Many important devices used in today's industrial environment are still designed for use with an RS-232 interface. However, 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.

TCC-100/100I is an isolated RS-232 to RS-422/485 converter designed 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-100/100I 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.

ADDC™ (Automatic Data Direction Control)
ADDC™, a MOXA leading technology, uses a clever hardware solution to take care of the RS-485 data flow control problem. The RS-485 standard originally used half-duplex communication and handshaking signals such as RTS/CTS to control the direction of data flow. The TCC-100/100I converter uses embedded ADDC™ technology, a hardware data flow solution, to automatically sense and control data direction, making the handshaking signal method obsolete.

Auto Baud Rate Detection
TCC-100/100I incorporates a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if a device's baud rate is changed, the signal will still be transmitted through the RS-232 to RS-422/488 converter without problem.

RTS/CTS RS-422 Handshaking Signal
TCC-100/100I provides an RS-422 handshaking signal support. The RTS and CTS signals provide an RS-422 handshaking signal, reducing the chance of data error.
