Introduction
TCC-100 Series provides isolation protection for users who need an industrial
grade interface conversion product to extend RS-232 transmission distance and
increase networking capability. Its superior industrial application design, which
includes DIN-Rail mounting, terminal block wiring, external terminal block
power, and optical isolation for system protection, makes TCC-100 Series
suitable for use in critical industrial environments. Simply put, 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
TCC-100 Series 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 Series’s
terminator is set with a DIP Switch located on the outside of the converter’s
casing.
