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.
