1. Introduction

The TCC-100 series consists of RS-232 to RS-422/485 media converters.

The “I” versions, the TCC-100I and TCC-100I-T come with 2 kV isolation

protection.

Overview

Many important devices used in today’s industrial environment are still

designed for use with an RS-232 interface. The reason is due in part to

tradition, and in part to convenience. RS-232 hardware is relatively easy to

design, and the devices can be readily connected to most PCs. The drawback

is that RS-232 is a point-to-point interface, and it imposes a distance

limitation of only 15 meters between the device and the computer.

To overcome these limitations, many users employ RS-232 to RS-422/485

converters, allowing RS-232 devices to connect to an industrial RS-422 or

RS-485 network and transmit data over distances up to 1.2 km. The

RS-422/485 standards overcome the distance limitation by using a

differential signal for transmitting data and control signals. Transmission

distance and multi-drop connections are not the only issues of importance

for industrial applications. In addition, housing, wiring, power supply, and

over-surge protection are also serious concerns.

The TCC-100I and TCC-100I-T models come with isolation protection for

users who need an industrial grade interface conversion product to extend

RS-232 transmission distance and increase networking capability. The

superior industrial application design, which includes DIN-rail mounting,

terminal block wiring, an external terminal block power, and optical isolation

for system protection, makes the TCC-100 series suitable for use in critical

industrial environments. Your RS-232 devices can be used as part of an

industrial RS-422/485 network, but without any hardware or software

changes.

RTS/CTS RS-422 Handshaking Signals

The TCC-100 series supports RS-422 handshaking signals. The RTS and CTS

signals help solve the RS-422 signal handshaking problem and reduce data

transmission errors.

Built-in RS-485 ADDC™ Intelligence

ADDC™ (Automatic Data Direction Control) is a Moxa technology that uses

a clever hardware solution to manage RS-485’s data flow control problem.

ADDC™ is a hardware data flow solution that automatically senses and

controls data direction, making the handshaking signal method

unnecessary.

Isolation

Moxa’s electrical isolation technology uses two photo couplers to create a

gap in each electrical signal. One photo coupler transforms the electrical

signal into a light signal, which is transmitted across a small gap, and then

the other photo coupler transforms the light back into an electrical signal. In

this way, the two electrical circuits are completely isolated from each other,

limiting the damage that could otherwise be caused by ground loops in the

electrical signal.

Reverse Power Protection

The Reverse Power Protection feature provides extra protection against

accidentally connecting the power cables to the wrong terminal. The

converter is designed to automatically detect which power wire is positive

and which is negative, and then adjust the power supply accordingly.

DIP Switch Selectable Terminator

For many products of this type, the termination resistor is set by a jumper

located inside the product’s casing, so that the user must open the casing to

disable or change the resistor’s strength. Moxa offers a better solution. The

TCC-100 series’ terminator is configured with a DIP switch located on the

outside of the converter’s casing.

Auto Baudrate Detection

The TCC-100 series incorporates a method for automatically detecting the

serial signal’s baudrate by hardware. This is an extremely convenient

feature for the user. Even if a device’s baudrate changes, the signal will still

be transmitted through the RS-232 to RS-422/485 converter without any

problem.
