Moxa TCC-100: Industrial RS-232/422/485 Converter

Automatic Data Direction Control (ADDC)

• ADDC 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 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 incorporates a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. If a device’s baud rate is changed, the signal will still be transmitted through the RS-232 to RS-422/485 converter without problem.

RTS/CTS RS-422 Handshaking Signal

• TCC-100 provides RTS and CTS signal for RS-422 handshaking, reducing the chance of data error.

2KV Optical Isolation Protection

• TCC-100i 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 on the other side. 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.
