power supply to the power

supply terminal block located on the TCF-142’s bottom panel.

The S1 DIP Switch is located inside the TCF-142. When the TCF-142 is in

RS-485 mode, use this DIP switch to configure RS-485 data direction

control, data format, and baudrate. When the TCF-142 is in RS-232/422

mode, the S1 DIP switch cannot affect RS-232/422 communication.
