Introduction
RTS/CTS RS-422 Handshaking Signals
TCC-100/100I provides RS-422 handshaking signal support. 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), a Moxa leading technology, 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 obsolete.
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 power surges 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. TCC-100/100I's
terminator is set with a DIP Switch located on the outside of the converter's
casing.
Auto Baud Rate Detection
TCC-100/100I incorporates a method for automatically detecting the serial
signal's baud rate by hardware. This is an extremely convenient feature for the
user. Even if a device's baud rate changes, the signal will still be transmitted
through the RS-232 to RS-422/488 converter without any problem.
